Ingredients

  • ½ cup unsalted butter
  • 1 cup light brown sugar packed
  • 2 ½ teaspoon vanilla extract
  • 1 egg
  • 1 cup all-purpose flour
  • pinch salt
  • 1 cup butterscotch chips
  • ½ cup toffee bits

Instructions

  • Preheat oven to 350°F. Line an 8x8 baking pan with parchment paper and set aside.
  • In a small saucepan, brown butter until it is a golden brown color. Once it is brown enough, pour into a large bowl, being sure to scrape the brown bits at the bottom of the pan. Stir in brown sugar until smooth. Add in egg and vanilla until combined. Add flour and mix until just combined.
  • Reserve 1 tbs each of butterscotch chips and toffee bits and fold in the remaining amounts until evenly distributed.
  • Spread mixture into prepared baking pan into an even layer. Sprinkle the reserved mix-ins and press them down a bit so they stay in place.
  • Bake for 20-23 minutes or until a toothpick inserted in the center comes out with a few moist crumbs on it. They will appear under baked, but they will continue to bake in the hot pan when they are taken out.
  • Allow them to cool in pan for 10 minutes before transferring to a wire rack to finish. Once they're firm enough to cut, slice them into bars and enjoy.

Notes

Storage instructions: These butterscotch blondies will stay fresh for up to 5 days stored at room temperature in an airtight container.
Freezing instructions: To freeze, wrap bars individually or the whole thing before cutting in a layer of plastic wrap. Then wrap in a layer of foil and place in a resealable, freezer-safe bag. Freeze for up to 3 months. Thaw at room temperature.
