If you’ve been invited to a barbecue this weekend, you’re probably thinking about what you can bring. Look no further than the original recipe for Rice Krispies treats.

Every time I’ve had a prepackaged Rice Krispies treat, I’ve been disappointed. They’re often too hard and a little bit stale, which is unfortunate because it’s so easy to make these correctly. You just need the recipe below, and about 20 minutes.

Whether or not you’re headed to a barbecue for summer’s last hurrah, this is a good one to have on file for when you need to contribute to your child’s class party or just want to have an after-school treat on hand.

Ingredients
3 tablespoons unsalted butter
40 marshmallows
6 cups Rice Krispies

Grease a 13-by-9-by-2-inch baking pan with butter. Set aside.

In large saucepan, melt butter over low heat. Add marshmallows and stir until completely melted. Remove from heat.

Add Rice Krispies cereal. Stir until well coated.

Using buttered spatula or wax paper evenly press mixture into pan. Cool. Cut into 2-inch squares. Best if served the same day.
