Soft, thick, bakery-style cookies inspired by Crumbl — rich, chewy, and endlessly customizable with your favorite fillings and frostings.
1 cup unsalted butter, softened
¾ cup brown sugar
½ cup granulated sugar
2 large eggs
1 egg yolk
2 tsp vanilla extract
3½ cups all-purpose flour
2 tsp cornstarch
1 tsp baking soda
½ tsp baking powder
¾ tsp salt
1½ cups chocolate chips (or mix-ins of choice)
Preheat oven to 375°F. Line baking sheets with parchment.
Cream butter and sugars until fluffy.
Beat in eggs, yolk, and vanilla.
Whisk dry ingredients in a separate bowl. Mix into wet just until combined.
Fold in chocolate chips. Chill dough 15–30 min.
Scoop into large balls (¼ cup each), place on baking sheet, and flatten tops slightly.
Bake 10–12 min until edges are golden. Cool before topping or serving.
Top with frosting, sprinkles, or fillings to match Crumbl flavors. Freeze dough or baked cookies for later.
