½cup(80g)mini semi-sweet chocolate chips

Instructions
Preheat oven to 350°F. Grease and line an 8-inch metal baking pan with parchment paper folded over the sides.
In a large bowl, cream together the softened butter and brown sugar until light and fluffy (about 2 minutes on medium speed with a mixer). Mix in the egg and vanilla extract well.
Mix the flour, baking powder, and salt into the wet ingredients just until the dry streaks disappear. Fold in the chocolate chips until evenly distributed.
Press half of the cookie dough into the bottom of the prepared pan. Dollop and spread a little over half of the Nutella across the top, followed by the remaining dough. Drop spoonfuls of Nutella over the top dough layer and swirl them around with a knife.
Bake the Nutella bars on the oven's middle rack until the edges are tan but center is still slightly gooey (about 25-30 minutes). Once they're firm enough, lift out of the pan and let them cool on a wire rack.
Slice into 9 or 16 equal squares and enjoy!
