Texas Sheet Cake Recipe

These Texas Brownies – also known as Texas Sheet Cake –  are my favorite brownies in the history of all things chocolate and ooey and gooey. I love how you can bake them and put the frosting on immediately instead of waiting for them to cool to do the final steps. Here’s the run-down of how they’re made:

Ingredients you’ll need for this chocolate sheet cake recipe

For the BROWNIES:

  • 2 cups flour
  • 2 cups sugar
  • 1 cup butter
  • 1 cup strong brewed coffee or water
  • 1/4 cup cocoa
  • 1/2 cup buttermilk**(If you don’t have buttermilk, pour 1/2 Tablespoon lemon juice into a measuring cup and add enough milk to equal 1/2 cup.)
  • 2 eggs
  • 1 tsp. baking soda
  • 1 tsp. vanilla

For the FROSTING:

  • 1/2 cup butter
  • 2 Tablespoons cocoa
  • 1/4 cup milk
  • 3 1/2 cups powdered sugar
  • 1 tsp. vanilla

Step 5: Pour batter into pan. ( The recipe calls for it to be poured into a jelly roll pan (17 1/2 x 11 inches), but this time, I used 2 disposable cookie sheet pans I purchased from the Dollar Store. That way I didn’t need to worry about making sure I got my pans back! It worked like a charm.)

Step 6: While the brownies are baking, prepare the frosting.

To make the frosting, in a saucepan, combine the butter, cocoa, and milk. Heat to boiling, stirring. Mix in the powdered sugar and vanilla until frosting is smooth. (I use my electric mixer to make sure it is really smooth.)

Step 7 *This is key* ~ Once the brownies are finished baking, pour the warm frosting over the brownies and spread out quickly and add sprinkles if you’d like. The frosting sets quite fast, so you don’t want to dilly dally on this step!
