Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Natural peanut butter (no sugar added)
Granulated keto sweetener (like erythritol or monk fruit blend)
Egg
Baking soda
Vanilla extract
Salt (if peanut butter is unsalted)
Sugar-free chocolate kisses or chocolate chunks

Directions

I preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, I stir together the peanut butter, sweetener, egg, baking soda, vanilla, and salt (if needed) until well combined and smooth.
I scoop the dough into tablespoon-sized balls and place them on the prepared baking sheet, leaving a little space between each one.
I bake the cookies for 8–10 minutes, just until they’re set and lightly golden on the edges.
As soon as they come out of the oven, I gently press a sugar-free chocolate kiss or chunk into the center of each cookie.
I let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Variations

Sometimes I use almond butter or sunflower seed butter instead of peanut butter for a nut-free version. I’ve also added a sprinkle of sea salt on top for a sweet-salty contrast. If I don’t have sugar-free chocolate kisses, I press a square of dark chocolate or a few sugar-free chips into the center instead.

Storage/Reheating

I store these cookies in an airtight container at room temperature for up to 5 days, or in the fridge for longer freshness. They also freeze well—either baked or unbaked. To freeze unbaked dough, I roll them into balls and freeze, then bake straight from frozen, adding an extra minute to the bake time. Keto Peanut Butter Blossoms

FAQs

Are these cookies really keto?

Yes. As long as I use unsweetened peanut butter and a keto-friendly sweetener, each cookie stays low in carbs and fits within a keto lifestyle.

Can I use crunchy peanut butter?

Yes, and I’ve tried it—it gives the cookies extra texture. Just make sure it’s sugar-free and natural.

Why are my cookies crumbly?

If the dough seems too dry, I add a tiny splash of almond milk to bring it together. Letting them cool completely also helps them firm up properly.

Can I make these without eggs?

Yes, I’ve used a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water) and they still hold together well.

What chocolate is best for keto blossoms?

I like using sugar-free chocolate kisses or 90% dark chocolate squares. Lily’s brand or ChocZero are great options for keeping things keto.

Conclusion

Keto peanut butter blossoms are one of my favorite ways to enjoy a classic cookie without the carbs. They’re soft, satisfying, and perfect for holiday trays or everyday cravings. With just a handful of ingredients and no flour needed, these cookies prove that delicious can still be simple—and totally keto-friendly.
