You are just a few minutes and a handful of ingredients away from a delicious sweet treat. The peanut butter layer is sweet and chewy with  the crunch of corn flakes throughout.

Of course a layer of chocolate on top brings it all together. These no bake treats will become your favorite quick treat!

Ingredients: corn flakes, peanut butter, sugar, corn syrup and chocolate chips ready to be made into scotcharoo bars.

If you have a saucepan, a spoon and a few pantry staples, you are well on your way to a fabulous treat. Just melt together some peanut butter goodness and stir in plenty of cornflakes.

Then press that delicious mixture into a greased pan. Go ahead and give it a good press, that is what is going to hold it all together as it sets.

Then melt together some chocolate and peanut butter and spread it over the top.  The peanut butter not only drives home the flavor combo, but keeps the set chocolate softer.

So as you take a bite, you get that creamy chocolate that gives way to the chewy crunch of the peanut butter and corn flake layer.  They are so quick and easy to make, you will want to do it all of the time.

They would be great after school snacks or perfect for drop in guests you weren’t expecting.  They are always just a few minutes away and a happy surprise to those they are served to.

Can I use something other than peanut butter?

Yes, other nut butters would work great in this recipe. Almond butter would be tasty or sunflower butter if that’s your preference.

Tips and tricks:

Go ahead and crunch up the corn flakes a bit while you are stirring, you don’t have to be gentle and keep them whole.

Give the peanut butter mixture a good smash down when you transfer it to the pan.  That is what is going to hold them together when it’s time to cut and serve them.

Be careful not to overcook the chocolate chips when you are melting them.  Give them a good stir between each trip to the microwave and stop as soon as it stirs smooth.

Could you substitute honey for the corn syrup?

I dont have chocolate chips. Recommendations for chocolate?


Saturday 19th of November 2022

If you have chocolate bars, that would work. Otherwise make a batch of fudge icing instead.

Does it matter what peanut butter I use? Can I use all natural?


Sunday 12th of December 2021

I haven't tried it, but I think it should work ok in these. Let me know how it goes!

Not sure what i did, corn syrup may have been old but it was harder than rick when it set. Our goat likes them though. Will try again with new syrup.


Saturday 20th of November 2021

If it gets over caramelized it can set really hard too. I'd either cook it a little less time or a little bit lower temperature next time.

I’m thinking of making these without the chocolate , but I want to add some marshmallows and candy corn., Do you think they will both just dissolve in the heat/warmth of the mixture?


Saturday 6th of November 2021

I would think if you add them at the end with the cereal they should be fine. That sounds really delicious!
