  • Yield: 9 squares 1x

Ingredients

Scale
  • 1 cup granulated sugar
  • ½ cup vegetable oil

  • ⅓ cup unsweetened cocoa powder
  • ½ teaspoon baking powder
  • ½ teaspoon sea salt
  • 1 cup rhubarb, diced small
  • ½ cup dark chocolate chips
  • ½ cup chopped walnuts or pecans

Instructions

  1. Preheat oven to 375°F (190°C).

  9. Spread batter evenly into the prepared pan and smooth the top.
  10. Bake for 20–25 minutes at 375°F, or 10–15 minutes longer if using frozen rhubarb, until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  11. Remove from oven and cool for at least 10 minutes before cutting.
  12. Cut into 9 squares.

Notes

Chop rhubarb into small, uniform pieces to avoid sogginess., Thoroughly thaw and dry frozen rhubarb; increase bake time by 10-15 minutes when using frozen., Mix wet and dry ingredients just until combined to maintain tenderness., Line pan with parchment paper and lightly buttering ensures easy removal and clean edges., For thicker brownies, increase ingredients by half and bake about 5 minutes longer., These brownies freeze well; cool completely before wrapping individually for best results., Milk or semi-sweet chocolate chips can substitute dark chocolate chips., Nuts can be omitted for a nut-free version.
