A simple recipe starting with a box of cake mix makes for a pretty delicious little brownie. This can be GF too if you buy the appropriate cake mix. I'm not sure where I dug this one up!
1 box chocolate cake mix
1/4 cup vegetable oil
1/3 cup milk
10 oz chocolate chips
Preheat your oven to 350.
Spray an 8x8 pan.
Mix all ingredients except the chocolate (it will become smooth pretty easily).
Stir in chocolate chips.
Spread the batter into the 8x8 pan (its pretty thick!).
Bake for about 20 minutes. (Don't overcook! Gooey = love).
Allow them to cool completely before cutting.
