    How to Make Sourdough Peanut Butter Cookies

    1. Brown: Begin by cutting the butter into cubes and placing it in a light-colored pan over medium heat. Stir frequently for about 5 minutes until it turns golden brown and releases a nutty aroma.
    2. Mix: In a large bowl, combine the brown sugar, granulated sugar, brown butter, and creamy peanut butter. Stir until everything melds together beautifully.
    3. Add: Incorporate the egg, sourdough discard, and vanilla extract into the bowl. Mix until the batter is smooth and inviting.
    4. Combine: Gently fold in the baking soda, salt, and flour. Blend just until combined; avoid overmixing for a tender cookie.
    5. Scoop: Using a 2-tablespoon cookie scoop, form dough balls and place them on a baking sheet lined with parchment paper.
    6. Bake: Preheat your oven to 350°F (175°C) and bake the cookies for 11-13 minutes, until the edges are golden and the tops lose their sheen.
    7. Cool: Let the cookies rest on the baking sheet for a few minutes before transferring them to a cooling rack to finish cooling.

    💡 Pro Tip: For an extra flavor boost, you can always add a handful of chocolate chips or chopped nuts to the dough!
