Preheat your oven to 350°F and prepare an 8x8-inch baking pan by greasing it and lining it with parchment paper, leaving a bit hanging over the edges for easy removal later. Set the pan aside.

In a medium saucepan, add sliced butter and heat over medium, stirring occasionally. Let it melt and cook until it reaches a light golden brown and gives off a nutty aroma—this should take about 5 to 8 minutes. It will foam up, so keep an eye on it. Once browned, remove from heat and stir in the chocolate until smooth and fully melted. Let it cool slightly.

In a large mixing bowl, combine both sugars and eggs. Beat the eggs and sugars together until light, fluffy, and pale in color.

Add the vanilla, cocoa powder, and slightly cooled butter-chocolate mixture to the egg mix and whisk to combine.

Gently fold in the flour, salt, and chocolate chips until just mixed—be careful not to overmix it!

Pour the brownie batter into your prepared pan and bake in the center of the oven for 25 to 30 minutes, or until the top is no longer shiny and a toothpick comes out with moist crumbs.

Allow the brownies to cool completely in the pan. Once cooled, use the parchment paper to lift them out and cut them into triangles.

For decorating, mix red food coloring into the frosting, then pipe it on each triangle to make little Santa hats. Add marshmallow cream for the “fur” trim and top with a mini marshmallow. Enjoy your festive, fudgy Santa Hat Brownies!
