Dear Peanut Butter Cookies,

I love you.

There’s just something so special to me about peanut butter cookies. They have always been my very favourite type of cookie, one that I absolutely cannot resist never mind live without. I have magical memories of my Grandma making them for me, knowing that they were my favourite. It used to always amaze me that she knew just how much they meant to me.

Well that love turned into a love/hate relationship when I grew a little older and had to start watching every crumb that entered my body because I will literally gain weight just but smelling food. Butter? Peanut butter? All that flour and sugar? Yup, I could see the scale in my mind climbing as I was indulging in these beauties.

The turning point? I learned a whole new way to eat and started down this low carb path to better health. The best part? I can easily make Low Carb Peanut Butter Cookies fit into my lifestyle! Score!

Ingredients

  • organic peanut butter with no additives
  • powdered monk fruit / erythritol sweetener

Organic Peanut Butter – Not only are generic brands of peanut butter packed with unnecessary ingredients, but non organic peanuts can be loaded with pesticides. I highly recommend you only buy organic peanut butter and peanuts! Want to read a bit more about why you should only buy these organic? Check out this article from BodyUnburdened.

Powdered Monk Fruit / Erythritol Sweetener – My favourite low carb sweetener! I buy the granular sweetener from either SoNourished or Lakanto, and turn it into powdered by blitzing it in a clean coffee grinder for a moment or two!

Expert Tips

Here is a list of some tips and tricks for making these low carb peanut butter cookies that I hope you find helpful!

  • Do you hate mixing organic peanut butter when you first open it? Try using an electric mixer with only one beater attached.. it mixes peanut butter up easily and effectively.
  • Does your peanut butter contain salt? If yes, cut the salt in the recipe down from 1/2 tsp to 1/4 tsp.
  • Cool for at least 10 minutes on the cookie sheet before transferring to a cooling rack or plate to fully cool. These cookies are easily damaged when warm if not careful, but totally solid once cooled!
  • These Low Carb Peanut Butter Cookies will stay fresh for a couple of days if kept in an air tight container at room temperature. Want them to last longer? They will last 4-5 months in the freezer.
  • Try these beauties dipped in unsweetened almond milk!

    Peanut Butter cookies are my daughter’s favorite thing in the whole world. I tried this recipe, instead of our standard traditional one, and they were soooooo good! Thank you so much for sharing!

    I never knew that they use peanuts to “clean up” other bad things in gardens. That doesn’t sound appetizing at all! I already look for the most natural peanut butters I can find, so I’m feeling pretty good. These cookies look fabulous and so simple to make

    I have a serious weakness for peanut butter cookies. The only problem is, I work at a nut free school. More for me, but that means a LOT more for me!!
