Soft, chewy, and perfectly sweet without refined sugar. These flourless keto cookies deliver rich peanut butter flavor in every bite. Simple ingredients, big comfort, and ready in minutes.

If you’re craving something sweet but want to keep it simple and low-carb, these 3 Ingredient Sugar Free Cookies are about to become your new favorite treat. They’re soft in the center, lightly crisp on the edges, and packed with rich peanut butter flavor in every bite.

Your Recipe Guide

Made without flour and without refined sugar, these cookies are naturally gluten-free and perfect for anyone following a keto or low-carb lifestyle. The texture is tender and slightly chewy, with that classic fork-pressed cookie look that feels nostalgic and comforting. Best of all? They come together in minutes with pantry staples.

Is This Good for Weight Loss?

Yes — when enjoyed in moderation.

These cookies are made with low-carb, keto-friendly ingredients like natural peanut butter and a sugar-free sweetener. They contain minimal net carbs and no refined flour, which makes them more suitable for a low-carb or keto eating plan.

Because they’re rich in healthy fats and protein, they can feel more satisfying than traditional sugar-loaded cookies. Just remember portion control still matters — even keto desserts are treats.

Is This Keto or Not? And Why?

Yes, this recipe is keto-friendly when made with natural peanut butter (no added sugar) and a keto-approved sweetener. Each cookie contains low net carbs because there’s no flour and no traditional sugar involved.

Peanut butter provides healthy fats and some protein, while the sugar-free sweetener keeps the carb count low. As long as your peanut butter has no added sugar and you measure portions properly, these cookies easily fit into a standard keto lifestyle.

What is 3 Ingredient Sugar Free Cookies?

These cookies are a minimalist version of classic peanut butter cookies. Traditionally, peanut butter cookies include flour and sugar, but this simplified version removes both.

They rely on peanut butter for structure, eggs for binding, and a keto sweetener for sweetness. The result is a naturally gluten-free, flourless cookie that’s quick to mix and bake. It’s a modern low-carb twist on a beloved American classic.

Why This Recipe is Special:

Uses only three simple ingredients
Completely flourless and gluten-free
Keto-friendly and low-carb
Ready in under 20 minutes
Naturally rich and satisfying

Key Ingredients:

Peanut Butter

I always use natural peanut butter with no added sugar. It gives these cookies structure, richness, and that classic nutty flavor. For keto, check the label to keep net carbs low.

Egg

The egg binds everything together and helps create that soft, slightly chewy texture. It also gives the cookies lift while baking.

Sugar-Free Sweetener

I prefer a granulated erythritol or monk fruit blend. It sweetens the cookies without adding carbs and helps create a lightly crisp edge.

Common Mistakes to Avoid:

Using peanut butter with added sugar — it increases net carbs and affects keto suitability.
Overbaking — these cookies continue to firm up as they cool.
Skipping parchment paper — they can stick easily.
Not mixing thoroughly — uneven mixing leads to crumbly cookies.

Required Equipment:

Mixing bowl — keeps everything combined easily in one place.
Spoon or spatula — helps blend thick peanut butter smoothly.
Baking sheet — provides even baking.
Parchment paper — prevents sticking and makes cleanup simple.
Fork — creates the classic crisscross cookie pattern.

Caleb’s Recipe Tips

If your peanut butter is too thick, microwave it for 10–15 seconds. It makes mixing much easier and gives smoother dough. Trust me, I’ve learned this the hard way!
Slightly underbake the cookies. They may look soft in the center, but they firm up perfectly as they cool.
For extra flavor, add a pinch of sea salt on top before baking. It balances the sweetness beautifully.
Chill the dough for 10 minutes if it feels sticky. This helps the cookies hold their shape better in the oven.
Press gently with the fork. Too much pressure can flatten them too much and make them thin and crispy instead of soft.

Storage Instructions:

Store cooled cookies in an airtight container at room temperature for up to 3 days.

For longer storage, refrigerate in a sealed container for up to 1 week.

To freeze, place cookies in a freezer-safe container with parchment between layers. They stay fresh for up to 2 months. Thaw at room temperature before serving.
