Ingredients

Scale
  • 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
  • â…› teaspoon vanilla extract
  • Pinch of salt

Instructions

1. Blend the blueberries until completely smooth to create a puree.

2. Pour the blueberry puree into a saucepan over medium-low heat. Gently simmer, stirring constantly, until reduced to about ½ cup. Remove from heat and allow to cool completely.

3. Preheat oven to 325°F (163°C). Line an 8×8-inch glass baking dish with parchment paper.

4. In a medium bowl, combine melted butter and granulated sugar. Stir in eggs, vanilla extract, and sea salt until smooth and uniform in color.

5. Fold the cooled blueberry reduction into the wet mixture until fully incorporated.

6. Gradually add the sifted flour, stirring just until combined. Do not overmix.

7. Pour the batter into the prepared baking dish and spread evenly.

8. Bake on the middle rack for 35–40 minutes, checking at 30 minutes. The center should be set and a toothpick inserted should come out clean or with a few moist crumbs.

9. Allow brownies to cool completely in the pan.

10. Whisk together powdered sugar, milk, vanilla extract, and a pinch of salt until smooth and silky.

11. Spread half of the glaze evenly over the cooled brownies. Once set, spread the remaining glaze on top and allow to fully harden.

12. Cut into 16 squares and store leftovers in an airtight container.

Notes

Do not skip reducing the blueberry puree, as this intensifies flavor and prevents excess moisture.

Frozen blueberries must be fully thawed and drained before blending.

For clean cuts, chill the brownies slightly before slicing.

Store at room temperature for up to 3 days or refrigerate for longer freshness.
