IngredientsTo prepare Marshmallow Chocolate Squares, you will need the following ingredients:

  • 1/2 cup (1 stick) unsalted butter
  • 1 package (about 10 oz) of marshmallows
  • 6 cups crispy rice cereal
  • 2 cups semisweet chocolate chips
  • 1 teaspoon vanilla extract
  • A pinch of salt (optional)


1. Preparing the Base: In a large saucepan, melt the unsalted butter over low heat. Add the marshmallows and stir until they are completely melted and the mixture is smooth. If desired, add a pinch of salt to enhance the flavor.

2. Adding Crispy Rice Cereal: Remove the saucepan from heat and gently fold in the crispy rice cereal, ensuring it’s well-coated with the marshmallow mixture. This will create the base of your Marshmallow Chocolate Squares.

3. Pressing into a Pan: Transfer the mixture to a greased 9×13-inch baking pan. Use a spatula or wax paper to press it down firmly and evenly. Let it cool while you prepare the chocolate topping.

4. Preparing the Chocolate Layer: In a microwave-safe bowl, heat the semisweet chocolate chips in 30-second intervals, stirring after each interval, until they are fully melted and smooth. Stir in the vanilla extract.

5. Layering the Chocolate: Spread the melted chocolate evenly over the cooled marshmallow and cereal base in the baking pan. You can use a spatula or the back of a spoon to achieve a smooth layer.

6. Cooling and Cutting: Allow the Marshmallow Chocolate Squares to cool for several hours or refrigerate them for about an hour to set the chocolate. Once the squares are firm, use a sharp knife to cut them into your desired serving size.

Cooking Notes When making Marshmallow Chocolate Squares, it’s essential to melt the marshmallows gently over low heat to prevent scorching. You can also add a pinch of salt to the marshmallow mixture to balance the sweetness. When pressing the mixture into the pan, you may find it helpful to grease your hands or the spatula to prevent sticking.


While the classic Marshmallow Chocolate Squares are timeless, there are creative variations you can explore:

  1. Peanut Butter Bliss: Incorporate peanut butter into the chocolate topping for a delightful twist. Simply mix 1/2 cup of peanut butter with the melted chocolate chips.
