Delicious flourless peanut butter cookies made with 5 simple ingredients! This easy recipe is gluten, grain and dairy free. And filled with that nostalgic, irresistible peanut butter flavor you know and love. The perfect treat for kiddos and adults!
Peanut butter cookies are a timeless classic. These flavorful cookies never go out of style and are always recognized by the traditional criss-cross pattern. They’re one of my very favorite cookie varieties (so much so that I even make a DIY dog treat version for my pup, lol!) and I wanted to make them a bit healthier than your average peanut butter cookie.
These peanut butter cookies turned out so tasty! In fact, you won’t even miss the flour and butter.
Flourless peanut butter cookies are the perfect guilt-free treat for the holidays, family gatherings or an after school snack. I’m bringing this recipe to you just in time for cookie baking season and it will be a crowd pleasing addition to your Christmas cookie tray!
Because these healthy peanut butter cookies contain no butter or flour, the delicious peanut butter flavor really shines. Plus, they use just 5 key ingredients! Here’s what you’ll need to make them:
- Natural peanut butter – I used all-natural salted peanut butter. Creamy or chunky will work. If you happen to be allergic to peanut butter, almond butter will also work well.
- Egg – One egg will add the perfect amount of structure, stability, and richness.
- Sweetener – I like to use either monkfruit or coconut sugar to sweeten these healthier peanut butter cookies. Feel free to swap with brown sugar or granulated sugar, though, if that’s what you’d like.
- Vanilla extract – For a boost of delicious flavor!
- Dark chocolate – I couldn’t resist dipping these cookies into dark chocolate once they were cooled. Feel free to skip this extra step and enjoy the peanut butter cookies as-is, sans the chocolate.
- Coconut oil – For mixing with the optional dark chocolate.
How to Make Flourless Peanut Butter Cookies:
The best part about these healthy peanut butter cookies is how easy they are to make. You only need one bowl, no mixer or chilling the dough required. You’ll have warm cookies in under 20 minutes!
- Prep – Preheat your oven to 350 degrees F and line a rimmed baking sheet with parchment paper, a silicone mat or lightly spray with cooking spray.
- Combine ingredients – In a large bowl, stir the peanut butter, egg, monkfruit or coconut sugar and vanilla together until fully combined.
- Roll balls of dough – Scoop a heaping tablespoon of dough and roll it to form balls, then flatten into a disc-like cookie shape. Place on a baking sheet and repeat with the remainder of the dough.
- Criss-cross pattern – Using a large fork, flatten cookies slightly, then turn fork in the opposite direction and flatten just slightly again.
- Bake – Place cookies in the oven for 10 minutes or until cookies just start to look brown. Allow cookies to cool on the baking sheet for about 5 minutes before transferring to a wire cooling rack.
- Dark chocolate dip – If you’d like to add the dark chocolate coating to half of the cookies, melt chocolate in the microwave or in a double boiler. Stir coconut oil into melted chocolate. Dip one-third or half of the cookie in the chocolate and place back on the cookie sheet. Sprinkle with a bit of flaky sea salt and repeat until you’ve worked through all of the cookies. Place the baking sheet in the refrigerator for one hour and until the chocolate is set.
Why do peanut butter cookies have a criss-cross pattern?
The crosshatch pattern, made with a fork, on the top of peanut butter cookies is a classic trait of nearly all peanut butter cookies. And isn’t just for looks!
Peanut butter cookie dough doesn’t spread much when baking, so pressing down on the cookie dough helps to flatten the cookies a bit, so they bake up perfectly. As an added plus, you never need to ask which cookies are peanut butter!
It’s very easy to make the criss-cross pattern. Simply, use the tines of a fork to gently press it into the top of the cookie, then repeat and make the fork imprint perpendicular to the first. Easy peasy!
What makes flourless peanut butter cookies healthy?
- There’s no flour, so these cookies are naturally gluten free and grain free.
- They are dairy free because there’s no butter needed. However, if you’re adding the dark chocolate, be sure to buy dairy-free chocolate.
- No need to add oil – the peanut butter keeps these cookies moist with natural oils and healthy fats.
- For a cookie, they are high in protein, thanks to peanut butter and eggs. Each cookie is filled with 7 grams of protein!
Customize Your Peanut Butter Cookies
These flourless peanut butter cookies are fantastic as-is, but sometimes it’s fun to change things up. Here’s some ways to get creative and experiment with your favorite ingredients!
- Nut butter – Feel free to use any nut butter you’d like. Almond butter is also a great choice. You could even use homemade peanut butter or almond butter!
- Mix-ins – Have fun with your favorite add-ins like nuts, chocolate chips or a chocolate drizzle! You can also omit the chocolate to keep them strictly peanut butter.
- Refined sugar free – To make these cookies refined sugar free, use monkfruit or coconut sugar and omit the dark chocolate coating.
- Holiday cookies – Drizzle with or dip the cookies into white or dark chocolate and then add holiday sprinkles or colored sugars over the melted chocolate.
Storing & Freezing
- To store: Keep these cookies in an airtight container in the fridge for up to about 1 week.
- To freeze: Once the cookies are completely cooled, transfer them to an airtight container or freezer-safe bag and store them in the freezer for up to 2 months. When you’re ready to enjoy, thaw at room temperature!
