Easy 3-Ingredient Sugar-Free Peanut Butter Cookies | Savory Haven
Peanut butter cookies have been a beloved staple since the early 20th century, when peanuts became a cheap protein source for families. Over time, the classic recipe evolved, and today the sugar‑free version offers the same comforting nostalgia while fitting modern health goals. This recipe captures that heritage in a streamlined, three‑ingredient form, delivering the soft, chewiness you remember from grandma’s kitchen.

Why You'll Love It

  • - Only three ingredients, no pantry raid needed
  • - Naturally sweetened, low‑carb, and gluten‑free
  • - Soft, melt‑in‑your‑mouth texture every time
  • - Quick bake, perfect for spontaneous cravings

*"These cookies are the perfect balance of sweet and nutty—my family can’t get enough!"*

Essential Ingredient Guide

  • Natural peanut butter: Choose a creamy, unsweetened variety for smooth texture and authentic nutty flavor.
  • Erythritol or other sugar substitute: Provides sweetness without the spike; pack it loosely to avoid clumping.
  • Large egg: Acts as binder and adds a subtle richness; room temperature works best.
  • Sea salt (optional): A pinch enhances the peanut flavor and balances the sweetness.
  • Vanilla extract (optional): Just a dash adds depth without overpowering the nutty notes.
  • Butter (optional for richer taste): Melted butter can be folded in for an even softer crumb.

Complete Cooking Process

  • Ingredient Readiness:

    Measure the peanut butter, sweetener, and egg; let the egg sit at room temperature for a minute.

  • Flavor Development:

    Mix the three ingredients until a smooth, glossy dough forms, letting the sweetener dissolve.

  • Texture Control:

    Scoop dough onto a parchment‑lined sheet and gently flatten with a fork for classic criss‑cross marks.

  • Finishing Touches:

    Sprinkle a tiny pinch of sea salt on each cookie before they go into the oven.

  • Serving Timing:

    Let the cookies cool on the sheet for a couple of minutes; they firm up quickly and are perfect warm.

  • Pro Tips

    • Chill the dough for 10 minutes if the butter makes it too soft.
    • Use a silicone baking mat for even browning.
    • Don’t over‑bake; the cookies should look slightly underdone for a chewy center.
    • Store in an airtight container to keep them soft for days.

    I’ve found that a brief rest after baking lets the interior settle, so the first bite feels extra tender. Yeah, it’s those little pauses that make the difference, especially when you’re serving friends who love a soft bite. Also, feel free to experiment with a dash of cinnamon or a smear of almond butter for a twist—just remember to keep the sugar‑free promise.

Absolutely—there’s no flour involved, so it’s naturally gluten‑free.

Ingredients

Main Ingredients

  • 01 1 cup natural creamy peanut butter
  • 02 ½ cup erythritol (or preferred sugar substitute)
  • 03 1 large egg

Instructions

Step 01

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 02

In a medium bowl, stir together the peanut butter and erythritol until smooth; I like to use a wooden spoon for that gentle feel.

Step 03

Add the egg and mix until a glossy dough forms; it should pull away from the sides easily.

Step 04

Scoop tablespoon‑sized balls onto the prepared sheet, then press each lightly with the tines of a fork to create the classic criss‑cross pattern.

Step 05

Bake for 8‑10 minutes, until the edges are just set and the tops have a faint golden hue.

Step 06

Allow the cookies to cool on the sheet for 2 minutes, then transfer to a wire rack. They’ll firm up as they cool, staying soft inside.

Notes & Tips

  • 1 If the dough feels too sticky, chill for 5 minutes before scooping.
  • 2 A pinch of sea salt on top enhances the peanut flavor.
  • 3 For extra chewiness, substitute half the erythritol with a small amount of allulose.
