Amanda, a dear friend of mine, grew up making these cookies with her grandma and she still cherishes making them today. They were always her cookie of choice whenever she had to take anything for school functions or parties. I hope that you enjoy them as much as we have over the years.

What Add-Ins Are Suggested For These Cookies?

If you want to try and mix it up, try adding these items of a different flavor:

  • Chocolate Chips
  • Butterscotch Chips
  • Coconut
  • Raisins

If you choose to add Coconut, I suggest following Kim’s recommendation. Lower the amount of Rice Krispie cereal to one cup and add one cup of coconut.

Don’t forget the glass of milk with these cookies. They go perfectly together.

Can I Use Quick Oats For Baking Cookies

Most of the time, regular rolled oats and quick oats are interchangeable unless a recipe specifically states which ones to use. If the recipe states rolled oats, do not substitute with quick oats.

I suggest using regular rolled oats for these oatmeal rice krispie cookies.

The main difference between the rolled and quick is that the quick oats have been broken down into smaller pieces and they tend to have more oatmeal dust. If you choose to use quick oats, just know that it will not yield the same texture as an oatmeal cookie made with rolled oats.

There is another type of oatmeal, steel-cut. Do not use this type of oatmeal for baking. It requires a longer cook time and is much better for a breakfast meal.

    I made these tonight as I wanted to use up some Rice Krispies. I cooked them in my convection oven at 325 degree for 12 minutes. The first batch I cooked them for 10 minutes (same temperature), they weren’t baked long enough. The cookies taste good. Not a ton of flavour but still good. I’d make them again.

    I made the recipe but because I like coconut in these cookies I cut out one cup of Rice Krispies and substituted it with one cup of coconut and added I cup of mini chocolate chips. I also like a crunchier cookie so I baked them 12-13 min. Such s tasty cookie. My mother loves them! Thanks!

  5. Made these with my boys and they’re great. We added 1 cup of M&Ms and took a bit more baking time. yummm!
