The good excuse to make them: Mother's Day. In a nutshell, you make brownie batter, cookie batter. Pour brownie batter, plop cookie batter. Bake for 35-40 min at 350. Top with ganache. Crazy enough, I could have actually done with about 1/2 the ganache topping, or regular chocolate frosting. I think I'd appreciate the stuff underneath more without all that topping.
