Common Questions
Can I use coconut flour instead?
No, coconut flour absorbs much more moisture than almond flour. The ratios would be very different for this recipe. Stick with almond flour for the best results.
How do I know when they are done?
Look for the edges to be just barely golden brown. The centers will still look a bit soft. They firm up perfectly as they cool on the tray.
Will my kids eat these sugar-free cookies?
Yes, these cookies are very kid-approved and sweet. The buttery texture hides the fact that they are keto. They are a great healthy snack for lunchboxes.
