Can I make these in the microwave?

Yes—melt the butter and marshmallows in a large microwave-safe bowl in 30-second intervals, stirring until smooth.

Can I use other cereals?

Yes, try Cocoa Krispies, Cheerios, or Cornflakes for a fun variation.

Can I double the recipe?

How do I cut clean squares?

Grease your knife or spray it lightly with non-stick spray before slicing.

Can I make them dairy-free?

Are these gluten-free?

Rice Krispies contain malt flavoring (barley), so choose a certified gluten-free crisp rice cereal if needed.

Can I add protein powder?
