If you have a craving for a peanut butter cookie and don’t want to grab all those other ingredients, try these easy peanut butter cookies! I promise you they are just as good, if not better, than any other recipe!

I have been on a “keto/low carb diet” for the last 5 years. When I crave something sweet and want something easy, this is my go to. The kids often grab them as they are cooling and they don’t even know the difference!

These cookies are super easy to make, are chewy and perfect for when a late night craving hit.

how can i make keto peanut butter cookies?

The answer is to use a sweetener alternative. I personally don’t enjoy the “cold sensation” that erythritol leaves. I’ve searched high and low for a great sugar free altnerative and I prefer Sukrin.

  • Smooth Peanut Butter – you can use crunchy if you choose, but, I like the texture of the smooth. I try to use Jif at all possible and not the natural kind of peanut butter here as it is entirely way too thick.
  • Sweetener – either the sugar free substitute as mentioned above or granulated sugar works too if you don’t care about keto, low carb or a sugar free diet.
  • Egg – all you need is egg.

You can also use a teaspoon of vanilla should you choose. I’ll throw it in sometimes if I’m not in a hurry!

Using a fork, make your cross pattern. TIP: If the fork wants to stick to the dough, spray the fork with non-stick cooking spray!

Bake in a pre-heated 325° oven for 8-10 minutes, until the center has just set. Baking any longer will result in a crispy cookie and we don’t do things like that here!

why are my 3 ingredient peanut butter cookies falling apart?

One reason your cookies may be falling apart, is you need to use real peanut butter.

Another reason that the peanut butter cookie could be falling apart is it needs to cool. Once you remove the cookies from the oven, allow to sit for 2-3 minutes before you move them to a cooling rack. The cookie is still baking and because we are removing the cookies from the oven as soon as the center sets, it needs those few minutes to firm up.

why do you put fork marks on peanut butter cookies?

This is a great question. I had a friend argue with me about this years ago. Peanut butter is a super thick ingredient. Adding the criss-cross pattern or “fork marks” allows the cookie to bake evenly.

what type of peanut butter is best for cookies?

In my opinion, I prefer the creamy Jif peanut butter. It’s easy to work with and great a great smooth consistency. The problem with using a natural style peanut butter is the oil on the top. It needs to be mixed very well so the consistency is the same throughout. It’s hard to do.

I’ve used both Jif and Skippy for this cookie recipe and those both work perfectly!

how to store and freeze peanut butter cookies

Store: Baked goods can be stored in an air tight container for about 5 days, if you can get them to last that long!

Refrigerate: Refrigerate cookie dough with plastic wrap for up to 3 days.

Freeze: To freeze cookie dough, line a baking sheet with parchment paper. Press with a fork making your criss-cross marks and then freeze until they have hardened. Store in an air tight container or freezer bag for up to 3 months. When it comes to baking cookie dough that has been frozen, allow the dough to come to room temperature before baking for best results.
