Chewy glazed blueberry brownies are a unique twist on classic brownies with no cocoa or food coloring. They burst with real blueberry flavor and are crowned with a tangy sweet glaze that sets up perfectly. If you love fruity desserts and want something both comforting and vibrant, these are a must-bake.
Every time I bake these, the kitchen fills with the sweet scent of berries. My niece asks for “the purple brownies” at every family get-together.

Step-by-Step Instructions
- Prepare Blueberry Puree:
- Blend all your blueberries until completely smooth This gives your brownies natural color and flavor from whole fruit
- Cook Down the Puree:
- Simmer your blueberry puree in a saucepan over medium-low heat Stir constantly and watch it closely until it thickens and reduces to about half a cup Let this cool off the heat This step concentrates the berry taste
- Prep the Baking Dish:
- Heat your oven to 325 degrees Place parchment in an eight-inch square glass baking dish This helps you lift the brownies out easily
- Mix the Wet Ingredients:
- Stir together melted butter and sugar in a medium bowl until combined Add eggs vanilla and salt Whisk until the mixture is smooth and uniform in color Finally fold in the cooled blueberry reduction to make the batter a pretty purple
- Combine Dry Ingredients:
- Slowly add sifted flour and stir gently until just combined Be careful not to overmix or your brownies can get tough
- Bake the Brownies:
- Pour the batter in and smooth the top with a spatula Place on your oven’s middle rack Bake for thirty-five to forty minutes Start checking around thirty minutes Insert a toothpick in the center and it should come out with just a few moist crumbs
- Mix and Apply the Glaze:
- In a small bowl combine sifted powdered sugar milk vanilla and a pinch of salt Stir until silky and smooth When brownies are completely cool spread on half the glaze Once it hardens spread the rest and let it set for a pretty layered finish
- Cut and Store:
- Cut your brownies into sixteen neat squares Store leftovers in an airtight container to keep them from drying out

I always look forward to swirling the rich purple blueberry reduction into the batter The burst of real blueberry is what makes these so special to me It reminds me of berry picking trips with my grandma every summer
Storage Tips
These brownies keep their best texture for three days stored in an airtight container at room temperature For longer storage freeze individual squares on a tray then wrap tightly and store in a freezer-safe bag for up to two months Let them thaw at room temperature before serving
Ingredient Substitutions
Use wild blueberries for extra flavor if available If you’re out of fresh or frozen berries you can try a high-quality blueberry puree in the same amount Dairy-free milk works in the glaze if you prefer
Serving Suggestions
Serve chilled for a fudgier bite or let them come to room temperature for even more chewiness These are wonderful with a scoop of vanilla ice cream or a dollop of whipped cream For a brunch treat try them alongside coffee or lemon tea
