Did you know that the combination of chocolate and cinnamon is a classic Mexican dessert flavor? This fabulous Mexican chocolate cake is perfect for a Cinco de Mayo celebration.

While most chocolate cakes start by beating butter and sugar together, this is a saucepan cake. It starts by melting butter with chocolate and water in a saucepan. That makes the cake moister, and also enhances the chocolate flavor of the cake. It also means this cake is easier to make!

The frosting for the cake is also a saucepan frosting, which is simpler than a classic buttercream frosting. Pour the frosting onto the cake while they are both warm. That will create a fudgy layer underneath the frosting that is simply delectable.

You can add more cinnamon to this cake if you'd like. Increase it up to 2 teaspoons; in the cake, and up to 1/2 teaspoon in the frosting but don't go much higher than that. 


  • For the Cake
  • 4 (1-ounce) squares unsweetened chocolate
  • 1/2 cup butter
  • 1 cup hot water
  • 2 cups flour
  • 2 cups sugar
  • 1 teaspoon cinnamon
  • Pinch of salt
  • 1/3 cup buttermilk
  • 1 1/4 teaspoons baking soda
  • 2 eggs (beaten)
  • 2 teaspoons vanilla
  • For the Frosting
  • 2 (1-ounce) squares unsweetened chocolate
  • 1/4 cup butter
  • 8 tablespoons milk
  • 4 cups powdered sugar
  • 1/4 teaspoon cinnamon
  • 1 teaspoon vanilla

Steps to Make It

For the Cake

  1. Preheat the oven to 350 F.

  2. Spray a 9 x 13-inch pan with nonstick baking spray containing flour and set aside.

  3. In a large saucepan, melt 4 squares of chocolate and 1/2 cup of butter in the hot water and bring to a boil.

  4. Remove from heat and add the flour, sugar, 1 teaspoon cinnamon, and salt. Mix well with a wire whisk or eggbeater.

  5. Then stir in the buttermilk, baking soda, eggs, and 2 teaspoons vanilla and beat until smooth.

  6. Pour the batter into the prepared pan.

  7. Bake for 25 to 30 minutes, until the top springs back when touched with a fingertip. The cake should pull away from the sides of the pan slightly.

For the Frosting

  1. While the cake is baking, make the frosting. In a heavy saucepan, melt 2 squares of the chocolate and 1/4 cup butter together.

  2. Add powdered sugar, milk, 1/4 teaspoon cinnamon, and 1 teaspoon vanilla and beat well. You may need to add more milk or powdered sugar to reach the desired consistency: the frosting should be pourable and smooth, not stiff and spreadable.

To Assemble the Cake

  1. When the cake comes out of the oven, let it cool on a wire rack for 15 minutes.

  2. Then pour the frosting over. Spread if necessary, and let the cake cool.

  3. Slice, serve, and enjoy!
