Set your oven to 375°F (190°C). Grease a 9x13-inch dish and give it a quick coating of flour after.
02 -
Mix the sugar with butter in a big bowl until it’s nice and fluffy.
03 -
Crack in one egg, stir, then add the next. Pour in the sour cream and vanilla, then give it all a good mix.
04 -
Take another bowl and whisk together the flour, salt, and soda. Slowly mix these dry ingredients into the wet ones until just blended.
05 -
Stir the mashed bananas into the batter gently.
06 -
Pour the batter into the greased dish and bake for 20-25 minutes. Check with a toothpick—it should come out clean when it's done.
07 -
Put the dish on a rack and leave it alone until completely cooled.
08 -
Melt butter in a pan over medium. Let it get a bit golden, then pull it off the heat so it doesn't overcook.
09 -
In a bowl, blend the golden butter, powdered sugar, vanilla, and milk until it's creamy.

Once cool, spread the frosting on top, cut into squares, and enjoy.
