how to make a big batch of Rice Krispie Treats

Because you're working with a larger amount of ingredients, it's best to make these treats on the stove-top, rather than the microwave.

TIPS:

Use a large saucepan or stock pot to melt the marshmallows and butter.
Instead of a large bowl, I mixed the Rice Krispie treats and marshmallow mixture in my roasting pan!

ingredients you'll need

BUTTER

We suggest salted, European-style butter for best flavor.

MARSHMALLOWS

My preferred brand of marshmallows is Jet Puffed. I use the regular size, but you may also use the mini.

Different brands have different densities and weights, so be sure to check out our marshmallow conversion guide.

How do I color Rice Krispie Treats?

If you're making decorated Rice Krispie Treats and want to add color, it's easy!

I added coloring to make shamrock cereal treats or emoji treats.

To color your treats, stir gel paste food coloring into your smooth, melted marshmallow and butter mixture, BEFORE adding to the cereal.
