How to Make Frankenstein Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour two round cake pans.
Step 2: Combine Dry Ingredients
In a large bowl, whisk together the following:
1. Cake flour
2. Cocoa powder
3. Baking soda
4. Salt
Step 3: Mix Wet Ingredients
In another bowl, beat together:
1. Unsalted butter and granulated sugar until creamy.
2. Add eggs one at a time, mixing well after each addition.
3. Incorporate buttermilk, vegetable oil, green food coloring, vanilla extract, and vinegar until well combined.
Step 4: Combine Mixtures
Gradually add the dry ingredients to the wet ingredients. Mix until just combined; do not overmix.
Step 5: Bake
Divide the batter evenly between the prepared pans. Bake for about 28 minutes or until a toothpick inserted in the center comes out clean.
Step 6: Cool Layers
Allow cakes to cool in pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 7: Prepare Buttercream
In a mixing bowl, beat unsalted butter until creamy. Add cream cheese and mix well. Gradually add powdered sugar while mixing on low speed. Add heavy whipping cream and mix until fluffy.
Step 8: Assemble Cake
Once cooled, place one layer on the greaseproof board. Spread cream cheese buttercream on top before placing the second layer on top. Apply a thin layer of frosting around the sides and top of the cake as a crumb coat. Chill briefly.
Step 9: Decorate Cake
Use remaining buttercream to fully frost the cake. Add electric green gel food coloring for accents and black gel food coloring for facial features or other decorations as desired.

How to Perfect Frankenstein Cake
Perfecting your Frankenstein Cake requires attention to detail and technique. Follow these tips for the best results.
-
Use room temperature ingredients: Ensuring your eggs, butter, and buttermilk are at room temperature helps create a smoother batter that rises beautifully.
-
Sift dry ingredients: Sifting the flour, cocoa powder, and baking soda can help prevent lumps and ensure even mixing throughout the batter.
-
Don’t overmix: Mix the cake batter until just combined to maintain a light texture. Overmixing can lead to a dense cake.
-
Check doneness properly: Insert a toothpick in the center of the cake; if it comes out clean or with few crumbs, it’s ready. Avoid opening the oven door too early.
-
Let it cool completely: Before frosting, allow the layers to cool completely on a wire rack. This prevents melting or sliding of the frosting.
Best Side Dishes for Frankenstein Cake
Pairing delicious side dishes with your Frankenstein Cake can elevate your Halloween gathering. Here are some great options.
-
Witch’s Brew Punch: A fizzy green punch made from lime soda and lime sherbet creates a refreshing drink that matches the cake’s theme.
-
Ghostly Fruit Salad: Combine melon balls, grapes, and blueberries for a colorful salad topped with whipped cream ghosts made from dollops of cream.
-
Mummy Hot Dogs: Wrap hot dogs in crescent dough strips to resemble mummies; bake until golden brown for a fun savory treat.
-
Pumpkin Spice Muffins: These muffins add seasonal flavor and pair well with sweet desserts; serve warm with butter.
-
Creepy Veggie Platter: Arrange veggies in spooky shapes accompanied by ranch dip molded into a skull or pumpkin shape.
-
Graveyard Dirt Cups: Layer chocolate pudding with crushed cookies and gummy worms for an eerie dessert that complements your cake perfectly.
Common Mistakes to Avoid
When making your Frankenstein Cake, avoid these common pitfalls to ensure a spooky success!
- Overmixing the Batter: Mixing the batter too much can lead to dense cake layers. Mix just until ingredients are combined for a light and fluffy texture.
- Ignoring Temperature Requirements: Baking with cold ingredients can affect the rise of your cake. Always use room temperature eggs and buttermilk for best results.
- Using the Wrong Food Coloring: Choosing liquid food coloring instead of gel can result in a muted color. Opt for gel food coloring to achieve that vibrant green hue.
- Not Measuring Ingredients Accurately: Inaccurate measurements can lead to an undesired outcome. Use a kitchen scale for precise ingredient amounts.
- Skipping the Cooling Time: Cutting into a warm cake can cause it to crumble. Allow your cake layers to cool completely before frosting.
