How to Make Mexican Hot Chocolate Brownies (Step-by-Step Guide)

Step 1: Prepare the Baking Pan

Start by preheating your oven to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper or foil, leaving a little overhang on the sides so you can easily lift the brownies out later. Lightly spray with nonstick cooking spray.

Step 2: Melt the Chocolate, Butter, and Sugar

In a large heat-proof bowl, combine the butter, chopped dark chocolate, and granulated sugar. Microwave in 30-second intervals, stirring between each burst until everything melts and becomes smooth. Once melted, let the mixture cool for about 10–15 minutes until it’s just slightly warm.

Step 3: Add the Wet Ingredients

Now whisk in the canola oil, eggs, egg yolk, and vanilla extract. Keep whisking for about 30–40 seconds until the batter looks smooth, glossy, and well combined. This step helps create that signature fudgy brownie texture.

Step 4: Mix the Dry Ingredients

In a separate medium bowl, whisk together the flour, cocoa powder, baking soda, cornstarch, cinnamon, salt, and cayenne pepper until everything is well combined. Mixing the dry ingredients first helps ensure that the spices and cocoa are evenly distributed throughout the batter, giving the brownies their signature Mexican hot chocolate flavor with warm cinnamon and a subtle hint of spice in every bite.

Step 5: Combine Wet and Dry Ingredients

Gradually add the dry ingredients into the chocolate mixture. Using a rubber spatula, gently fold everything together until just combined.

Step 6: Add the Chocolate Chips

Fold in the semisweet chocolate chips. These will melt slightly while baking and create delicious pockets of gooey chocolate in the brownies.

Step 7: Spread the Batter in the Pan

Pour the brownie batter into your prepared pan and spread it evenly using a spatula so it reaches all corners.

Step 8: Bake the Brownies

Place the pan in the oven and bake for about 35 minutes. To check if they’re ready, insert a toothpick into the center. It should come out with a few moist crumbs attached, but not wet batter.

Step 9: Let the Brownies Cool

Once baked, remove the pan from the oven and let the brownies cool completely in the pan for about 1 hour. This helps them set properly before adding the topping.

Make the Chocolate Ganache Topping

Prepare the Ganache

Place the chocolate chips in a heat-proof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to boil. Pour the hot cream over the chocolate and let it sit for 5–8 minutes. Then gently stir until the chocolate melts completely and the mixture becomes smooth. Stir in the cinnamon and a pinch of salt.

Add the Ganache Layer

Allow the ganache to cool slightly so it thickens a little. Reserve about 2 tablespoons in a piping bag for decoration. Pour the remaining ganache over the cooled brownies and spread it evenly across the surface.

Add the Marshmallow Topping

Now sprinkle or gently press the mini marshmallows into the ganache, so they cover the surface. Place the pan under the broiler for about 90 seconds until the marshmallows turn golden and lightly toasted.

Chill and Finish

Place the brownies in the refrigerator for about 30 minutes so the ganache can set. Once firm, drizzle the reserved ganache over the top for a beautiful finishing touch.

Slice and Serve

Lift the brownies out using the parchment overhang and cut into 9 large or 16 smaller squares. Now enjoy your Mexican Hot Chocolate Brownies, rich, fudgy, slightly spicy, and topped with gooey toasted marshmallows!

Expert Baking Tips For Perfect Mexican Hot Chocolate Brownies

1. Use good-quality chocolate: Since chocolate is the star ingredient, using high-quality dark chocolate and cocoa powder will give your brownies a deeper and richer flavor.

2. Don’t skip the cooling time: Letting the brownies cool completely before adding the ganache helps the topping set properly and prevents it from melting into the brownies.

3. Adjust the spice level: Mexican hot chocolate is known for its warm spice. If you prefer mild brownies, use ¼ teaspoon cayenne. If you enjoy heat, increase it slightly.

4. Watch the marshmallows while broiling: Marshmallows toast quickly under the broiler, so keep an eye on them. They can go from perfectly golden to burnt in seconds.

5. Use parchment paper for easy removal: Lining the pan allows you to lift the brownies out cleanly, making slicing much easier.

Common Mistakes to Avoid

• Overbaking the brownies: Brownies continue cooking slightly after coming out of the oven. If baked too long, they can become dry instead of fudgy. Remove them when the center is still moist with crumbs.
• Adding eggs to the hot chocolate mixture: If the chocolate mixture is too hot, the eggs may scramble and ruin the batter. Let it cool slightly before whisking them in.
• Skipping the cinnamon or cayenne: These spices are what make this recipe special. Without them, the brownies will taste like regular chocolate brownies instead of Mexican hot chocolate brownies.
• Pouring ganache while the brownies are hot: Hot brownies will cause the ganache to melt too much and become messy. Always cool brownies completely first.

• Chocolate Chunk Version: Replace chocolate chips with large chocolate chunks for bigger melty pockets.

• Caramel Drizzle: Drizzle a little caramel sauce on top for a sweet contrast to the spice.
