Rice Krispie Treats Ingredients

CEREAL: Rice Krispies are the classic base for this sweet treat, but cocoa Krispies, toasted O’s, Chex, even Lucky Charms are yummy swaps! 

MARSHMALLOWS: Choose mini marshmallows because they’ll melt faster, or cut large marshmallows (approximately 50 each) into smaller pieces. Multi-colored marshmallows are a fun, colorful substitute and will be just as chewy and gooey!

BUTTER: For best results, use real butter to get that rich, buttery sweet flavor. Swirl in some peanut butter with the marshmallows for an even yummier treat!

Variations

  • This is the fun part! Mini M&M’s, chocolate chips, toffee pieces, crushed Oreo pieces, even chopped, dried fruit like cherries, apricots, or mangoes can be added to rice Krispie squares!

How to Make Rice Krispie Treats in the Microwave

Microwaveable treats are super fun and easy to make:

  1. Place butter and marshmallows in a microwave-safe bowl. Heat (per recipe instructions below).
  2. Once the mixture is melted and smooth, add vanilla & gently stir in the cereal.
  3. Press mixture into a pan and cool before cutting into desired sizes.

PRO TIP: Pour all of the cereal into a colander to shake out the ‘cereal dust’ before mixing into the marshmallow mixture).

Time Savers

  • Chop refrigerated butter into small pieces so it melts faster. 
  • If adding nut butter, microwave the jar for about 30 seconds to make it easier to spoon into the mixture. 
  • To shorten microwave melting time, 1 ½ jars (10 oz) of marshmallow crème (or fluff), can be substituted for the 6 cups of mini marshmallows. 

How to Store Rice Krispie Treats

Rice Krispie treats will maintain their chewy goodness if they are kept in an airtight container in a cool dry place for up to 4 days. For grab-and-go snacks, cut and wrap them individually to pop into a backpack or briefcase!
