Ingredients You’ll Need

Each ingredient plays a key role in bringing this Brain Cake Recipe to life—moist cake layers, rich frosting, and the dramatic edible “blood.” I recommend looking for high-quality butter and cream cheese as they really shine in this cake, plus go for gel food coloring for the best vibrant hues without affecting texture.

• Cake Flour: Gives the cake its soft, tender crumb, essential for velvety red velvet texture.
• Unsweetened Cocoa Powder: Adds that hint of chocolate flavor that makes red velvet so special.
• Baking Soda & Salt: The perfect leavening and seasoning balance for the cake layers.
• Unsalted Butter: Room temperature butter helps make the batter fluffy and smooth.
• Granulated Sugar: Sweetens the cake while helping it keep a tender structure.
• Eggs: Provides structure and richness; use room temperature for best mixing.
• Buttermilk: Adds tanginess and moisture to keep the cake tender.
• Vegetable or Canola Oil: Keeps cake moist and tender without flavor interference.
• Vanilla Extract or Vanilla Bean Paste: Elevates the flavor complexity in both cake and frosting.
• White Vinegar: Reacts with baking soda to lighten the cake’s crumb and deepen color.
• Red Gel or Liquid Food Coloring: The iconic bright red shade crucial for red velvet.
• Full-Fat Cream Cheese: The star of the frosting, adding tangy smoothness.
• Powdered Sugar: Sweetens and thickens the buttercream to pipeable perfection.
• Heavy Whipping Cream: Lightens the frosting texture, making it easier to spread and pipe.
• Seedless Raspberry or Strawberry Jam: Creates the realistic edible “blood” effect that makes this cake so memorable.
• Water and Optional Food Coloring: Used to thin the jam for spreading and intensifying color.

Variations

One of my favorite things about this Brain Cake Recipe is how easy it is to make your own. I’ve played around with flavors and colors, and honestly, the possibilities feel endless. Here are a few tweaks I love or recommend you try!

• Vegan/Dairy-Free Version: I swapped in plant-based milks and vegan butter once, and it turned out surprisingly delicious without sacrificing texture or flavor.
• Different Colors: Tried purple or green food coloring for a “mad scientist” vibe—fun for parties beyond Halloween!
• Flavor Boost: Adding a teaspoon of almond extract to the frosting gave it a lovely complementary note that everyone loved.
• Mini Brain Cakes: Making cupcakes and decorating them with piped “brain” swirls is perfect for smaller gatherings or kids’ parties.

How to Make Brain Cake Recipe

Step 1: Prepare Your Cake Layers

First things first—preheat that oven to 350°F (175°C). Prepare your cake pans by spraying with non-stick baking spray and lining with parchment paper; this step is a game-changer for easy cake removal later. Next, sift together your cake flour, cocoa powder, baking soda, and salt into a medium bowl—this ensures even distribution and no clumps. In your stand mixer or with a hand mixer, cream the butter and granulated sugar at medium-high speed until lighter and fluffy; this takes about 1-2 minutes and really helps your cake be tender. Add the eggs one at a time, mixing so everything combines beautifully.

Step 2: Combine Wet and Dry Ingredients

Now comes the fun part: mix in the buttermilk, oil, vanilla, vinegar, and red food coloring. It might look a little separated or “broken,” but don’t worry! Slowly fold in your dry ingredients in two batches on low speed, just until you can’t see streaks of flour anymore. This method makes sure your batter stays light and your cake tender. Divide the batter evenly into your pans, about 415g per pan, and pop them into the oven for about 24-28 minutes. A toothpick inserted into the centers should come out with a few moist crumbs when done.

Step 3: Cool and Carve Your Brain Shape

After baking, let your cakes cool in the pans for 10 minutes, then gently loosen the edges with a small offset spatula and flip onto wire racks to cool completely. Here’s a trick I learned: if your cakes seem too delicate or soft for carving, stash them in the freezer for 20 minutes—it firms them up and makes shaping much easier. To create that realistic brain form, stack your layers and trim about an inch off two sides to create an oval shape. Use a sharp, small knife to round off the top edges. If you’re prepping in advance, wrap each layer well and freeze them now.

Step 4: Whip Up the Cream Cheese Buttercream

Using softened butter and cream cheese, beat them together at medium speed for about 30 seconds until smooth. Stir in vanilla and salt, then add powdered sugar slowly to avoid messy sugar clouds—cover your mixer with a kitchen towel if you can! Add in heavy cream in small amounts until the frosting reaches that perfect creamy, pipe-able consistency. A splash of red food coloring turns it a pretty pink, which is what gives this cake its striking look. Cover it with plastic wrap while you work on assembly to keep it fresh.

Step 5: Assemble and Decorate Your Brain Cake

Start stacking your cake layers with big dollops of frosting in between to hold it all together. Use a little frosting on your cake board to anchor the first layer too. Once stacked, trim and smooth the cake edges as needed to perfect the shape. Apply a crumb coat—a thin layer of frosting covering the whole cake—to lock in crumbs and chill it until firm (20 min fridge or 5 min freezer). Then, load your piping bag with frosting and pipe wiggly lines all over to mimic brain folds. Don’t stress perfection here; the raspberry jam you spread later covers imperfections. Chill again to firm up.

Step 6: Add the Edible “Blood” Glaze

Whisk seedless raspberry jam with water and optionally extra red food coloring to make a smooth, vibrant red glaze. Use a pastry brush to coat your piped frosting thoroughly—the jam seeps into every nook, creating the ooey-gooey bloody effect that makes this brain cake literally pop. Don’t hold back around the base for an extra gruesome vibe. Chill once more to set the glaze, then invite everyone over to admire (and devour) your masterpiece!

How to Serve Brain Cake Recipe

Garnishes

I usually keep garnishes simple so the brain cake is the star—sometimes a few fresh raspberries or edible rose petals scattered around the base add a little elegance. If you’re feeling adventurous, you can add some black fondant spiders or edible glitter for spooky sparkle.

Side Dishes

This cake pairs wonderfully with lightly whipped cream or a dollop of vanilla ice cream. For drinks, I like to serve with rich hot chocolate or a fruity punch to complement the tangy cream cheese frosting.

Creative Ways to Present

For Halloween parties, I’ve presented the brain cake on a platter surrounded by dry ice for a spooky fog effect—absolutely loved by guests! Another time, I placed it on a vintage silver stand with dark red tablecloth and flickering candles for an eerie-chic vibe.

Make Ahead and Storage

Storing Leftovers

I wrap leftover slices tightly in plastic wrap or store in an airtight container in the fridge. Covering exposed parts with a bit of leftover frosting keeps the cake moist and fresh. Leftovers tend to stay delicious for up to a week when refrigerated.

Freezing

I’ve had great success freezing both unfrosted cake layers and fully frosted brain cake. Just wrap layers in plastic wrap and foil before freezing. For best taste and texture, thaw in the fridge overnight before decorating or serving.

Reheating

Reheating is usually not necessary for this cake, but if you want to warm a slice, I recommend a quick 10-15 second zap in the microwave at low power. This softens the cream cheese frosting without melting it completely.
