• Line a 9 x 13 inch rectangular pan with aluminum foil, then lightly butter or spray the inside with baking spray. Set aside. You can also use a non-stick aluminum foil.

Chocolate Rice Krispie Treats Layer

• In a large-size pot over medium heat, melt the unsalted butter, then add in the vanilla extract, and unsweetened cocoa powder.
  4 tbsp Unsalted Butter, 1/4 tsp Vanilla Extract, 1/2 cup Unsweetened Cocoa Powder
• Reduce the heat and add in the mini marshmallows, continuously stirring until fully melted.
  10.5 oz Mini Marshmallows (1 bag)
• Add in the chocolate chips and stir well blended.
  12 oz Milk Chocolate Chips
• Remove from heat and add in the Chocolate Rice Krispies Cereal, stirring until the mixture is fully combined.
  5 cups Chocolate Rice Krispies Cereal
• Scoop the chocolate rice krispie treats mixture into the prepared 9 x 13 inch pan. Press the mixture into the pan using a spatula. Spray the bottom of the spatula with baking spray to keep the mixture from sticking to it.
• Wipe out the pan you just used with a paper towel to use for the next layer.

Marshmallow Layer

• Using the same pot over low heat, melt the unsalted butter and then add in the mini marshmallows. Stir continuously until melted.
  2 tbsp Unsalted Butter, 10.5 oz Mini Marshmallows (1 bag)
• Pour the marshmallow mixture over the chocolate layer, then spread it out using the sprayed spatula.
• You can wipe the large saucepan or pot clean after this step or you can leave it as is since you'll be making the original rice krispie treats layer next.

Original Rice Krispie Treats Layer

• Using the same large-size sauce pan, melt the unsalted butter over medium heat, then add in the vanilla extract and salt.
  8 tbsp 1 stick Unsalted Butter, melted, 2 tsp Vanilla Extract, 1/8 tsp or Pinch of Salt
• Reduce the heat to low and add in 1 1/2 bags of the mini marshmallows, stirring continuously until melted.
  21 oz Mini Marshmallows (2 bags)
• Turn off the heat and add in the rice krispies cereal and stir until the mixture has come together.
  9 cups Rice Krispies Cereal
• Add in the remaining 1/2 bag of mini marshmallows and stir until the mixture is combined, but not the mini marshmallows are not melted. You want to leave them as almost whole mini marshmallows.
• Once combined, take the mixture and scoop it in the prepared 9"x 13" pan over the marshmallow and chocolate layers. Press the mixture into the pan using the sprayed spatula.
• Wait a minimum of 1 hour before cutting them into squares.
