Step 1

Preheat oven to 350 degrees F and grease a 9x5 baking dish.

Step 2

In a medium-sized bowl, whisk the flour, baking soda, cinnamon, and salt together. Set aside.

Step 3

In a large bowl, beat the brown sugar and butter until creamy and then add the eggs one at a time.

Step 4

Add the sour cream, mashed bananas, and vanilla to the sugar mixture and beat until combined.

Step 5

Slowly add the dry ingredients to the wet ingredients until just combined. Do not overmix.

Step 6

Transfer batter to the prepared loaf pan and bake for 55-60 minutes or until an inserted toothpick comes out clean. While bread is cooling, make the glaze.

Step 7

In a small saucepan, combine the brown sugar and butter and bring to a boil over medium heat. Continue cooking until the sugar has fully dissolved, approximately 1 minute.

Step 8

Stir in heavy cream and remove the pan from the heat. Add in the powdered sugar and salt, mix until smooth.

Step 9

Allow glaze to cool for 5 minutes before pouring it over the bread.
