Ingredients Equipment Method Notes

Ingredients
  

  • 4 cups large marshmallows preferably fresh and soft
  • 3 tablespoons butter salted or unsalted
  • 3 cups graham cracker crumbs crushed into coarse crumbs
  • 0.5 cups semi-sweet chocolate chips melted for drizzling (optional)

Equipment

  • 9x13 inch pan
  • Large mixing bowl
  • Spatula
  • Microwave-safe bowl
  • Parchment paper or butter

Method
 

  1. Line your 9x13 inch pan with parchment paper or lightly butter it to prevent sticking.
  2. Combine the marshmallows and butter in a microwave-safe bowl and microwave in 30-second bursts, stirring each time, until the mixture is smooth and bubbly — about 1 to 2 minutes total.
  3. Add the crushed graham crackers to the melted marshmallow mixture and gently fold until all the crumbs are coated and evenly distributed, creating a sticky, gooey mass.
  4. Pour the mixture into your prepared pan, then press it down firmly with the back of a spatula or wax paper to create an even layer — compacting it well helps the bars hold together.
  5. If you like, melt the semi-sweet chocolate chips and drizzle or spread a thin layer over the top for extra richness and visual appeal.
  6. Let the bars sit at room temperature for about 30 minutes, or refrigerate for 15-20 minutes until they are firm and set.
  7. Once cooled, use a sharp knife to cut into squares or rectangles. Press down firmly when slicing to prevent crumbling.
  8. Serve immediately or store in an airtight container at room temperature for up to 3 days. Enjoy these chewy, gooey treats!

Notes

For an extra crunch, add chopped nuts or dried fruit into the mixture before pressing into the pan. To make these vegan, substitute vegan marshmallows and dairy-free butter. Customize with your favorite chocolate or add a sprinkle of sea salt for enhanced flavor.
