A thick slice of banana bread with butter melting into every crack. High calorie comfort snacking that makes the whole house smell incredible.
Preheat oven to 350°F. Grease a 9x5-inch loaf pan to prevent sticking and set aside.
Mash the ripe bananas in a large mixing bowl until smooth, then mix in the brown sugar and melted butter while still warm to help dissolve the sugar.
Beat in the eggs one at a time, mixing until fully incorporated. Stir in the milk and vanilla extract for an even batter.
In a separate bowl, whisk together the flour, baking powder, salt, and cinnamon. Gradually fold dry ingredients into the wet mixture; avoid overmixing for tender crumb.
Pour the batter into the prepared loaf pan. Bake for 55–60 minutes, checking with a toothpick at 50 minutes. Allow to cool for 15 minutes, then slice thickly and serve with additional butter spread on top.
