Description

These Chocolate Rhubarb Brownies combine the tartness of fresh rhubarb with rich cocoa and dark chocolate for a decadent yet refreshing twist on classic brownies. Studded with nuts for added crunch, these moist and fudgy brownies are perfect for a unique dessert or snack.


Ingredients

Scale

Wet Ingredients

  • 1 cup granulated sugar
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1/2 cup all-purpose flour (can substitute gluten-free or almond flour)
  • 1/3 cup cocoa powder
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon sea salt

Add-ins

  • 1 cup rhubarb, diced small
  • 1/2 cup dark chocolate chips
  • 1/2 cup chopped walnuts or pecans


Instructions

  1. Prep Oven and Pan: Preheat your oven to 375°F (190°C). Line an 8×8 inch baking pan with parchment paper and lightly butter the top to prevent sticking.
  2. Combine Wet Ingredients: In a medium bowl, whisk together the sugar, vegetable oil, eggs, and vanilla extract until smooth and fully combined.
  3. Mix Dry Ingredients: In a separate large bowl, whisk the flour, cocoa powder, baking powder, and sea salt until evenly blended.
  4. Combine Wet and Dry: Add the wet ingredients to the dry ingredients. Stir just until incorporated, being careful not to overmix. The batter will be quite thick.
  5. Add Rhubarb, Chocolate Chips, and Nuts: Fold in the diced rhubarb, dark chocolate chips, and chopped walnuts or pecans until evenly distributed throughout the batter.
  6. Bake: Pour the batter into the prepared pan and smooth the top. Bake for 20–25 minutes, or until a toothpick inserted into the center comes out mostly clean. If using frozen rhubarb, increase baking time by 10–15 minutes.
  7. Cool and Serve: Remove brownies from the oven and allow to cool in the pan for at least 10 minutes. Cut into 9 squares and serve warm or at room temperature.

Notes

  • You can substitute gluten-free or almond flour in place of all-purpose flour for a gluten-free option.
  • Using fresh rhubarb is preferred, but if using frozen rhubarb, increase baking time by 10-15 minutes.
  • For nut-free brownies, simply omit the nuts or substitute with seeds like pumpkin or sunflower seeds.
  • These brownies are delightful served slightly warm with a scoop of vanilla ice cream.
  • Make sure not to overmix the batter to keep the brownies tender and fudgy.
