1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Prepare Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt until well combined. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, using a hand mixer or a stand mixer fitted with the paddle attachment.
4. Fill Cupcake Liners: Divide the batter evenly among the cupcake liners, filling each liner about two-thirds full. An ice cream scoop can help with this process for even distribution.
5. Bake: Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
6. Cool: Remove the cupcakes from the oven and let them cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
