Easy, soft, and moist Mexican chocolate cake made with a cake mix and finished with spiced brown sugar frosting and a drizzle of chocolate ganache. This cake is warm with cinnamon, nutmeg, and a touch of cayenne for depth.

This cake highlights subtle Mexican-inspired spices that enhance the chocolate without overwhelming it. The cinnamon and nutmeg add warmth while a hint of cayenne lifts the chocolate’s complexity. Serve as-is or pair with other Mexican desserts for a themed spread.
How to make Mexican chocolate cake with a cake mix
- Mix wet ingredients – Combine eggs, melted butter, milk, and a prepared chocolate snack-pack pudding cup in a large bowl until smooth.
- Add dry ingredients – Stir in the chocolate cake mix, cinnamon, cayenne (to taste), and nutmeg.
- Mix gently – Combine until just incorporated; avoid overmixing to keep the cake light.
- Pour batter – Transfer the batter to a greased 9×13-inch pan and spread it evenly with a spatula or the back of a spoon.
- Bake – Bake at 350°F (175°C) for about 30–35 minutes, or until a toothpick inserted into the center comes out clean.
- Cool – Let the cake cool completely before decorating so the frosting doesn’t melt.
- Decorate – Spread spiced brown sugar frosting across the top, sprinkle mini chocolate chips, and finish with a drizzle of chocolate ganache.

Variations
- Different frostings and toppings – Try caramel frosting, chocolate ganache frosting, American buttercream, dulce de leche, sprinkles, cocoa nibs, powdered sugar, crushed cookies, or mini marshmallows.
- Layer cake – Bake in two 8×3-inch round pans for a layered presentation.
- Cupcakes – Divide batter among cupcake liners and bake according to the cake mix directions.
- Boost chocolate flavor – Add espresso powder to the batter for more depth.
- Gluten-free – Use a gluten-free chocolate cake mix.
- Use extracts – Try vanilla, caramel, or bourbon extract for added nuance.
- Spice up frostings – Add extra cinnamon, nutmeg, or a pinch of cayenne to the frosting or ganache.
- Less sweet option – Top with dark chocolate chips instead of semisweet.
Tips and techniques
- Avoid overmixing – Overmixing makes cakes dense and chewy. Stir until ingredients are just combined.
- Cool before frosting – Let the cake reach room temperature so the frosting holds its shape.
- Use snack-pack pudding – The recipe calls for a ready-to-eat chocolate snack-pack pudding cup, not dry pudding mix; this affects texture.
- Use large eggs – Large eggs provide consistent structure and a lighter texture.
- Butter vs. oil – Butter adds a richer flavor; oil yields a moister crumb but a different taste.
- Check doneness – The cake is done when a toothpick inserted in the center comes out clean.
- Adjust spices – Increase or decrease the cinnamon, nutmeg, and cayenne to match your taste.
- Don’t overbake – Overbaking dries the cake; remove it as soon as it’s set in the center.
- Even batter distribution – Smooth the batter in the pan so the cake bakes uniformly.
- Milk choice – Whole milk gives the richest result; 2% is an acceptable substitute.

Recipe FAQs
If the cake stuck, the pan likely wasn’t greased adequately. Line the bottom with parchment paper and grease the sides to prevent sticking.
A soggy center means the cake is underbaked or had too much liquid. Measure accurately and bake until a toothpick comes out clean.
Dry cake is typically overbaked or baked at too high a temperature, or it contains too much flour. Bake only until the center is set and measure ingredients precisely.
Opening the oven door during baking can cause a sudden temperature drop and lead to collapse. Avoid opening the door until near the end of baking.
Storage
- Refrigerate – Store in a sealed container in the fridge for up to 3 days.
- Freeze – Freeze unfrosted cake in an airtight container for up to one month. Thaw before frosting and serving.
- Reheat – Thaw from frozen and serve at room temperature or chilled.
