Frosting is the literal icing on top. That saying exists for good reason.

It is the frosting that really makes or breaks a cake. It makes all of the difference.

Any old cake can be made extraordinary with a perfect frosting. This fudgy goodness has brownie mix right inside.

It makes for a super delicious topping for a variety of cakes. We put it on a butter cake this time.

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.

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!

You had me at brownie, then you really had me at frosting. I would sit and eat this with a spoon. I think it needs me.
