Peanut Butter – You’ll need some creamy peanut butter for these keto peanut butter cookies. We used the Jif No Sugar Added Peanut Butter this time around – we just recently started seeing it in our grocery store and we love it!

Brown Sugar Sub – A good brown sugar substitute that we use in pretty much all our recipes is Lakanto Brown Monkfruit Sweetener. It’s the perfect low carb replacement for brown sugar!

Almond Flour Almond flour works great as a replacement for flour in these keto peanut butter cookies, it holds together well with a great texture!

Shop Keto Ingredients

We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.

Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.

They have monthly or yearly plans. Check it out here.

How To Make Keto Peanut Butter Cookies:

  • Cookie Dough – First up you’ll prepare the peanut butter cookie dough. This is a pretty simple recipe with only a few ingredients. Add the creamy peanut butter to a mixing bowl with the brown sugar substitute, egg, and vanilla extract and beat together with an electric mixer until it is all well combined. Finally go ahead and add in the almond flour and baking soda and mix it well to form the dough.
  • Scoop – The best way to make sure you get the cookies sized properly so they bake evenly is to use a cookie scoop. I was able to get 20 balls of the keto peanut butter cookie dough using a medium sized cookie scoop. Scoop the balls of dough and sort them out onto a parchment lined baking sheet. almond flour cookie dough in cookie scoop.
  • Flatten – Use your hands to roll the balls into a nice circle and then press a fork into the tops in a crisscross pattern.  Peanut butter cookies are thick and this will help flatten them out so they bake a little more evenly. cookie dough on baking sheet.
  • Bake – When you’ve finished preparing the balls of cookie dough on the baking sheet you can start baking. These do not take long, only about 8 to 9 minutes. They may look a bit underdone, but they’ll set up as they cool on the hot baking sheet.  Serve them up with a cold glass of almond milk!
Helpful Tip!

Use a medium cookie scoop to quickly and easily scoop out equal sized portions of dough. Roll the dough quickly between your hands to compact and smooth it before using a fork to make the crisscross pattern.

Can I store peanut butter cookies?

Sure! These will keep well like most other cookies. Store them in an airtight container at room temperature for up to a week.

Can I freeze the cookies/dough?

Absolutely! To free before baking, scoop and shape the dough, place on a baking sheet, and freeze for 1 hour before transferring to a freezer safe bag for up to 3 months. Bake straight from the freezer for 10-11 minutes. To freeze already baked cookies, cool completely and freeze in a freezer bag for up to 3 months. Thaw on the countertop.

Why make a crisscross pattern?

It flattens out the cookies so that they will bake more evenly. The dough is pretty thick so if you don’t flatten them out the centers may not be done.

      Hi Steve! The almond flour and brown sugar replacement are both in the recipe card, but are linked out to the store where I bought them. My guess is that you have an ad blocker on your browser that is hiding the information.
