1- First Step: Brown the butter (mise en place). Place 1 cup unsalted butter in a light-colored saucepan over medium heat. Let it melt, then foam. Stir occasionally for 5-7 minutes until golden bits form and nutty smell develops. Remove from heat right away to prevent burning. Pour through a fine mesh sieve into a bowl, discarding solids. Cool to room temperature (about 30 minutes) or refrigerate briefly to soften. This step builds deep flavor; double it for future batches.

2- Second Step: Cream sugars and butter. In a large bowl, beat browned butter, 1 cup granulated sugar, and 1/2 cup powdered sugar with a mixer on medium for 2-3 minutes until light and fluffy. Scrape sides often. This incorporates air for tenderness. If butter is too soft, chill 10 minutes first.

3- Third Step: Add wet ingredients. Beat in 1 egg and 2 tsp vanilla extract until smooth, about 1 minute. The egg adds moisture and lift. Vanilla ties flavors together. Pause to scrape bowl for even mixing.

4- Fourth Step: Mix dry ingredients. Whisk 2 1/4 cups flour, 1/2 tsp baking soda, and 1/2 tsp salt in a separate bowl. Gradually add to wet mixture on low speed until just combined. Dough will be soft and sticky. Avoid overmixing to keep cookies chewy.

5- Fifth Step: Chill the dough. Cover bowl and refrigerate 1 hour (or up to 3 days). Chilling firms butter for better shape and intensifies flavor. Scoop 1.5-inch balls (about 2 tbsp each) onto a plate if prepping ahead.

6- Sixth Step: Shape and roll. Roll chilled dough balls in 1/4 cup coarse sugar to coat. Place 2 inches apart on baking sheets. Flatten slightly with palm for even baking. Sugar crystals sparkle and crunch.

7- Seventh Step: Bake. Bake at 350°F for 10-12 minutes. Edges turn golden; centers stay pale. Rotate sheets halfway for even heat. They firm as they cool.

8- Final Step: Cool and serve. Cool on sheet 5 minutes, then transfer to wire rack. Enjoy warm or store. Pair with lemonade for parties. Troubleshoot: Too spread? Chill longer. Pale? Add 1-2 bake minutes.
