Ingredients
Scale
For the Cake
- 2 cups all-purpose flour (fluffed and spooned)
- 2 large eggs
- 1 large banana (if small, use 2) peeled and mashed
- 3/4 cup granulated sugar
- 1/2 cup neutral oil (vegetable or canola)
- 1/2 cup chopped walnuts
- 3 tbsp sour cream (or substitute Greek yogurt or buttermilk)
- 2 tsp instant coffee
- 2 tbsp hot water
- 1 tsp baking soda
- 1 tsp vanilla extract
- 1/2 tsp salt
For the Coffee Glaze
- 1 cup powdered sugar
- 1 tsp instant coffee
- 3 tbsp hot water
Instructions
Step 1: Preheat and Prepare the Pan
- Preheat oven to 350°F (175°C).
- Line a standard loaf pan with parchment paper and grease the sides.
Step 2: Mix the Wet Ingredients
- In a bowl, whisk together sugar and eggs for 30 seconds until fluffy.
- Add oil, sour cream, vanilla extract, and hot coffee. Whisk to combine.
- Stir in the mashed banana.
Step 3: Mix the Dry Ingredients
- In a separate bowl, whisk together flour, baking soda, and salt.
- Fold in the chopped walnuts.
Step 4: Combine and Bake
- Gradually mix the dry ingredients into the wet ingredients until fully combined.
- Pour the batter into the prepared loaf pan.
- Bake for 57-60 minutes, or until a toothpick inserted in the center comes out clean.
Step 5: Make the Coffee Glaze
- While the loaf bakes, whisk together hot water, instant coffee, and powdered sugar.
- Once the cake is done, place it on a cooling rack with parchment paper underneath.
- Drizzle the glaze over the warm loaf and let it cool completely before slicing.
Notes
- Flour Measurement Tip: To avoid a dry cake, fluff the flour with a fork, spoon it into the measuring cup, and level it off. Do not scoop directly into the flour bag.
- Glaze Thickness: If too thin, add more powdered sugar. For a thinner glaze, add a splash of hot water or coffee.
- Substitutions: Greek yogurt, buttermilk, or crème fraîche can replace sour cream.
- Chocolate Chip Variation: Swap half of the walnuts with chocolate chips for a sweeter twist.
