Ingredients

Scale

Wet Ingredients

  • 1 cup unsalted butter, melted
  • 1 ½ cups packed brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract

Dry Ingredients

  • 2 cups all-purpose flour, spooned and leveled
  • 1 teaspoon baking soda
  • ½ teaspoon salt

Mix-ins

  • 1 cup butterscotch chips
  • 1 cup toffee bits

Instructions

  1. Preheat: Preheat your oven to 350°F (175°C) to prepare for baking the cookie bars.
  2. Mix wet ingredients: In a large bowl, blend together the melted unsalted butter and packed brown sugar until creamy and well combined, releasing a rich aroma.
  3. Add eggs and vanilla: Stir in the room temperature eggs and pure vanilla extract until the mixture is smooth and glossy, forming the flavorful base for the bars.
  4. Whisk dry ingredients: In a separate bowl, combine the all-purpose flour, baking soda, and salt to ensure proper rising and flavor balance.
  5. Combine mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just incorporated to avoid overmixing and resulting toughness.
  6. Fold in chips and toffee: Gently fold in the butterscotch chips and toffee bits to evenly distribute flavor and texture.
  7. Scoop dough: Drop rounded tablespoons of the dough onto a lined baking sheet, spacing them to allow spreading during baking.
  8. Bake: Bake in the preheated oven for 10-12 minutes or until the edges are golden brown while the centers remain soft and chewy.
  9. Cool: Allow the cookie bars to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely for the best texture and flavor.

Notes

  • For extra chewyness, chill the dough for 30 minutes before baking; this improves texture significantly.
  • Use cooled melted butter to avoid cooking the eggs, maintaining softness.
  • Do not overmix the batter to prevent tough cookie bars.
  • You can substitute coconut oil for butter for a dairy-free version.
  • Replace all-purpose flour with a 1:1 gluten-free blend for gluten-free bars.
  • For additional texture, fold in chopped nuts like walnuts or pecans.
  • Experiment with half chocolate chips in place of butterscotch chips for a chocolate twist.
  • Check for doneness by ensuring the edges are golden while centers remain soft for optimal chewiness.
