Tools I Use For This No-Bake Dessert
- USA Pan 9×13 inch Baking Pan – another USA Pan product I love! The corners of my bars and cakes never stick and I love the squared of edges this pan creates.
- Rubber Spatula – a must have! I like these because they don’t come apart so I don’t have to worry about water getting inside the spatula and causing mold.
- Pyrex Mixing Bowl Set – I love this set of nesting bowls. I use them for everything, Pyrex glass does not break easily so you can trust on these bowls for years, plus they come in 3 useful sizes and can be stacked!
Grocery Store List & Substitutions:
This recipe is made with simple ingredients, many pantry staples you might already have on hand. There are not many substitutions but if there is one, you’ll find it below!

- Unsalted Butter: softened butter works best and melts quickly. Do not substitute margarine or cooking oils.
- Corn syrup: light corn syrup creates a light, chewy consistency and holds the bars together. Honey can be a substitute if needed, but may change the texture slightly.
- Marshmallows: large or mini marshmallows will work, as they melt down completely. I use big marshmallows for the melted mixture and fold in whole mini marshmallows.
- Rice cereal: a must for the classic dessert. Brand name or generic brands will work.

Recipe FAQs
How to keep Rice Krispies form getting hard?
Cooking the marshmallow mixture over medium heat on the stove instead of high will help keep the mixture soft, don’t rush melting the butter and marshmallows. Also, using fresh marshmallows can help – old marshmallows are most likely already a bit hard. Add enough marshmallows, we don’t want to skimp here, this is the only thing adding moisture into the bars.
Can I make Rice Krispies the night before?
Yes! Rice Krispies can be made the day or night before. To keep bars fresh while storing – keep them in an airtight Ziploc bag or glass container at room temperature, layers of parchment paper can be added in between bars to keep them from sticking together.
How many cups of cereal in a box of Rice Krispies?
There are about 10-12 cups of rice Krispies cereal in a box. If making two batches, I would be safe and grab two boxes to have on hand.
