Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a bowl, mix mashed bananas, melted vegan butter, maple syrup, almond milk, and vanilla extract.
Add baking powder, baking soda, cinnamon, salt, flour, and oats. Stir until combined.
Pour half the batter into the loaf pan.
Mix melted vegan butter, brown sugar, and cinnamon for the swirl. Spread half over the batter.
Add the remaining batter and top with the rest of the cinnamon swirl mixture.
Bake for 50-60 minutes or until a toothpick comes out clean.
Cool the bread before frosting.
For the frosting, mix powdered sugar, melted vegan butter, and softened cream cheese. Spread over the cooled bread.
Serve and enjoy.
