Versatile Harry Potter Cake Recipe Base: Choose Between Classic Vanilla or Chocolate Cake

This versatile cake base can be made in either vanilla or chocolate varieties, depending on your preference. Consequently, this reliable recipe produces a moist, flavorful cake that holds up well to decorating.

Ingredients for Harry Potter Basic Cake Mix:
For Vanilla Cake:
- 3 cups (375g) all-purpose flour
- 2 cups (400g) granulated sugar
- 1 tablespoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 4 large eggs, room temperature
- 1 cup (227g) unsalted butter, softened
- 1 cup (240ml) buttermilk, room temperature
- 2 tablespoons vanilla extract
- 1/4 cup (60ml) vegetable oil
For Chocolate Variation:
- 2 3/4 cups (344g) all-purpose flour
- 2 cups (400g) granulated sugar
- 3/4 cup (75g) cocoa powder
- 2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 4 large eggs, room temperature
- 1 cup (227g) unsalted butter, softened
- 1 cup (240ml) buttermilk, room temperature
- 1 tablespoon vanilla extract
- 1/2 cup (120ml) hot coffee or hot water
- 1/4 cup (60ml) vegetable oil
Equipment Needed for Your Harry Potter Cake Base:
- Two 8-inch round cake pans
- Mixing bowls (large and medium)
- Electric stand mixer or hand mixer
- Measuring cups and spoons
- Rubber spatula
- Whisk
- Cooling rack
- Parchment paper
Instructions for Making the Perfect Cake Base:

- Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans with butter or cooking spray, then line the bottoms with parchment paper circles for easy removal.
- For the vanilla cake: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt to combine the dry ingredients. For the chocolate cake: Whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
- In the bowl of your stand mixer fitted with the paddle attachment, beat the butter and sugar together on medium-high speed until light and fluffy, about 3-4 minutes.
- Add the eggs one at a time, beating well after each addition. Then, add the vanilla extract and oil, mixing until well incorporated.
- Gradually add the dry ingredient mixture to the butter mixture in three parts, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix only until just combined after each addition to avoid overmixing.
- For the chocolate version only: Slowly pour in the hot coffee or water and mix until smooth. The batter will be somewhat thin, which is normal for a moist chocolate cake.
- Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Allow the cakes from the oven to cool in the pans for 10 minutes, then run a knife around the edges and turn them out onto a cooling rack to cool completely.
Tips for a Perfect Harry Potter Cake Base:
- For extra moisture, you can brush each cooled cake layer with simple syrup (equal parts sugar and water, boiled then cooled) before frosting.
- These cake layers can be made 1-2 days in advance. Once completely cooled, wrap each layer individually in plastic wrap and store at room temperature for one day, or in the refrigerator for up to three days.
- For longer storage, wrap the cooled cake layers in plastic wrap, then aluminum foil, and freeze for up to three months. Thaw overnight in the refrigerator before decorating.
- The chocolate version of this cake pairs exceptionally well with the butterbeer cake variation we’ll explore later in this article.
Iconic Hagrid’s Birthday Cake Recipe: Make Harry Potter’s First Birthday Cake
One of the most memorable moments in “Harry Potter and the Sorcerer’s Stone” (or “philosopher’s stone” in the UK edition) is when Hagrid presents Harry with his very first birthday cake. As fans will recall, hagrid gave harry this slightly lopsided pink cake with green writing for his 11th birthday. Now, you can recreate this heartwarming moment with our detailed hagrid’s birthday cake recipe!
Ingredients for Hagrid’s Cake:
For the Cake:
- 1 layer of the Chocolate Cake Base recipe (above)
Pink Buttercream:
- 1 cup (227g) unsalted butter, softened
- 4 cups (480g) powdered sugar
- 2-3 tablespoons heavy cream or milk
- 2 teaspoons vanilla extract
- Pinch of salt
- Pink gel food coloring (about 3-4 drops)
For the Green Writing:
- 1/2 cup of reserved buttercream
- Green gel food coloring (about 3-4 drops)
Equipment Needed:
- 8-inch cake board or serving plate
- Offset spatula
- Piping bag
- Small round piping tip (#3 or #4)
- Cake decorating turntable (optional but helpful)
Instructions for Hagrid’s Birthday Cake:
- Place your cooled chocolate cake layer on a cake board or serving plate. If using a turntable, place the board on the turntable for easier decorating.
- Prepare the pink buttercream: In a large bowl, beat the butter until smooth and creamy, about 2 minutes. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add the vanilla, salt, and 2 tablespoons of cream, then beat for 3-4 minutes until light and fluffy. Add more cream if needed to achieve a spreadable consistency.
- Add pink food coloring to the buttercream, starting with just 2-3 drops and mixing thoroughly. Add more coloring gradually until you achieve the bright pink shade seen in the movie. Remember, the color will deepen slightly as it sits.
- Before coloring all the frosting, reserve about 1/2 cup of frosting in a separate bowl for the green writing.
- Using an offset spatula, apply the pink buttercream all around and on top of the cake. For an authentic look, don’t worry about making it perfectly smooth – hagrid made this cake by hand, so a slightly rustic finish is more accurate! Leave some texture on the sides and top of the cake.
- For the green writing: Add green food coloring to the reserved frosting, mixing until you achieve a bright green color. Transfer the green frosting to a piping bag fitted with a small round tip.
- Carefully pipe “HAPPEE BIRTHDAE HARRY” onto the cake in green letters, just like in the movie. Don’t aim for perfection – slightly wobbly letters are more authentic to hagrid’s somewhat limited cake decorating skills!
- If desired, you can pipe a border around the bottom edge of the cake with the remaining pink frosting for additional decoration.
Tips for an Authentic Hagrid’s Cake:
- Watch the movie scene again for reference before decorating.
- For the most authentic look, pipe the text in all capital letters and slightly uneven, as hagrid’s spelling and handwriting aren’t perfect!
- The original cake appears to have a slightly raised, rounded top rather than being perfectly flat.
- If you want to make the exact movie version, you can add a few spots or dots of green frosting around the sides of the cake as well.
- This cake is perfect for a harry potter party centerpiece and will delight any huge harry potter fan!

To Assemble the Butterbeer Cake:
- Level your cake layers if needed using a serrated knife or cake leveler.
- Place the first cake layer on a cake board or serving plate.
- Spread a generous layer of butterscotch buttercream on top of the first layer.
- Place the second cake layer on top and repeat the process. If using three layers, add the third layer on top.
- Apply a thin crumb coat of buttercream all over the cake, then refrigerate for 15-20 minutes to set.
- Apply the final coat of buttercream, smoothing the sides and top as desired.
- If using the butterscotch drip, transfer it to a squeeze bottle or spoon and carefully apply around the top edge of the cake, allowing it to drip down the sides. Then pour the cake batter of drip over the center top and spread gently.
- Decorate as desired with additional buttercream swirls, gold sprinkles, or Harry Potter-themed toppers.
Tips for the Perfect Butterbeer Cake:
- For extra butterscotch flavor, you can brush each cake layer with a mixture of butterscotch sauce thinned with a little cream soda before frosting.
- Gold sprinkles or edible gold dust make excellent decorations that capture the magical essence of Butterbeer.
- This cake recipe works wonderfully for cupcakes too! To make cupcakes, fill liners 2/3 full and bake for 18-20 minutes.
- For a stronger butterscotch flavor, you can reduce 1 cup of cream soda down to 1/2 cup by simmering it gently on the stove, then cooling completely before adding to the recipe.

Additionally, this version is just as delicious as traditional recipes, proving that plant-based baking can be magical too!

Ingredients for Vegan Harry Potter Cake:
For the Vegan Chocolate Cake:
- 3 cups (375g) all-purpose flour
- 2 cups (400g) granulated sugar
- 2/3 cup (65g) cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 cups (480ml) plant-based milk (soy, almond, or oat work best)
- 2/3 cup (160ml) vegetable oil
- 2 tablespoons apple cider vinegar
- 2 teaspoons vanilla extract
- 1/4 cup (60ml) hot water or coffee
Vegan Pink Buttercream:
- 1 cup (227g) vegan block butter (not spreadable from a tub), softened
- 4 cups (480g) powdered sugar
- 2-3 tablespoons plant-based milk
- 1 teaspoon vanilla extract
- Pinch of salt
- Vegan pink food coloring (about 3-4 drops)
For the Vegan Green Writing:
- 1/2 cup of reserved vegan buttercream
- Vegan green food coloring (about 3-4 drops)
Equipment Needed:
- Two 8-inch round cake pans
- Mixing bowls
- Whisk and spatula
- Measuring cups and spoons
- Piping bag
- Small round piping tip
- Offset spatula
Instructions for Vegan Harry Potter Cake:
- Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
- In another bowl, combine the plant-based milk, oil, vinegar, and vanilla extract. The mixture will curdle slightly, which is normal and helps to create a moist cake.
- Pour the wet ingredients into the dry ingredients and whisk until just combined. Add the hot water or coffee and mix until smooth.
- Divide the batter evenly between the prepared cake pans and smooth the tops.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes, then turn out onto a cooling rack to cool completely.
For the Vegan Buttercream:
- In a large bowl, beat the vegan butter until smooth and creamy, about 2 minutes.
- Gradually add the powdered sugar, one cup at a time, beating well after each addition.
- Add the vanilla extract, salt, and 2 tablespoons of plant-based milk. Beat on medium-high speed for 3-4 minutes until light and fluffy. Add more milk as needed to achieve a spreadable consistency.
- Before coloring all the frosting, reserve about 1/2 cup of frosting in a separate bowl for the green writing.
- Add pink food coloring to the main portion of buttercream, starting with just 2-3 drops and mixing thoroughly. Add more coloring gradually until you achieve the desired bright pink shade.
- For the green writing: Add green food coloring to the reserved frosting, mixing until you achieve a bright green color.
To Assemble the Vegan Hagrid-Style Cake:
- Place one cake layer on a cake board or serving plate.
- If making a single-layer cake like Hagrid’s original, use just one layer. For a two-layer cake, spread a layer of pink buttercream between the layers and stack them.
- Frost the entire cake with the pink buttercream, creating a slightly rustic finish.
- Transfer the green frosting to a piping bag fitted with a small round tip.
- Pipe “HAPPEE BIRTHDAE HARRY” (or your chosen message) onto the cake in green letters.
Tips for a Perfect Vegan Harry Potter Cake:
- Check that your food coloring is vegan-friendly, as some contain insect-derived carmine or other animal products.
- Vegan block butters (like Miyoko’s, Earth Balance sticks, or Flora Plant Butter) work much better for frosting than tub-style spreads.
- For the most authentic Hagrid cake look, remember that it’s supposed to be imperfect, so don’t worry too much about getting perfectly smooth frosting or perfectly even lettering.
- This cake is best stored in an airtight container at room temperature and consumed within 2-3 days.
- Be sure to check that your sugar is vegan (not processed with bone char) if making this for strict vegans.

Frequently Asked Questions About Harry Potter Cakes
What Kind of Cake Did Hagrid Give Harry?
In the harry potter series, specifically in “Harry Potter and the Sorcerer’s Stone,” Rubeus Hagrid gives Harry a chocolate cake with pink frosting and green writing for his 11th birthday. The cake has “HAPPEE BIRTHDAE HARRY” written on it in wobbly green letters. This iconic scene marks Harry’s first-ever birthday cake and represents his introduction to the wizarding world. Additionally, despite its slightly messy appearance, the cake symbolizes the beginning of Harry’s new life beyond the neglectful Dursleys.
What Flavor is the Harry Potter Cake?
While not explicitly stated in the books, the harry potter’s birthday cake from Hagrid appears to be a chocolate cake in the movies, with pink frosting. However, within the Harry Potter fandom, many flavors have become associated with the wizarding world. For instance, butterbeer-flavored cakes have become extremely popular among fans, inspired by the beloved drink from the series. Furthermore, other magical flavors that fans often incorporate include treacle (Harry’s favorite dessert is treacle tart), pumpkin spice (inspired by pumpkin juice), and chocolate frogs.
How to Plan a Harry Potter Birthday Party?
Planning a harry potter party involves several magical elements. First, start with invitations that look like Hogwarts acceptance letters. Next, decorate your space with house colors, floating candles (battery-operated ones suspended from fishing line), and platform 9¾ signs. Additionally, organize activities like a sorting hat ceremony, potions class (simple science experiments), and a Quidditch game (adapted for non-flying players).
For food, serve themed items like Golden Snitch cake pops, chocolate frogs, Butterbeer, and of course, a harry potter cake as the centerpiece. Furthermore, goodie bags can include wands, house ties, and wizard-themed treats. Consequently, these elements create an immersive experience that any harry potter fan will love.
What Was Written on Harry Potter’s Birthday Cake?
In both the book and movie “Harry Potter and the Philosopher’s Stone” (known as “Sorcerer’s Stone” in the US), hagrid’s cake for Harry has “HAPPEE BIRTHDAE HARRY” written on it in green icing. This misspelling reflects Hagrid’s somewhat limited writing skills but also shows his genuine affection for Harry. Moreover, this cake is especially significant because it’s the first birthday cake Harry ever received, making it a powerful symbol of his new life in the wizarding world.
What Flavor is Mermaid Cake?
While not directly related to Harry Potter, mermaid-themed cakes have become popular in themed baking. Typical mermaid cake flavors include vanilla or funfetti cake with colorful blue and green swirls inside to represent ocean waters. Often, these cakes are filled with white chocolate ganache or vanilla buttercream and decorated with pearl-like sprinkles, edible glitter, and fondant or chocolate mermaid tails.
For a Harry Potter twist on a mermaid cake, you could create a cake inspired by the merpeople from the Black Lake featured in the Triwizard Tournament in “Harry Potter and the Goblet of Fire.” This could incorporate blue-green color schemes with elements like the golden egg or other tournament motifs.

- Using an offset spatula, apply the pink buttercream all around and on top of the cake. For an authentic look, don’t worry about making it perfectly smooth – Hagrid made this cake by hand, so a slightly rustic finish is more accurate! Leave some texture on the sides and top of the cake.
- Add green food coloring to the reserved frosting, mixing until you achieve a bright green color. Transfer the green frosting to a piping bag fitted with a small round tip.3-4 drops green gel food coloring
- Carefully pipe ‘HAPPEE BIRTHDAE HARRY’ (or your chosen message) onto the cake in green letters. Don’t aim for perfection – slightly wobbly letters are more authentic to Hagrid’s somewhat limited cake decorating skills!
- If desired, you can pipe a border around the bottom edge of the cake with the remaining pink frosting for additional decoration.
Notes
- For the most authentic Hagrid cake, remember that it’s supposed to be imperfect, so don’t worry about getting perfectly smooth frosting or perfectly even lettering.
- For a butterbeer variation, add butterscotch flavoring to the cake batter and replace some of the milk with cream soda. For the buttercream, add 1/3 cup butterscotch sauce to the recipe.
- To make this cake vegan: Use plant-based milk with a tablespoon of vinegar instead of buttermilk, replace butter with vegan butter or margarine, and use flax eggs (1 tbsp ground flaxseed mixed with 3 tbsp water equals one egg).
- To make this cake gluten-free: Use a high-quality gluten-free all-purpose flour blend with xanthan gum. Verify all other ingredients are certified gluten-free, particularly the cocoa powder, baking powder, and vanilla extract.
- Store the finished cake in an airtight container at room temperature for up to 3 days or refrigerated for up to 5 days. Bring to room temperature before serving for best flavor and texture.
