Cream the Butters and Sugars: In a large mixing bowl, beat ¾ cup of softened unsalted butter with ½ cup of granulated sugar and ½ cup of brown sugar until light and fluffy, 2-3 minutes.

Add the Egg and Vanilla: Incorporate 1 large egg and 1 teaspoon of vanilla extract into the butter-sugar mixture and beat until fully combined.

Whisk the Dry Ingredients: In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt until well combined.

Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the butter-sugar mixture, folding gently until just combined.

Chill the Dough: Wrap the dough in plastic and refrigerate for at least 30 minutes.

Preheat the Oven: While the dough chills, preheat your oven to 350°F (175°C).

Shape and Bake the Cookies: Scoop tablespoon-sized balls, place on a lined baking sheet, and bake for 8-10 minutes until edges are set.

Cool and Enjoy: Allow cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
