Frequent Questions
You can use any size marshmallows you like, whether mini or large marshmallows. Some people like to use marshmallow creme but your end result will have a different, softer texture. If you like that, go ahead and use them.
I do not recommend using the microwave to melt your marshmallow mixture as the marshmallows might expand and make a big mess.
Variations
- Chocolate: Indulge your sweet tooth by spreading the top with Chocolate Ganache. Allow the ganache to set, refrigerating for 30 minutes if the weather is too warm, before cutting. Another idea is once you stir the cereal into the marshmallow mixture, cool for 5 minutes then fold in your favorite chocolate chips. Don’t stir too much (the chocolate will start melting), and press into the pan. Top with more chocolate chips.
- Marshmallows: Reserve 1 cup of mini marshmallows and fold into the cereal mixture about 5 minutes after mixing, then press into the pan.
- Nuts: Give your cereal bars some protein by mixing in 1 cup chopped peanuts, cashews, or slivered almonds with the cereal.
- Dried Fruit: Fold chopped dried fruit into your cereal bars like dried strawberries, blueberries, bananas, or apples.
- Cheerios Flavors: Swap out the classic Cheerios for other flavors like Honey Nut Cheerios, Frosted Cheerios, or Chocolate Cheerios.
- Cereal: Don’t stop at Cheerios! Use other classic cereals like Raisin Bran, Rice Chex, Grape Nuts, or Special K Flakes instead.
- Peanut Butter and Honey: Instead of the butter and marshmallows, use honey and creamy peanut butter. Melt ¾ cup creamy peanut butter with ½ cup honey. Toss 3 cups cheerios in the warm honey mixture and press into a pan. Cut into squares when cooled.
