This showstopping White Layer Cake with Fudgy Brownie is two layers of brownies, two layers of white cake, frosted with a beautiful buttercream rosette. I have the perfect decorator’s buttercream you can use to create a pretty design.

White Layer Cake with Brownie

If you look at the cake, it’s all about the lovely rose design using my decorator’s frosting. No one would know that it is made with box mixes of a cake and brownies! Yes, you could simply frost the cake with any kind of frosting, but don’t give up on the rosettes just yet. I have a full tutorial on how to make a rose cake.

Cake Ingredients

Brownies: Grab a box of brownie mix (I like the fudge variety) to make the brownie layers.

Cake: All you need is a box of white cake mix that perfectly complements the brownies.

How to Frost with Decorator’s Buttercream

If you are frosting your cake with decorator’s buttercream, as I did, try frosting your cake chilled. This rose cake design works best with a crumb coat underneath, but because it has SO MUCH FROSTING, doing a thin crumb coat is best. When you apply the crumb coat to a chilled cake, the crumbs tend to behave a little better.

Can I Use Different Frosting?

Sure! This cake is delicious even without any fancy designs. If you do not use decorator’s buttercream, try my American Buttercream, some easy frosting options, chocolate buttercream, or even store-bought frosting.

Can I Make this Cake Without Box Mixes?

Definitely! If you are feeling up to it, this cake can definitely be made homemade. I recommend using my homemade brownie mix, along with my white cake recipe.

Can I Make this Cake in a Different Pan?

Sure. If you would like to make this white layered cake with fudgy brownie in a 9×13-inch baking dish, I recommend using the boxed mixes. I have not tested my homemade recipes in that size of a pan.

How to Store White Layer Cake with Fudgy Brownies

To store the cake after frosting, cover it with a cake dome or a large bowl. It will last at room temperature for 4-5 days. If you have cut the cake, place plastic wrap against the cut side to keep the cake from drying out.

Ingredients

Instructions

  • Preheat the oven to 350°F. Spray two 8-inch round cake pans with nonstick cooking spray and line with parchment paper.
  • Prepare the brownie batter, according to package instructions.
  • Evenly divide the batter between the two prepared cake pans.
  • Bake the brownies for just 10 minutes. (They will not be fully cooked.) While the brownies are baking, prepare the white cake batter, following the package instructions.
  • After 10 minutes, carefully remove the partially baked brownies.
  • Equally divide the white cake batter between the two pans, carefully pouring it over the brownies.
  • Return the cake pans to the oven and bake for another 16-22 minutes, or until an inserted toothpick is removed with some crumbs, but no wet batter. The cake should dome slightly and start to pull away from the edges of the pan.
  • Let the cake cool before adding decorator's buttercream.
