Every once in a while, you need to go a little nuts. With ONE Peanut Butter Pie, you can do it a whole lot more often. That’s because on top of being packed with the flavor of peanut butter in a scrumptious treat, it’s also packed with 20 grams of protein. The only thing missing? All that sugar: it’s only got 1 gram. So have another slice, whether you’re headed to the gym or headed off on your commute. You’ve saved room for dessert.


When it comes to snacking, every single one of us is entitled to the perfect match. And at ONE we believe that great taste and good health are not mutually exclusive. But those other chalky protein bars? A definite swipe left (and let’s be real – life’s too short for boring anything.) So we’ve taken our passion for flavor and shaped the perfect snack. One that’s loaded with protein. One that’s low in sugar. One with totally indulgent flavors that seem too good to be true. So stop playing the field, and make it official – with our anytime Guilt Free Indulgence.

Congratulations, You’ve Found the ONE.

    Absolute best protein bar on the market. I have tried probably every low carb bar out there. I was completely hooked on quest bars until they changed the kind of fiber they used in them. This bar however is even better than the original question bars. I have a hard time not eating these all day. They actually taste like birthday cake, great texture taste and macros. You really can’t go wrong with these unless you eat a whole box. Lol. Trust me I’ve never had a protein bar that tastes this good. High protein low sugar. Great!

    I have tired all of the One Protein bars and absolutely love most of them and this one is in my top 3. Peanut butter pie and cookie dough are my other favorites.

    If you were to buy these bars individually at the grocery store you would be paying close to a dollar more each bar. This is an amazing deal! Also they are the best flavor and texture protein bars I’ve ever had! HANDS DOWN! They aren’t chalky or dry at all. The flavor is AMAZING!

    I love this product! It’s not dry like other keto friendly bars! A++ and five stars for the packaging including an ice pack to keep them from melting!
