1-First Step: Prepare ingredients – Soften 1 cup butter at room temp. Measure 1.5 cups sugar, 2 eggs, 1 tsp vanilla. Whisk 3 cups flour, 1 tsp baking powder, 1/2 tsp salt in bowl. Have 1/2 cup sprinkles ready. Mise en place keeps things smooth, avoiding mid-mix pauses. For best results, use room-temp eggs to blend evenly.

2-Second Step: Cream butter and sugar – Beat butter and sugar 2-3 minutes until pale and fluffy. Scrape bowl sides. This incorporates air for soft cookies. Use paddle attachment on mixer or sturdy spoon. If butter melts, chill 10 minutes to firm up.

3-Third Step: Add eggs and vanilla – Beat in eggs one at a time, then vanilla. Mix until combined, about 1 minute. Dough may look curdled; its normal. This step binds wet ingredients for moisture.

4-Fourth Step: Incorporate dry ingredients – Add flour mixture gradually on low speed. Mix just until no streaks remain, 1-2 minutes. Overmixing toughens cookies. Fold in sprinkles gently to distribute color evenly. Avoid stirring too much to prevent color bleed.

5-Fifth Step: Chill dough – Cover bowl, refrigerate 30 minutes. Chilling firms dough, prevents spreading. Scoop 1-inch balls (use cookie scoop for uniformity) onto sheets, 2 inches apart. Roll smooth, dip tops in sugar for extra sparkle.

6-Sixth Step: Bake cookies – Bake 10-12 minutes until edges golden, centers soft. Rotate sheets halfway for even browning. Cool on sheet 5 minutes, then racks. Underbaking keeps chewy. Total active time 15 minutes.

7-Final Step: Finishing touches and serving – Once cool, store or enjoy. Drizzle melted chocolate for fancy look. Pair with iced tea for afternoon snack. Perfect for parties.
