3 Ingredient Sugar Free Peanut Butter Cookies

Every batch of peanut butter cookies I make disappears almost as fast as you can say “cookie jar.” I can’t seem to resist “just one more” of those perfect treats.

Unfortunately, my blood sugar doesn’t always love sugary cookies as much as my taste buds do. Sure, I could just stop eating cookies to avoid the afternoon sugar crash.

But what kind of life is a life without COOKIES?

No life at all.

So, I dusted off my cookie crumb covered fingers and got to work. By swapping the sugar in the original 3 ingredient recipe for sugar substitute, I was able to get the same amazingly tasty results!

No complicated ingredients or methods. Just delicious, nutty and sweet peanut butter cookies–that won’t wreak havoc on your blood sugar.

3 ingredients for peanut butter cookies.

Ingredients for Sugar Free Peanut Butter Cookies

  • peanut butter
  • egg
  • granulated sugar substitute (see below for my favorites)

THAT’S IT! I love not having to set out a zillion ingredients to make a batch of cookies. Always keep these ingredients stocked and you’re just minutes away from homemade cookies.

Steps for making Peanut Butter Cookies without sugar

Making these cookies is easy as can be.

STEP 1. Preheat the oven to 350 F. Line a cookie sheet with parchment paper.

STEP 2. Mix together the peanut butter, egg and sugar substitute in a mixing bowl.

STEP 3. Roll the cookie dough into 1 inch balls and arrange in rows on the baking sheet. Flatten the cookies with the back of a form, making a criss-cross shape on top of each cookie.

STEP 4. Bake cookies for about 12 minutes. Let them cool on the baking sheet for 2 minutes before transferring to a wire rack to cool completely.

The hardest part is waiting for the sugar free peanut butter cookies to cool! The sweet peanut-y aroma as these cookies bake is almost impossible to resist.

TIP: The cookies will be soft when you first take them out of the oven. They continue hardening the longer they cool. Be careful not to over bake!

Sugar Substitute Suggestion

Choosing the right swap for your sugar makes all the difference in this peanut butter cookie recipe. The sugar substitute should be granulated, like regular white sugar. Do not use liquid or powdered sweeteners!

  • Stevia – it’s what I used
  • Granulated Monk Fruit – I haven’t yet tested this recipe with it, but plan on doing so in the future.
    If you use it to make this recipe, I’d love to hear what you think, so leave me a comment below.

These natural sugar free sweeteners mimic the texture and chemical make up of real sugar remarkably well. Unlike artificial sweeteners, they also tend to leave less of a “chalky” or “chemical” aftertaste.

That said, if you love baking with sweeteners like Splenda (sucralose), they are a great option for these 3 ingredient sugar free cookies!

What kind of peanut butter is best for cookies?

To make this recipe truly sugar free, use a creamy natural peanut butter with no added sugars. They will be a bit more crumbly than peanut butter cookies made with shelf-stable peanut butter.

If you’re not totally avoiding sugar, you can also make these cookies with a standard shelf creamy peanut butter (like Jif). It won’t be totally sugar free, but it’ll still have WAY less sugar than your average cookie!

Easy Peanut Butter Cookies with Stevia!

Are these cookies gluten free?

Yes, they are! These easy sugar free cookies are also low carb, keto friendly and dairy free. Hip hip hooray!

Note: If you are baking for someone with celiac disease, make sure you check the label on your peanut butter to ensure cross contamination with gluten products.
