This is a recipe my mommy used to make a lot when my brother and I were still living at home, mostly when we were little. These were perfect to keep us from getting too hungry between meals, all the while being both healthy and just sweet enough to keep us from craving junk food. My brother being a diabetic, anything that wasn't too good for us was forbidden except ice cream (which counts as dairy in a diabetic's diet) and the odd bag of chips (which they can eat in very small portions). Best of all, they're very easy and quick to make!
You will need a rolling pin for this recipe. My mom uses peanut butter, but of course you can use another kind. I would go so far as to say that a natural nut butter may yield the best results. Mom also uses corn syrup, but because it is not the best sweetener available (which we didn't know back then), I recommend melting panela/jaggery in water to make a caramel-like consistency, or using agave or maple syrup. If using maple, only use the dark one as the other two don't work - they're too liquid.
One box of cereal, preferable a corn or bran flake or rice crispies, but nothing fancy - no dried fruits or nuts, just the actual cereal
Half a jar of peanut (or any other nut) butter, preferably natural (or more, if you want)
A few tablespoons of either: corn syrup, agave, maple, caramel-like panela/jaggery
**Before starting, make sure you have enough space to put one or two large cookie sheets in your fridge to harden the energy bombs.
1- On a wooden cutting board, spread out an amount of cereal. Pass the rolling pin over it until it is broken down into small pieces. Put the crushed cereal in a mixing bowl and repeat until you have finished crushing the entire box. Spoon peanut or nut butter on top of cereal and mix with a large wooden spoon. When the cereal is completely covered with the butter, add your sweetener and mix thoroughly.
2- Take out a cookie sheet. With your hands, make small to medium-sized balls with the mix. You may need two cookie sheets depending on the size of ball you want. I recommend the size of a ping-pong ball for small children as - like I said - these are ENERGY balls! For older children, you can go up to the size of an egg.
3- Put in fridge overnight so they harden well. Store in a large tupperware container in the fridge.
