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.

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
