If peanut butter and jelly take you straight back to childhood lunches, you’re not alone. But if you’re on a low-carb or keto diet, those nostalgic flavors probably feel off-limits.
Good news: these PB&J cookies let you relive the magic—without the sugar crash.
This keto-friendly spin keeps the comfort, ditches the carbs, and somehow still feels indulgent.
What Makes These PB&J Cookies Keto-Worthy?
Regular peanut butter and jelly cookies rely on sugar-packed jam, flour, and sweeteners that spike blood sugar. This version flips the script.

It swaps in powdered erythritol or monk fruit for sugar, skips the flour entirely, and uses low-sugar or homemade jam made with real berries.
The result? A chewy, satisfying cookie that hits all the nostalgic notes while keeping your carb count in check. Even better, each bite delivers that familiar contrast of nutty richness and fruity sweetness—without the guilt.
Sweet Meets Salty in Every Bite
The magic is in the balance. That slightly salty, creamy peanut butter base meets a little dollop of berry jam—usually strawberry, but raspberry works beautifully too.
You end up with a cookie that doesn’t scream “dessert,” but rather gently nudges your sweet tooth. Plus, the high-fat content keeps you full longer, making these more than just a treat—they’re practically a mini meal.
Quick, Easy, and Great for Batch Baking
Another reason to love these? They’re ridiculously easy to throw together. A few pantry staples, one mixing bowl, and about 20 minutes is all it takes. No fancy equipment, no waiting around.
These cookies are also a dream for keto meal preppers. They store well in an airtight container for several days, and if you freeze a batch, they thaw beautifully. Perfect for those “just one bite” cravings that sneak up mid-afternoon.
Personalize Your PB&J Cookie Game
The base recipe is great, but the fun really starts when you make it your own. Keto baking is super flexible, and these cookies are no exception.
Here are some simple swaps and upgrades:
- Try a different nut butter: Almond or cashew butter can bring a new flavor profile (and might be gentler if peanut butter doesn’t sit well with you).
- Mix up the jam: Go for blackberry, raspberry, or even a homemade chia jam for texture and fiber.
- Flavor boosters: A splash of vanilla or a dash of cinnamon adds warmth.
- Go gourmet: Drizzle some melted sugar-free dark chocolate over the top for that fancy bakery vibe.
Small tweaks, big flavor upgrades.
Going Ultra Low-Carb? Here’s How to Dial It In
Even keto versions of PB&J can sneak in carbs if you’re not paying attention to ingredients. A couple of easy tips:
- Pick the right peanut butter. Skip the jars with added sugar or palm oil. The label should just say “peanuts” and maybe salt.
- Make your own jam. Combine fresh berries with a keto-friendly sweetener and simmer it down. It’s quick, tasty, and way cleaner than store-bought options.
Controlling your ingredients means you control your macros—without sacrificing taste.
A Feel-Good Treat You Can Share (Or Not)
Whether you’re prepping a sweet snack for the week or baking a batch to bring to a get-together, these cookies check all the boxes. They’re easy to pack, easy to share, and even non-keto folks will ask for the recipe.
Try them with a cup of coffee in the morning, a scoop of Greek yogurt, or as a quick pick-me-up when the afternoon slump hits. However you enjoy them, they’re proof that comfort food and keto can coexist.
You don’t have to give up on your favorites—you just have to reimagine them. And in this case, that reimagining tastes pretty amazing.
