Triple Chocolate Oatmeal Cookie

Instructions

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. Set aside.

3. In a separate large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

4. Add the egg and vanilla extract to the butter-sugar mixture, beating until smooth and well incorporated.

5. Gradually add the dry flour mixture to the wet ingredients, mixing until just combined.

6. Stir in the old-fashioned oats, semisweet chocolate chips, milk chocolate chips, and white chocolate chips until evenly distributed throughout the cookie dough.

7. Using a cookie scoop or a spoon, portion out the dough onto the prepared baking sheet, spacing them 2 inches apart to allow for spreading during baking.

8. Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are lightly golden but the centers are still slightly soft.

9. Remove the baking sheet from the oven and let the cookies cool on the pan for 5 minutes before transferring them to a wire rack to cool completely.
