This Texas sheet cake is a true classic and one I remember my mom making growing up. If you’ve never had this cake before, you need to make it ASAP. It makes a lot, so make it when you have guests over or for your next potluck or party. If not you’ll be regretting eating the whole pan. ;)


The frosting may be the BEST part about the cake. It thickens as it cools and turns into a creamy fudge layer on top of the cake. It seriously is so good! I may or may save a little frosting in the pan just for me.

This recipe is very similar to your classic recipe, however I like to add sour cream. I find it makes the cake a little softer and less dense.  To make this cake you just need these staple ingredients:

  • butter
  • flour
  • sugar
  • cocoa powder
  • sour cream
  • eggs
  • baking soda
  • vanilla (I always add a little more for good measure)

I do have to warn you that this isn’t your typical mix everything in a bowl type of cake. There is a little more work involved on the stove, but I promise you, it will be worth it. Once the cake is done pour the frosting immediately over the top of it. It helps soak in and keep it moist. The frosting also thickens pretty fast, so make sure to spread it out quickly (however don’t press too hard) with a rubber spatula, so you don’t break the cake.

Sometimes I’ll add chopped nuts (usually to only one side, since I’m the only one likes them) and then sprinkles for the kids.

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon table salt
  • 1 cup salted butter
  • 1 cup water
  • 1/4 cup unsweetened cocoa powder
  • 2/3 cup sour cream
  • 2 large eggs whisked
  • 1 Tablespoon pure vanilla extract


  • 1/2 cup salted butter
  • 1/4 cup unsweetened cocoa powder
  • 1/3 cup milk
  • 1 teaspoon vanilla extract
  • 3 cups sifted powdered sugar


  1. Preheat the oven to 350°F. Grease or line a half sheet pan (18 x 13 inches) with foil and set aside.
  2. Combine flour, sugar, baking soda, and salt in a large mixing bowl. Set aside.
  3. Heat the butter, water and cocoa in a medium saucepan over medium heat. Bring to a light boil and then remove from heat and add to flour mixture and stir until combined.
  4. Stir in the sour cream, vanilla, and eggs. Pour mixture into prepared pan.
  5. Bake for 18-20 minutes, or until a toothpick comes clean.
  6. While the cake is cooking start the icing (I usually start after about 10 minutes in). Melt the butter in a medium saucepan over low heat. Stir in cocoa powder. Once the mixture has melted and come to a light simmer, remove from heat and slowly stir in milk, vanilla, and a pinch of salt. Then slowly stir in powdered sugar.
  7. Evenly pour the icing over the cake, immediately when it comes out of the oven. Immediately spread out evenly with a rubber spatula.
  8. Allow to cool and then cut into squares.
