Ingredients
  

Base Ingredients
  • 5 Tablespoons Butter Use unsalted butter for better control of salt.
  • ¼ teaspoon Vanilla Extract Pure vanilla extract is preferred.
  • 10 Cups Mini Marshmallows (divided) Reserve 2 cups for mixing in later.
  • 6 Cups Rice Krispies Cereal (cinnamon sugar flavored) You can substitute with plain Rice Krispies.
  • ½ teaspoon Sea Salt (fine grain) Enhances flavor.
  • ½ Can Dulce de Leche Can be warmed slightly if too thick.

Method
 

Preparation
  1. Spray a 9×9-inch pan with non-stick spray and line it with foil or parchment paper, then spray again.
  2. In a large pot over medium heat, add the butter and let it melt and brown, stirring occasionally.
  3. Once browned, remove from heat, add the salt and 8 cups of mini marshmallows. Stir until fully melted and smooth.
  4. Add vanilla extract and stir again.
  5. In a large bowl, measure out the Rice Krispies cereal. Pour the melted marshmallows over the cereal and mix well.
  6. Add the remaining marshmallows while the mixture is still warm.
Assembly
  1. Lightly press half of the mixture into the prepared pan, ensuring it is even.
  2. Spread the dulce de leche evenly over the mixture.
  3. Top with the remaining rice krispies mixture and press it down to ensure even distribution.
  4. Let it set at room temperature until cooled.

Notes

For the best flavor and texture, allow bars to come to room temperature before cutting. Sprinkle flaky sea salt on top before serving for added flavor.
