Melt Butter
Place the butter cubes in a small saucepan over low heat and melt, stirring occasionally until fully liquid.

In a large mixing bowl, whisk together the melted butter, granulated sugar, brown sugar, and cocoa powder until smooth and glossy.

Cool Brownies Slightly
Allow the baked brownies to cool in the pan on a cooling rack for about 15 minutes so they set but are still warm enough for the ganache.

Time: PT7M
Set and Slice
