# The Ingredients You'll Need:
→ Base
01 - 6 tablespoons unsalted butter, plus extra for greasing
02 - 10 ounces mini marshmallows
03 - 6 cups Rice Krispies cereal
04 - ¼ teaspoon fine sea salt, optional
→ Chocolate Topping
05 - 1½ cups semisweet or dark chocolate chips
06 - 1 teaspoon vegetable oil or coconut oil
→ Garnish
07 - 2 tablespoons rainbow sprinkles or chopped nuts, optional
# Step-by-Step Instructions:
01 - Lightly grease an 8x8-inch or 9x9-inch square baking pan with butter.
02 - In a large saucepan over low heat, melt the butter, stirring constantly to prevent browning.
03 - Add mini marshmallows and continue stirring until completely melted and smooth.
04 - Remove from heat and stir in sea salt if using.
05 - Add Rice Krispies cereal and gently fold with a spatula until evenly coated.
06 - Transfer the mixture to the prepared pan. Using a buttered spatula or hands, press the mixture evenly and firmly into the pan.
07 - Let sit at room temperature for about 10 minutes.
08 - In a microwave-safe bowl, combine chocolate chips and oil. Microwave on medium power in 30-second intervals, stirring after each, until melted and glossy.
09 - Pour the melted chocolate over the cooled Rice Krispy layer. Spread evenly with an offset spatula or the back of a spoon.
10 - Immediately sprinkle with rainbow sprinkles or chopped nuts if desired.
11 - Allow the treats to set at room temperature for at least 1 hour, or refrigerate for 20–30 minutes until the chocolate is firm.
12 - Once set, lift the block from the pan using parchment overhang if used or invert onto a cutting board. Cut into 12–16 bars with a sharp knife.
