Dark Chocolate Walnut Brownies 

Pin this recipe

Rich, fudgy, and deeply chocolatey, these brownies get a grown-up twist from a swirl of our Dark Chocolate Balsamic Vinegar — a subtle tang that makes the chocolate taste even more chocolatey.

Ingredients

  • ½ cup roasted walnut oil
  • 1 cup dark chocolate chips
  • ¾ cup granulated sugar
  • ¼ cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 tbsp dark chocolate balsamic vinegar
  • ½ cup all-purpose flour
  • ¼ cup unsweetened cocoa powder
  • ½ tsp baking powder
  • ¼ tsp salt
  • ½ cup chopped walnuts (optional)

Instructions

  1. Preheat oven to 350°F and line an 8×8-inch baking pan with parchment paper.
  2. In a microwave-safe bowl (or using a double boiler), melt chocolate with roasted the walnut oil until smooth letting cool slightly.
  3. Whisk in both sugars. Once combined, add eggs, vanilla extract, and dark chocolate balsamic vinegar, mixing until well combined.
  4. In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
  5. Gradually fold the dry ingredients into the wet mixture until just combined. Stir in chopped walnuts, if using.
  6. Pour batter into the prepared baking pan and smooth the top.
  7. Bake for 25–30 minutes. Let cool before slicing.
