01 - Preheat the oven to 350°F. Grease and flour a 9x5-inch loaf pan or line with parchment paper.
02 - Combine instant coffee granules or espresso powder with hot water and stir until dissolved; set aside to cool slightly.
03 - In a large bowl, whisk together mashed bananas, melted butter, heavy cream, eggs, granulated sugar, vanilla extract, and the dissolved coffee until the mixture is smooth.
04 - In a separate bowl, whisk together all-purpose flour, baking soda, and salt.
05 - Add the dry ingredients to the bowl containing the wet mixture and stir until just combined, ensuring not to overmix.
06 - Gently fold in the walnuts, pecans, or chocolate chips if using.
07 - Transfer the batter to the prepared loaf pan, smoothing the top evenly. Bake for 50–55 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
08 - Allow the bread to cool in the pan for 10 minutes, then place on a wire rack to cool completely before slicing.
