1-First Step: Mise en Place and Dry Ingredients Preheat oven to 375°F. Line two baking sheets with parchment paper. In a medium bowl, whisk together 2 1/4 cups bread flour, 1 tsp baking soda, and 1 tsp salt. This ensures even distribution and prevents dense spots. Set aside. Pro tip: Measure flour by spooning into cup and leveling for accuracy, avoiding packed dough.

2-Second Step: Cream Butter and Sugars In a large bowl, beat 1 cup softened unsalted butter, 3/4 cup brown sugar, and 3/4 cup white sugar with a mixer on medium for 3-4 minutes. Scrape sides often. The mixture should turn pale, fluffy, and voluminous, trapping air for tender cookies. If lumpy, soften butter more next time. This step mimics the bakery aeration for lightness.

3-Third Step: Add Wet Ingredients Beat in 1 tsp vanilla extract and 2 eggs one at a time, mixing 30 seconds each. Batter may look curdled; that’s normal. Scrape bowl thoroughly. The eggs add moisture and lift, creating steam pockets during baking for chewiness.

4-Fourth Step: Combine Wet and Dry Gradually add dry mixture to wet on low speed until just combined, about 1 minute. Avoid overmixing to keep gluten relaxed for softness. Dough will be thick and sticky.

5-Fifth Step: Fold in Chips and Nuts Gently fold in 2 cups mini chocolate chips and 1 cup optional chopped toasted walnuts with a spatula. Use minis for no-sink chips and even bites. Chill dough 30 minutes (or overnight) covered; this firms it up for perfect scoops and intensifies flavor.

6-Sixth Step: Scoop and Bake Scoop 1-tbsp (1.5-inch) balls onto sheets, 2 inches apart (about 20 per sheet). Bake 8-10 minutes until edges golden, centers soft. Rotate sheets halfway. They firm on cooling.

7-Final Step: Cool and Serve Cool on sheet 5 minutes, then racks. Store airtight. Enjoy warm with milk or as funfetti Greek yogurt muffins for a bake sale spread. Yields 60 cookies; double for parties.
