FAQ

Can I use natural peanut butter for these recipes?

Yes, but make sure it's well-stirred and not too oily. Natural peanut butter can sometimes make the cookies softer, so you may need to chill them longer.

How should I store no-bake keto peanut butter cookies?

Store them in an airtight container in the refrigerator for up to a week. They can also be frozen for up to three months.

Can I substitute almond flour with coconut flour?

Coconut flour is more absorbent, so use about 1/4 cup for every 1 cup of almond flour. You may also need to add an extra egg or a bit more liquid.

Are these cookies suitable for a dairy-free diet?

Most recipes are dairy-free if you use dairy-free chocolate and butter substitutes. Check labels to ensure all ingredients are dairy-free.

Why are my no-bake cookies too soft?

They may need more chilling time, or the mixture might be too wet. Try adding a bit more almond flour or coconut flour to absorb excess moisture.
