Ingredients: What You’ll Need

Makes about 16–20 cookies

  • 1 cup (240 g) peanut butter
    • Creamy or crunchy, regular (not natural that separates) works best
  • 1 cup (200 g) granulated sugar
  • 1 large egg

Optional Extras (Not Required)

  • 1 tsp vanilla extract
  • Pinch of salt (especially if using unsalted peanut butter)
  • ¼ cup (45 g) mini chocolate chips or chopped chocolate
  • ¼ tsp cinnamon, for a warm twist

Instructions: Step-by-Step Preparation

  1. Prep Oven & Pan
    • Preheat oven to 175°C.
    • Line a baking sheet with parchment paper.
  2. Mix the Dough
    • In a medium bowl, add:
      • Peanut butter
      • Sugar
      • Egg
      • Vanilla and salt, if using
    • Stir with a spoon or spatula until fully combined and thick.
    • If adding chocolate chips, fold them in now.
  3. Shape the Cookies
    • Scoop about 1 Tbsp of dough per cookie and roll into balls.
    • Place them on the prepared baking sheet about 5 cm apart.
    • Using a fork, gently press each ball down in a criss-cross pattern (press one way, then the other) to flatten slightly.
  4. Bake
    • Bake at 175°C for 8–10 minutes, until:
      • Edges are set and lightly golden
      • Centers still look soft (they’ll firm up as they cool)
  5. Cool & Enjoy
    • Let cookies cool on the baking sheet for 5 minutes.
    • Transfer to a wire rack to cool completely.
    • Enjoy warm or at room temperature.

How to Store It

  • Room Temperature:
    • Store cooled cookies in an airtight container for 3–4 days.
  • Freezer:
    • Freeze baked cookies in a freezer bag or container for up to 2 months.
    • Thaw at room temperature or microwave for a few seconds for a soft, warm cookie.

Smart Ingredient Swaps

  • Natural Peanut Butter:
    • You can use it, but:
      • Stir very well to combine the oil and solids
      • You may need 1–2 Tbsp extra sugar to help bind and sweeten
      • Chilling the dough for 15–20 minutes can help if it seems too loose
  • Other Nut & Seed Butters:
    • Almond butter, cashew butter, or sunflower seed butter work; texture and taste will vary slightly.
  • Sugar Variations:
    • Use brown sugar for a deeper, caramel-like flavor and softer texture.
    • Use half white, half brown sugar for the best of both.

How to Serve It

Serve 3-Ingredient Peanut Butter Cookies:

  • With a glass of cold milk
  • Alongside coffee or tea
  • Crumbled over ice cream or yogurt

They’re great for:

  • Bake sales & potlucks
  • After-school snacks
  • Simple dessert platters

Flavor Variations

Keep the 3-ingredient base and just add a twist:

  • Chocolate-Drizzled:
    • Drizzle cooled cookies with melted chocolate.
  • Peanut Butter Blossom Style:
    • Skip the fork marks and press a chocolate kiss into the center right after baking.
  • Salted Peanut Butter Cookies:
    • Sprinkle warm cookies with flaky sea salt right after they come out of the oven.
  • PB&J Cookies (Easiest Version):
    • Make a thumbprint indent after baking and spoon in a tiny bit of jam (once cooled).

Tips for Best Results

  • Don’t overbake—pull them when centers are just set; they’ll firm up as they cool.
  • Use a regular, shelf-stable peanut butter for the most consistent result.
  • If the dough feels very sticky, chill it for 10–15 minutes before rolling.

Frequently Asked Questions

Can I make these cookies without eggs?

  • You can try a flax “egg” (1 Tbsp ground flax + 3 Tbsp water), but the texture will be more crumbly and less chewy.

Why are my cookies crumbly?

  • Common reasons:
    • Overbaking
    • Very dry or natural peanut butter with separated oils
    • You can try adding an extra egg yolk next time for more moisture.

Do I need baking soda or flour?

  • No. The structure comes from the egg + sugar + peanut butter combo. That’s the beauty of this recipe!

Notes
