Peanut Butter Chocolate Chunk Cookies

Chock a block full of creamy peanut butter and milk chocolate chunks these thick and chewy Peanut Butter Chocolate Chunk Cookies will be your new favorite cookie!

  • Total Time: 19 minutes
  • Yield: 2 Dozen Cookies 1x


Units Scale
  • 188 grams (1 1/2 Cups) All-Purpose Flour/ Plain Flour
  • 3/4 Teaspoon Baking Soda
  • 3/4 Teaspoon Salt
  • 2 Teaspoons Cornstarch/ Cornflour
  • 4oz (1/2 cup) Butter, softened to room temp.
  • 150 grams (3/4 Cup) Light Brown Sugar
  • 50 grams (1/4 Cup) Granulated Sugar
  • 1 Large Egg, at room temperature
  • 1 Tablespoon Pure Vanilla Extract
  • 4oz (1/2 Cup) Creamy Peanut Butter
  • 60z Chocolate Chips/Chunks


  1. In a medium bowl mix together flour, baking soda, salt, and cornstarch set aside.
  2. In the bowl of an electric mixer cream butter and peanut butter together for 2 minutes, until fully combined and light and fluffy. Add the brown and granulated sugar then mix for 3 minutes. Add in egg and vanilla, mix for another 2 minutes. Gently fold in the flour mixture and then the chocolate chunks. Using a medium cookie scoop, scoop  1.5 Tablespoons size balls of dough. Press extra chocolate pieces on top, if desired. Place dough balls on a parchment lined plate wrapped in plastic wrap or container and chill dough for 1 hour- 48 hours.
  3. When ready to bake preheat the oven to 350F/180C and line a baking sheet with a silpat liner, if using one.
  4. Bake for 8-10 minutes. I like to take cookies out when they look almost done and let sit in pan for 5 minutes then transfer to wire rack to cool completely. Store in an air-tight container for up to 5 days.
