3-Ingredient Rice Krispie Treats
You only need three things for these treats: cereal, marshmallows, and butter. That’s it.
No corn syrup, no vanilla extract, no fancy additions. Just the basics that work perfectly together.
Marshmallow Quality Makes Everything
Fresh marshmallows melt smoothly and create that perfect chewy texture. Stale ones turn grainy and won’t bind properly. Check the bag date and give them a squeeze – they should feel soft and springy, not hard or dried out.

Must-Have Items
Low Heat Prevents Disaster
Melt everything over low heat only. High heat turns marshmallows into cement-hard candy that won’t mix with the cereal. You want them just melted, not bubbling or browning. Stir constantly and remove from heat the moment they’re smooth.
Press Gently Into Pan
Don’t pack these down hard or you’ll get dense, tough squares. Use buttered hands or wax paper to press just enough so they hold together. The lighter your touch, the more tender your final treats will be.
Avoiding the Sticky Mess
- Butter your hands before pressing the mixture into the pan to prevent everything from sticking to your fingers.
- Cut with a sharp knife dipped in warm water between cuts for clean edges that don’t tear.
Frequently Asked Questions
Will regular marshmallows work instead of mini ones?
Yes, but cut them into smaller pieces first. Large marshmallows take longer to melt evenly and can create hot spots.
How long do these stay fresh?
Store covered at room temperature for up to one week. They’ll get slightly firmer after day three but still taste great.
Should I refrigerate them to set faster?
Skip the fridge – it makes them too hard. Room temperature setting gives you the perfect chewy texture you want.
