Preheat the oven to 350°F (175°C) and lightly spray a 6-cup loaf pan with nonstick baking spray.

In a small mixing bowl, combine the all-purpose flour, baking soda, and salt. Whisk thoroughly for about 30 seconds.

In a large mixing bowl, whisk together melted butter and brown sugar until smooth, then add eggs, vanilla extract, and lavender extract.

Fold in the mashed bananas gently until just combined.

Gradually fold the dry ingredients into the wet mixture with a spatula until just incorporated.

Pour the batter into the prepared loaf pan and bake for 55 to 60 minutes.

Remove from the oven and let it cool for about 15 minutes before inverting onto parchment paper.

To make the glaze, whisk together powdered sugar, vanilla extract, lavender extract, and heavy cream; adjust with milk as needed.

Once the bread is cool, drizzle the glaze over the top and sprinkle with culinary lavender flowers.
