Ingredients

• ¼ cup + 1 tablespoon vegan butter

• 15 ounces vegan mini marshmallows

• ¾ cup creamy peanut butter

• 6 cups rice krispies cereal

Directions

1. Prep the pan: Line a 9x13-inch baking dish with parchment paper or lightly grease with oil.

2. Melt the butter: In a large pot over low heat, melt the vegan butter.

3. Add marshmallows: Once melted, add the vegan marshmallows and stir constantly as they begin to melt.

4. Mix in peanut butter: When the marshmallows are partially melted, add the peanut butter. Continue stirring until the mixture becomes thick and smooth—about 5 minutes.

5. Add the cereal: Remove from heat and quickly stir in the rice krispies. Mix until fully coated and evenly combined.

6. Press into the pan: Transfer the mixture to the prepared baking dish. Use a spatula or clean hands to press it down firmly and evenly.

7. Cool and set: Let the treats cool at room temperature for at least 1 hour to firm up.

8. Cut and serve: Remove from the pan and cut into squares or bars of your desired size.

FAQs

Can I use regular marshmallows?

Yes, if you’re not vegan, regular marshmallows work just fine in the same quantity.

Are Rice Krispies vegan?

Not all are—check the label for vitamin D3 or gelatin, which aren’t vegan. Use a vegan-certified brand.

Can I make these without peanut butter?

Yes! Try almond butter, cashew butter, or sunflower seed butter as a substitute.

What if my marshmallows don’t fully melt?

It’s okay—your treats will just have some gooey bits of mallow throughout.

Why are my treats too hard?

This usually happens from cooking the mixture on too high heat. Always melt ingredients slowly over low heat.

Can I reduce the sugar?

You can try using fewer marshmallows or less peanut butter, but texture and sweetness may be affected.

Can I add chocolate?

Yes! Stir in mini vegan chocolate chips or top with melted chocolate for a peanut butter cup-style bar.

Do I need to refrigerate them?

No, but refrigerating can help them set faster or store longer.

Can I make these gluten-free?

Yes—just make sure your rice cereal is labeled gluten-free.

Can I use chunky peanut butter?

Absolutely! It adds extra texture and crunch.
