Easy Keto Cookie Recipe

This low calorie cookie recipe is an update from my original Keto Peanut Butter Banana Cookies. You may have sworn off bananas since being on a keto diet, but if you are like me, someone in your household may still be eating bananas. And when there are bananas in the house, there always ends up being one or two left that are too ripe for consumption. That is why I have come up with easy keto recipes like this Chocolate Peanut Butter Banana Blondies, Keto Banana Bars Recipe With Brown Butter Frosting and this foolproof Keto Banana Swiss Roll Cake

These 50 calorie cookies contain under 1 gram of sugar each and are super easy to make. Clocking in at just shy of 70% fat, this easy keto cookie recipe is one that will quickly become a family favourite!

Ingredients and Substitutions

There are no "funny" ingredients in this low calorie cookie recipe. Only 5 main ingredients (plus vanilla, baking soda and salt), these sugar-free gluten-free cookies are super easy to make!

Peanut butter - I used a natural organic peanut butter from Thrive Market. You can use any style of peanut butter; however, you may want to adjust the amount of sweetener and/or salt as the peanut butter I wrote this recipe for did not have any added sweetener or salt.

Sweetener - I used Lakanto Golden for these cookies to give them a slight caramel taste. You can use any type of sweetener but remember that if you use allulose, the cookies may brown more than these pictures demonstrate.

Almond flour - You will need ¼ cup of almond flour. Make sure that it is super-fine almond flour and not almond milk. You can probably replace the almond flour with 2 tablespoons of coconut flour. I have not tried this version yet so if you do, let me know how it turns out!

Flaxseed meal - I started to use flaxseed meal in my cookie recipes after having falling in love with my Easy Keto Monster Cookies. Flaxseed meal keeps these cookies nice and gooey inside and also help the cookies to hold their shape. You will not even taste the flax meal so do not worry if you do not care for it! Make sure that you use flaxseed meal and not whole flax seeds.

Egg - I large egg is going to be used in this recipe to help to bind the ingredients. Make sure that the egg is at room temperature.

Vanilla - You can't make keto peanut butter cookies without vanilla! Feel free to use either homemade pure vanilla or imitation vanilla.

Baking Soda - Baking soda not only gives these cookies a little rise but also helps to brown them ever so slightly.

Pinch of Salt - You may or may not need to add a pinch of salt. My peanut butter was not at all salty so I added just a pinch. However, I would take a small spoonful of the cookie dough and decide if you want to add some salt.

Sugar-free Chocolate Chips - You do not have to add chocolate chips to this recipe but there is something sinfully delicious when you combine peanut butter and chocolate!

Instructions

Just like you do not need any fancy ingredients, you also don't need any fancy equipement when making these keot peanut butter cookies!

Hint: If you do not let these low calorie cookies chill for at least 4 hours, they will not be able to be formed into cookies so make sure to plan to leave these cookies overnight or for at least 4 hours.

Substitutions

You can make some substitutions but just be aware that then may no longer be 50 calories cookies if you change the ingredients!

• Peanut butter - instead of peanut butter, you can use almond butter, sunflower seed butter or tahini.
• Brown Sweetener - use any type of sweetener in this recipe. Just be aware that all keto sweeteners have different levels of sweetness so you may need to adjust the recipe
• Flaxseed meal - If you have flax seeds, you can simply grinding them into flaxseed meal. Or, you can always use oat fiber or more almond flour instead.

Although these are sugar-free gluten-free cookies, you can always change the ingredients and use real brown sugar for a low calorie cookie that is still gluten-free but not sugar-free.

Variations

These Keto Peanut Butter cookies are such a great cookie base that can be used in so many different ways to create a ton of different flavoured cookies!

• Chocolate - replace some of the almond flour and flaxseed meal with some unsweetened cocoa powder. Add some sugar-free chocolate chips for a double chocolate version!
• Double Decker - Spread some homemade keto espresso nutella between 2 cookies for a sandwich cookie
• Snickerdoodle - Add some cinnamon and then roll each cookie in some sugar-free cinnamon for a snickerdoodle twist.

FAQs

Do I have to use a specific type of sweetener?

I am fairly certain that any type of sweetener will work for these cookies. 

I used an erythritol-based sweetener which added a little crunchiness to these cookies once they have cooled.

Can I add anything to these low carb cookies?

Absolutely!

Feel free to add some chocolate chips or even white chocolate chips.  You could even spread some Sugar-Free Cream Cheese Frosting on the cookies and decorate them however you please.

What is the texture of these cookies?

These cookies are soft in texture and need to be cooled completely before removing them from the cookie sheet. The cookies will continue to harden as they cool.

How long will these keto cookies last?

These cookies should be stored in an airtight container once fully cooled. They should last about 5-7 days.

Can I freeze this cookie dough?

You can shape the cookies and then freeze the cookie dough. To bake the cookies, simply add a couple of extra minutes to the baking time.

What size cookie scoop did you use to make these 50 calorie cookies?

I used a ⅓ tablespoon (also called a 1 tsp) cookie scoop to get the right size of cookies. You should be able to get about 28 cookies. For a visual reference, these cookies are the approximate size of High Key Chocolate chip cookies. You can always make these cookies larger if you want but you may need to increase the baking time by a minute or two.
