Chop the chocolate peppermint bark into small chunks. Set aside.1 cup chopped chocolate peppermint bark
Using an electric mixer cream the butter and sugar together until soft and fluffy. This will take 10-15 minutes. Make sure to the scrape the sides of the bowl several times during this mixing.1 cup butter, 1 1/4 cup granulated sugar
Once the sugar and butter mixture is fluffy, add the egg and vanilla. Mix well.1 large egg, 1 1/2 tsp vanilla extract
In a separate bowl whisk together the flour, baking powder and salt.2 1/2 cups all purpose flour, 2 tsp baking powder, 1/4 tsp salt
Add the dry ingredients to the wet ingredients and mix well.
Stir in the chopped peppermint bark.
Roll the cookie dough into 1 1/2 inch balls.
Place the dough balls on a parchment paper lined cookie sheet about 1 1/2 inches apart, and flatten the tops slightly (see picture above).
Tip! I like to add a few extra chunks of peppermint bark to the tops of each cookie before baking (it looks nice).
Bake for 10 minutes (the edges should be only slightly golden).
