Ingredients

Scale

Main Ingredients

  • 1 cup creamy peanut butter (240g)
  • ¾ cup packed brown sugar (150g)
  • ½ cup granulated sugar (100g)
  • 2 large eggs, room temperature
  • 2 tsp vanilla extract
  • ⅔ cup all-purpose flour (80g)
  • ¼ cup unsweetened cocoa powder (25g)
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup semi-sweet chocolate chips (175g)
  • ½ cup chopped peanuts (optional)
  • Flaky sea salt (optional, for sprinkling)
  • Extra chocolate chips (for topping)
  • Peanut butter chips (optional)

Instructions

  1. Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone baking mats to prevent sticking and create an even baking surface.
  2. Mix Wet Ingredients: In a large bowl, whisk together the creamy peanut butter, brown sugar, and granulated sugar until they are fully combined and smooth. This base is the key for a rich flavor and chewy texture.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time to ensure thorough mixing and add the vanilla extract. Whisk until the mixture is smooth and glossy, which helps create a uniform dough.
  4. Combine Dry Ingredients: In a separate medium bowl, sift or whisk together all-purpose flour, unsweetened cocoa powder, baking soda, and salt. This ensures even distribution of the leavening and flavoring agents.
  5. Mix Dry and Wet Mixtures: Gently stir the dry ingredients into the wet mixture just until combined. Avoid overmixing to maintain tender texture in the cookies.
  6. Add Chocolate and Peanuts: Fold in the semi-sweet chocolate chips and optional chopped peanuts to add chunks of melting chocolate and crunch for a delightful bite.
  7. Portion Dough: Using a cookie scoop, drop the dough onto the prepared baking sheets, spacing each mound about 2 inches apart to allow for spreading during baking.
  8. Top Cookies: Garnish each dough ball with extra chocolate chips and sprinkle flaky sea salt if desired to add an attractive finish and flavor contrast.
  9. Bake Cookies: Bake for 10–12 minutes, rotating the baking sheets halfway through the baking time. The cookies are done when edges are set and centers remain slightly soft.
  10. Cool Cookies: Allow the cookies to cool on the baking sheets for 5 minutes to set, then transfer them to a wire rack to cool completely ensuring the perfect chewy texture.

Notes

  • Chill the dough if your kitchen is warm to prevent the cookies from spreading too much during baking.
  • Use creamy processed peanut butter rather than natural peanut butter for best texture and consistency.
  • These cookies freeze well both before and after baking, making them convenient for make-ahead treats or gifts.
  • If you’d like to make the recipe egg-free, substitute with flax eggs, but expect texture changes as eggs contribute to the chewy fudgy consistency.
  • Ensure your oven is fully preheated to avoid excessive spreading and achieve perfect cookie texture.
