BUTTERMILK SHEET CAKE BROWNIES ~ BLOG 365.156

My aunt and grandmother would’ve called this recipe a Texas sheet cake. But we cut them into small squares and call them brownies around here.

You can make these in a 15×10 inch pan for a brownie like size or put it into a 9×13 pan and call it cake. Either way you’ll have a moist tender cake with a rich, thick fudgy chocolate frosting.
