Step-by-Step Instructions

1. Prepare the Base

In a large mixing bowl, combine the crispy rice cereal and powdered sugar. Stir well to evenly coat the cereal and prevent clumping later.

2. Melt and Mix

In a saucepan over low heat, add the peanut butter and melted butter. Stir continuously until smooth and fully combined. Remove from heat and stir in the vanilla extract.

3. Combine Everything

Pour the warm peanut butter mixture over the cereal mixture. Gently fold until all the cereal is evenly coated. While the mixture is still warm, fold in the mini marshmallows, allowing some to slightly melt for extra gooeyness.

4. Shape the Cups

Line a muffin tin with paper liners. Spoon the mixture evenly into each cup, pressing gently with the back of a spoon to help them hold their shape.

5. Chill and Set

Place the muffin tin in the refrigerator for at least 30 minutes, or until the cups are firm and set.

6. Serve and Enjoy

Once set, remove from the liners and enjoy immediately, or store for later.

Tips for Perfect Peanut Butter Marshmallow Cups

• Use creamy peanut butter for the smoothest texture and easiest mixing.
• Work quickly once the peanut butter mixture is warm so the marshmallows incorporate evenly.
• Lightly greasing your spoon helps prevent sticking when pressing the mixture into the cups.
• For cleaner edges, chill thoroughly before removing from the liners.

Frequently Asked Questions

Can I make Peanut Butter Marshmallow Cups ahead of time?

Absolutely. These cups are ideal for making ahead because they hold their shape and flavor very well. Once fully set, store them in an airtight container in the refrigerator for up to five days. If you’re preparing them for an event, making them the night before ensures the perfect texture and saves you time on the day of serving.

Do these cups need to be refrigerated at all times?

Refrigeration helps the cups stay firm, especially in warm environments. While they can sit at room temperature for a short period during serving, keeping them chilled will maintain their structure and prevent them from becoming too soft. For best results, return leftovers to the refrigerator promptly.

Can I adjust the sweetness level of this recipe?

Yes, the sweetness can be adjusted easily. If you prefer a less sweet treat, slightly reduce the powdered sugar or use a peanut butter with no added sugar. The marshmallows provide plenty of sweetness on their own, so small adjustments won’t affect the texture.

Are Peanut Butter Marshmallow Cups kid-friendly?

These treats are extremely popular with kids due to their soft texture and familiar flavors. They’re easy to hold, not messy, and perfect for lunchboxes or after-school snacks. You can even involve kids in the preparation since there’s no baking involved, making it a fun and safe kitchen activity.
