Mexican Chocolate Cupcakes

Celebrate with these Mexican Chocolate Cupcakes topped with a Dulce de leche buttercream.

Left with a container of chocolate cupcake batter from a Cupcake Wars Class the day before, inspiration hit me. Cinco de Mayo was the perfect opportunity to make a spicy Mexican Chocolate Cupcake. Adding a little spice to chocolate creates a beautiful combo of flavors.

How to make Mexican Chocolate Cupcakes

You can use your favorite chocolate cake batter or even a cake mix as the base for these cupcakes. I love to bake, but I am also very practical. Also, my years as a Betty Crocker blogger taught me how easy it is to create decadent treats from a boxed cake mix.

Mexican Chocolate Cupcakes are spiced with cinnamon and chili powder, maybe a hint of cayenne pepper. You want a slight hint of heat, nothing overpowering.

I decided to to my cupcakes with a Cinnamon Dulce de Leche buttercream. But there is more. I punched out a small circle from each cupcake and filled it with a bittersweet chocolate ganache. The final touch is a sprinkle of crushed cinnamon graham crackers and shavings of bittersweet chocolate.

Biting into these cupcakes you get a kick but also this decadent chocolate ganache and a creamy buttercream. It is so good. They will never know you made it from a boxed cake mix.

Mexican Chocolate Cupcakes with Dulce de Leche Buttercream

  • Total Time: 35 minutes
  • Yield: 24 cupcakes 1x


Mexican Chocolate Cupcakes with a dulce de leche buttercream have a kick of spice of cayenne pepper with a buttercream sweetened with dulce de leche cream.


Units Scale
  • 1 18.25 oz. box Milk Chocolate cake mix
  • 1 cup buttermilk
  • 1/2 cup canola oil
  • 1 1/2 tsp. cinnamon
  • 1/2 tsp. chili powder
  • 1/4 tsp. cayenne
  • 4 eggs
  • 1 stick butter (room temperature)
  • 1/2 cup dulce de leche
  • 1/4 cup milk
  • 1 tsp. cinnamon
  • 2 1/2 cups powdered sugar (more or less to achieve desired consistency)
  • 1 teaspoons vanilla


  1. Preheat the oven to 350 degrees. Line 24 muffin cups with paper liners.
  2. Add the first six cake ingredients together in a large mixing bowl. Beat with an electric mixer on low to medium speed until moistened, about 30 seconds. Add eggs one at a time, until the batter is well-mixed. Increase speed to high and beat until thick, 2 minutes longer.
  3. Pour or scoop the batter into the paper liners until they are 2/3 full. Bake for 15-20 minutes, or until a toothpick inserted in the middle comes out clean. Remove from oven and let cupcakes cool on a wire rack.
  4. To Make Frosting:
  5. Cream butter in an electric mixer on medium-speed until smooth and fluffy, about 2-3 minutes. Then add dulce de leche, vanilla and cinnamon and mix on low-speed until combined. Gradually add in the milk and powdered sugar, alternately, until combined. Then beat on medium speed until light and fluffy, another 3-5 minutes. (Add in more powdered sugar if consistency is too thin.)
