Use cookie cutters to cut out shapes to decorate. Or simply cut out squares, wrap in cellophane bags with ribbon, and sell at your next bake sale.

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.

RICE KRISPIES

You'll need a lot of Rice Krispies cereal, so be sure to buy the family size!

You may also use Cocoa Krispies if you prefer.

equipment you'll need

• Large pot
• Half sheet baking tray (about 12 inches by 18 inches)
• Roasting pan or large bowl
• Non-stick foil
• Non-stick spray

let's make Rice Krispie Treats!

step one: get set up

Line the baking tray with non-stick foil.

Place 10 cups of Rice Krispies cereal in a large bowl or roasting pan that has been coated with non-stick spray.

step two: melt the marshmallows and butter

Cut up 8 tablespoons (1 stick) of salted butter and begin to melt in the large saucepan set over medium-low heat.

Add 20 ounces (about 80 regular OR 12 cups mini) marshmallows.

Stir frequently until most of the marshmallows have melted.

Remove from heat and stir until the mixture is very smooth and the marshmallows are fully melted.

step three: mix it all together

With spatulas that have been sprayed with cooking spray, pour the marshmallow mixture over the cereal and stir very well.

When the mixture is combined, transfer to the baking tray.

Flatten evenly to fill the entire baking tray.

Let set very well, at least an hour.

Cut into squares or cut out shapes with cookie cutters.

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.
