This Mint Chocolate Texas Sheet Cake is a double-batch of chocolate cake, with chocolate chips and mint extract mixed into the batter. The flavorful cake is topped with a positively decadent fudge ganache icing, and more chocolate chips! Every bite is filled with minty, chocolate-y deliciousness!

Helpful Kitchen Tools

Instructions

To Prep: Preheat oven to 350 degrees F and mist a 9×13″ baking dish with non-stick cooking spray.

  1. Mix together the cake ingredients until well combined and pour the cake batter into the prepared pan. Bake for 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Remove from oven and allow to cool.
  2. Add chocolate chips to a heat-safe or microwave-safe bowl. Warm the heavy whipping cream in a small saucepan over medium heat until steaming (but not boiling) and then pour over the chocolate chips. Allow to sit for a minute, then stir until the mixture is melted and smooth.
  3. Pour the ganache on top of the cooled cake and spread evenly. Sprinkle the mini chocolate chips on top and allow the frosting to set.

Prep Tips

  • If you don’t have mint extract you can substitute with peppermint extract (see notes on this in the FAQ section below).
  • Jazz up the cake and add more minty flavor by sprinkling mint baking chips or chopped Andes mints on top! You could also try mixing white chocolate chips into the batter instead of semi-sweet for more creaminess.
  • To mix the cake, we used a stand mixer with paddle attachment. However, a hand-held mixer and large mixing bowl will also do the trick.

Frequently Asked Questions

Are Mint Extract and Peppermint Extract the Same Thing?

Mint extract is a combination of spearmint and peppermint essential oils, while peppermint extract is just peppermint alone. Mint extract is a more subtle flavor, with a hint of sweetness. If you need to substitute with peppermint extract, I recommend halving the amount so the peppermint is not overpowering.

Does This Cake Need to be Refrigerated?

Generally, I don’t refrigerate cakes unless they are made with cream cheese frosting. This chocolate mint sheet cake is made with a chocolate ganache frosting, which can be stored at room temperature for up to 2-3 days. If you think you might need to store it a little longer, then I recommend refrigerating, as it will last about a week in the refrigerator. Either way, you’ll want to protect the cake with plastic wrap or a lid (if your baking dish has one).
