This Keto Peanut Butter Cookie Recipe Is Sweet, Simple, and Totally Guilt-Free!

When you’re following a keto lifestyle, finding a sweet treat that’s both satisfying and low-carb can be a challenge. But these keto peanut butter cookies?

They hit all the right notes—rich, nutty, and incredibly easy to make. Plus, they’re sugar-free, so you can indulge without guilt.

These cookies are my go-to when I need a little something sweet but don’t want to break my carb count for the day.

I first made these on a lazy weekend when I wanted a keto-friendly dessert that wouldn’t derail my diet. After the first bite, I was hooked.

The soft, melt-in-your-mouth texture combined with the bold peanut butter flavor makes them perfect for a midday snack or a light dessert after dinner.

What makes this recipe even better is how simple it is. Just a few ingredients—almond flour, peanut butter, and a sugar substitute—combine to create the perfect cookie.

If you’re looking for an extra treat, pair these with a cold glass of almond milk or a refreshing iced coffee to complete your experience.
