Ingredients You’ll Need

This Brain Cake Recipe relies on classic baking ingredients that come together beautifully—you want fresh buttermilk and room-temperature butter and eggs for the best texture. Also, choosing good-quality cream cheese makes a world of difference in your frosting.

• Cake Flour: Offers a tender crumb that’s perfect for a delicate cake like this one.
• Unsweetened Cocoa Powder: Balances the sweetness and gives the classic red velvet flavor.
• Baking Soda: Helps the cake rise properly and creates that velvety texture.
• Fine Salt: Enhances all the flavors, don’t skip it!
• Unsalted Butter: Use softened butter for creamier batter and frosting.
• Granulated Sugar: Sweetens the cake without overpowering the cocoa.
• Large Eggs: Act as a binder and provide richness.
• Buttermilk: Adds moisture and tang; it’s key for red velvet’s signature softness.
• Vegetable or Canola Oil: Keeps the cake moist and tender.
• Vanilla Extract or Vanilla Bean Paste: Adds depth and warmth to both cake and frosting.
• White Vinegar: Reacts with baking soda to help the cake rise and adds subtle tanginess.
• Red Gel or Liquid Food Coloring: Creates the vivid brain-like color in the cake layers.
• Full-Fat Cream Cheese: The secret to a creamy, tangy frosting that holds up well.
• Powdered Sugar: Sweetens and thickens the buttercream perfectly.
• Heavy Whipping Cream: Lightens the buttercream for a luscious texture.
• Seedless Raspberry or Strawberry Jam: Provides that creepy “blood” effect—so worth it!
• Water: Helps thin the jam slightly for easy drizzling.

Variations

I love making this Brain Cake Recipe just as it is for Halloween, but I also enjoy mixing it up a bit depending on the occasion or what I have on hand. Don’t hesitate to experiment—you can make it your own.

• Chocolate Lover’s Variation: Use dark cocoa instead of regular for a richer taste—I’ve done this when I wanted a deeper chocolate flavor, and it’s heavenly.
• Dairy-Free Option: Swap out butter and cream cheese for plant-based alternatives; I did this once for a friend’s allergy and it still came out great.
• Fruit Filling Change: Instead of raspberry jam, try cherry preserves for a different “blood” look and flavor—fresh and delicious!
• Food Coloring Swap: Use natural beet juice or powdered spirulina to create unique colors if you prefer going natural.

How to Make Brain Cake Recipe

Step 1: Mix Your Dry Ingredients

Start by sifting together your cake flour, cocoa powder, baking soda, and salt. This step is crucial because it helps to evenly distribute the cocoa and baking soda, ensuring your cake bakes up perfectly even without any lumps. I always sift twice to get that light, airy base.

Step 2: Cream Butter and Sugar

In a large bowl, beat the softened butter and sugar until the mixture is light and fluffy—this usually takes about 3-4 minutes with an electric mixer. This step traps air which will help your cake rise beautifully, so don’t rush it!

Step 3: Add Eggs and Flavors

Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then, add vanilla extract and red food coloring. I like using gel coloring because it gives a vibrant color without watering down the batter.

Step 4: Combine Wet and Dry Alternately

Alternately add your dry ingredients and buttermilk (mixed with vinegar) to the butter mixture, beginning and ending with the dry ingredients. Mix just until combined—overmixing can make the cake tough. This back-and-forth mixing keeps it tender!

Step 5: Bake the Layers

Divide batter evenly into your prepared pans and bake at 350°F (175°C) for about 25-27 minutes, or until a toothpick inserted comes out clean. I learned the hard way that opening the oven door too often can make the cake sink, so try to resist peeking until closer to the end.

Step 6: Prepare the Buttercream

While the cake cools, whip together butter and cream cheese until smooth. Add powdered sugar gradually, vanilla, salt, a splash of heavy cream and just a tiny bit of red food coloring to get that perfect pink shade. The cream cheese cuts the sweetness and keeps it creamy without feeling heavy.

Step 7: Assemble the Cake

Slice cooled cake layers into brain-shaped pieces (or carve with a template if you’re feeling creative!). Spread buttercream between layers, then add dollops of raspberry jam mixed with a little water for “oozing blood.” Coat the entire cake with the pink buttercream, piping in curved lines to mimic the brain’s texture. This is the fun part—I always get a little artistic here!

How to Serve Brain Cake Recipe

Garnishes

I like to finish this Brain Cake Recipe with a light dusting of edible glitter or pearl dust to give it a slightly eerie but elegant sheen. Sometimes small sugar “spiders” or Halloween-themed toppers make it extra fun for parties. Plus, those fresh raspberries or mint leaves on the side add a little freshness against all that sweetness.

Side Dishes

Since this cake is rich, I usually serve it with a simple cup of black coffee or an herbal tea to balance the flavors. For gatherings, I’ve paired it with spiced cider or even a fun cocktail like a blood-red sangria, which makes the theme even more festive!

Creative Ways to Present

If you’re feeling extra crafty, I’ve carved this Brain Cake in hemispheres to mimic actual brain halves, then added “veins” using piped red gel or melted chocolate. Using piping techniques to exaggerate the brain folds really wows a crowd. I once wrapped it on a platter with a faux fog machine for a Halloween party, which was a total hit.

Make Ahead and Storage

Storing Leftovers

I usually keep leftover Brain Cake wrapped tightly in the fridge for up to 4 days. The cream cheese buttercream softens even more overnight, which I personally love, but if you prefer firmer frosting, keep it chilled and bring to room temp before serving.

Freezing

I’ve successfully frozen slices wrapped individually in plastic wrap and foil for up to 2 months. When thawing, I let the pieces come to room temperature slowly in the fridge overnight to prevent condensation from making the frosting runny.

Reheating

This cake is best enjoyed cold or at room temperature, so I don’t recommend reheating it. However, if you want to warm it slightly, I give individual slices just 10-15 seconds in the microwave on low power—just enough to slightly soften but not melt the frosting.
