Frequently Asked Questions (FAQ)

Can I use granulated sweetener?

Are these blondies gluten-free?

Yes! This recipe uses only almond and coconut flour—both naturally gluten-free.

How do I store these blondies?

Store in an airtight container in the fridge for up to 5 days. Freeze for longer storage.

Can I make them nut-free?

Try sunflower seed flour or lupin flour in place of almond flour for a nut-free option.

What can I use instead of coconut flour?

Coconut flour is highly absorbent and cannot be substituted 1:1. If needed, try 1/4 cup psyllium husk powder or oat fiber , adjusting liquid as needed.
