WHY YOU’LL LOVE THEM
No bake. These bars require no oven — just a microwave or stovetop to melt the butter and marshmallows.
Easy to make. Only five simple ingredients and one mixing bowl make this recipe quick and fuss-free.
Delicious flavor. Crushed Oreos add a rich, crunchy contrast to the soft, chewy Rice Krispie base.
INGREDIENTS
- Salted butter
- Marshmallows
- Oreos — regular stuffed Oreos work best
- Vanilla extract
- Rice Krispie cereal
STEP-BY-STEP INSTRUCTIONS
1. Line an 8×8-inch square baking pan with parchment paper and set aside.
2. Chop 8 regular stuffed Oreos and set them aside.
3. In a large microwave-safe bowl, melt 3 tablespoons of salted butter.
4. Add 30 regular marshmallows to the melted butter and microwave on high for 1½ minutes, stopping to stir after about 45 seconds so they melt evenly.
5. Vigorously stir the melted marshmallows and butter until smooth, then stir in 1 teaspoon of vanilla extract.
6. Add 4 cups of Rice Krispie cereal and the chopped Oreos to the marshmallow mixture. Mix until everything is evenly combined.
7. Transfer the mixture to the prepared pan. Grease your hand or a spatula and press the mixture evenly into the pan. Scatter a few extra Oreo pieces on top if desired.
8. Let the bars cool and set for at least 2 hours, then cut into squares and enjoy.
