Keto Peanut Butter Cookies!

I’m surprised it took this long to post low carb peanut butter cookies, I guess because they’re gone so quickly once they’ve baked!

Peanut butter cookies hold a special place in my heart because they’re the first dessert recipe I ever made at the young age of 10. And it figures, there are only three ingredients needed for them! Traditionally, they are sugar, peanut butter and an egg. Simple enough for kids and delicious enough to enjoy at any age.

Luckily, it is easy to create a low carb version of peanut butter cookies and still keep the recipe extremely simple. To make these low carb and keto-friendly, the only thing needed is to swap out sugar for erythritol! Even my 10-year-old baking self could still make them!

The brand of erythritol we use is Swerve or Sukrin. They’re found in a lot of grocery stores near us and fit our budget when we need to stock up on low carb sweeteners! Swerves erythritol is ground much finer than most erythritols which makes baking a lot simpler because erythritol is a bit more difficult to dissolve in water than regular table sugar. The finer grind of the sweetener makes it blend into the keto peanut butter cookie batter well. You can also get a confectioners’ version of erythritol which helps in baking even more- especially for frosting!

After you make the cookie dough for these keto peanut butter cookies, you can scoop the dough into balls and then roll them in some extra granulated erythritol. This will add a little sweetness and it is also a classic touch that is added to many peanut butter cookies. That sparkly sweetener on the outside is hard to resist!

The original recipe that’s been posted countless times all over the internet calls for a cup of sugar for about 12-15 cookies. Based on my experience, I decided to add in half a cup of erythritol. Being keto-adapted, my tolerance for sweets has decreased drastically. And experimenting with keto desserts has taught me to cut the sweetness! Even though erythritol is only about 70% as sweet as sugar, I still used a small amount and the low carb peanut butter cookies still turned out sweet and perfect! You won’t even notice that the sugar content has been reduced!

I suggest starting off with this small amount of sweetener and doing a taste-test. I figured since peanut butter is a treat to me to begin with, adding a whole ton of sweetener wouldn’t really be necessary. Let that natural sweetness of the peanut butter shine through!
