Trigger warning! If peanut butter is your kryptonite, you may just want to look away for a while. Because these keto peanut butter bars are bound to make you weak in the knees. They are no bake bars, and so easy to make, even your kids could do it on their own.

If you’ve followed me for a while, you know that peanut butter is my jam. I have so many delicious keto peanut butter recipes, and about a zillion ideas in my brain for more. I’m never ever going to stop making delicious sugar free treats with peanut butter. Never ever. Don’t even TRY to convince me otherwise.

Some of my most popular keto peanut butter desserts include: Keto Peanut Butter Brownies, Keto Peanut Butter Dirt Cake, and the brand new but insanely popular Keto Peanut Butter Pie.

My recipe for these no bake peanut butter bars has been around forever, almost from the moment I started blogging. It used to be part of a very old collaborative low carb cookbook, but I decided to share it on the blog back in January of 2016. And today, I decided to update it with a new new video.

So now I can show you just how insanely easy these are to make.

Is peanut butter keto?

This is a question I get from readers frequently. And it stems from a misunderstanding about what the keto diet really is.

The most basic definition is as follows: a keto diet is any diet that keeps you in ketosis. The food itself is not “keto” because anything in tiny quantities will not kick most people out of ketosis. This means that even a small bite of banana or potato could be part of a keto diet, if you really wanted to work it into your macros.

This is not something I really recommend, since tiny amounts of old high carb favorites are not very satisfying. They may also trigger cravings and you could easily find yourself overeating.

So why do some people say peanut butter is not keto? Because there are many specific keto “programs” and keto “coaches” that have approved and not approved food lists. And because peanuts are technically legumes similar to beans, some programs have put them on the naughty list.

There is nothing about the lowly peanut that makes it keto or not keto. It’s actually quite a low carb food choice. So if you are like me, and simply do keto your own way (which is whatever way that keeps you in ketosis), then peanuts and peanut butter can be part of your healthy diet.

I don’t recommend eating it by the spoonful or even eating it every day. But the occasional keto peanut butter treat is usually not a problem for most keto dieters.

How to make easy keto peanut butter bars

Did I mention how easy these no bake bars are to make? Yes? Well let me say it again: they are ridiculously easy. They take only 6 basic ingredients, and come to together in about 15 minutes.

My recipe for keto peanut butter bars takes peanut flour, and I get a number of questions about what that is and whether you can use other keto flours instead. Here’s what I can tell you:

Peanut flour is a good choice for a number of reasons. Peanut flour is basically peanuts that have been roasted and ground to a fine powder, so it helps intensify the peanut butter flavor of the bars.
The powdery consistency is what gives these bars their unique texture. The dough becomes like cookie dough and is soft enough to be pressed into a pan but firm enough that the bars are solid at room temperature.
Peanut butter powder and PBFit are essentially the same thing and work just as well. Just make sure that whatever you choose, it does not contain any added sugars. The original PBFit has sugar, but there is also a sugar-free version made with monk fruit. This will make your bars sweeter so you may want to cut back on the powdered sweetener.
You can use almond flour but it has a higher fat content than peanut flour, so you will need more of it to achieve the same dough-like texture. I actually recommend a combination of almond and coconut flour to get the right consistency: about 2 cups almond flour and 1/4 cup coconut flour.
You will know you have the right consistency, no matter what flour you use, when the dough holds together and really feels like cookie dough. Actually, the consistency is more like play dough. A big edible ball of low carb play dough!

How to store Keto Peanut Butter Bars

The great news is that because these bars have nothing in them that spoils easily, they can be made well in advance.

I recommend storing them in the fridge in a covered container, so that they don’t get overly soft. They do stay firm at room temperature for a few hours, if you don’t live in a hot climate. The chocolate topping could get mighty soft and melty in the summer!

They can last up to 3 weeks, if properly stored and refrigerated. To freeze, I would wrap up the bars tightly in plastic wrap, to avoid freezer burn. They can be frozen for several months.
