This recipe will teach me once and for all to make sure I read everyone's reviews before starting to cook!! I made these into drop cookies and followed the recipe exactly. They were quite good, but as other reveiwers suggested, the amount of corn flakes does need to be reduced significantly. So this time around, my cookies are a bit dry, but next time I will reduce the corn flakes to 8 cups.

This recipe reaches perfection with a package of chocolate chips poured over the warm bars and then spread with a knife after they soften. Also, for gooier bars I recommend increasing the corn syrup and peanut butter by 1/4 cup.

I grew up on this recipe! They used to serve this to me at my public elementary school cafeteria.

I have made this recipe for a long time by dropping it from a spoon in clusters! In order to add more crunch to it, I use Frosted Flakes instead of plain ole' cornflakes. Yummy.

Wow! Other people actually have heard of this! ;) I have been making this since I was a kid, but we call it "Cornflake Stuff". I had a 'retro' moment this week and have made it 4 times. It's so easy and so good. Your recipe is like mine, only I use the microwave, 3 minutes or until bubbling is perfect. I just spread it out on wax paper so it's big and gooey. Crunchy peanut butter works great if you're a peanut lover.

Great! I use 8 cups instead of 10, less dry!

This recipe is exactly like the ones I used to eat in our middle school cafeteria (bought for a dime apiece). Based on other reviews, I doubled all ingredients except the cornflakes, and they turned out perfectly. I used a large plastic bowl for mixing, and just tossed the flakes with the syrup using 2 wooden spoons. Easy breezy!

I love the taste of these and I do it with different types of cereal all the time. I add a little more peanut butter though because of preference.
