Equipment

Ingredients

  • 8 tablespoons unsalted butter melted & slightly cooled
  • 1 cup light brown sugar gently packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1 cup flour
  • 1 cup white chocolate chips divided

US - Metric

Instructions

  • Preheat oven to 350°F (175°C). Spray an 8 x 8-inch pan with cooking spray and line with parchment paper, leaving an overhang for easy removal.
  • Melt the butter in a microwave-safe bowl. Let cool for about 5 minutes.
  • Scrape all of the melted butter into a large bowl. Add the brown sugar and whisk until the mixture looks like wet sand. Add the egg, vanilla, and salt and whisk briskly until smooth and creamy. Fold in the flour and 3/4 cup white chocolate chips with a spatula until no dry streaks remain. The batter will be thick.
  • Transfer the batter to the prepared pan and smooth the top with a spatula.
  • Bake for 25 to 27 minutes, or until the edges are lightly golden and the center is set.
  • Sprinkle the marshmallows over the top and gently press them into the bars. Return the pan to the oven for 1 minute.
  • Remove from the oven and gently press the marshmallows down so they stick. Immediately sprinkle the remaining 1/4 cup white chocolate chips, M&M’s, and sprinkles over the top.
  • Let the bars sit for 1 to 2 hours before cutting.
