Here’s another healthy dessert recipe! Peanut butter cookies are my favorite cookie! Years ago, I was obsessed with the Peanut Butter Dream cookie from Panera. They got rid of and I have been secretly waiting for it to surface again.

It hasn’t and maybe that means I should come up with my own recipe. One that is easy on the waistline!

What Type of Sweetener to Use

I use granular organic monkfruit. It has zero calories and zero net carbs and won’t spike your blood sugar. It also measures 1:1 like refined sugar, which makes it easy to convert a lot of recipes. You can find it here and use Discount Code STAYSNATCHED to save.

It does also contain erythritol. Erythritol is naturally found in some fruits and vegetables, and even some fermented food. Your body processes it a lot differently than other sugar alcohols. Bottom line, it’s a lot less gassy. 

If you choose to use a zero-calorie sweetener other than this, like stevia, you will have to convert this serving into a much smaller allotment.

Is Peanut Butter Keto?

I see this asked often. Natural peanut butter is very low in carbs and it’s high in fat which could make it great for the keto diet. Peanut butter can sometimes lead to inflammation.

So those who are using keto for anti-inflammatory reasons may wish to omit peanut butter from their diet. Almond butter is a suitable substitute.

How to Make Keto Peanut Butter Cookies

  1. Preheat the oven to 350 degrees.
  2. Combine natural peanut butter, sweetener, egg, and vanilla in a mixing bowl. Mix.
  3. Line a baking sheet with a silicone baking mat
  4. Create balls using the cookie dough. Flatten each ball with a fork in a crisscross motion.
  5. Bake.
  6. Cook the cookies prior to serving.

How Long to Bake and How to Tell They are Done

The cookies will need 12-15 minutes to bake. Keep a watchful eye as oven temperatures vary highly based on altitude and other factors.

Allow the cookies to cool for 1-2 minutes on the cookie sheet before removing. The cookies will need to firm up BEFORE you handle them. If you handle them too soon they will crumble. Use your judgment on timing if 1-2 minutes does not appear to be enough.

How to Store Them/How Long Are They Good For?

I like to store the cookies in sealable plastic bags for up to a week. The cookies will get softer as time goes on, so keep that in mind.

Freezer Tips

You can freeze these (tightly sealed) for up to 6 months.

Recipe Update
I added to Monkfruit Chocolate Chips to the recipe and the cookies were amazing! 

These chocolate chips are keto-friendly and sweetened with monkfruit. 60 chocolate chips is equal to 1 gram net carbs. Great macros!

Prep Time 10 minutes
Cook Time 15 minutes
Total Time 25 minutes
Servings 15 cookies
Calories 102kcal

Ingredients

  • 1 cup natural, unsweetened peanut butter I use Smuckers. Truly, natural peanut butter should have oil and require you to stir. You can also use nut butters, such as almond.
  • 1/2 cup sweetener (Use discount code STAYSNATCHED to save 15%)
  • 1 egg
  • 1 teaspoon vanilla extract

Instructions

  • Preheat oven to 350 degrees.
  • Combine the ingredients in a large bowl. Stir to mix well.
  • Make 12-15 balls using the cookie dough. (If you prefer really flat cookies you should aim for 15. Slightly thicker cookies will result in about 12 cookies). An ice cream scoop works well, so does rolling the balls in your hands.
  • Line a cookie sheet with silicone baking mats. You can also use parchment paper. Place the cookie dough on the cookie sheet. Make sure the cookies do not touch.
  • Use a fork and press down on each ball of cookie dough. Create crisscross imprints in the cookie dough to flatten the balls.
  • Bake for 12-15 minutes until the cookies are golden brown. Mine were ready around 13 minutes.
  • Remove the cookie sheet from the oven. Allow the cookies to cool for 1-2 minutes on the cookie sheet before removing. The cookies will need to firm up BEFORE you handle them. If you handle them too soon they will crumble. Use your judgment on timing if 1-2 minutes does not appear to be enough.
  • After 1-2 minutes place the cookies on a cooling rack to fully cool.

I typically use unsweetened almond milk for everything. It pairs wonderfully with these cookies and is keto friendly.
If you would like cookies with chocolate chips use 1/4 cup and simply fold in the chocolate chips right before you mold the cookie dough into balls.
Add 3 scoops (50 grams) of protein to make them protein cookies. I use this collagen.

Saw this recipe and immediately made it once I saw that I had the ingredients. I used brown sugar substitute instead and added 2 scoops of vanilla collagen. I enjoyed the taste of the brown sugar as well, I would reccomend it. These are so easy, you can make them quickly after dinner and they taste great.

Super simple and tastes like a cookie should! A little curious about the way it give sa cool effect in the mouth though, even though their still slightly warm to room temp. A result of the monk fruit sugar maybe?

I made these cookies on a whim and they are amazing! Took all of 30 minutes start to finish, half of which was baking and cooking. So so good! Also added some collagen hydrolysate for a small boost of protein - turned out great. (they were obviously a bit thicker than normal, but still just as delicious!)
