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. Put the ingredients in your mixing bowl and then just mix to combine. I mix them up in my Kitchenaid mixer till it’s just combined.

Using a tablespoon for measurement I roll the cookie dough into a ball and place them on a parchment sheet lined cookie sheet.  Sprinkle with some Splenda and then press with a fork.

Bake them in a preheated 350-degree oven for 10-13 minutes.

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
