Notes
- Chill the brownies before cutting. These taste extra delicious served cold straight out of the fridge!
- Bake in a 13 x 9 baking dish. You’ll have plenty of thick, moist brownies to go around.
- How to store brownies: Stored in the fridge, rainbow chip brownies stay good for about 1 week. For longer storage, you can freeze them.
