Preheat the oven to 350F (177°C) and line two cookie sheets with parchment paper. Set aside.
Melt the butter using a double boiler method or in the microwave. As it cools, prep the rest of your ingredients.
In a large bowl, add cooled melted butter and brown sugar. Whisk together.
3/4 cups light brown sugar, 1/4 cup butter
Add in egg and vanilla and continue whisking.
1 egg, 1 tbsp vanilla
Add in flour, cocoa powder, baking powder, and salt. Using a spatula, fold until a soft dough forms.
1 cup flour, 1/2 cup unsweetened cocoa powder, 1/4 tsp salt, 1 tsp baking powder
Toss in chopped Ghirardelli squares and chocolate chips. Mix in a few times.
9 Ghirardelli Peppermint Bark Squares, 1/3 cup semi-sweet chocolate chips
Using a cookie scooper, scoop 5-6 cookies per prepared baking tray.
Bake the cookies for 10-12 minutes. When ready, remove from oven and tap a few times against your countertop. This will help spread the cookies a bit.
Allow to cool, and enjoy!
