1-First Step: Soften 1 cup unsalted butter at room temperature for 20-30 minutes. Measure 2 1/2 cups all-purpose flour, 1 cup granulated sugar, 1/2 tsp baking powder, and 1/4 tsp salt into separate bowls. Have 1 large egg, 1 tsp vanilla extract, and 1/2 cup colorful sprinkles ready. Line two baking sheets with parchment paper or silicone mats. This setup keeps things smooth and prevents last-minute scrambles.

2-Second Step: In a large bowl, beat softened butter and sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes. Scrape down the sides for even mixing. Add the egg and vanilla extract, beating until fully incorporated, another 1 minute. This creaming method traps air for tender results.

3-Third Step: In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to the wet mixture on low speed, mixing just until a dough forms. Avoid overmixing to keep cookies soft. The dough will be slightly sticky but manageable.

4-Fourth Step: Divide dough in half, flatten into discs, and wrap in plastic. Chill in the fridge for 1 hour or freezer for 30 minutes. Chilling prevents spreading and makes rolling easier. Preheat oven to 350°F (175°C) during the last 15 minutes of chilling.

5-Fifth Step: On a lightly floured surface, roll one disc to 1/8-inch thickness. Use 1- to 2-inch round cutters to cut shapes, re-rolling scraps once. For smaller 1-inch cookies, you’ll get more minis; 2-inch yield fewer but chunkier bites. Place 1 inch apart on prepared sheets.

6-Sixth Step: Bake at 350°F for 8-10 minutes. Watch closely: 1-inch minis take 7-8 minutes, 2-inch closer to 10. Edges should be lightly golden, centers pale. For sprinkle cookies, gently press sprinkles onto warm cookies right after baking or roll dough edges in sprinkles before baking.

7-Final Step: Cool on the sheet for 2 minutes, then transfer to a wire rack. Let cool completely before storing or decorating. These hold shape well for parties. Total time: about 2 hours including chill. Pair with a refreshing lemonade for the ultimate treat.
