Dark Chocolate Rhubarb Brownies are ultra-fudgy, rich, and perfectly balanced with deep cocoa flavor and bright bursts of tart rhubarb. This seasonal twist on classic brownies delivers intense chocolate depth with refreshing contrast.

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)
  • 1/2 teaspoon espresso powder (optional)
  • Flaky sea salt (optional, for topping)

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, salt, and espresso powder if using.
  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 and sprinkle with flaky sea salt if desired.
  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 for clean cuts.

Notes

  • Use high-quality dark chocolate for best flavor and texture.
  • Dice rhubarb finely to prevent excess moisture pockets.
  • Do not overbake; brownies should have moist crumbs when tested.
  • Cool completely before cutting for neat slices.
  • Store in an airtight container at room temperature for up to 3 days or freeze for up to 3 months.
