Ingredients Equipment Method Notes

Ingredients
  

  • 1/4 cup unsalted butter
  • 4 cups mini marshmallows
  • 1 teaspoon vanilla extract
  • 2 cups graham crackers crushed
  • 1/2 cup chocolate chips semi-sweet preferred
  • a pinch sea salt optional, for flavor

Equipment

  • 20x20 cm (8x8 inch) pan
  • Spatula or butter knife
  • Microwave-safe bowl

Method
 

  1. Place the unsalted butter in a microwave-safe bowl and microwave on high for about 30 seconds until melted and fragrant.
  2. Add the mini marshmallows to the melted butter and microwave in 20-second bursts, stirring each time, until completely melted and smooth. The mixture should be bubbling and glossy.
  3. Stir in the vanilla extract and a pinch of sea salt into the marshmallow mixture. The aroma should be sweet and fragrant, and the mixture will be thick and shiny.
  4. Gently fold in the crushed graham crackers until evenly coated and sticky, creating a textured, dough-like mixture.
  5. Transfer the mixture into your prepared pan and press it firmly with a spatula or butter knife to create an even layer. Press down until the mixture feels compact and smooth on top.
  6. Sprinkle the chocolate chips evenly over the surface and gently press them in so they slightly melt into the top layer, adding a glossy, decadent appearance.
  7. Let the bars set at room temperature for about 30 minutes, or refrigerate for 15-20 minutes if you prefer a firmer texture. The mixture should be firm enough to cut cleanly.
  8. Use a sharp knife to cut into squares, wiping the blade between cuts for neat edges. The bars are ready to serve once fully set and firm.
  9. Enjoy these gooey, crunchy bars immediately or store in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly and refrigerate or freeze for up to a month.

Notes

For extra crunch, fold in nuts or dried fruit before pressing into the pan. To make them vegan, use plant-based butter and vegan marshmallows.
