Ingredients, Tips, & Substitutions


This is where the natural sweetness comes from in this recipe. Raisins are high in fiber with tons of antioxidants, and even have a bit of iron and calcium.

If you don’t have raisins, you can use almost any other dried fruit you have, provided it’s sticky on the inside – dates, apricots, prunes, cranberries, etc. would all be great! Dried pineapple, for example, would probably not work as well.

Peanut Butter

I love peanut butter for a variety of reasons. In this recipe it not only is amazingly delicious, but acts like a glue (along with the raisins), to hold the bars together. Peanut butter is a good source of healthy fats and protein, so opt for regular peanut butter and never low fat (when the fat is removed it’s often replaced with sugar for only a minimal calorie reduction!).

If you like another nut or seed butter, use that instead. Almond butter, cashew butter, soynut butter, sunflower butter… any and all will be phenomenal.


Who doesn’t love Cheerios? Delicious, whole grain, mildly sweet, yet low in overall sugar, they are the perfect cereal to use. Any variety you have will work (I used Multigrain Cheerios because that’s what I had)! Just know that if you use a variety other than regular, you may end up with more added sugar.

Other cereals will work too if you don’t have Cheerios! Rice Krispies, Chex, and a wide variety of other cereals are good choices. Try to keep it on the lower end of added sugar if you can, but use what you have!

Mixed Nuts

Nuts are a fantastic choice for heart health! So many healthy fats, fiber, protein, and vitamins and minerals! I love mixed nuts because then I don’t have to choose just one! Look for unsalted if you can find them – I get giant tubs at Costco! For this recipe, it doesn’t matter if they’re roasted or not. You choose!

If you don’t have mixed nuts, use any nut you have. Walnuts, cashews, peanuts… they all work. If you are allergic to nuts, or just don’t have any, seeds are good options, too. Sunflower seeds would be great. I’d just caution against using very small seeds like Chia or Flax. If you use those, you’ll likely have to cut the amount you use. I’ve not tried it, though, so I can’t recommend an amount. If you try it, let me know what proportions you use and how it works!

How to make these cereal bars

You will love how uncomplicated these are!

First, you’ll want to soak your raisins in some warm water for at least 20 minutes. They will plump up and this will make them easier to blend into the peanut butter. When you drain them, save the liquid in case you need it during blending. Dump the drained raisins in your blender.

Now the peanut butter. This will work best if you warm your peanut butter in the microwave for a bit so it’s more liquidy. Into the blender it goes with the raisins. Now blend on high until you get a thick paste. If you need to add some liquid, add the raisin water, a little at a time. You still want it to be really thick!

In a separate bowl, combine the Cheerios and nuts. Pour the raisin-peanut butter paste into the bowl, and mix everything really well.

Turn the mixture out into an 8×8 in pan, or similar size, lined with waxed paper. Press the whole mixture down firmly, using the back of a spoon or your hand, if necessary.

Pop the pan in the freezer for an hour before trying to slice into bars. This makes 14 bars. Once you cut them, you can store them in the refrigerator up to a few days.
