Ingredients

Scale

Wet Ingredients

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

Dry Ingredients

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon kosher salt

Add-ins

  • 1 cup butterscotch baking chips
  • 3/4 cup toffee bits

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (177°C). Prepare a 9×13-inch baking pan by lining it with parchment paper, allowing the edges to overhang for easy removal later.
  2. Mix Butter and Sugar: In a large bowl, whisk together the melted unsalted butter and packed brown sugar until the mixture is smooth and glossy, ensuring the sugar is well incorporated.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time, mixing thoroughly after each addition. Then blend in the pure vanilla extract until the mixture is fully combined.
  4. Combine Dry Ingredients: Sift together the all-purpose flour, baking powder, and kosher salt. Gradually fold this dry mixture into the wet ingredients gently to avoid overmixing, which keeps the bars tender.
  5. Stir in Add-ins: Fold in the butterscotch baking chips and toffee bits evenly throughout the batter to distribute the sweet, crunchy elements.
  6. Transfer and Smooth Batter: Pour the batter into the prepared baking pan and smooth the surface with a spatula for even baking.
  7. Bake: Bake in the preheated oven for 25 to 30 minutes until the edges turn golden brown and the center is just set, achieving a chewy texture.
  8. Cool and Cut: Allow the bars to cool completely in the pan. Use the parchment paper overhang to carefully lift the bars out, then cut them into squares for serving.

Notes

  • Do not overbake the bars to maintain their chewy texture.
  • For cleaner edges when cutting, chill the bars in the refrigerator before slicing.
  • Store bars in an airtight container at room temperature for up to four days.
  • You can freeze the bars wrapped tightly for up to two months for longer storage.
