What can be made from corn flakes?

What can I do with hard marshmallows?

To make hard marshmallows soft again, try the same old trick that works with brown sugar. Add a piece of bread to the bag of marshmallows, seal the bag and let it sit for a couple days. The moisture in the bread should migrate to the hard marshmallows, helping to soften them in texture.

Once they are softened, use them to make your favorite no-bake sweets, including:

Church Windows (with colored marshmallows)
White Chocolate Peanut Clusters
Salted Nut Squares
Indoor S’Mores Bars
Cornflake Candy with Marshmallows (see recipe below)

What are drop cookies?

The term drop cookies refers to a type of cookies that are scooped and then dropped onto a baking sheet or parchment paper. Some types of drop cookies are baked (such as chocolate chip cookies) while others are no bake cookies (such as peanut butter cornflake cookies).

Notes About Cornflake Candy with Marshmallows:

Use creamy peanut butter instead of crunchy, if desired.
To help the corn syrup pour easily from the measuring cup, spray it first with nonstick cooking spray.
Melted sugar is extremely hot; do not touch the mixture until cooled.
Move quickly when dropping the spoonfuls of cookies onto the parchment paper. They will harden quickly.
Try adding some more fun add-ins such as coconut, rice krispies, dried fruit, etc.
