What can you add?

I love using what I already have in my pantry and sometimes that means trying new things. Here are some of our favorite add-ins:

Change up the cornflakes:

The possibilities are endless! You can take this recipe and make corn flakes squares a ton of different ways. They will be great using frosted flakes instead of plain corn flakes. Chocolate Frosted Flakes taste amazing too! 

The no bake bars are always a hit all around. Do you have a chocolate lover in your house? You could make chocolate corn flakes.

If it is too much chocolate for you, try mixing in a few plain corn flakes with the chocolate frosted flakes. This will cut down on sugar and help with the sweetness.

How to make Cornflake Bars Marshmallows:

  • Then mix in the cornflakes until they are coated. Using a butter spatula helps make sure the cornflakes are mixed well.

  • Press firmly into the into the prepared pan, but not to push to firmly as you don’t want to crush the cornflakes. The cornflake bars marshmallow mixture will be sticky. I use the butter spatula to make sure it is pressed into the pan.
  • Make sure you let cool completely. Next, lift out and cut into squares. When using parchment paper it makes it easy to lift out of pan and cut into squares.
  • This recipe makes 16 small squares or about 9 large squares. You can even use a disposable pan to make clean up a breeze. I’m all for making things easy around here.

These are perfect to make for your gift giving this holiday season. You family and friends will love them on their cookie trays. You can even take them for a cookie exchange party.

Can these be made on the stove top?

Yes, these can be made on the stovetop instead of the microwave. Melt the marshmallows and butter in a large sauce pan over low heat.

Stir until melted and well combined. Remove from heat and then mix in the cinnamon and corn flakes. Then pressure the mixture into the pan.

How to store Cinnamon Cornflake Squares:

These cornflake bars are easy to make and easy to store. Store in an airtight container at room temperature. They don’t last long in my house but are perfect to keep for an easy snack. Do not store in the refrigerator or they will become dried out and loose their gooey texture.

    I don’t recommend freezing these. I find that the marshmallows great crisp and crunchy after this has been frozen and I prefer them to be gooey!
