- Parchment paper
- Oven
Ingredients
For the Cookie Dough
- 1 cup unsalted butter melted
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 eggs
- 2 teaspoons vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
Mix-Ins & Toppings
- 1 cup butterscotch chips divided
- 1 cup toffee bits divided
- 1/2 cup white chocolate chips optional
Instructions
- Preheat oven to 350°F. Line a 9×13-inch pan with parchment paper and lightly spray with nonstick spray.
- In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth and glossy.
- Add eggs one at a time, mixing well after each. Stir in vanilla extract.
- Sprinkle flour, baking soda, and salt over wet mixture. Fold gently until just combined.
- Fold in ¾ of the butterscotch chips and toffee bits (and white chocolate chips, if using).
- Spread dough evenly into prepared pan. Press remaining butterscotch chips and toffee bits on top.
- Bake 22–25 minutes until edges are golden but center looks slightly underbaked. Do not overbake.
- Cool completely in pan on a wire rack. For clean cuts, refrigerate for 30 minutes before slicing.
Notes
For extra depth, brown the butter before using. Freeze toffee bits before baking to prevent them melting completely. Sprinkle with flaky sea salt after baking for a gourmet touch.
