Brownie Pillow Cookies

I can't remember where I first saw these cookies. I've tried the brownie/chocolate chip cookie mixes from the grocery store before but they never quite come out right, so this recipe intrigued me.

Brownie Pillow Cookies

 For the brownie:

1/2 c butter, melted

1 c sugar

1 tsp vanilla extract

2 eggs

1/2 c all-purpose flour

1/3 c cocoa powder

1/4 tsp baking powder

1/4 tsp salt

For the cookies:

1 c butter, room temperature

1 1/2 c packed light brown sugar

2 large eggs, plus 1 egg yolk

1 T vanilla extract

2 1/2 c all-purpose flour

2 tsp baking powder

1/2 tsp salt

1/2 tsp baking soda

12 oz bag semi-sweet mini chocolate chips

Preheat oven to 350. Grease a 9 inch square baking pan.

For the brownies, stir together butter, sugar and vanilla. Add eggs, beating well. In a separate bowl, stir together flour, cocoa, baking powder, and salt. Gradually add to egg mixture, beating until well blended. Spread evenly into pan and bake 20-25 minutes. Once cool, cut about 10 one inch squares.

For the cookies, beat butter until creamy. Add brown sugar and beat until smooth. Add eggs, yolk and vanilla, beating until smooth. In a separate bowl, combine flour, baking powder, baking soda, and salt. Add flour mixture to butter mixture and beat until combined. Stir in chocolate chips. Chill dough in refrigerator for an hour.

Scoop batter into 1/2 c portions. Place on parchment paper lined baking sheet. Make an indentation in the center and put brownie square into indentation. 

Work remaining dough into ball around brownie.

The cookies will get very large, so put only 4-5 per baking sheet. Bake for about 18 minutes.
