FAQs

Can I use quick oats instead of rolled oats?

Yes, but the texture will be softer and less chewy. Rolled oats offer a heartier bite.

Can I make these bars nut-free?

Yes, substitute almond flour with oat flour and use a nut-free milk like rice or soy milk.

Why are my bars too soft?

If they’re underbaked, add 5 more minutes of baking time. Also, make sure not to add too much liquid.

Can I replace bananas with applesauce?

Yes! Use an equal amount of unsweetened applesauce for a milder flavor.

How do I make the bars extra crispy?

Bake for an additional 5-10 minutes until the edges are golden brown and crisp.

Are these bars gluten-free?

Yes, as long as you use certified gluten-free oats.

Can I add protein powder?

Yes! Replace ¼ cup of oats with your favorite protein powder for an extra protein boost.

How long do they stay fresh?

They’re best within 5 days if stored at room temperature but last up to a week if refrigerated.

Can I use dairy milk instead of almond milk?

Yes, any milk works well in this recipe.

What’s the best way to cut oatmeal bars cleanly?

Let them cool completely and use a sharp knife, wiping between cuts for clean edges.
