My Tips

Recipe Tips and Substitutions

For a gluten-free option, make sure you buy gluten-free oats.
Instead of peanut butter, use cashew or almond butter. You can even try sunflower butter if you have a nut allergy.
Use vanilla protein powder instead of chocolate powder for fewer chocolate flavors.
In place of the peanuts, roasted almonds or cashews can be used.
For extra nutty flavors, sprinkle some unsweetened shredded coconut in the oat mixture and on top before baking.
Dried fruit, such as cranberries, raisins, dates, etc., will work great for this recipe!
