FAQs

Can I use regular peanut butter?
Yes, but just make sure it doesn’t have added sugars or unhealthy oils. Sugar-free peanut butter keeps this mousse keto-friendly.

Can I make it ahead of time?
Absolutely! It’s actually better if you let it chill in the fridge for a few hours (or overnight)—it gives the flavors a chance to meld together.

Can I add chocolate to this mousse?
Heck yes! For a chocolate-peanut butter combo, just add a tablespoon of unsweetened cocoa powder or sugar-free chocolate chips to the mix.
