Brownie Birthday Cake Fudge Layers (Print)

Layers of chewy brownie, chocolate fudge frosting, and sprinkles. Ideal for festive celebrations and chocolate fans.

# What You'll Need:

→ Brownie Layers

01 - 1¼ cup unsalted butter, melted
02 - 2½ cups light brown sugar, packed
03 - 4 large eggs, at room temperature
04 - 2 teaspoons vanilla extract
05 - 1½ cups cocoa powder
06 - ¾ cup all-purpose flour, spooned and leveled
07 - ¾ teaspoon salt

→ Fudge Frosting

08 - 5 tablespoons unsalted butter, at room temperature
09 - ½ cup + 2 tablespoons cocoa powder
10 - 2½ cups powdered sugar
11 - ⅓ cup milk
12 - 1 teaspoon vanilla extract
13 - Rainbow sprinkles, optional

# How to Make It:

01 - Preheat the oven to 350°F. Spray two 8-inch round cake pans with non-stick spray and line the bottom with parchment paper. Set aside.
02 - In a large microwave-safe bowl, melt the butter. Add in the brown sugar and whisk until fully combined. Add in the eggs, one at a time, whisking in between. Then add the vanilla extract.
03 - Mix in the cocoa powder, flour, and salt until just combined and no streaks remain. The batter will be thick.
04 - Pour the batter equally into the two prepared pans. Bake in the oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the brownies to cool in the pan for about 10 minutes, run a sharp knife around the edges to release the brownies, and then flip them onto a wire cooling rack to cool completely.
05 - Use an electric mixer to beat the butter until smooth. Add in the cocoa powder, powdered sugar, milk, and vanilla, mixing on low until combined. Increase speed to medium and beat for another minute until smooth. If the frosting is too thick, add 1 teaspoon of milk at a time until you reach the desired consistency.
06 - Once the brownie layers have cooled completely, place one layer onto a cake plate and top it with half the frosting (and sprinkles if using). Add the second brownie layer on top, followed by the rest of the frosting and sprinkles.

# Additional Notes:

01 - Let the brownie layers cool completely before assembling, otherwise, the fudge frosting might melt right off.
02 - Ensure all ingredients, especially eggs, are at room temperature before starting.
03 - Measure flour correctly to prevent the brownie layers from becoming dry or crumbly.
