How to make low-carb peanut butter cookies
It only takes about 5 minutes to mix up the batter, and then you’ll have a delicious treat ready to be enjoyed throughout the week!
You can see how I make them in this short video or read the step-by-step instructions below.
Step 1: Preheat oven to 350F (180°C) and line a cookie tray with baking paper. Set aside.
Step 2: Add the erythritol to a Nutribullet or blender and blend until powdered. Set aside. If using a confectioner’s low-carb sweetener, you can skip this step.
Step 3: Add all of the ingredients into a medium mixing bowl and mix until a smooth, glossy dough forms.
Step 4: Roll about 2 tbsp of dough between your palms to form a ball, then place on the prepared cookie tray. Repeat until all dough has been used. You should end up with 12-14 cookies.
Step 5: Use a fork to flatten the cookies, creating a criss-cross pattern across the top.
Step 6: Bake the cookies for 12-15 minutes.
Step 7: Remove from the oven and allow to cool for 25 minutes on the baking tray, then transfer to a cooling rack for another 15 minutes.
Now your peanut butter cookies are ready to enjoy!
Give your cookies time to cool
Even though your cookies are going to smell amazing when you take them out of the oven, resist the urge to sample one right away! Make sure you give them the full amount of time to cool on the baking tray and the cooling rack.
Because this recipe does not contain any flour, the cooling step is crucial to allow the cookies to firm up. The longer they are able to cool, the better the texture will be. You don’t want them to fall apart when you go to eat them!
Be patient with these. I promise, it’s worth it 🙂
Customizing the recipe
There are a few different variations for this recipe that you can try. Don’t be afraid to get creative!
We all know that peanut butter and chocolate are a classic combination. For a little extra sweetness, add in some sugar-free chocolate chips. Or, for a truly decadent treat, half-dip each cookie in melted sugar-free dark chocolate. This takes the cookies to a WHOLE new level! Just be sure you allow the cookies to fully cool before dipping.
To give the cookies a nutty texture, try using crunchy peanut butter instead of creamy.
You can also swap out the peanut butter altogether and use a different nut butter. Cashew or almond would work well in this recipe!
Keep in mind that the peanut butter will add the most taste to the cookies, but if you prefer not to use it or have an allergy, any nut butter will do.
I recommend storing your cookies in an airtight container in the refrigerator for up to a week. They will stay fresh, soft, and delicious!
For longer storage, you can freeze them instead and enjoy for several months.
