Stolen from lisamichele's wordpres.s blog
The dough is very similar to shortbread. Not like Tollhouse-style.

2 sticks cold and cubed unsalted butter
3/4 cup granulated sugar
1 cup brown sugar
2 eggs
3 1/4 cups AP flour- dough should be moist, but not super sticky
3/4 tsp Kosher salt
3/4 tsp baking powder
1/4 tsp baking soda
1 cup semi-sweet chocolate chunks
1 cup milk chocolate chips
1 cup toasted walnuts- also good with macadamia

Preheat oven to 350.
In bowl of electric mixer fitted with a paddle, cream together butter and sugars until well blended & fluffy. Add eggs one at a time & beat until well-incorporated.

Add flour, salt, baking soda, baking powder & mix until just combined. Gently fold in chocolate chunks and nuts.

Transfer dough to clean work surface and gently mix dough by hand to ensure even distribution of ingredients. Divide into 10 equal portions- 3 per cookie sheet.

Place each on heet pan lined with parchment paper and bake in preheated oven or 16-23 minutes. Bake until lightly browned. Cool completely on the cookie sheet itself, then transfer to wire rack. Store in airtight container or freeze leftovers.
