How to Make Frankenstein Cake
Step 1: Prepare Your Baking Pans
Start by preheating your oven to 350°F (175°C). Grease your cake pans with butter or non-stick spray and line them with parchment paper. This ensures that your cakes come out easily without sticking.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the cake flour, cocoa powder, baking soda, and salt. This step is crucial as it evenly distributes the leavening agents throughout the flour.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the unsalted butter and granulated sugar until light and fluffy. This process incorporates air into the mixture which helps create that lovely light texture in your cake.
Step 4: Add Eggs and Wet Ingredients
Next, add the eggs one at a time while continuing to mix. Then slowly incorporate the buttermilk and oil until combined. Don’t forget to add those vibrant squirts of green gel food coloring!
Step 5: Combine Dry and Wet Ingredients
Gradually add your dry mixture to the wet ingredients until just combined. Overmixing can lead to dense cakes, so be gentle!
Step 6: Bake
Divide your batter evenly between prepared pans. Bake for about 28 minutes or until a toothpick inserted comes out clean. Allow them to cool completely before frosting.
Step 7: Prepare Cream Cheese Buttercream
While your cakes cool down, whip up that delicious cream cheese buttercream! Beat together softened butter and cream cheese until smooth. Gradually add powdered sugar followed by vanilla extract and whipping cream until light and fluffy.
Step 8: Assemble Your Cake
Place one layer on your greaseproof cake board. Spread a generous amount of cream cheese buttercream on top before placing the second layer on top. Use remaining frosting to coat the entire cake smoothly.
Step 9: Decorate
Time for some fun! Use piping bags fitted with different tips to create monster features like eyes and scars using black gel food coloring. Don’t be shy; let your creativity shine!
And there you have it—a delightful Frankenstein Cake ready to impress! Enjoy every bite of this spooky yet scrumptious treat!
Pro Tips for Making Frankenstein Cake
Creating the perfect Frankenstein cake can be a fun and rewarding experience, especially with a few handy tips to guide you along the way!
- Use Room Temperature Ingredients: Ensuring your butter, eggs, and buttermilk are at room temperature allows for better emulsification and a smoother batter, resulting in a moist and fluffy cake.
- Don’t Overmix the Batter: Mixing just until combined helps maintain the cake’s light texture. Overmixing can lead to a dense cake that doesn’t rise as beautifully.
- Level Your Cake Layers: After baking, use a serrated knife to level your cake layers. This gives you a more professional-looking finish and makes stacking easier.
- Chill the Buttercream: If your cream cheese buttercream feels too soft, pop it in the refrigerator for about 15 minutes before frosting. This will make it easier to spread and pipe onto your cake.
- Experiment with Colors: Feel free to get creative with colors! You can add purple or orange accents to celebrate Halloween even more vibrantly.
How to Serve Frankenstein Cake

- Edible Eyes: You can find these fun decorations at craft stores or bakeries. Placing them on top gives your cake that spooky touch!
- Mint Leaves: Fresh mint leaves not only add color but also provide a refreshing contrast to the rich flavors of the cake.
Side Dishes
- Spooky Fruit Salad: A mix of seasonal fruits like oranges, apples, and grapes can balance out the sweetness of the cake while adding a festive touch.
- Pumpkin Soup: This warm and creamy soup is perfect for fall gatherings and serves as an excellent appetizer before indulging in dessert.
- Cheesy Garlic Breadsticks: Crunchy on the outside and soft on the inside, these savory breadsticks are great for those who want something hearty alongside their sweet treat.
