Mom's Coffee Cake

Batter:
1 cup granulated sugar
1/2 cup margarine
3 eggs
1 tsp vanilla
1 3/4 cup flour
1 tsp baking soda
1 1/2 tsp baking powder
1 cup sour cream or buttermilk (I used light sour cream)

Topping:
3/4 cup brown sugar 
2 tbsp cinnamon

 Beat sugar, eggs, and vanilla until light.  Mix flour, soda, powder into creamed mixture.  Add margarine.  Spread 1/2 batter in greased (I used pam) angel food cake pan, sprinkle 1/2 topping on and then add the remaining batter and finish with topping.  Bake at 350 degrees for 30-35 minutes or until done (to me this means when a toothpick comes clean).

  Mine is good, but I did make a few changes.  I am thinking that my mom used to use buttermilk instead, the sour cream seemed a little thick - but I would like to try it the other way just to compare the difference.  Also my margarine was in the fridge so I microwaved it and added it in melted.  I think having it at room temperature and mixing it in would have been better.  I also used dark brown sugar, my mom always used light brown sugar....I bet that changed the flavor profile as well....at any rate I hope the recipients enjoy this one!  I thought it was fun that when I cut into the cake it looked like it was smiling at me!
