Peanut Butter Cornflake Cookies Recipe

This easy no bake cookie recipe is the perfect starter recipe for small children. First off, there’s only 4 ingredients, and they get experience using liquid and dry measuring cups.

This brings up a good point. While baking, be sure to use a liquid measuring device for all ingredients such as corn syrup. Use dry measuring cups for dry ingredients like cornflakes.Using the incorrect measuring devices can impact the results of your desserts in a negative way. Check out our “Kitchen Stuff You Need” list in our Amazon storefront to see items – like measuring cups – that we have in our kitchen!

Peanut Butter ranks at the top of my favorite list (along side chocolate), and these easy cornflake cookies are packed in peanut butter flavor. Growing up, the mom of my sister’s BFF made these for us. Obviously they are delicious, because I’m still making them after all these years. I even came up with a similar version with marshmallows because I love these cookies so much!

Another great thing about these peanut butter no bake cookie treats is that you don’t need the oven.All the work is done on the stove-top which keeps the kitchen from getting hot during those summer months.My family lives in my grandparent’s old farm house right smack on the farm, and we get by with a couple window air conditioners. Using the oven really heats up the house. On those super hot summer days, I love making no bake recipes for dessert.
