These low carb and keto-friendly peanut butter cookies are crispy on the outside, full of peanut butter flavor and studded with chocolate chips. It’s an easy, one-bowl recipe so that you can quickly whip up a batch of these whenever the craving hits for a cookie.
It’s almost the weekend so time for a treat. These cookies are super easy to make. They take about ten minutes to prepare and ten minutes to bake.
If you’ve been baking a long time, you’ve likely come across flourless peanut butter cookie recipes before. The most basic recipe is just 3 ingredients, but I’ve always added a few more ingredients to mine to turn them into peanut butter chocolate chip cookies. Recently, I took my flourless peanut butter chocolate chip cookies recipe that I have been making for years and made a few tweaks to make them keto-friendly.
- Unsweetened Natural Creamy Peanut Butter- Make sure to use natural peanut butter, otherwise your dough will be too dry. I like to start with a fresh jar to make sure the peanut butter hasn’t dried out at all.
- Egg- The egg acts as a binding agent and reacts with the peanut butter to form a cookie when baked.
- Baking Soda- Baking soda will help the cookies rise, spread and puff up so that they look like traditional cookies.
- Vanilla- Like with most cookie recipes, I like to add a splash of vanilla which helps to enhance the flavor of the cookies.
- Brown Sugar Alternative- I tested this recipe with a few different sugar substitutes and found that the brown sugar alternative produced the best results. It melts during baking and keeps the cookies moist and soft. Unlike traditional flourless peanut butter cookies which use a 1:1 peanut butter and brown sugar ratio, I found that for this keto version you only need half the sugar. Too much of the sugar alternative makes the cookies way too sweet and the dough becomes too dry to work with.
- Sugar Free Semi-Sweet Chocolate Chips- Chocolate chips will add some sweetness to the cookie batter and give the cookies some height as well.
Tips for Making Keto Peanut Butter Cookies
- Make sure to mix the peanut butter, egg, baking soda and vanilla first. Once you add the brown sugar, the dough will start to become dry and hard to mix.
- I don’t recommend adding more than 1/2 cup of brown sugar alternative. Adding too much will make the dough too dry and the cookies far too sweet.
- The dough may appear to be a little crumbly, but if you compact it into a ball, it should stick together.
- You need to press down on the dough balls before baking because they will not spread that much.
- Be careful not to overbake the cookies as it will also cause the cookies to dry out.
- Let the cookies cool completely on the baking sheet before attempting to remove them. This is very important. Cookies will be very soft when they first come out of the oven. If you try to remove them, they will fall apart. Once the cookies are cooled and set, they will be sturdy enough to hold and remove.
Keto Peanut Butter Chocolate Chip Cookies
- 1 cup unsweetened natural creamy peanut butter
- 1 large egg
- 1 tsp baking soda
- 1/2 tsp vanilla
- 1/2 cup sukrin gold brown sugar alternative not packed
- 1/2 cup Lily's chocolate chips divided
- Preheat oven to 350°F. Line two baking sheets with parchment paper or silicone baking mats.
- In a large bowl, add peanut butter, egg, baking soda and vanilla. Mix until everything is evenly blended and no egg streaks remain.
- Stir in brown sugar alternative. Your dough will start to firm up as you mix in the sugar and become a little dry and the sugar will not completely dissolve. This is fine. Just make sure it is evenly mixed into the dough.
- Stir in half of the chocolate chips.
- Using a 1.5 tbsp cookie scoop, scoop up cookie dough and then pack it into a compact ball. Even though the dough may appear to be a little dry, once packed together, it should form a solid dough ball. Place dough ball onto prepared cookie sheets, spaced about 1 1/2 inches apart.
- Press down on each dough ball so that it forms a thick disk. The cookies will not spread much during baking so your disk will be close to the final width of the cookie. Press a few chocolate chips on the surface of each disk.
- Bake cookies about 10-11 minutes or until tops and edges just start to turn a golden brown. Cookies will still be very soft but should have puffed up. Remove cookies from oven and let them cool completely on cookie sheets. Do not attempt to remove cookies before they are set because they will still be brittle and fall apart if you do. Once cookies are cooled and set, you should be able to easily remove them from the baking sheet.
- If you are okay with your cookies being less sweet, you can reduce the brown sugar further by 1-2 tbsp. Do not reduce too much otherwise your cookies will be powdery and brittle.
- I used sukrin gold brown sugar alternative.* I believe these cookies will also work with Swerve brown sugar alternative which is similar. I have not tested this with other brown sugar alternative brands. I do recommend you stick with a brown sugar alternative and not another sugar substitute because other sugar substitutes will likely change the texture of the dough.
- Do not pack the sugar when measuring it. Adding too much sugar will make the cookies too sweet and the cookie dough will be too dry.
- Use natural creamy peanut butter, otherwise your dough will be too dry. I always like to start with a fresh jar to make sure the peanut butter has not dried out.
- Your dough may look crumbly when you're done mixing, but it should form a solid dough ball when you compact it and squeeze it together. If for some reason your dough is just too dry to work with, it is likely your peanut butter. You can try adding 1-2 tbsp of melted butter to the batter.
