Ingredients
  

  • 2 cups all-purpose flour
  • ½ teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • ¾ cup unsalted butter, softened
  • 1 ¼ cups light brown sugar, packed
  • 1 large egg
  • 2 teaspoons pure vanilla extract
  • 1 ¼ cups fresh rhubarb, diced about ½-inch pieces
  • 2 tablespoons granulated sugar for sprinkling

Instructions
 

  • Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
  • In a medium bowl, whisk together flour, baking soda, baking powder, and salt.
  • In a large bowl, beat the softened butter and brown sugar together until light and fluffy, about 2-3 minutes.
  • Add the egg and vanilla extract to the butter mixture and beat until combined.
  • Gradually mix in the dry ingredients until just combined.
  • Gently fold in the diced rhubarb.
  • Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing about 2 inches apart.
  • Lightly sprinkle each cookie with a little granulated sugar before baking.
  • Bake for 10-12 minutes, or until the edges are golden and the centers are set.
  • Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

Make sure your rhubarb is dry after washing to prevent extra moisture in the dough. These cookies can be frozen for up to 2 months. For a twist, add a pinch of cinnamon or ginger to the dough!
