Cream together 1 cup of softened unsalted butter with ¾ cup of brown sugar and ¾ cup of granulated sugar in a large mixing bowl using an electric mixer on medium speed for 3-5 minutes.

Add in 1 large egg and 1 teaspoon of vanilla extract to the creamed mixture and mix until fully combined, about 1-2 minutes.

In a separate bowl, whisk together 2 ¼ cups of all-purpose flour, 1 teaspoon of baking soda, ½ teaspoon of baking powder, and ½ teaspoon of salt.

Gradually fold the dry ingredients into the wet mixture, taking care not to overmix.

Add 2-3 tablespoons of milk to the mixture to achieve the perfect dough consistency.

Gently fold in 1 cup of chopped Milky Way bars and ½ cup of milk chocolate chips until evenly distributed.

Cover the dough and refrigerate for 20-30 minutes.

Preheat your oven to 350°F (175°C). Scoop tablespoon-sized balls of dough onto lined baking sheets and bake for 9-12 minutes.

Let the cookies cool on the baking tray for about 10 minutes before transferring to a wire rack to cool completely.
