- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup butter, softened
- 3/4 cup white sugar
- 3/4 cup brown sugar
- 2 eggs
- 1 1/2 cups quick-cooking rolled oats
- 2 cups butterscotch chips, divided
- Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking pan.
- In a bowl, whisk together the flour, baking powder, baking soda, and salt.
- In a large mixing bowl, mash the butter, white sugar, and brown sugar together until smooth and creamy, and beat in the eggs to make a creamy mixture. Gradually beat in the flour mixture, rolled oats, and 1 1/2 cup of butterscotch chips.
- Press the dough into the prepared baking dish, and sprinkle the top with remaining 1/2 cup of butterscotch chips.
- Bake in the preheated oven until the top is golden brown, 30 to 35 minutes. Allow to cool in the pan before cutting into bars and serving.
