These thick and gooey two-chip chocolate chip cookies are bakery-style perfection — soft in the center, golden at the edges, and loaded with semi-sweet and milk chocolate chips.
1 cup (2 sticks) unsalted butter, softened
¾ cup light brown sugar
½ cup granulated sugar
1 large egg + 1 egg yolk
2 tsp vanilla extract
2¾ cups all-purpose flour
1 tsp baking soda
2 tsp cornstarch
½ tsp salt
1 cup semi-sweet chocolate chips
1 cup milk chocolate chips
Cream butter and sugars until fluffy (2–3 minutes).
Add egg, yolk, and vanilla; mix until smooth.
Combine flour, baking soda, cornstarch, and salt. Add to wet mixture.
Fold in both types of chocolate chips.
Chill dough 1 hour (or overnight for thicker cookies).
Preheat oven to 350°F. Scoop dough into balls and place on parchment-lined trays.
Bake 11–13 minutes, until edges are golden and centers are soft.
Cool 5 minutes on tray before transferring to rack.
Press extra chocolate chips on top before baking for bakery-style presentation.
Store in airtight container for up to 5 days.
Freeze dough balls for fresh-baked cookies anytime.
