Ingredients

Scale

Brownie Batter

  • 1½ cups blueberries, fresh or frozen (thawed)
  • 10 tablespoons unsalted butter, melted
  • 1¼ cups granulated sugar
  • 2 large eggs, room temperature
  • ½ teaspoon vanilla extract
  • ½ teaspoon sea salt
  • 1 cup all-purpose flour, sifted

Glaze

  • 1 cup powdered sugar, sifted
  • 2 tablespoons milk
  • ⅛ teaspoon vanilla extract
  • pinch of salt

Instructions

  1. Prepare Blueberry Puree: Blend the blueberries in a blender or food processor until completely smooth to form a puree.
  2. Cook the Puree: Pour the blueberry puree into a saucepan and place it over medium-low heat. Simmer gently, stirring constantly, until the liquid reduces to about ½ cup. Remove from heat and let it cool completely before using.
  3. Prep the Baking Dish: Preheat your oven to 325°F (163°C). Line an 8×8 inch glass baking dish with parchment paper, ensuring some overhang for easy removal of the brownies.
  4. Mix Wet Ingredients: In a medium mixing bowl, combine the melted butter and granulated sugar. Stir well, then incorporate the eggs, vanilla extract, and sea salt, mixing until the batter is smooth and uniform in color. Fold in the cooled blueberry reduction gently.
  5. Combine Dry Ingredients: Gradually add the sifted all-purpose flour to the wet mixture, folding or stirring gently just until combined to avoid overmixing.
  6. Bake: Pour the brownie batter evenly into the prepared baking dish. Bake on the middle rack of the oven for 35 to 40 minutes. Begin checking at 30 minutes by inserting a toothpick into the center—it should come out clean or with a few moist crumbs attached when done.
  7. Make & Apply Glaze: While the brownies cool completely, prepare the glaze by whisking together the powdered sugar, milk, vanilla extract, and a pinch of salt until smooth and silky. Spread half of the glaze evenly over the cooled brownies. Let it harden before applying the remaining glaze on top. Allow the final layer to harden fully before serving.
  8. Cut and Store: Once the glaze is set, cut the brownies into 16 equal squares. Store any leftovers in an airtight container at room temperature to keep them fresh.

Notes

  • Using fresh blueberries will give the brightest flavor, but thawed frozen blueberries work well too.
  • Be careful not to overbake the brownies to maintain moistness; check early and often starting at 30 minutes.
  • The glaze adds a nice sweet finish—ensure the brownies are fully cooled before glazing to prevent melting.
  • You can substitute milk with any milk alternative if preferred.
  • Parchment paper with overhang makes it easy to lift the entire brownie slab from the pan for clean cutting.
  • These brownies store well for 3-4 days at room temperature and can be frozen for longer storage.
