1-First Step: Cream the Butter and Sugars Place ½ cup softened butter in a large bowl. Add ⅓ cup granulated sugar and ⅓ cup brown sugar. Use an electric mixer on medium speed for 2 minutes until light and fluffy. Scraping sides ensures even mixing. This step aerates the dough for tender cookies. Room temperature butter blends best; microwave cold butter 10 seconds if needed.

2-Second Step: Add Wet Ingredients Beat in 1 egg and 1 tsp vanilla extract. Mix 1 minute until smooth. Egg adds lift, vanilla deepens flavor. Avoid overbeating to prevent tough cookies. If using yolk only for extra softness, save white for another use like meringues.

3-Third Step: Combine Dry Ingredients In a separate bowl, whisk 1 cup all-purpose flour, ½ tsp baking soda, and ¼ tsp salt. Gradually add dry mix to wet on low speed. Stir until just combined, no dry streaks. Overmixing activates gluten for flat cookies. Fold gently for best texture.

4-Fourth Step: Incorporate Chocolate Chips Add ¾ cup mini chocolate chips. Use a spatula to fold in evenly. Mini size prevents sinking. For extra chocolate, reserve 2 tbsp to press on tops before baking. Chill dough 30 minutes optional for thicker bites.

5-Fifth Step: Scoop and Shape Dough Scoop teaspoon-sized balls (about 1 inch diameter). Place 2 inches apart on sheets, 12 per sheet. Yields 36 cookies. Wet hands flatten slightly if desired. Space prevents merging during bake.

6-Baking Instructions: Bake one sheet at a time in middle oven rack 8-10 minutes. Edges golden, centers soft. Rotate halfway for even heat. Smaller size cooks fast; watch closely first batch. Cool on sheet 5 minutes, firm up, then rack. Prevents breakage.

7-Final Step: Finishing Touches and Serving Transfer to wire rack completely cool. Store or serve warm with milk. Drizzle melted chocolate or sea salt for flair. Pair with chocolate chip cookie dough ice cream for sundaes. Enjoy fresh or freeze for later. Troubleshooting: If flat, chill longer; if dry, add 1 tbsp milk next time.
