Batter:

1 1/2 c. flour
1 tbsp. plus 2 tsp. baking powder
1 1/4 tsp. salt (if you wish)
1/2 c. shortening
1 1/2 c. milk
2 eggs (or egg substitute)

Filling:

1/2 c. dark brown sugar
1/2 c. chopped nuts
2 tsp. cinnamon

Streusel Topping:

1/2 c. flour
1 c. sugar
1/4 c. firm butter

Glaze:

2 c. confectioners' sugar
1/4 c. softened butter
1 tsp. vanilla
1/4 to 1/2 c. water

Mix 1 1/2 cups flour, baking powder, salt, shortening, milk and eggs until moistened. Beat vigorously for 1/2 minute. Butter 2 (9-inch) round or square pans. Spread 1 1/2 cups batter in each pan.

Mix brown sugar, chopped nuts and cinnamon together and sprinkle half over the batter in each pan. Divide remaining batter evenly and spread gently over the filling in each pan. (Do not worry if it does not cover filling entirely.)

To make streusel topping, combine flour, sugar and butter and mix until crumbly. Sprinkle half on top of each pan. Bake at 375°F for 30 to 35 minutes.

Make sugar glaze by mixing confectioners' sugar, softened butter, vanilla and water, adding 2 tablespoons at a time until glaze if of spreading consistency. Drizzle glaze on slightly cooled cakes.
