Cinnamon Brownies

These cinnamon brownies lean into the classic Mexican chocolate pairing of cocoa and warm cinnamon, with a generous teaspoon-and-a-half of cinnamon in both the batter and the cocoa frosting. The result is a deep, fudgy brownie with a warming spice note that comes through after the chocolate hits, not in place of it.

Blooming the cocoa is the trick that makes these taste richer than the ingredients suggest. Stirring boiling water into the cocoa-butter mixture releases the cocoa’s flavor compounds, deepening the chocolate hit before any sugar or flour shows up. Skip this step and the brownies taste flatter, even with the same cocoa amount.

The frosting is essential, not optional. The combined cinnamon hit (in the batter and the frosting) is what creates the layered warmth. Skip the frosting and you’ve got a decent cinnamon brownie; include it and you’ve got something distinctive.

Pro Tips

• Use Dutch-process cocoa powder if you have it; it gives a deeper, darker chocolate flavor.
• Don’t overbake; pull when a toothpick has moist crumbs, not clean, for fudgy texture.
• Frost only when the brownies are fully cooled; warm brownies melt the frosting into a mess.
• Use a hot knife wiped clean between cuts for the sharpest brownie edges.

Variations

• Add ¼ teaspoon cayenne pepper to the batter for a true Mexican hot chocolate brownie.
• Stir in 1 cup chopped pecans or walnuts as the recipe suggests.
• Swap the cinnamon frosting for a cream cheese frosting for a tangy contrast.
