Brownie Cookies

Oh, yeah baby!  You get the chewiness and yumminess of a brownie into a perfect cookie! You seriously can't get better than this!  My beautiful daughters made these for our family and, needless to say, they were all gone almost immediately.  Enjoy!
-1/2 cup (1 stick) unsalted butter
-2 cups semi sweet chocolate chips, divided
-3 large eggs
-1 cup sugar
-1/4 cup brown sugar
-1 Tbs vanilla extract
-1/2 tsp baking powder
-1/2 tsp salt
-1/4 cup unsweetened cocoa powder
-3/4 cup flour
In a small sauce pan, melt the butter and 1 1/2 cups of the chocolate chips. Remove from the heat and set aside.
In your electric mixer's bowl, beat the eggs, sugar and brown sugar. Stir in the vanilla, baking powder and salt.  Mix very well.  Beat on high for 5 minutes to make it all nice and fluffy.
Reduce the speed to low and add the cooled melted chocolate mixture. Mix well. Stir in the cocoa powder and flour.  Mix very well.  Add the remaining chocolate chips. Mix well.
cover the batter and refrigerate for 30 minutes.
Preheat oven to 350 F.
Line a couple of baking sheet with parchment paper. Scoop batter onto prepared sheets.
Bake cookies in preheated oven for 15 minutes. The cookies will look set at the edges, but still a little wet looking in the center.  That's how you want them to look to get the fudgy texture.
Remove cookies from the oven and set the trays on wire racks.  Let cool for 10-15 minutes.  Enjoy!
