Ingredients

Scale

For the Brown Butter Marshmallow Mixture

  • 5 Tablespoons Butter
  • ¼ teaspoon Vanilla Extract
  • 10 Cups Mini Marshmallows (divided)
  • ½ teaspoon Sea Salt (fine grain)

Other Ingredients

  • 6 Cups Rice Krispies Cereal (cinnamon sugar flavored, see notes)
  • ½ Can Dulce de Leche

Instructions

  1. Prepare the Pan: Spray a 9×9-inch pan with non-stick spray and line it with foil or parchment paper, creating a sling for easy removal. Spray the lining to prevent sticking.
  2. Brown the Butter: Place a large pot over medium heat, add the butter and melt it slowly. Continue cooking it until it turns golden brown and develops a nutty aroma, being careful not to burn it.
  3. Make the Marshmallow Mixture: Remove the pot from heat. Stir in the sea salt and 8 cups of mini marshmallows until fully melted and smooth. If the marshmallows need more melting, briefly return to low heat without burning the butter.
  4. Add Vanilla: Stir the vanilla extract into the smooth browned butter marshmallow mixture for added flavor.
  5. Combine with Rice Krispies: Pour the melted marshmallow mixture over the 6 cups of cinnamon sugar-flavored Rice Krispies in a large bowl. Stir to coat the cereal evenly.
  6. Add Remaining Marshmallows: While the mixture is still warm, fold in the remaining 2 cups of mini marshmallows to add pockets of gooey texture.
  7. Assemble the Treats: Lightly press half of the Rice Krispies mixture evenly into the prepared pan, flattening it carefully. Spread the dulce de leche evenly over this layer.
  8. Top and Set: Spread the remaining Rice Krispies mixture over the dulce de leche layer and press lightly to even out. Allow the treats to cool at room temperature until fully set.

Notes

  • To brown butter, melt it in a pan over medium heat and continue cooking until it develops a golden-brown color and nutty aroma, stirring frequently to prevent burning.
  • For cinnamon sugar-flavored Rice Krispies, you can toss the cereal with a mixture of cinnamon and sugar before adding the marshmallow mixture.
  • Using a foil or parchment sling helps to lift the treats out of the pan easily for cleaner cutting.
  • If the marshmallows begin to harden before assembly, warming them slightly can help keep the mixture pliable.
