Recipe FAQs

Is this recipe allergy friendly?

As written, this is dairy-free and gluten-free. Just make sure you are using ingredients that fit your diet, such as certified gluten-free oats and dairy-free chocolate chips. Peanut allergy? Try almond butter or cashew butter or even sunflower seed butter. Egg allergy? I haven’t tested it, but a flax egg should work nicely.

How can I customize these bars?

Try using nuts for part of the chocolate chips. Mix different varieties of chocolate, such as white and dark. Try dried fruit as well! You can also use applesauce in place of the mashed bananas.
