Ingredients You’ll Need

The beauty of this Brownie Cake lies in its straightforward ingredients, each chosen to build layers of flavor and texture that complement each other perfectly. From the cocoa powder that deepens the chocolate taste to the buttermilk that keeps the cake incredibly moist, every item plays its part without requiring any fancy shopping trips.

• All-purpose flour: The foundation for both the cake and brownie layers, providing structure and tenderness.
• Unsweetened cocoa powder: Adds rich chocolate intensity without any sweetness, balancing the sugar.
• Baking soda and baking powder: These leavening agents ensure your cake rises beautifully and stays light.
• Salt: Enhances all the chocolate’s flavors and keeps the sweetness in check.
• White granulated sugar: Sweetens both the cake and the brownie batter for the perfect balance.
• Large eggs: Bring structure and richness; room temperature eggs help with smooth mixing.
• Oil (canola or vegetable): Keeps the cake moist and tender without a heavy texture.
• Pure vanilla extract: Adds warm, aromatic depth to the chocolate layers and frosting.
• Buttermilk: Adds tang and moisture while tenderizing the crumb of the cake.
• Hot water: Intensifies the cocoa flavor and helps dissolve the dry ingredients smoothly.
• Unsalted butter (melted): Used in the brownie batter to create that fudgy texture every brownie lover dreams of.
• Cornstarch: Stops the brownie layer from becoming too cakey, maintaining its gooey center.
• Semi-sweet chocolate chips: Melt into pockets of melted chocolate that take the Brownie Cake over the top.
• Cream cheese: The star of the frosting, giving it a subtle tang and luscious creaminess.
• Powdered sugar: Sweetens and thickens the frosting, making it perfect for spreading.

How to Make Brownie Cake

Step 1: Prepare the Chocolate Cake Batter

Start by preheating your oven to 350°F and preparing three 8-inch cake pans, spraying them and lining with parchment circles to ensure easy release later. In a large bowl, whisk together all-purpose flour, cocoa powder, baking soda, baking powder, salt, and sugar. Separately, whip up your wet ingredients: eggs, oil, vanilla, and buttermilk, then gradually add steaming hot water to the mix for that signature deep chocolate flavor. Combine wet and dry ingredients gently into a smooth but not overmixed batter, then divide evenly among the pans. This creates a soft, moist base that’s naturally delicious before adding the brownie surprise.

Step 2: Make the Brownie Batter

While your cake batter rests, move onto the luscious brownie batter. Mix the dry ingredients first—flour, cocoa powder, cornstarch, and salt—and set aside. Beat sugar and eggs at high speed until thick and light, about 5 minutes; this is key for the right fudgy texture. Slowly incorporate vanilla, oil, and melted butter before folding in the dry mix just until combined. Lastly, hand-stir chocolate chips through the batter to add melty bursts of chocolate in every bite. Using a cookie scoop, dollop the brownie batter evenly on top of each cake layer. Swirl lightly with a knife, making sure to create those irresistible brownie pockets baked right into the cake.

Step 3: Bake and Cool

Bake the cake and brownie layers for about 30 to 35 minutes until a toothpick comes out with moist crumbs. Avoid overbaking as the brownie swirls need to stay gooey, not dry. Let the cakes sit for 10 minutes in their pans before transferring to a wire rack to cool completely. Cooling is crucial to keep the frosting luscious and prevent melting during assembly.

Step 4: Prepare the Chocolate Cream Cheese Frosting

For the frosting, start by sifting powdered sugar and cocoa powder together to avoid lumps. Then beat cream cheese and butter on high speed until light and fluffy, creating a perfect creamy base. Add the powdered sugar in two batches to keep texture smooth and mix in vanilla extract for that extra comforting flavor. Beat everything until the frosting is silky with a slightly lighter chocolate hue, ready to be spread generously between and over your cake layers.

Step 5: Assemble Your Brownie Cake

Use a serrated knife to cut off any domed tops from your cakes so the layers stack evenly. Spread one cup of frosting on the first layer, then a second cake layer with more frosting. Place the third layer upside down to showcase the bottom’s smoothness, then apply a thin crumb coat of frosting all around the cake. Pop it in the freezer for 15 minutes to let the crumb coat set, making it easier to apply the final smooth layer. Finish with a generous coating of frosting and get ready to wow everyone with this show-stopping Brownie Cake.

How to Serve Brownie Cake

Garnishes

While this Brownie Cake looks stunning on its own, adding fresh garnishes elevates both the look and flavor. Think glossy chocolate shavings, a sprinkle of crushed nuts, or a handful of fresh berries to add a burst of color and freshness. You absolutely can’t go wrong with a drizzle of melted chocolate or even a light dusting of cocoa powder for a rustic, charming finish.

Side Dishes

Pairing your Brownie Cake with simple sides can make the experience even more memorable. A scoop of vanilla bean ice cream or a dollop of whipped cream balances the rich chocolate perfectly. Fresh fruit like strawberries, raspberries, or sliced bananas add natural sweetness and a touch of acidity that cuts through the decadence. For a grown-up twist, a glass of cold milk, coffee, or a berry-infused dessert wine works wonders.

Creative Ways to Present

Presentation is part of the fun when serving a Brownie Cake. Slice large wedges to showcase the swirling brownie batter through each piece. You could also create individual portions by turning slices into mini trifles with layers of frosting and berries in clear glasses. Another creative idea is to pipe rosettes of frosting with a patterned tip on top, or use edible gold dust for a glamorous finish that impresses at any celebration.

Make Ahead and Storage

Storing Leftovers

Once frosted, your Brownie Cake can be stored at room temperature in an airtight container for up to two days, though it’s best kept in the fridge to preserve the cream cheese frosting and freshness. Make sure to cover it well to prevent it from drying out or absorbing other fridge odors. This cake actually tastes great the next day as the flavors meld even more!

Freezing

If you want to save some cake for later, this Brownie Cake freezes beautifully. Wrap the whole cake tightly in plastic wrap and then in aluminum foil to protect it from freezer burn. Freeze for up to three months. When ready to enjoy, thaw overnight in the fridge to keep the texture just right.

Reheating

Since this is a rich, frosted cake, it’s best enjoyed cold or at room temperature rather than reheated. If you do want to warm a slice slightly, place it in the microwave for 10 to 15 seconds to soften the brownie swirls just a bit—but be cautious to avoid melting the frosting. A little warmth can bring out the fudgy goodness in the brownie bits delightfully.

FAQs

What makes this recipe a Brownie Cake?

This recipe uniquely combines traditional chocolate cake batter with dollops of fudgy brownie batter swirled right in, creating a textural duality that’s both fluffy and dense in every bite. Plus, the rich cream cheese frosting adds another layer that’s hard to resist.

Can I use regular milk instead of buttermilk?

You can substitute regular milk with a tablespoon of lemon juice or vinegar added to a cup of milk as a quick buttermilk replacement. This acidity helps tenderize the cake and enhance the chocolate flavor.

Why swirl the brownie batter into the cake instead of fully mixing it?

Swirling creates pockets of rich, fudgy brownie inside the lighter cake, giving you delightful texture contrasts. Mixing it fully would result in a uniform batter, losing the special brownie effect.

How do I prevent the cake from drying out?

Use room temperature eggs and buttermilk as directed, and avoid overbaking. Keeping the cake covered or wrapped well after cooling helps maintain moisture. The oil in the batter also contributes to a moist crumb.

Is this Brownie Cake suitable for special occasions?

Absolutely! Its impressive presentation, decadent textures, and crowd-pleasing flavors make it a fantastic choice for birthdays, anniversaries, or holiday celebrations. It’s sure to impress guests and bring smiles all around.
