  • Total Time: 32 minutes
  • Yield: 24 bars

Ingredients

Wet Ingredients

  • ½ cup unsalted butter
  • 1 cup butterscotch chips
  • ⅔ cup light brown sugar, packed
  • 2 large eggs
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 ½ cups all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon kosher salt

Mix-ins

  • 2 cups mini marshmallows
  • 1 cup semi-sweet chocolate morsels

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 13×9-inch baking dish with parchment paper to prevent sticking.
  2. Melt Butterscotch Chips and Butter: In a small bowl, melt the butterscotch chips together with the unsalted butter by microwaving in 30-second increments, stirring between each, until fully melted. Set aside to cool slightly.
  3. Mix Wet Ingredients: In a large mixing bowl, combine the light brown sugar, eggs, and vanilla extract. Mix well until smooth.
  4. Incorporate Melted Butterscotch Mixture: Add the melted butterscotch and butter mixture into the sugar and egg mixture, stirring to combine fully.
  5. Add Dry Ingredients: Gradually mix in the all-purpose flour, baking powder, and kosher salt. Stir until just combined to avoid overmixing.
  6. Fold in Mix-ins: Gently fold the mini marshmallows and semi-sweet chocolate chips into the batter, distributing them evenly.
  7. Pour Batter and Bake: Pour the batter into the prepared baking dish, smoothing the top evenly. Bake in the preheated oven for 18-22 minutes or until edges are golden and a toothpick inserted near the center comes out clean or with a few moist crumbs.
  8. Cool and Chill: Allow the bars to cool completely in the pan. Once cooled, cut into 24 squares and refrigerate for one hour to set and enhance the flavor and texture.
  9. Serve and Enjoy: Serve chilled bars for the best chewy, gooey experience.

Notes

  • Parchment Paper: Use parchment paper to line your baking pan to prevent sticking. Avoid foil or wax paper as they do not yield the same results.
  • Storage: Store bars in an airtight container at room temperature if consuming within a day, but they taste best when chilled.
  • Freezing: To freeze, wrap bars tightly in plastic wrap and place in a freezer-safe zipper or airtight container for up to 3 months.
  • Substitutions: Substitute butterscotch chips with peanut butter morsels for a different but delicious twist.
  • Tips: See the blog post for additional recipe tips and tricks to perfect your bars.
