Ingredients

Scale
  • 6 ounces dark chocolate (60–70% cocoa), chopped
  • 1/2 cup unsalted butter
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 cup fresh rhubarb, finely diced
  • 1 tablespoon flour (optional, for tossing rhubarb)

Instructions

  1. Preheat oven to 350°F and line an 8×8-inch baking pan with parchment paper.
  2. Melt chopped dark chocolate and butter together using a double boiler or microwave in short intervals, stirring until smooth. Let cool slightly.
  3. In a bowl, whisk sugar and eggs until slightly thickened. Stir in vanilla extract.
  4. Gradually pour the cooled chocolate mixture into the egg mixture, stirring continuously.
  5. In a separate bowl, whisk together flour, cocoa powder, and salt.
  6. Fold dry ingredients into the wet mixture until just combined. Do not overmix.
  7. If needed, toss diced rhubarb with 1 tablespoon flour, then gently fold into the batter.
  8. Spread batter evenly into prepared pan.
  9. Bake for 25–30 minutes, until edges are set and a toothpick inserted in the center comes out with moist crumbs.
  10. Allow brownies to cool completely before slicing and serving.

Notes

  • Use high-quality dark chocolate for best flavor.
  • Dice rhubarb finely to prevent excess moisture pockets.
  • Do not overbake to maintain a fudgy texture.
  • Store in an airtight container at room temperature for up to 3 days.
  • Brownies can be frozen individually for up to 3 months.
