How To Make Mexican Chocolate Cake

😉 The real magic of this cake begins on the stovetop. **

1. Mix the dry ingredients
Whisk everything together in a large bowl.

2. ** Make the chocolate base (this is the secret)
Melt butter and cocoa together on the stovetop until smooth and glossy.

3. Combine and mix
Pour the warm chocolate mixture into the dry ingredients and stir until smooth.

4. Add eggs and buttermilk
Mix until you have a thin, silky batter.

5. Bake
350°F for 18–20 minutes, until it is set. A cake tester will come out clean, and the top of the cake will spring back when you touch it.

When the Mexican chocolate cake is done baking, it should pull back slightly from the edges of the pan. Let the cake cool for only about 10 minutes.

The Warm Chocolate Icing That Soaks Into the Cake

Get busy making the icing while the cake bakes, so both the cake and the icing are nice and warm when they meet! The icing is poured over the cake while it’s still warm, so it melts right in and creates that rich, fudgy top layer. Don’t skip this step—this is what makes this cake unforgettable.

Use the same saucepan (just rinse it out) to melt the butter, milk, cocoa, and salt. Cook it over medium heat, just to the point of simmering. Remove the pan from the stove and stir in the powdered sugar and pecans. Keep the icing warm and stir it occasionally to keep a crust from forming on top.

Let the iced cake cool for about twenty minutes before serving. I highly recommend ice cream on top. Vanilla is awesome, but it’s even more fantastic if you can find cinnamon ice cream!

    1. I have never frozen it myself, but it should freeze beautifully either way. let it cool completely, then wrap it in plastic film , then in foil, and you should be golden!

    1. Absolutely!I'd wrap it in Saran wrap and then with foil. Make sure the icing is set first! It's a good keeper and it freezes well, too.
