FAQ

Can I use regular eggs instead of chia eggs?

Yes, substitute with 2 regular eggs beaten. This will make the bars non-vegan but will work well for binding.

How long do these bars keep?

Store in refrigerator for up to 1 week in airtight container, or freeze for up to 3 months wrapped individually.

Can I make these without oat flour?

Yes, substitute with additional 1/2 cup quick oats or grind your own oat flour from quick oats in a food processor.
