Step 1

Preheat the oven to 350ºF/180°C.

Step 2

Butter or spray a 9x5 inch loaf pan. Line the pan with a strip of parchment paper, covering the bottom and two short sides. The two long sides will remain unlined but greased. This will help you remove the bread from the pan after it’s baked.

Step 3

In a large bowl beat ½ cup unsalted butter with 1 cup sugar until light and fluffy.

Step 4

Add 2 eggs and beat for a minute.

Step 5

Add 1 teaspoon vanilla extract and mix.

Step 6

In another bowl sift together 2 cups all-purpose flour, ¼ teaspoon salt and 1 teaspoon baking soda.

Step 7

Add dry ingredients in three additions alternating with 1 cup sour cream in two additions. Mix only until combined. Don't overmix it at this point as it will make the bread tough.

Step 8

Add 1 cup walnuts. Mix well and pour into the prepared pan.

Step 9

Bake for 50 to 60 minutes, until golden, cracked, and a cake tester or toothpick inserted in the center comes out clean. Let cool on a wire rack, remove from the pan and glaze.

Step 10

Mix 1 cup powdered sugar and 1 tablespoon drip coffee in a small bowl until smooth.

Step 11

Drizzle over the cool bread, letting it drip down the sides. Sprinkle with ¼ cup walnuts, chopped, before it dries.
