3 very ripe bananas
1 large egg at room temp
2 tablespoons sour cream or yogurt
2 ounces of espresso
1 teaspoon vanilla extract
1 teaspoon ground espresso
1/3 cup unsalted butter, melted
¾ cups granulated sugar
1 ½ cups flour
1 teaspoon baking soda
1 teaspoon kosher salt
Preheat oven to 350°F and grease a 9X5-inch loaf pan.
In a medium-large mixing bowl, stir the mashed bananas together with the egg, sour cream, espresso, and vanilla extract, until everything is well combined.
Stir in the instant espresso.
Stir in the melted butter until it is completely incorporated. Follow this by stirring in the sugar until everything is well mixed.
In a small bowl, stir together the flour, baking soda, and salt.
Dump this mixture into the wet ingredients and stir just until there are no dry streaks left. The batter will still be lumpy. Scrape the batter into the prepared loaf pan and bake in the oven until a tester inserted into the loaf comes out clean, about one hour.
Remove from the oven, allow to cool.
