Ingredients

Hot Cocoa Brownies

  • 1/2 c unsalted butter
  • 3/4 c granulated sugar
  • 4 oz semi-sweet chocolate chips
  • 3/4 c all-purpose flour
  • 1/4 c hot cocoa mix
  • 1/2 tsp fine salt
  • 2 large eggs room temperature
  • 1 tsp vanilla extract
  • 8 large marshmallows cut in half

Instructions

Preheat the oven.

  • Preheat the oven to 350°F.

Prepare the baking pan.

  • Spray a 9x9-inch baking pan with baking spray and line it with parchment paper. Set aside.

Melt the butter and sugar.

  • In a microwave-safe bowl, combine the unsalted butter and granulated sugar. Microwave in 30-second intervals until the butter is melted and the mixture is hot and slightly bubbling around the edges. This will typically require 3 to 4 intervals, depending on the temperature of the butter.

Add the chocolate chips.

  • Once the butter and sugar mixture is hot and bubbling slightly, whisk in the semi-sweet chocolate chips until melted and smooth.

Add the dry ingredients.

  • Add the all-purpose flour, hot cocoa mix, and fine salt to the chocolate mixture.

Combine the batter.

  • Whisk until the dry ingredients are fully incorporated.

Add the eggs.

  • Whisk in the eggs one at a time, mixing well after each addition.

Add the vanilla.

  • Whisk in the vanilla extract until fully combined.

Transfer the batter.

  • Pour the brownie batter into the prepared baking pan and spread it evenly.

Bake the brownies.

  • Bake for 25 minutes.

Add the marshmallows.

  • Remove the brownies from the oven and arrange the halved marshmallows in a grid-like pattern over the top.

Warm the marshmallows.

  • Return the brownies to the oven and bake for an additional 2 to 3 minutes, or until the marshmallows are warmed and lightly golden.

Press the marshmallows.

  • Remove the brownies from the oven. Using the back of a spoon, gently press the marshmallows down slightly.

Finish baking.

  • Return the brownies to the oven and bake for an additional 2 to 3 minutes, or until the marshmallows are fully golden.

Cool completely.

  • Remove the brownies from the oven and allow them to cool completely in the pan.

Slice and serve.

  • Use the parchment paper to lift the cooled brownies from the pan. Cut into 16 squares and serve.

Notes

To make these Hot Cocoa Brownies gluten free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Verify that the hot cocoa mix, semi-sweet chocolate chips, marshmallows, vanilla extract, baking spray, and all packaged ingredients are labeled gluten free or free from gluten-containing additives. Use clean mixing bowls, measuring cups, utensils, baking pan, and parchment paper to prevent cross-contact with gluten-containing ingredients.
