Mexican Chocolate Sheet Cake

A super easy no-fail chocolate sheet cake that is moist, rich made with a hint of Mexican inspired spices and gluten-Free! Topped with a fluffy layer of chocolate buttercream frosting. This cake will be a favourite for years to come guaranteed!

Who doesn’t love a good chocolate cake? Let alone an easy to make a chocolate cake like this one. This chocolate cake recipe makes a cake that is light, full of chocolate flavour and is never dry.

My son makes this recipe all the time as a two-layer round cake but I prefer it sheet cake style because it is just one less step to deal with. No stacking needed! Just make the batter, pour it in the pan and bake! Add frosting and decorate how you like and you are good to go!

The recipe uses a combination of cinnamon, nutmeg and a hint of cayenne pepper to give it a uniquely Mexican inspired flavour. Don’t panic over the cayenne pepper. It doesn’t make the cake spicy at all. Cayenne pepper actually works to deepen the chocolate flavour of the cake and who doesn’t want that?

What makes this Mexican chocolate sheet cake recipe great?

  • It is gluten-free but can be made with all-purpose flour as well
  • No fancy cake assembly required. One 9″ X 13″ cake pan is all you need!
  • Easy to transport to parties and serve
  • Chocolate -y and rich but not overly so
  • Light and creamy chocolate frosting that is easy to make
  • The cake is made in one bowl and another for the frosting – not a crazy amount of dishes
  • Spices are subtle but give the cake a uniquely rich and super tasty flavour
  • This cake can be made ahead of time and iced the next day or frozen for another time

Some of my other favourite chocolate recipes that are gluten-free are:

How to make this chocolate sheet cake

What is Gluten-Free 1:1 Flour?

When a recipe calls for all-purpose flour you can easily swap the flour out for gluten-free 1:1 flour in many recipes. Gluten-free 1:1 flour is a combination of gluten-free flours and includes xanthan gum in the mix allowing you to easily make any recipe gluten-free. One cup of all-purpose flour equals 1 cup of gluten-free 1:1 flour.

Why does this chocolate cake use vegetable oil?

Cakes that use vegetable oil in them tend to stay moister and fresher tasting longer than those that rely on butter. Vegetable oil has a very mild taste so it blends easily into cake batter without adding a flavour of its own.

Can you freeze this sheet cake recipe?

Yes this cake freezes very well for up to 2 months. Once completely cooled freeze the cake on a baking sheet lined with waxed paper. Then when frozen wrap tightly in plastic wrap and mark with a date so you now when it was placed in the freezer. Defrost in the fridge overnight.

How long will this Chocolate cake stay fresh?

This cake will stay moist and fresh for up to 3 days on the counter so long as it is tightly wrapped or covered. Or you can freeze the cake for up to 2 months.

How many servings in a 9″ X 13″ sheet cake?

A 9″ X 13″ sheet cake will typically serve 15 to 20 pieces of about 2″ X 3″. My family usually just grabs a knife and eyeballs it with my husband taking a solid 8th of the cake, me a standard 2″ X 3″ size and so forth. So it really depends on what size of chocolate cake craving you are having! Your piece, your choice in my house!

What kind of frosting is best?

That really depends on personal preference. I love the frosting I made for this cake because it is light and fluffy with the right about of chocolate flavour that isn’t too overpowering. Others may prefer a vanilla icing, ganache or fudge icing. Once the cake is made really any frosting and creative decorating will do but you have to give my frosting a try… it is scrumptious!
