FREQUENTLY ASKED QUESTIONS:

Can I use different cereal?

As long as you’d think that the flavor of the cereal would go well with this mixture, then you can do it. It can be done with Rice Krispies or even Crispix cereal.

What chocolate is best to use?

I think semi-sweet chocolate is the way to go for the drizzle. It gives it a nice contrast of flavor without being too sweet.

Do I have to drizzle with chocolate?

No, this is not a necessary step and you can leave it off. You could maybe even add some sprinkles on top before the cookies set up.

Can I use crunchy peanut butter?

If you want some added texture you can use crunchy peanut butter for this recipe. I would stay away from natural peanut butter as it is too runny and won’t hold these together that well. I have not tested this with other nut butters so I can’t say how well they would hold up.

How long do these need to set?

The cookies themselves will set up in about 30 minutes. The chocolate added takes about another 15 minutes.

Can cornflake cookies be frozen?

Yes, cornflake cookies can be frozen. To do that, place cookies in a freezer-safe container separated by parchment paper and they will keep for up to 1-2 months. Let defrost on the countertop. Also, these can be stored in an airtight container where they will keep at room temperature or up to 3 days and up to 10 days in the refrigerator.
