How to Make Frankenstein Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare two round cake pans by greasing them with butter and lining them with parchment paper.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together:
1. Cake flour
2. Cocoa powder
3. Baking soda
4. Salt
Step 3: Cream Butter and Sugar
In another bowl, beat together unsalted butter and granulated sugar until light and fluffy. This should take about 3-5 minutes.
Step 4: Add Eggs and Wet Ingredients
Add eggs one at a time to the butter mixture, mixing well after each addition. Then add buttermilk, vegetable oil, food coloring, vanilla extract, and vinegar. Mix until well combined.
Step 5: Combine Dry and Wet Mixtures
Gradually add the dry ingredient mixture into the wet ingredients. Mix until just combined; do not overmix.
Step 6: Bake
Divide the batter evenly between the prepared pans. Bake in preheated oven for about 28 minutes or until a toothpick comes out clean when inserted into the center.
Step 7: Cool Cakes
Allow cakes to cool in pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 8: Make Buttercream Frosting
While cakes are cooling, beat together unsalted butter and cream cheese until smooth. Gradually add powdered sugar while mixing on low speed until fully combined. Add vanilla extract and salt; mix well. Adjust consistency with heavy whipping cream if necessary.
Step 9: Assemble Cake
Once cooled, place one cake layer on a greaseproof board. Spread a layer of frosting on top before adding the second layer. Frost the entire outside of the cake smoothly.
Step 10: Decorate
Use piping bags with various tips to create fun designs on your Frankenstein cake using colored gel food coloring for accents. Enjoy your spooky creation!

How to Perfect Frankenstein Cake
To ensure your Frankenstein cake turns out perfectly every time, consider these helpful tips:
-
Measure Accurately: Precision in measuring ingredients is key to achieving the perfect texture and flavor.
-
Use Room Temperature Ingredients: Ensure eggs, butter, and buttermilk are at room temperature for better incorporation and fluffiness.
-
Don’t Overmix: Gently mix your batter until just combined to avoid dense cakes; overmixing can lead to tough textures.
-
Check Oven Temperature: Use an oven thermometer to confirm your oven’s temperature is accurate; baking at the wrong temperature can affect rising.
-
Cool Completely: Allow your cake layers to cool completely before frosting; this prevents melting and helps maintain structure.
Best Side Dishes for Frankenstein Cake

Spooky Veggie Platter: Create a colorful array of veggies arranged like a haunted graveyard with dip served in mini cauldrons.
Common Mistakes to Avoid
When making your Frankenstein Cake, be mindful of these common pitfalls to ensure a successful baking experience.
- Skipping Ingredient Room Temperature: Using cold ingredients can affect the batter’s texture. Always let eggs and butter sit out for at least 30 minutes before use.
- Overmixing the Batter: Overmixing can lead to a dense cake. Mix just until the dry ingredients are incorporated for a light and airy texture.
- Not Measuring Ingredients Accurately: Accurate measurements are crucial for baking success. Use a kitchen scale or measuring cups carefully to avoid errors.
- Ignoring Oven Temperature: Baking at the wrong temperature can result in uneven baking. Always preheat your oven and use an oven thermometer if necessary.
- Underestimating Cooling Time: Cutting the cake too early can cause it to crumble. Allow the cake layers to cool completely before frosting.
