These super simple Keto Peanut Butter Cookies require only 5 simple ingredients. They're low-carb, gluten-free, low sugar, and a total treat!
I'm crazy for peanut butter cookies. Peanut butter is naturally sweet, which makes them perfect when you're looking for a low carb, sugar free cookie.
When I start craving something sweet, these cookies come in handy. They are crunchy on the outside, chewy and slightly soft on the inside, and are so simple and easy to make!
You can whip these up in minutes with only 5 ingredients, 5 minutes of prep, and 12 minutes in the oven, which means you'll have a low carb homemade peanut butter cookie in less than 20 minutes.
It's a fun and simple recipe to make with the kids, and requires only one bowl - which means easy cleanup too!
Tools and Equipment You'll Need
How to Make Keto Peanut Butter Cookies - Step by Step
Step 1: Preheat oven to 350 F. Line a baking sheet with parchment paper or a silicone mat. In a bowl, mix together the peanut butter, vanilla, egg, almond flour, and sweetener (if using - optional) until combined.
Step 2: Using your hands, roll 1 tbsp of dough into a ball and place on the baking sheet. Repeat with the rest of the dough.
Step 3: Using a fork, press down on top of each ball in opposite directions to create a crisscross pattern.
Step 4: Bake for 12-15 min until golden brown. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool a little more (about 10 minutes).
Step 5: Dip half of the cookie into the melted chocolate and then into the crushed nuts. Place back on the cooling rack until they are completely cooled down.
What makes these keto peanut butter cookies healthy?
- Low Carb: This recipe has only 3.7 net carbs per cookie and only 2.3 grams of sugar per cookie! Now that's a guilt-free treat you can feel great about eating.
- High in Protein: Thanks to the peanuts and almonds, each cookie has almost 6 grams of protein. Protein helps keep you fuller longer and your blood sugar stable.
- Healthy Fats and Nutrients: Peanuts are high in Folate, Vitamin E, Phosphorous and Magnesium. They are also rich in antioxidants and healthy fats.
Will kids enjoy these keto peanut butter cookies?
Yes! If you're making this for kids, I would try making it without the Monk Fruit / Erythritol and see how your kids like it. Mine devoured these cookies without the sweetener and asked for seconds! So you might discover that these cookies are sweet enough for your kids just the way they are!
Why do peanut butter cookies have fork marks?
Peanut butter cookie dough is much more dense than most other cookie doughs, which means that if you don't score them / press them with a fork, they won't spread as much on their own and won't bake evenly.
How do you store and keep these cookies?
- To store: Make sure the cookies cool completely, then store in an airtight container in the fridge for up to 5 days.
- To freeze: Let the cookies cool completely, then wrap each one in parchment paper and store in an airtight freezer container or zip-top bag in the freezer for up to 3 months.
- To reheat: Defrost the cookies at room temperature. To serve warm, just warm them in the microwave for 20-30 seconds.
What is the best keto-friendly peanut butter?
Make sure to look for peanut butters that have only two ingredients: Peanuts and Salt. Avoid peanut butters that have added sugars or oils in addition to just "peanuts, salt" on the ingredients list. I typically choose organic peanut butters that I find at my local grocery store.
Top Tips for Making the Best Keto Peanut Butter Cookies
- Make sure you use a no sugar added peanut butter (check out this healthiest nut butters guide)
- You don't have to use any sweetener because peanut butter, chocolate and almonds are already naturally sweet! Try this recipe without the sweetener first and add it in if you feel like you want a sweeter cookie.
- The cookies will work without the almond flour but I recommend it because it adds flavor and texture (and holds the cookies together better!)
- Make sure to press your cookies down with a fork so that they bake evenly.
- If you don't have peanut butter, you can use almond butter as a substitute, but then they are technically almond butter cookies 🙂
- I haven't tried this recipe with egg alternatives, but a flax egg should theoretically work.
