FAQs

What’s the difference between a blondie and a brownie?

Blondies are like brownies but without cocoa, relying on brown sugar and vanilla for flavor.

How do I know when they’re done baking?

Insert a toothpick into the center—if it comes out with a few moist crumbs, they’re ready.

Yes, use a 1:1 gluten-free flour substitute.

What can I substitute for butter?

You can use coconut oil, but it may slightly change the flavor and texture.
