• Lightly butter or spray with nonstick spray a 9 x 13 baking dish and set it aside.
• In a large saucepan, melt the butter over low heat.Add the mini marshmallows to the melted butter. Stir continuously until the marshmallows are completely melted and the mixture is smooth.
• Remove the pan from heat. Immediately stir in the chocolate Rice Krispies cereal, mixing until the cereal is evenly coated with the marshmallow mixture.
• Transfer the mixture to the prepared baking dish. Using a buttered spatula or lightly greased hands, gently press the mixture into an even layer. Do not press too firmly, or the treats will be dense.
• Let the treats cool for about 10–15 minutes cools and sets.

Adding optional Chocolate Drizzle & Sprinkles

• Place the chocolate frosting in a microwave-safe bowl. Heat in 10–15 second intervals, stirring between each, until melted and smooth.
• Transfer the melted frosting to a zip-top bag. Snip a small corner and drizzle the chocolate evenly over the treats.Immediately sprinkle chocolate sprinkles over the drizzle before it sets.
• Allow the treats to cool completely, then cut into squares and serve. Chocolate drizzle and chocolate sprinkles on chocolate cereal squares are so delightful!!
