Looking for an over-the-top dessert that doesn’t take all day to make? Our Black and White Brownies strike just the right balance of delicious and just fancy enough (but not too fancy) to serve for any type of gathering, from a wedding shower, to a family dinner.

Black and White Brownies

Nothing tops a good brownie in my book and this homemade brownie with buttercream and a chocolate glaze is going to be your new favorite dessert! It takes less than 10 minutes to mix the brownie together, and while the brownie is baking (or cooling) make the buttercream. I like to make this dessert the day before serving, then store in the fridge until I’m ready to serve.

The buttercream takes a minute to whip up in a stand mixer. Beat the butter, add powdered sugar, cream or half and half and a bit of vanilla. When the brownies are cooled, frost the brownies with the buttercream and place in the fridge for 10 minutes to allow the buttercream to cool. Then top with a chocolate glaze.

I pop it back into the fridge again to let it set up, then cut. Usually 30-60 minutes in the fridge after topping with the glaze is enough time to allow a nice clean cut. I recommend cutting the brownies with a sharp knife and wiping the knife after each cut to keep a clean edge.

For easy cleanup and lifting out of the 9×13 pan, I use a parchment liner in the pan. I’ve also used foil to line the pan and that works as well! These brownies taste as good as they look. Maybe better. If that is possible!

For brownie layer:
