- 2 cups puffed rice cereal
- 2 cups miniature marshmallows
- ½ cup chocolate chips (optional, for topping)
- 1 teaspoon vanilla extract (optional, for flavor enhancement)
Step-by-Step Instructions
- Prep the Dish: Start by greasing an 8×8 inch baking pan with a little cooking spray, or line it with parchment paper for easy removal.
- Melt the Ingredients: In a large mixing bowl, combine the peanut butter and honey (or maple syrup). Microwave them in 30-second intervals, stirring between each until melted and smooth.
- Mix in Cereal: Once melted, add the puffed rice cereal to the peanut butter mixture. Stir gently until all cereal pieces are well coated.
- Fold in Marshmallows: Carefully fold in the miniature marshmallows into the mixture. Be gentle, so they don’t melt too much.
- Combine and Press: Pour the mixture into the prepared baking dish, pressing down firmly with a spatula or your hands to create an even layer.
- Top It Off (Optional): If you are using chocolate chips, sprinkle them on top while the mixture is still warm, allowing them to melt slightly and adhere.
- Chill: Let the bars cool at room temperature for about an hour, or pop them into the refrigerator for quicker setting.
- Cut and Serve: Once cooled and set, slice them into squares and serve. Enjoy!
