Sour-Cream Chocolate Chip Coffee Cake

Anyone have the recipe handy? I can't find mine and am having a coffee/playdate tomorrow morning.

Update: Eileen shared the recipe with me, so I am adding here on the front page so it is nice and easy to find. A family favorite!

Chocolate Chip coffee cake
!/2 cup butter
1 cup sugar
2 eggs 
1 cup sour cream
1 tsp Vanilia
2 cups flour
1 1/2 tsp baking powder
1 tsp baking soda

Topping
1/2 cup sugar
1 cup chocolate chips
1/2 cup chopped nuts
2 tsp cinnamon

Cream together butter,sugar,eggs, sour cream and vanilla. Sift together flour, baking powder, and baking soda. Combine 2 mixes. 
Spoon 1/2 batter into pan. Top with 1/2 chip mixture. Cover with rest of batter. Top with rest of chip mixture.
Bake at 350 for 30 minutes.
Mom always does her in a fluted pan but I have trouble getting it to cook through in that pan so I do a 9x13. So you may need to adjust baking time.
