Description

Fudgy chocolate brownie bars topped with soft marshmallows, glossy strawberry preserves, and fresh diced strawberries for a rich, fruity dessert.


Ingredients

Scale
  • 1/2 cup unsalted butter, melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 cup semi-sweet chocolate chips
  • 2 cups mini marshmallows
  • 3/4 cup strawberry preserves, warmed slightly
  • 1/2 cup fresh strawberries, diced small

Instructions

  1. Preheat the oven to 350°F and line an 8-inch square baking pan with parchment paper.
  2. Whisk the melted butter and sugar in a mixing bowl until smooth.
  3. Add the eggs and vanilla extract, then whisk until fully combined.
  4. Stir in the cocoa powder, all-purpose flour, and salt until just combined.
  5. Fold in the semi-sweet chocolate chips.
  6. Spread the brownie batter evenly into the prepared baking pan.
  7. Bake for 22 minutes, until the brownie base is mostly set.
  8. Remove the pan from the oven and sprinkle the mini marshmallows evenly over the top.
  9. Return the pan to the oven and bake for 4 minutes, just until the marshmallows soften.
  10. Warm the strawberry preserves slightly, then gently spread them over the softened marshmallows.
  11. Scatter the diced strawberries over the top.
  12. Cool completely, then chill for 30 minutes for cleaner slices.
  13. Lift from the pan, slice into 12 bars, and serve.

Notes

  • Let the bars cool fully before slicing so the marshmallow layer sets properly.
  • Clean the knife between cuts for neater squares.
  • Use raspberry or cherry preserves for a simple flavor variation.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
