Mexican Hot Chocolate Sheet Cake with Warm Cinnamon Frosting
Mexican hot chocolate has always brought the warmth and comfort of the holidays into my kitchen. The aroma of cinnamon, rich cocoa, and that unmistakable depth from a hot chocolate tablet feels like the kind of flavor you only experience when the weather cools and the baking season kicks in. When I began shaping this recipe, I drew directly from those holiday flavors and folded them into the structure of my Texas Sheet Cake, a recipe I have relied on for years because of its simplicity and its ability to feed a crowd.
The idea was simple. Take the heart of that classic cake and introduce the flavors of Mexican hot chocolate into every layer. The tablet melts into the batter and creates a chocolate flavor that carries a gentle warmth instead of just sweetness. The frosting picks up those same notes, balancing richness with spice and making the entire cake feel connected to the season. It is a holiday-inspired version of a reliable classic, designed to be shared at family gatherings, potlucks, or after a full afternoon tending the smoker. This dessert brings tradition, nostalgia, and comfort together in one pan.

This recipe begins with the classic structure of my Texas Sheet Cake, then takes a seasonal turn using Nestlé Abuelita Mexican Hot Chocolate as the star flavor. The 3.1 ounce tablet has a depth and warmth you cannot get from cocoa alone, thanks to its natural cinnamon notes and signature chocolate richness. When it melts into the batter, it creates a soft, tender cake with a flavor profile that fits right into holiday baking. The sour cream keeps the crumb moist, while the vanilla adds roundness and balance.
The frosting carries that same energy. A portion of the Abuelita tablet is melted with heavy cream, butter, cinnamon, molasses, and vanilla paste to create a warm, pourable frosting that settles over the cooled cake in a smooth, flavorful layer. If desired, you can finish the cake with optional semisweet chocolate chips for an extra burst of texture. This recipe maintains the simplicity and reliability of a Texas Sheet Cake while celebrating the cozy, comforting flavor of Mexican hot chocolate. It is a dessert built for sharing, celebrating, and savoring the holiday season.

1 cup semisweet chocolate chips
Directions
- Prepare the Cake Batter: Preheat the oven to 350 degrees F and grease an 18 by 13 inch sheet pan. Cut the Nestlé Abuelita tablet into fourths and measure out 3/4 of the tablet for the cake. In a large bowl combine flour, granulated sugar, baking soda, and salt. In a separate bowl mix sour cream, eggs, and vanilla paste. Add the sour cream mixture to the dry ingredients and stir until fully combined.
- Heat the Chocolate Mixture: In a saucepan combine water, butter, the measured portion of the Nestlé Abuelita tablet, and unsweetened cocoa powder. Warm over medium heat until the mixture reaches a boil. Remove from heat and pour the hot mixture into the batter. Stir by hand until the batter is smooth with no lumps remaining.
- Bake the Cake: Pour the batter into the prepared sheet pan and spread evenly. Bake for 15 to 20 minutes or until the cake is set and springs back lightly when touched.
- Make the Frosting: Add powdered sugar to a large mixing bowl. In a saucepan combine heavy cream, salted butter, 1/4 of the Nestlé Abuelita tablet, Mexican cinnamon, vanilla paste, and molasses. Bring to a full boil, then remove from heat and pour into the powdered sugar. Blend with a hand mixer until fully smooth.
- Frost the Cake: Allow the cake to cool completely. Pour the warm frosting over the cooled cake and spread evenly. Let the frosting cool and set.
Finish the Cake (optional): After the frosting has cooled, sprinkle semisweet chocolate chips evenly over the surface.
