Something I did last night, not sure if its a hack or just a twist, when making brownies, whether from a box or homemade, instead of plain water, sub in coffee.
If we have some leftover coffee from the morn Ill use that or of not we have some instant coffee packs, Folgers and Cafe Bustello, Ill use one of those to mix into the brownie batter. Chocolate and coffee play very well together
