Aunt Martha'S Jewish Coffee Cake - cooking recipe

Ingredients

3 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
1 pinch salt
1 cup butter
1 1/2 cups white sugar
3 eggs
1 teaspoon vanilla extract
1 cup sour cream
1 cup chopped walnuts (optional)
3/4 cup white sugar (optional)
1 tablespoon ground cinnamon (optional)
1 pinch ground nutmeg (optional)

Preparation

Preheat an oven to 350 degrees F (175 degrees C). Grease a 9x5-inch loaf pan. Combine flour, baking powder, baking soda, and salt in a bowl.
Beat the butter and 1 1/2 cups of sugar with an electric mixer in a large bowl until light and fluffy. The mixture should be noticeably lighter in color. Add the room-temperature eggs one at a time, allowing each egg to blend into the butter mixture before adding the next. Beat in the vanilla with the last egg. Pour in the flour mixture alternately with the sour cream, mixing until just incorporated.
Mix walnuts, 3/4 cup of sugar, cinnamon, and nutmeg in a bowl. Fold half of the walnut mixture into the batter; mixing just enough to evenly combine. Pour the batter into the prepared pan, then sprinkle the remaining walnut mixture on top.
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 45 minutes. Cool in the pan for 10 minutes before removing to cool completely on a wire rack.
