Instructions

Prep the Pan

Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or lightly grease it.

Melt the Butter

In a medium saucepan or microwave-safe bowl, melt the butter. Let it cool slightly so it doesn’t scramble the eggs.

Mix the Wet Ingredients

In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until glossy. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.

Add the Dry Ingredients

Sift in the cocoa powder, flour, salt, cinnamon, cayenne, and espresso powder if using. Stir just until combined—do not overmix.

Fold in Chocolate

Fold in the chocolate chips or chopped chocolate for extra gooey texture.

Fill the Pan

Spread the batter evenly into the prepared pan. If using, sprinkle the cinnamon sugar topping over the batter.

Bake

Bake for 30 to 35 minutes, or until the center is just set and a toothpick inserted comes out with a few moist crumbs (not wet batter). For fudgier brownies, avoid overbaking.

Cool and Finish

Let the brownies cool completely in the pan before slicing. If desired, melt the chocolate chips with coconut oil and drizzle over the cooled brownies.

Slice and Serve

Cut into squares and serve slightly warm or at room temperature.

Notes

Cooking Tips

Use good cocoa powder for the richest chocolate flavor.
Don’t skip the cinnamon—it gives these brownies that signature Mexican hot chocolate flavor.
Start light with cayenne if you’re unsure about spice; even a little adds warmth.
Underbake slightly for extra fudgy brownies.
Let them cool fully before slicing for cleaner edges.
Add flaky sea salt on top for a sweet-spicy-salty finish.
Use chopped dark chocolate instead of chips if you want melted chocolate pockets throughout.

Variations

Increase the cayenne to 1/2 tsp for a stronger kick.

3. Frosted Brownies

4. Walnut or Pecan Brownies

5. Dulce de Leche Swirl

Swirl 1/3 cup dulce de leche into the batter before baking.

6. Marshmallow Hot Chocolate Brownies

Top with mini marshmallows during the last 3–4 minutes of baking.

7. Dark Chocolate Version

Use bittersweet chocolate and reduce granulated sugar slightly for a richer taste.

8. Gluten-Free Option

Swap the all-purpose flour for a 1:1 gluten-free baking blend.

9. Holiday Brownies

Dust the cooled brownies with powdered sugar and cinnamon for a festive finish.

10. Brownie Sundae Style

Serve warm with vanilla ice cream and extra chocolate drizzle.
