How to make low-carb peanut butter cookies

That’s it! It only takes three ingredients to make these easy low carb cookies. I like using Splenda as my sweetener, but you could use other low-carb sugar substitutes if you prefer.

Preheat and Prep:

Start by preheating your oven and lining a baking sheet with parchment paper. This ensures easy cleanup and prevents sticking.

Mix It Up:

In a mixing bowl, add the ingredients. Mix until a dough forms. Feel free to throw in some sugar-free chocolate chips for an extra layer of decadence! I love using my Kitchenaid mixer for all my cookie dough.

Scoop and Shape:

Using a cookie scoop or your hands, form the dough into evenly sized balls and place them on the prepared baking tray. Flatten each ball slightly with a fork, creating the classic crisscross pattern.

Bake to Perfection:

Pop your cookies into the preheated oven and let the magic happen. In just 10-13 minutes, you’ll be greeted by golden brown perfection. Keep an eye on them to avoid over-baking.

Cool and Enjoy:

Allow your low-carb peanut butter cookies to cool on the baking sheet for a few minutes before transferring them to a cooling rack. This step ensures they set properly, resulting in a chewy and delicious texture. Now, it’s time to savor the fruits of your baking adventure!

Customizing the recipe

If you like a chewy cookie texture, you can add 1/2 cup of almond flour and an additional egg to this recipe. Coconut flour will work too.

If you want some crunch, you can add some chopped, salted peanuts to the top of your cookies before you bake them.

If you love chocolate with your peanut butter, add some mini chocolate chips to the peanut butter cookie recipe.

I hope you love them as much as we have in all the varieties we’ve tried over the years.


  1. My husband and I have been doing a 30 day low carb challenge (we just challenged ourselves to do 30 days, lol). We’re nearing the end, but he’s been thinking of continuing on after the 30 days, so these would be a perfect sweet treat for him. We don’t keep splenda in the house but may make a special trip to the store for some to try this. I’ve made a really similar recipe with sugar, but haven’t tried the low carb version!

  2. Oh yum! I bet these are dangerous! I love that they are so easy… my kids are crazy for peanut butter so I think I’m gonna have to make them soon! Thanks! #SuperSaturday
