This recipe makes one of the simplest low carb peanut butter cookies you’ll ever enjoy! I love the flavor and texture. My personal favorite way to enjoy them is with some Greek yogurt for breakfast or as a quick pick up in the afternoon!

Why choose flourless peanut butter cookies?

Low carb peanut butter cookie recipe ingredients

Our three primary ingredients for this recipe are:

  1. Creamy peanut butter
  2. An egg
  3. Chopped pistachios

Ingredient #1: Peanut butter

Peanut butter contains all three of my favorite blood sugar friendly nutrients: fat, fiber, and protein. It’s the reason these cookies have 6g of protein each! And, it’s not only delicious but it’s a low cost way to add plant based fat and protein to a variety of other dishes too.

Does natural peanut butter work in cookies?

You can use natural peanut butter in this recipe if you choose to, but make sure it’s stirred together really well. If the oil has started to separate, the cookies may not be able to form together well.

Which peanut butter has the least amount of carbs?

If you’re looking to make low carb peanut butter cookies with the least amount of carbs possible, you should choose a peanut butter that has no added sugar. However, if you want your cookies to be slightly sweet, you can use a sweetened peanut butter. Relatively speaking, they’ll still be low in carbs.

Ingredient #2: Eggs

The egg serves as our binder for these cookies and helps them bake together. Eggs have no carbohydrate, and the one egg does contribute a small amount of protein to each cookie in this recipe.

Ingredient #3: Pistachios

Pistachios, like peanuts and peanut butter, contain my favorite blood sugar friendly nutrients: fat, fiber, and protein. Personally, I love the texture and color variety that they give these cookies too!

Are these sugar free peanut butter cookies?

Peanut butter, even if it’s unsweetened, does have some naturally occurring sugar, so each cookie has 1g sugar.

  1. Hi Would it be possible to use walnuts or pecans in this recipe as I’m on the low FODMAP diet and generally don’t tolerate pistachios cashews, or large amounts of almonds ie more than 10. Thanks

  2. 5 stars
    I tried these last night but it felt too late to kick the oven on so I put them in the air fryer and it totally worked! I LOVE the simplicity and how quickly these worked up!
