For FHE I was in charge of treats and was frantically looking for something quick and that my 15 month old would enjoy. I found marshmallows but no rice krispies so I used cheerios and it was a tasty and healthier choice.
1/4 c. butter
1 (10 oz) package marshmallows
8 c. cheerios
Melt the butter in a large pot. Add package of marshmallows, stirring occasionally until marshmallow is melted. Remove from heat and add cheerios. Stir until cheerios are evenly coated with marshmallow. Press into a greased 9x13 inch dish.
