brownie-in-a-mug recipe. I like this one better because it requires butter as opposed to oil (makes it less likely to burn in the microwave)

Microwave Brownie in a Mug (single serving) 2 Tbs vegetable oil 2 Tbs water Few drops vanilla extract A dash salt A pinch instant coffee powder (optional) 3 Tbs granulated sugar 2 Tbs unsweetened cocoa powder 2 Tbs all purpose flour (cocoa brownies oil)
