Preheat your oven to 350°F (175°C) and prepare your baking sheets by lining them with parchment paper.

In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.

In a separate bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy for about 2-3 minutes.

Beat in the egg, vanilla extract, and butter extract (if using) until smooth and well blended.

Gradually mix the dry ingredients into the wet ingredients until a soft dough forms, being careful not to overmix.

Fold in the butterscotch chips until evenly distributed throughout the dough.

Drop rounded tablespoons of dough onto the lined baking sheets, spacing them about 2 inches apart.

Bake in the preheated oven for 10-12 minutes or until the edges are set and tops are lightly golden brown.
