How to Make Frankenstein Cake
Creating this fun and delicious Frankenstein Cake is easy when you follow these steps!
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare two round cake pans by greasing them lightly with butter and lining them with parchment paper.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together:
1. The cake flour.
2. Cocoa powder.
3. Baking soda.
4. Fine salt.
Set aside once mixed well.
Step 3: Cream Butter and Sugar
In another mixing bowl, beat the unsalted butter until creamy. Gradually add granulated sugar while continuing to beat until light and fluffy.
Step 4: Add Eggs and Wet Ingredients
Add eggs one at a time to the creamed mixture, mixing well after each addition. Then add buttermilk, vegetable oil, green gel food coloring, vanilla extract, and white vinegar. Mix until well combined.
Step 5: Combine Dry and Wet Mixtures
Gradually add the dry ingredients into the wet mixture. Stir gently until just combined; be careful not to overmix.
Step 6: Bake the Cakes
Divide the batter evenly between the prepared pans. Bake in the preheated oven for about 28 minutes or until a toothpick inserted comes out clean. Let them cool in pans for about ten minutes before transferring them to wire racks to cool completely.
Step 7: Prepare Cream Cheese Buttercream
In a bowl, beat together unsalted butter and cream cheese until smooth. Gradually add powdered sugar while mixing on low speed. Add vanilla extract, salt, and heavy whipping cream; mix well until fluffy.
Step 8: Assemble Your Cake
Once cooled, place one layer on your cake board. Spread a generous amount of cream cheese buttercream on top before adding the second layer. Frost the entire cake with remaining buttercream.
Step 9: Decorate
Use green gel food coloring for accents on your cake’s outer surface as needed. Use black gel food coloring for eyes or other spooky decorations as desired.

How to Perfect Frankenstein Cake
To ensure your Frankenstein cake turns out perfectly every time, keep these tips in mind.
- Bold Colors: Use gel food coloring instead of liquid to achieve vibrant green layers that pop visually.
- Room Temperature Ingredients: Ensure butter, eggs, and buttermilk are at room temperature for better mixing and texture.
- Sift Dry Ingredients: Sifting flour and cocoa powder helps eliminate lumps and ensures an even texture throughout the cake.
- Proper Measuring: Use a kitchen scale for accuracy when measuring flour and sugar, especially if you’re adjusting serving sizes.
- Cool Completely: Allow the cake layers to cool fully before frosting; this prevents melting the buttercream.
- Chill Frosting: If the cream cheese buttercream becomes too soft while decorating, refrigerate it briefly before use.

- Pumpkin Soup: A warm, creamy pumpkin soup adds seasonal flavors that complement the sweetness of the cake.

Common Mistakes to Avoid
When making the Frankenstein Cake, it’s crucial to avoid common pitfalls that can affect the final result. Here are some mistakes to watch out for:
-

Using Old Baking Powder or Soda: Expired leavening agents may not provide enough rise. Always check the expiration date before use.
