These Blackberry Cookies are soft, buttery, and naturally tinted a beautiful blue-purple hue from fresh blackberries. Bursting with fruity flavor and tender in texture, they make a stunning and delicious addition to any cookie tray—without artificial dyes.

Ingredients

  • 1 cup fresh blackberries
  • 1/2 cup granulated sugar
  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar, packed
  • 1 large egg
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • Optional: 1/2 cup white chocolate chips or chopped nuts

Instructions

  1. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. Mash blackberries in a small bowl until juicy and slightly broken down.
  3. In a large bowl, cream butter, granulated sugar, and brown sugar until light and fluffy.
  4. Beat in egg and vanilla extract, then stir in mashed blackberries. Dough will turn a vibrant purple-blue.
  5. In another bowl, whisk together flour, baking powder, baking soda, and salt.
  6. Add dry ingredients to wet mixture, stirring until just combined. Fold in optional white chocolate chips or nuts.
  7. Scoop dough onto prepared baking sheet, spacing cookies about 2 inches apart.
  8. Bake for 10–12 minutes, until edges are set but centers remain soft.
  9. Cool on baking sheet for a few minutes before transferring to a wire rack.

Notes

  • Frozen blackberries can be used—thaw and drain before mashing.
  • Add a squeeze of lemon juice for a tangier flavor.
  • Roll dough balls in coarse sugar before baking for a sparkly finish.
  • Store at room temperature for up to 3 days, in fridge for up to a week, or freeze for up to 2 months.
  • Microwave for 8 seconds to restore fresh-baked softness.
