Instructions
Brownie buttercream frosting - Use ingredients above - It is best to sift the cocoa powder and powdered sugar together to remove any lumps first. This will help ensure a smooth frosting. In a large mixing bowl, use an electric mixer or a stand mixer with your paddle attachment to cream the softened butter until it becomes smooth and creamy for about 2 minutes.
Add all other ingredients and beat on low speed initially for 30 seconds, then increase to high for another 60 seconds. Scrape down the sides of the bowl to ensure even mixing.
If you think it is too thick gradually add up to another 1/4 c powdered sugar to thicken or 1 tbsp of cream until it is the texture you want.
Use immediately or if you want it cold or to use later spoon into a piping bag or sealed container and store in the fridge for up to 1 week. Allow to soften on countertop out of fridge before piping out of bag.
Brownie Ganache - 1/3 cup chopped chocolate or chips + 1/4 tsp vanilla + 6 tbsp whipping cream + pinch of salt
You can heat the cream until hot in a double boiler and add the chopped chocolate pieces or chips. Stir until you have a smooth ganache with no remaining chocolate chips. (this could also be done by melting chocolate chips in microwave in 30 second increments stirring in between until smooth)
Place brownies on a wire rack and top with chocolate ganache. Leave for an hour and a half to harden. Best stored in the refrigerator for topping to not melt
