Instructions
Preheat oven to 425°F and fill a jumbo muffin pan with parchment liners.
In a large bowl, mix together the melted butter and brown sugar. Stir in the vanilla extract, egg, sour cream, and mashed bananas really well.
In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt, Fold them into the wet ingredients just until the flour streaks disappear.
Equally distribute the batter into the muffin liners and bake on the middle rack at 425°F for 6 minutes. Then, without opening the oven door, reduce the temperature to 375°F and bake until a toothpick comes out of the center clean (about 16-20 more minutes; 22-26 minutes total).
Let the muffins sit in the pan for 10 minutes, then transfer to a wire rack to finish cooling.
When the muffins have cooled completely and are ready to be served, brush the tops with melted butter and dip them in the cinnamon sugar topping.
Notes
Butter: These muffins are extra rich and buttery so that it's like eating a slice of banana bread lathered in butter! If you want them to be less rich, try using only 6 tablespoons of butter (however, they may not be quite as moist and fluffy this way).Regular Muffins: Distribute the batter between 12-14 regular muffin liners and bake at 375°F for about 15-20 minutes.Mini Muffins: Bake 24-28 mini muffins at 350°F for 10-15 minutes.Storage: Store cooled, uncoated banana bread muffins in an airtight container at room temperature for 1 week or in the freezer for 3 months. Top with butter and cinnamon sugar when ready to serve.Nutrition: The provided nutrition information is an estimate, the calorie accuracy is not guaranteed.
