Frequently Asked Questions

What to Serve with Rice Krispies Treats

These Rice Krispie treats are great served on their own or can be served with a little frosting and some sprinkles!

Can I Make These in the Microwave?

Rice Krispies Treats can also be made in the microwave. To make in the microwave, microwave the butter until melted and set aside (about 45 seconds). In a separate microwave safe bowl, microwave the marshmallows for 2-3 minutes, stirring every 30 seconds, until melted. Once melted, add in the butter and follow the regular recipe.

It’s super important to stir the marshmallows often or else they can become overcooked and result in hard Rice Krispies treats.

Can you Freeze Leftovers?

Yes! Extra Rice Krispies treats can be frozen for up to 6 months. I like to wrap them individually in plastic wrap and then place in a freezer bag.

When you’re ready to serve, defrost by putting in the fridge 24 hours before you plan to eat them.
