Step-by-Step Instructions
1. Prepare Your Pan
First, generously grease a 9×13 inch baking pan with butter or cooking spray. This step ensures your five ingredient dessert recipes come out easily. Set it aside for when your mixture is ready.
2. Melt the Butter and Marshmallows
In a large saucepan over low heat, melt the unsalted butter. Once the butter is melted, add the mini marshmallows and stir continuously until they are completely smooth and melted. Be patient, as low heat prevents scorching.
3. Stir in Vanilla and Cereal
Remove the saucepan from the heat. Stir in the vanilla extract until well combined. Now, add the crispy rice cereal to the marshmallow mixture. Mix quickly with a spatula until all the cereal is evenly coated. This is a crucial step for perfectly chewy bars.
4. Press into the Pan
Carefully transfer the mixture into your prepared baking pan. Using a buttered spatula or your lightly buttered hands, gently press the mixture evenly into the pan. Don’t press too firmly, as this can make the bars too dense. If you’re adding sprinkles, scatter them over the top now and press them in slightly.
5. Cool and Cut
Allow the bars to cool completely at room temperature, which usually takes about 30-45 minutes. Once cooled, use a sharp knife to cut them into 12 equal bars. Now you have a wonderful addition to your collection of five ingredient dessert recipes!
Variation Ideas
- Chocolate Drizzle: Melt chocolate chips and drizzle over cooled bars.
- Nutty Bars: Add chopped peanuts or almonds to the cereal mixture.
- Fruity Fun: Use a fruity-flavored crispy cereal for a different taste.
- Holiday Themed: Use seasonal sprinkles and food coloring in the marshmallow mixture for festive treats.
- S’mores Style: Mix in graham cracker crumbs and chocolate chips, then top with toasted mini marshmallows.
Storage Instructions
Store your Marshmallow Cereal Bars in an airtight container at room temperature for up to 3 days. To keep them fresh longer, you can wrap individual bars in plastic wrap. Avoid refrigeration, as it can make them hard and less chewy.
