Brownie Batter Frosting

Thanks for sharing!

Brownie batter frosting has all the wonderful qualities of buttercream with brownie mix whipped right in. This chocolate goodness is just begging to be put on your next cake.

What you put on your cake is every bit as important as the cake itself, maybe even more so. Luckily the rich and chocolaty brownie batter buttercream is almost always a good choice.

It is fabulous on a good butter cake and wonderful on top of banana cake. Of course it would be lovely on a chocolate cake as well.

Try it on a batch of cupcakes or sandwich it between cookies. Pretty much any baked good is a great excuse to make a batch of fluffy brownie batter buttercream.

MiMi originally shared this recipe in 2015. Back in the days when I was a frosting aficionado and not yet the self appointed queen of frosting!

MiMi has always love dense fudgy chocolate frosting like the almost flaky chocolate frosting on her official birthday cake, her grandma’s french butter cake with fudge frosting. This is similar to that in a lot of ways, but with buttercream flexibility.

What MiMi had to say about this recipe is 2015

I had some bananas that were getting a bit soft. My first thought was banana bread but then I decided I needed a dessert.

Carlee has made Di’s Banana Cake several times so it must be a hit. I decided to make that and change it a little by trying a new frosting.

I had just created a Brownie Batter Ice Cream recipe so I had some brownie mix left. What a great way to top banana cake.

I like a thick fudgy frosting so that is what I made. It is thick, rich and yummy.

How to Heat-Treat Brownie Mix

We have always known there was some risk involved in eating raw cookie dough and cake batter from the raw eggs. But in recent years we have become more aware of the bacteria that can be present in raw flour and cake mixes.

However, you can mitigate that risk by “heat-treating” the mix. Luckily, it’s super simple and takes just a minute or two. Here’s how…

• Dump the mix into a glass microwave safe bowl.
• Microwave on high for about 1 to 1 ½ minutes, stirring every 20 seconds.
• The brownie mix will be warm (160F) and any bacteria that were present will be gone!
• Let the mix cool completely before adding to the recipe.

More Great Chocolate Frosting Recipes:

If you are looking for a slightly fluffier frosting that maintains the rich chocolate flavor, try making chocolate sweetened condensed milk buttercream. It is perfect for spreading over cakes or piping on cupcakes.

Or whip up white chocolate buttercream. It is super fluffy and has a great white chocolate flavor but is still super versatile.

For another great spreading frosting, try shiny fudge frosting. It works great for layer or sheet cakes, but is not meant to be piped. The sheen and flavor on that one is amazing!
