Butter Variation
You can substitute cashew, almond, or sunflower seed butter for the nuts if you want a nut-free version or simply want to add a little taste difference.
Honey/maple syrup
You can also use honey or maple syrup to organically sweeten your peanut butter crunch.
Experience with chocolate
You may make your peanut butter crunch extra chocolatey by adding milk or dark chocolate chips if you’d like.
Nuts or Seeds
Add chopped pumpkin seeds, walnuts, or almonds for some crunch.
Dried Fruit

Ground Coconut
Browned, crushed coconut can be added for an appealing tropical taste.
Peanut butter without sugar
For a less-sweet peanut butter crunch, you can use unsweetened peanut butter or manage the quantities of sweet and unsweet peanut butter you are using.
Sugar-Free Cereal
Reduce your intake of processed sugars by switching to whole-grain or unsweetened cereal.
Recipe Tips
Here are some recipe tips to make the perfect peanut butter crunch:
- Just until the sugar melts, heat the syrup and sugar together. If the mixture is overcooked, it may cool too hard.
- To guarantee seamless inclusion, reheat the peanut butter a little or stir it over low heat if it’s stiff.
- Carefully fold the cereal into the syrup mixture, being careful not to smash the flakes.
- Form the clusters as soon as the mixture is finished because it will solidify as it cools.
- To prevent sticking, allow the clusters to cool and solidify completely before storing.
- Keep in a tightly sealed container. For a longer shelf life, refrigerate or store at room temperature for up to a week. Use parchment paper to keep the layers apart so they don’t stick.
- For a finishing touch, drizzle the clusters with white or melted chocolate.
- While the mixture is still warm, add crushed peanuts, colorful sprinkles, or a pinch of sea salt.
