Can you substitute quinoa flour for regular flour?

Sprouted Grain Crackers

Organic Sprouted Flour (5 cups)
Organic whole buttermilk or yogurt (2 cups)
Unsalted grass-fed butter, softened or melted (1 cup)
Coconut oil, softened or melted (1/2 cup)
Aluminum-free baking powder (1 Tbsp.)
Sea Salt (2 tsp.)

I wanted to make the crackers have a little more fiber content that is why I thought about a quinoa flour substitution. Please advise. Thank you!

You can substitute quinoa flour for up to about half the regular flour. You cannot, however, use only quinoa flour in baked goods such as those because they'll crumble and fall apart. If you're trying to make something gluten-free, you need to introduce a binder flour that will work with the quinoa flour and hold it all together. For 1 cup regular flour, I'd suggest: 1/2 cup quinoa flour, 1/2 cup sweet rice flour, 2-4 Tbls tapioca starch. If you have a specific recipe in mind, note it here and I can help you make a good guess at the conversions. Good luck!
