Ingredients

Scale
  • 3 cups Rice Krispies cereal (or any crispy rice cereal)
  • 1 1/2 cups mini marshmallows (plus extra for topping, if desired)
  • 2 tablespoons unsalted butter
  • 1/4 teaspoon fine sea salt
  • 1/2 teaspoon vanilla extract
  • 1 1/4 cups semi-sweet chocolate chips (milk or dark chocolate chips work too)
  • 1/2 cup creamy peanut butter
  • 1 tablespoon coconut oil (or vegetable oil)
  • 4 graham crackers, crushed (about 1/2 cup)
  • Pinch of flaky sea salt (optional, for topping)
  • Extra mini marshmallows, white chocolate drizzle, chopped peanuts, or mini chocolate chips for garnish (optional)

Instructions

  1. Line a 12-cup standard muffin tin with cupcake liners or use silicone molds on a baking sheet.
  2. In a medium saucepan, melt butter over low heat. Add mini marshmallows and stir constantly until melted and smooth, about 2-3 minutes.
  3. Remove from heat and stir in salt and vanilla extract. Immediately add Rice Krispies cereal and mix until fully coated.
  4. Divide the cereal mixture evenly among the muffin cups (about 2 packed tablespoons per cup). Press down gently with greased fingers or the back of a spoon.
  5. Sprinkle a generous teaspoon of crushed graham crackers over each Rice Krispie layer, pressing gently so the crumbs stick.
  6. In a microwave-safe bowl, combine chocolate chips, peanut butter, and coconut oil. Microwave in 30-second intervals, stirring after each, until melted and smooth (about 1-1.5 minutes total). Alternatively, melt together in a double boiler.
  7. Spoon about 2 tablespoons of the chocolate-peanut butter mixture over each cup, covering the cereal and graham layer. Smooth the tops with a spatula or spoon.
  8. While the chocolate is still soft, add desired toppings: flaky sea salt, extra mini marshmallows, chopped peanuts, mini chocolate chips, or a drizzle of white chocolate.
  9. Chill the muffin tin in the refrigerator for at least 1 hour, or until the chocolate is set. (Speed up in the freezer for about 25 minutes if desired.)
  10. Once set, lift each cup out of the tin using the liners. Peel back the paper and enjoy! If not using liners, run a warm butter knife around the edges to help release.

Notes

Work quickly with the marshmallow mixture as it sets fast. Grease your hands or spatula to prevent sticking. For gluten-free or vegan versions, use appropriate substitutions for cereal, graham crackers, marshmallows, and chocolate. Chill thoroughly for clean layers. Store in an airtight container in the fridge for up to 5 days or freeze for up to 2 months.
