How to Make Frankenstein Cake
Step 1: Prepare Your Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour three round cake pans to prevent sticking.
Step 2: Mix Dry Ingredients
In a bowl, whisk together the cake flour, cocoa powder, baking soda, and salt until well combined.
Step 3: Cream Butter and Sugar
In a separate mixing bowl, beat the unsalted butter with granulated sugar using an electric mixer until light and fluffy. This should take about 5 minutes.
Step 4: Add Eggs and Wet Ingredients
Add eggs one at a time to the butter mixture. Mix well after each addition. Then add buttermilk, oil, vanilla extract, vinegar, and green gel food coloring. Mix until just combined.
Step 5: Combine Dry and Wet Mixtures
Gradually add the dry ingredients to the wet ingredients. Mix on low speed until everything is incorporated and no lumps remain.
Step 6: Bake the Cakes
Divide the batter evenly between the prepared pans. Bake in preheated oven for about 28 minutes or until a toothpick comes out clean. Let them cool completely before frosting.
Step 7: Make Cream Cheese Buttercream
While cakes are cooling, prepare your buttercream by beating together unsalted butter and cream cheese. Gradually add powdered sugar while mixing on low speed. Add salt and whipping cream for desired consistency.
Step 8: Assemble Your Cake
Level off your cooled cake layers if necessary. Place one layer on the greaseproof cake board. Spread an even layer of cream cheese buttercream on top before adding the next layer. Repeat until all layers are stacked.
Step 9: Frost the Exterior
Use an offset spatula to apply a thin crumb coat over the entire cake. Chill for about 30 minutes before applying a thicker layer of frosting for decoration.
Step 10: Decorate Your Cake
Using piping bags fitted with different tips, decorate your Frankenstein cake with black gel food coloring for details like eyes or stitches. Use electric green gel food coloring for fun accents!

How to Perfect Frankenstein Cake
Achieving the perfect Frankenstein cake requires attention to detail and some baking know-how. Here are some essential tips for success.
-
Use Room Temperature Ingredients – Ensure all your ingredients, especially eggs and butter, are at room temperature for better mixing and texture.
-
Don’t Overmix – When combining wet and dry ingredients, mix just until incorporated. Overmixing can lead to a dense cake.
-
Check Doneness Early – Start checking your cake about 5 minutes before the suggested bake time. A toothpick should come out clean when inserted into the center.
-
Cool Completely Before Frosting – Allow your cake layers to cool completely before frosting. This prevents melting and sliding of the icing.
-
Color Gradually – When adding food coloring, start with a small amount. You can always add more for a vibrant green color without going overboard.
