Preheat the oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting.

Whisk the melted butter and sugar in a large bowl until glossy. Whisk in the eggs and vanilla until smooth.
03 -
Stir in the cocoa powder, flour, salt, and baking powder just until combined. Fold in 3/4 cup of the chocolate chips.
04 -
Spread the batter evenly in the pan. Bake for 26-30 minutes, until the edges are set and a toothpick inserted near the center comes out with moist crumbs.
05 -
Cool completely in the pan. Lift out with the parchment and cut into 16 squares, wiping the knife between cuts for cleaner edges.
06 -
Melt the remaining 1/4 cup chocolate chips in short microwave bursts, stirring until smooth.

Use small dabs of melted chocolate to attach two pretzel antlers, two candy eyes, and one red candy nose to each brownie. Let set before serving.
