Ultra Thick Bakery Style Chocolate Chip Cookies

Begin by whisking together the all‑purpose flour, whole‑wheat pastry flour, baking soda, and sea salt in a medium bowl. Whisking aerates the flour, which helps produce a lighter crumb. Once combined, set the bowl aside; the dry mixture will later absorb the wet ingredients evenly, preventing clumps and ensuring a uniform texture throughout each cookie.

Combining Wet Ingredients

1. Cool the Butter. After melting the butter, let it sit at room temperature for about 10 minutes until it’s warm but not hot. Warm butter integrates more easily with the sugars, creating a smooth, glossy base that helps the cookies spread evenly.
2. Mix Sugars & Butter. In a large mixing bowl, combine the melted butter, dark brown sugar, and granulated sugar. Beat with a handheld mixer on medium speed until the mixture lightens in color and becomes slightly fluffy, about 2‑3 minutes. This step dissolves some of the sugar, contributing to a tender interior.
3. Incorporate Eggs & Vanilla. Add the two room‑temperature eggs one at a time, beating briefly after each addition. Follow with the vanilla extract. The eggs act as leaveners, providing lift and structure, while vanilla adds depth to the overall flavor profile.
4. Blend Dry and Wet. Gradually fold the dry flour mixture into the wet ingredients using a spatula. Mix just until you no longer see streaks of flour; over‑mixing would develop gluten, resulting in a tougher cookie.
5. Fold in Chocolate Chips. Gently stir in the semi‑sweet chocolate chips and optional walnuts. Distribute them evenly so each bite contains a satisfying amount of chocolate.
