How to Make Frankenstein Cake
Step 1: Prepare Your Cake Batter
Start by preheating your oven to 350°F (175°C). Grease and flour two round cake pans so that our cake layers release easily. In a mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt. This step helps ensure everything combines well later.
Step 2: Cream Butter and Sugar
In another bowl, beat together the room-temperature butter and granulated sugar until light and fluffy. This process incorporates air into the mixture, making your cake light. Gradually add in your eggs one at a time, mixing well after each addition.
Step 3: Combine Wet Ingredients
In a measuring jug, mix together buttermilk, vegetable oil, green gel food coloring, vanilla extract, and white vinegar. Add these wet ingredients into your creamed butter mixture alternately with the dry ingredients. Mixing gently will keep your batter light.
Step 4: Bake Your Cakes
Divide the batter evenly between the prepared pans. Bake them in your preheated oven for about 28 minutes or until a toothpick comes out clean from the center. Allow them to cool in the pans for about ten minutes before transferring them to wire racks.
Step 5: Make Your Buttercream Frosting
While your cakes cool down completely, let’s whip up that delicious cream cheese buttercream! Beat together unsalted butter and cream cheese until creamy. Gradually add powdered sugar and mix until smooth. Add heavy cream to reach your desired consistency.
Step 6: Assemble Your Cake
Once cooled completely, level off any domed tops on your cakes with a knife. Place one layer on your greaseproof board or plate. Spread a good amount of frosting on top before adding the second layer. Crumb coat the entire cake with frosting then chill briefly.
Step 7: Decorate Like Frankenstein
Now comes the fun part! Use electric green gel food coloring to tint part of your frosting for decorating. Pipe it onto your chilled cake using various tips for texture and detail—think hair and scars! A little black gel food coloring can add personality too!
With every slice of this delightful Frankenstein Cake shared among friends or family during Halloween festivities—or any occasion—the smiles it brings are truly priceless! Enjoy baking!
Pro Tips for Making Frankenstein Cake
Making a show-stopping Frankenstein cake can be easier than you think with a few helpful tips! Here are some pro suggestions to ensure your cake turns out perfectly spooky.
- Use Room Temperature Ingredients: Always make sure your butter, eggs, and buttermilk are at room temperature. This helps create a smoother batter and ensures better mixing, leading to a moist and fluffy cake.
- Sift Your Dry Ingredients: Sifting the flour, cocoa powder, and baking soda not only removes lumps but also aerates the mixture. This results in a lighter cake that rises beautifully.
- Don’t Overmix the Batter: When combining wet and dry ingredients, mix just until incorporated. Overmixing can lead to a dense cake, which is not what we want for our delightful Frankenstein creation!
- Chill Your Buttercream: If you find your cream cheese buttercream is too soft to work with, pop it in the fridge for about 15 minutes. This makes it easier to pipe those spooky details onto your cake.
- Practice Piping Techniques: Before decorating your Frankenstein cake, practice piping on a piece of parchment paper. This will help you get comfortable with the piping bag and achieve those perfect monster features!
