With Theo Chocolate's Madagascar bar cut into bits: http://theochocolate.com/. I mix the pieces into my regular brownies and it makes them even richer and darker. My brownie recipe is gluten-free and works differently than other recipes, even though it tastes just as good. I'll share it if you'd like, but it's not a usual brownie recipe.

I have to confess, I love the recipe on the back of the Ghirardelli Sweet Ground Chocolate and Cocoa can.

Love this recipe, with or without the peppermint patties: http://www.pbs.org/everydayfood/baking/recipes/mint_chocolate_brownies.html
