What is a Mexican chocolate cake?

What makes a chocolate cake Mexican? No, it’s not a chocolate tres leches cake (although that cake will knock your socks off so you should definitely try it). It’s a traditional chocolate cake with added cinnamon.

The first time I had these flavors together was in a coffee shop in a Mexican hot chocolate drink. Some are spicier than others, and this cake is on the mild side. For more flavor, I added ¼ teaspoon cayenne pepper. You can add more if you’d like more of a kick, but cayenne pepper is strong so go slow adding it.

How do you make a homemade chocolate cake?

Here are some hints:

  • Whisk the dry ingredients first, then set aside.
  • Stir the wet ingredients (all but the coffee) together. We like to use a stand or hand mixer to make sure everything gets combined well.
  • Use buttermilk. We recommend buying buttermilk from the store, but if you can’t get to the store, make your own buttermilk by adding 1 teaspoon of white vinegar to a cup of milk. Allow it to sit for 5 minutes, then use the homemade buttermilk in the recipe.
  • Mix the dry into the wet.
  • Add the coffee.

**Pro Tip: “Do I have to add coffee?” If you are 100% against coffee, you can use hot water instead. But coffee makes chocolate cake have a more intense flavor so we highly recommend using coffee.**

Cinnamon Buttercream

To make your buttercream recipe REALLY stand out, here are the best ingredients to use.

  1. Powdered sugar. Using granulated sugar will make your frosting grainy, or not very smooth in texture.
  2. Salted Butter. While it’s up to preference, using butter in your buttercream frosting will make your frosting more flavorful, and less sickeningly sweet. If you don’t want to use all butter, you can use shortening. Salted butter is important because it enhances the flavor even more.
  3. Saigon cinnamon. We use this cinnamon in our best cinnamon roll recipe ever. If you’ve never tried it, do it!
  4. Whole milk or heavy cream. While substitutions like fat-free milk or almond milk can be used, whole milk or heavy cream is the best for your buttercream!
  5. Vanilla. A little vanilla goes a long way – but you’ll love what it adds to the flavor of your frosting!

Use a stand mixer or high powered hand mixer to mix the buttercream. It will be fluffiest that way.

How do you store cake?

Because this frosting has butter in it, it is best to refrigerate the cake if you will have it for more than 24 hours.. Make sure it is covered well so the cake doesn’t dry out.

Ingredients
 

For the cake:

  • 1 3/4 cups all-purpose flour 228 grams
  • 1 3/4 cups granulated sugar 350 grams
  • 3/4 cup unsweetened cocoa powder 75 grams
  • 1 teaspoon baking powder 4 grams
  • 2 teaspoons baking soda 10 grams
  • 2 teaspoons cinnamon 6 grams
  • ¼ teaspoon cayenne pepper optional (1 gram)
  • 1 teaspoon salt 8 grams
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 large eggs room temperature
  • 1 teaspoon vanilla
  • 1 cup freshly brewed strong hot coffee

For the frosting:

  • 1 cup salted butter at room temperature
  • 1 ½ teaspoons vanilla extract
  • 4 cups powdered sugar
  • 5-6 tablespoons heavy cream
  • 1 tablespoon cinnamon

For topping:

  • 1 cup mini chocolate chips

Instructions
 

Make the cake:

  • Spray a 9×13 baking pan with cooking spray. Preheat the oven to 350ºF.
  • For the cake, put flour, sugar, cocoa, baking powder, baking soda, cinnamon, cayenne pepper (optional) and salt in a large bowl and mix well.
  • In a stand mixer, mix the buttermilk, oil, eggs and vanilla together. Slowly add in the mix of dry ingredients while the mixer is on low. Add the coffee and make sure everything is combined. The batter will be very thin.
  • Pour batter into the prepared pan and bake for about 30-35 minutes or until the center of the cake springs back when you touch it. You can also insert a toothpick into the center and it should be mostly clean.
  • Allow the cake to cool on a cooling rack. While the cake is cooling, make the frosting.

Make the frosting:

  • Whip the butter alone in a stand mixer on medium for 2 minutes or until fluffy, almost white in appearance and lighter in texture.
  • Add the vanilla and cinnamon. Add the powdered sugar slowly, mixing between each addition.
  • Alternate the last bit of powdered sugar and the heavy cream, and whip the frosting on high for at least 2 minutes. If the buttercream is too thick after 5 tablespoons of heavy cream, add another tablespoon.
  • Spread the frosting over the cooled cake. Sprinkle the top with mini chocolate chips.
  • Store in an airtight container at room temperature.
