Moist and cake-like, these brownies are sometimes called Texas sheet cake. Because the bars are baked in a 15x10-inch pan, you'll have enough to feed a crowd.

Beat with an electric mixer on medium speed until combined. Add the eggs, buttermilk, and vanilla. Beat for 1 minute (batter will be thin). Pour batter into prepared baking pan.

Instructions Checklist
  • Bake about 25 minutes for the 15x10x1-inch pan, about 35 minutes for the 13x9x2-inch pan, or until a wooden toothpick inserted in the center comes out clean.

Tips

To make 1 cup sour milk, place 1 tablespoon lemon juice or vinegar in a glass measuring cup. Add enough milk to make 1 cup total liquid; stir. Let mixture stand for 5 minutes before using. Use 1/2 cup sour milk in the brownies and 3 tablespoons sour milk in the frosting. Discard remaining sour milk. Or reconstitute dry buttermilk by following the directions on the powdered buttermilk container.

I have made this recipe numerous times, and are a huge hit every time!! I will offer a few suggestions. Best to bake them in a 13x9x2 pan. Be sure to spread frosting over cake-like brownies when they are fresh out of the oven. I typically put the frosting in a glass measuring cup, and microwave at least a minute to get it extremely hot, then pour over brownies. Spreads easily when thin and warm. They are absolutely delicious! I promise!!

Definitely cakey but oh so good. Added more cocoa to both the brownie and frosting, toasted the pecans, and added chocolate chips to the batter . Was craving chocolate and oh how well this fit the bill. I have convinced myself that if I go to the trouble of baking that removes the calories. Enjoy.
