Keto Crunchy Peanut Butter Cookies

Peanut butter cookies are one of my favorite childhood treats. My grandmother used to make them for me. Just the smell of them in the house made my mouth water.

When Rebecca found out how much I love them, she started working on a Keto recipe that would replicate the crunchy, peanut buttery, sweet goodness that I remember.

All I have to say is…. She flippin’ nailed it!

Because my wife is just that badass.

She made a big batch of them for me for Valentine’s Day with a little note that said, “I’m nuts for you.”

That batch of  cookies didn’t make it long enough for me to take a picture.

Since those cookies didn’t make it, she made another batch of her Keto Crunchy Peanut Butter Cookies just for this post. I have to admit, though…. that batch nearly didn’t make it in front of the camera either.

Recipes Notes

Usually, at this point in our recipe posts, I’ll give you some pointers for the recipe, but this one is pretty straight forward. There are only two quick notes:

Confectioners Monkfruit:

Monkfruit is a wonderful, Keto-approved sweetener. Since we discovered it, we’ve started using it in everything that needs sweetness.

Monkfruit sweetener stands up well to the heat of baking, it tastes great and doesn’t have a bad aftertaste. It has no carbs, and actually contains a substance that is reported to help stabilize blood glucose levels.

Amazon is the most reasonably priced and convenient place we've found to purchase it.

The Flour

Or, I should say, the lack of flour. This note is actually an edit because we’ve gotten a couple questions from readers who wonder if we left out a flour substitute from the recipe we posted below.

The short answers is, “Nope. There is no flour of any kind in this recipe.”

Some ‘nut butter’ cookies out there, even on Keto, require almond or coconut flour, but this one doesn’t.

This recipe is based on an old recipe for peanut butter cookies that my grandmother used to make for me (probably why this is my favorite kind of cookie!). Her recipe didn’t call for flour either.

It’s surprising how “crumbly” these get without it; both the regular and the Keto version.

Peanut Butter

Yes, we use peanut butter in these. A lot of strict Keto people won’t even touch a peanut because it’s not technically a nut; it’s a legume.

We don’t eat this all the time and we account for the extra carbs in our daily macros. So, don’t judge us!

Besides, peanuts barely have more net carbs than almonds. The key here is moderation. Don’t do what I did and eat a dozen of these in one sitting.

Or…. maybe just don’t make them very often, becuase you WILL want more than one or two.

You can use other nut butters like Almond or Pecan butter, but the the cookies will taste more like those nuts; each one having it’s own personality.

We use natural peanut butter with no sugar or other fillers added. There are several brands out there that offer ‘all natural’ peanut butter. We like Smucker’s Natural Peanut Butter – Chunky.

Whatever you use, just make sure to read those labels!

This is not an affiliate link or anything. We just really like this stuff and thought this was a good picture. The affiliate link is below! 😉

All Natural Peanut Butter

A lot of people on Keto stay away from peanuts because they do contain carbs.

Sometimes almonds and pecans just won't get the job done. So when nothing else will do, it's best to have them in moderation.

It's also a good idea to choose a peanut butter with no sugar added. Smucker's is the best brand we've found with the fewest ingredients and no sugar.
