Instructions

Preheat oven to 350. Butter and flour a 10" tube pan, a 9" springform pan or an 8" square pan. To make the streusel, in a medium bowl, combine the graham cracker crumbs, walnuts, brown sugar, cinnamon, cardamom and melted butter.
Blend well and set aside. To make the cake, sift the flour, sugar, baking powder and salt into a large bowl. Add the butter, eggs, vanilla and milk.
Beat vigorously until smooth and quite thick, about 1 minute. Spread
half of the batter into prepared pan and sprinkle with half the streusel mixture.
Spoon remaining batter over the streusel and top with remaining streusel.
Bake until cake tests done, about 50 minutes. Cool about 20 minutes, then remove cake from pan. Serves 10-12
