Ingredients

Scale

Main Ingredients

  • 4 cups marshmallows (fresh for best results)
  • 6 cups crispy rice cereal
  • 1/2 cup (1 stick) butter
  • 1/4 cup brown sugar, packed
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour (or gluten-free flour for gluten-free version)
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Instructions

  1. Prepare your ingredients: Gather all ingredients and measure carefully. Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone mat for easy cleanup.
  2. Melt the butter and marshmallows: In a large saucepan over low heat, gently melt the butter. Once melted, add the marshmallows and stir continuously until completely melted and smooth to create a luscious, sticky marshmallow base.
  3. Stir in sugar and vanilla: Remove the saucepan from heat. Mix in the brown sugar until fully combined, then add vanilla extract. This step enhances the sweetness and infuses lovely flavor notes into your mixture.
  4. Combine dry ingredients separately: In a medium bowl, whisk together the flour, baking soda, and salt to ensure an even distribution of leavening agents and seasoning.
  5. Mix dry ingredients into marshmallow mixture: Gradually fold the dry ingredients into the warm marshmallow mixture, stirring constantly to avoid lumps. This forms a soft dough that will hold the crispy cereal and marshmallow magic.
  6. Add crispy rice cereal and fold gently: Carefully fold in the crispy rice cereal until evenly incorporated, making sure to keep the cereal intact for maximum crunch and that signature texture.
  7. Scoop and bake: Drop spoonfuls of the cookie mixture onto the prepared baking sheet, spaced evenly. Bake for 10-12 minutes or until golden around the edges but still soft in the center, for a perfectly chewy and gooey cookie.
  8. Cool and enjoy: Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This helps them set and keeps their lovely chewy texture.

Notes

  • Use fresh marshmallows for even melting and ideal gooey texture.
  • Don’t overbake; remove cookies as soon as edges turn golden to maintain softness inside.
  • Line your baking pan with parchment paper to prevent sticking and make cleanup easy.
  • Allow cookies to cool slightly on the baking sheet to set without losing moisture.
  • Store cookies in airtight containers at room temperature to keep them soft and delicious for up to 4 days.
