Ingredients

For the blondies:

  • 1/2 cup butter melted
  • 1 cup brown sugar
  • 1 large egg beaten
  • 1 teaspoon vanilla extract
  • 1 cup flour
  • Pinch of salt

For the frosting:

  • 3 tablespoons butter
  • 3 tablespoons milk
  • 1/4 cup granulated sugar
  • 1/3 cup semi-sweet chocolate chips plus more as needed*

Instructions

  • Preheat oven to 350 degrees. Line an 8x8 baking dish with parchment.
  • Add the butter and brown sugar to a medium mixing bowl and stir to combine.
  • Stir in the egg and vanilla.
  • Stir in the flour and salt until well combined.
  • Spread into the prepared pan and bake for 22 minutes or until a tester comes out clean. Cool completely.
  • To make the frosting, put a small saucepan over medium heat.
  • Stir in the butter, milk, and sugar until melted and bring to a full boil.
  • Let boil for exactly 60 seconds and remove from the heat.
  • Stir in 1/3 cup of chocolate chips until melted. Mixture should be pourable, but not super runny. The frosting will thicken up as it cools. If it seems too runny, add an extra tablespoon or two of chocolate chips and stir well until melted into the mixture. Return to heat briefly if needed to melt.
  • Pour the hot frosting over the cooled blondies and allow to set until hardened, about 1 hour.
  • Slice and serve!
