Sunday Brunch - Coffee Cake

I made this last weekend while company was here and it disappeared pretty quick.

INGREDIENTS:
1/2 Cup Brown Sugar
1/4 Cup All-Purpose Flour
1/4 Cup Margarine
1 tsp Cinnamon

1 1/2 Cup Flour
2 1/2 tsp Baking Powder
1/2 tsp Salt
1 Egg Replacer
3/4 cup Sugar
1/3 cup Melted Margarine
1/2 Cup Soy Milk
1 tsp Vanilla

Stir together brown sugar, a/4 cup flour and cinnamon in a medium bowl; knife in 1/4 cup margarine until crumbly.

Mix flour, salt and baking powder together. In a separate bowl, cream the sugar, melted margarine and egg replacer, then add soy milk and vanilla. Add flour mixture to wet mix and combine. Pour cake mix in a 9" square pan, greased. Crumble brown sugar mixture evenly over the top and bake at 375F for 25 minutes, or until the a fork comes out clean.
