These glazed blueberry brownies are a twist on classic blondies that I come back to every summer when blueberries are at their peak. Each bite is extra chewy thanks to real blueberry puree not just flavoring and a tangy sweet glaze that soaks right in. They are perfect when you crave something playful and fruity but still deeply indulgent.
Ingredients
- Fresh or frozen blueberries: choose plump unbruised berries for the boldest taste and color
- Unsalted butter: melted for an ultra moist finish and balanced creamy base
- Granulated sugar: creates a perfectly sweet dough that balances the tartness
- Eggs: at room temperature make the brownies extra tender and hold everything together smoothly
- Vanilla extract: rounds out the berry flavor use pure vanilla for best results
- Sea salt: brings out all the flavors and ensures a pleasant not too sweet bite
- All purpose flour: sifted for a smooth even crumb with just the right structure
- Powdered sugar: for the glaze gives a luxuriously smooth topping
- Milk: thins the glaze making it easy to pour and set with a glossy finish
- A pinch of salt in the glaze: keeps it from tasting cloying and highlights the berry notes

- Bake:
- Pour the thick batter into your lined baking dish spreading out to the edges with a spatula for an even bake set on the center rack and bake for thirty five to forty minutes or until the center is just set and a toothpick comes out with a few moist crumbs do not overbake
- Prepare and Glaze:

Blueberries are my absolute favorite to bake with since childhood when I picked buckets full every June the scent as they simmer down is pure nostalgia and the color always makes my kids smile at the first slice

A Bit of History
Brownies are usually all about the chocolate but fruit based blondies have a long history in American baking where resourceful home cooks would use whatever berries and fruit were on hand in peak season Try this recipe as an ode to Southern summer blueberry festivals or swap different berries when in season
