Texas Sheet Cake is an instant crowd-pleaser. It’s a large-format cake made of a thin layer of rich chocolate cake covered in a poured chocolate icing while hot from the oven and finished with crunchy pecans. This version of Texas Sheet Cake is made even easier with the help of Betty Crocker™ Cake Mix. The addition of sour cream and coffee to the batter makes the cake extra moist and flavorful.

How to Make Easy Texas Sheet Cake

Here are our best tips for making Easy Texas Sheet Cake. See the full recipe for complete instructions.

1. Make and Bake the Cake

Spread the batter into the baking pan making sure to get it into the corners. Take care to spread evenly so the icing can coat the top of the cake evenly. The cake will bake quickly, be sure not to over bake it or it will dry out.

2. Make the Frosting

The frosting in this recipe starts on the stovetop and is poured directly onto the hot cake. It cools into a satiny finish with a slight crackle as you cut into it.

3. Add Pecans

Add the pecans immediately after frosting the cake so they nestle into the frosting as it sets up and cools. If you don’t like nuts, use sprinkles for a fun variation or leave the icing unadorned for a simple finish.
