Note: This is NOT banana bread! This is nothing like your classic banana bread recipe. This is a beer bread, with some bananas in it!
Preheat the oven to 375 degrees F. Spray a 9×5 loaf pan with nonstick spray.
Over a large bowl, sift together the all-purpose, baking powder, cinnamon and the salt. Stir in the mashed bananas. Pour in the beer and stir until a batter forms. It will be thick. Spoon the batter in the greased loaf pan. Pour the melted butter over top. Bake for 50 to 55 minutes, or until the bread is golden brown and set in the middle. Remove the pan from the oven and let cool for about 30 minutes.
Drizzle with the brown butter vanilla glaze and slice.

Add the butter to a small saucepan over medium heat. Whisk constantly until the butter begins to bubble and as soon as brown bits start to appear in the bottom of the pan, remove it from the heat. This will take about 5 minutes. Add the brown butter to a bowl and whisk in the sugar and vanilla extract. If the mixture is too thick to drizzle, whisk in the milk if needed. Pour over the cake once it has cooled and serve!
