Ingredients:
-2 sticks unsalted butter, at room temperature
-3/4 cup brown sugar
-1/4 cup granulated sugar
-2 eggs
-1 tsp vanilla
-2 1/4 cups all-purpose flour
-1 packet instant vanilla pudding (the small package)
-1 tsp baking soda
-1 tsp salt
-2 cups mix-ins (I used a combo of butterscotch, white, and chocolate chips, plus toasted coconut)

Directions:
1. Preheat oven to 350F. Grease a 9 x 13 inch pan and set aside.
2. Cream butter and sugars in a large mixing bowl until light and fluffy. Add the vanilla and the eggs, beating to combine. Mix in the pudding mix.
3. In a separate bowl, combine the flour, baking soda, and salt. Gradually add the flour mixture to the wet mixture, beating until combined. Stir in the mix-ins.
4. Spread dough in prepared baking sheet. Bake for 20-25 minutes, until edges are set but middle is still slightly gooey (you don't want to overbake!)
