Brownies With Reese Cups. The ultimate one bowl reese's brownie recipe. Put batter in paper cupcake liners 3/4 full.

Bake until the top is shiny and the center has puffed up but is still slightly jiggly (a toothpick inserted will not come out clean), about 40 to 45 minutes. Mix the batter with a rubber spatula to make sure it is mixed. Remove from oven and let cool.
