Ingredients You’ll Need

Simple, pure ingredients really shine in this recipe, letting the peanut butter’s hearty flavor and creamy texture take center stage. Each component brings something special to your cookies, from tenderness and lift to that irresistible cookie snap we all crave.

• Natural peanut butter: Unsweetened and unsalted peanut butter ensures a pure, nutty flavor and keeps these cookies keto-friendly and deliciously moist.
• Granular erythritol or preferred keto sweetener: This sugar substitute adds the perfect hint of sweetness without the carbs or the spike in blood sugar.
• Large egg: The secret to binding everything together and adding just enough structure to hold these cookies’ classic shape.
• Vanilla extract: Just a splash boosts the aroma and adds subtle depth that makes peanut butter cookies so irresistibly tasty.
• Pinch of salt: A dash sharpens all the flavors, pulling together the nuttiness and gentle sweetness into perfect balance.

How to Make Keto Peanut Butter Cookies

Step 1: Prep Your Oven and Baking Sheet

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper — this little step keeps your cookies from sticking and makes for effortless cleanup. Prepping your equipment before mixing lets you focus on the dough without missing a beat.

Step 2: Mix the Dough

In a medium mixing bowl, combine the peanut butter, granular erythritol, egg, vanilla extract, and a pinch of salt. Stir everything together until you have a thick, cohesive dough. It will come together easily, thanks to the egg binding everything and the creamy texture of the peanut butter.

Step 3: Shape the Keto Peanut Butter Cookies

Using a tablespoon, scoop out even portions of dough and gently roll each into a ball between your palms. Place the balls onto your prepared baking sheet, leaving a little room for them to spread slightly during baking. This quick step guarantees cookies that bake up ultra evenly.

Step 4: Classic Crisscross Pattern

With the back of a fork, gently flatten each dough ball, pressing a crisscross pattern on top. Besides being a timeless peanut butter cookie tradition, this also gives the cookies their signature look and ensures a uniform thickness for that perfect bake.

Step 5: Bake to Golden Perfection

Slide your tray into the preheated oven and bake for 10 to 12 minutes, or until the edges are lightly golden and just set. The heavenly aroma is your cue that the magic is happening. Don’t worry if they look a little soft at first — they’ll firm up as they cool.

Step 6: Cool and Enjoy

Once done, let the cookies sit on the baking sheet for about five minutes before transferring them to a wire rack. This resting period allows them to finish setting up and ensures they don’t crumble. Now, all that’s left is to enjoy!

How to Serve Keto Peanut Butter Cookies

Garnishes

Give your Keto Peanut Butter Cookies a little extra flair by sprinkling them with a touch of flaky sea salt just before serving. For a fun twist, add a few chopped sugar-free chocolate chips or even a light dusting of additional keto sweetener for sparkle.

Side Dishes

Pair your cookies with a creamy almond milk latte, a hot cup of black coffee, or a chilled glass of unsweetened nut milk. The rich, nutty notes of the cookies are perfectly complemented by your favorite warm or cold beverage.

Creative Ways to Present

Stack your cookies high on a vintage cake stand for afternoon tea vibes, pack them in parchment-lined tins for gifting, or set out with sliced berries and whipped cream for a playful keto dessert board. However you serve them, they’ll be the star of the snack table.

Make Ahead and Storage

Storing Leftovers

Keep your Keto Peanut Butter Cookies fresh by storing leftovers in an airtight container at room temperature. They’ll stay delicious for up to five days, making them perfect for meal prepping a week’s worth of healthy treats or sharing with friends.

Freezing

To extend their life, pop cooled cookies into a freezer-safe bag or lidded container. They freeze beautifully for up to two months — just layer parchment between them to prevent sticking. Thaw a few whenever you need a quick low-carb indulgence.

Reheating

If you love a warm, just-baked cookie vibe, reheat your Keto Peanut Butter Cookies in a microwave for 7 to 10 seconds. Warming brings back that freshly baked aroma and soft center without sacrificing texture.

FAQs

Can I use almond butter instead of peanut butter?

Yes, you can swap the peanut butter for creamy almond butter to create a different but equally tasty keto cookie. Just make sure you’re using an unsweetened, unsalted variety for best results.

What does erythritol do in this recipe?

Erythritol provides the sweetness while keeping the recipe low in carbs and sugar. It mimics the texture of traditional sugar, ensuring your Keto Peanut Butter Cookies have just the right amount of crunch and chewiness.

How do I prevent my cookies from crumbling?

Letting them cool completely on the baking sheet before transferring to a rack is key! These cookies firm up as they cool. Moving them too soon may make them fall apart, so patience pays off.

Can I add extras like peanuts or chocolate chips?

Absolutely! For even more crunch or decadence, mix in 2 tablespoons of chopped peanuts or sugar-free chocolate chips to your dough before baking. It’s a fun way to customize every batch.

Are these Keto Peanut Butter Cookies gluten-free?

Yes! Since there’s no flour in this recipe, these cookies are naturally gluten-free and perfect for anyone watching both carbs and gluten intake.
