Banana Coffee Cake.

Banana Coffee Cake

Patricia Martinescu from Bake Cook Repeat
I know this statement may seem dramatic but this is the best Banana Coffee Cake you will ever have. Rich coffee flavor, moist tender crumb and a luscious coffee glaze for an extra indulgent touch. Think your favorite coffee cake at the café but actually made with coffee and even better!

Ingredients
 
 

  • 2 cups all-purpose flour, fluffed and spooned
  • 2 large eggs
  • 1 large banana, if small use 2 bananas peeled and smashed
  • 3/4 cup granulated sugar
  • 1/2 cup neutral oil vegetable or canola
  • 1/2 cup chopped walnuts
  • 3 Tablespoons sour cream may substitute with Greek yogurt or buttermilk
  • 2 teaspoons instant coffee
  • 2 Tablespoons hot water
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt

For the coffee glaze:

  • 1 cup powdered sugar
  • 1 teaspoon instant coffee
  • 2 Tablespoons hot water

Instructions
 

Preheat and prepare.

  • Preheat the oven to 350°F. Line a standard loaf pan with parchment paper and grease all sides. Set aside.

Combine the wet ingredients.

  • In a medium bowl, whisk together the sugar and eggs for about 30 seconds until fluffy and light yellow. This dissolves the sugar but also incorporates air into the batter. Add the oil, sour cream, vanilla extract and hot coffee. Whisk to combine. Then, mix in the smashed bananas.
    2 large eggs, 3/4 cup granulated sugar, 1/2 cup neutral oil, 3 Tablespoons sour cream, 2 teaspoons instant coffee, 2 Tablespoons hot water, 1 teaspoon vanilla extract, 1 large banana, if small use 2 bananas

Combine the dry ingredients.

  • Whisk in the flour, baking soda and salt until no more flour is visible. Then, fold in the chopped walnuts.
    Note: Measure flour by weight in grams instead of cups. Shop my exact scale here. (affiliate link) If you don't have a scale, fluff the flour with a fork in its bag or container, then spoon it into the measuring cup before leveling off with a flat edge. Do not scoop directly into the flour bag. This will add way too much flour to the batter, making it dry! Toggle back from US Customary to Metric conversion in my ingredients section above to find the weight in grams.
    Note: Chocolate chips are a delicious addition to my Banana Coffee Cake. Substitute half of the walnuts with chocolate chips to prevent the loaf from becoming too dense.
    2 cups all-purpose flour, fluffed and spooned, 1 teaspoon baking soda, 1/2 teaspoon salt, 1/2 cup chopped walnuts

Bake.

  • Bake for 57-60 minutes until a toothpick in inserted to the center and it comes out clean. Do not overbake.
  • While the loaf bakes, combine the hot water and instant coffee. Whisk together with the powdered sugar. It may seem like a lot but most of the icing will drip off. It will thicken as it sets.
    Note: If using drip coffee, substitute my ratios for 1 Tablespoon of hot water and 1 Tablespoon of hot coffee.
    1 cup powdered sugar, 2 Tablespoons hot water, 1 teaspoon instant coffee
  • Place the loaf on a cooling wrack with parchment paper or a pan underneath. Drizzle the icing over the hot loaf and let it cool completely before slicing. The warmth from the loaf will thin out the icing.
    Note: To get the same glazed look in my photos, pour the icing over the loaf while its still warm.

Notes

  • Measure flour by weight in grams instead of cups. Shop my exact scale here. (affiliate link) If you don't have a scale, fluff the flour with a fork in its container, and then spoon it into the measuring cup before leveling off with a flat edge. Do not scoop directly into the flour bag. This will add way too much flour to the batter, making it dry!
  • If your glaze is too thin, add more powdered sugar. For a thinner glaze, add an additional splash of coffee or hot water.
  • Greek yogurt, buttermilk or crème fraiche work well as a substitute for sour cream.
  • Chocolate chips are a delicious addition to my Banana Coffee Cake. Substitute half of the walnuts with chocolate chips to prevent the loaf from becoming too dense.
