Expert Tips:

  • Cinnamon: This is a common addition to this cake and complements the flavoring nicely! Just add about a teaspoon of cinnamon to your dry ingredients and also a bit to your icing if desired.
  • Pecans: Try adding some chopped up pecans to the icing if you’re feeling extra Texan that day.
  • Pour icing while cake is warm: this is crucial to ensure that the icing soaks into the cake nicely. The end result will be a rich, fudgy cake texture.

FAQS: Texas Sheet Cake:

Why is it called a Texas Sheet Cake?

The origins of the name of the cake are unknown, it’s possible the first appearance was in the state of Texas, or it could be simply due to the size of the cake itself. Either way, it’s a popular cake recipe that will serve a lot of people.

How many people will a Texas Sheet Cake serve?

This cake will comfortably feed 24. It really depends on how you slice the cake. It might seem like a lot of cake, but the jelly roll baking sheets are thin, so the end result is a thin cake, with a thin layer of fudge icing.

Can I make this recipe ahead of time? Can I freeze this cake?

This cake can be made completely and stored covered at room temperature for up to 5 days. The icing is meant to soak into the cake, it doesn’t get soggy as it sits.
If you’re wanting to freeze this cake, you can freeze the cake after it has been made and iced. Leave the cake in the baking sheet, let it cool completely. Then cover with plastic wrap, then a coating of foil. This can be frozen for up to a month. To use, remove from the freezer, unwrap, then let it thaw to room temperature.
