2 cups unbleached all-purpose flour
1 cup granulated sugar
2 tablespoons granulated sugar
1 teaspoon table salt
10 tablespoons unsalted butter, softened (1 1/4 sticks)
1 teaspoon baking powder
1/2 teaspoon baking soda
3/4 cup buttermilk

2 teaspoons vanilla extract
3/4 cup walnuts, finely chopped (or pecans)
1/2 cup brown sugar
1 teaspoon ground cinnamon
1/2 teaspoon allspice

Adjust oven rack to center position and heat oven to 350\u00b0.
Generously grease bottom and lightly grease sides of 10-inch springform pan and dust with flour.
With electric mixer, mix flour, sugar, and salt in large mixing bowl until blended.
Cut in butter until mixture resembles coarse crumbs.
Remove 1 cup of crumbs to separate bowl.
Mix baking powder and soda into mixture remaining in large mixing bowl.
Add buttermilk, egg, and vanilla; mix well until batter is thick, smooth, fluffy, and frostinglike, 1 1/2- 2 minutes.
Using a rubber spatula, scrape batter into prepared pan and smooth top.
Add nuts, brown sugar, cinnamon and allspice to reserved crumbs; toss with a fork or your hands until blended.
Sprinkle crumbs over batter, pressing lightly so that mixture adheres.
Bake cake until center is firm and cake tester comes out clean, 50- 55 minutes. TIP: Do not insert a toothpick to test for doneness until center is firm when pan is shaken.
Transfer cake to rack; remove pan sides.
Let cake cool completely, about 2 hours, before serving.
When completely cooled, cake can be slid off pan bottom onto serving plate.
