Aunt Martha's Jewish Coffee Cake Recipe

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.
