FAQ
Can I use coconut flour instead?
No, coconut flour absorbs more liquid and would require recipe adjustments. Stick with almond flour for best results.
How do I know when the bars are done?
The filling should be set with minimal jiggle in the center. A toothpick inserted near the edge should come out clean.
Can I freeze these bars?
Yes! Wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
