Chocolate Chip Coffee Cake

1 cup butter
1 cup sugar
2 eggs
1 cup sour cream
1 tsp. baking soda
1 tsp. salt
1 tsp. baking powder
2 tsp. vanilla
2 cups flour

In a large bowl, cream butter and sugar until smooth. Add remaining ingredients, except flour. Gradually stir in flour and mix well. Preheat the oven to 350 degrees.

Topping
1/4 cup sugar
1/3 cup brown sugar
1 tsp. cinnamon
1 cup chopped pecans or walnuts
1 cup chocolate chips (I use milk c.c. but you can use semi-sweet if you prefer)

Mix topping ingredients together. Sprinkle a greased bunt pan with 1/3 of the topping. Alternate layers of topping and batter, ending with topping. Bake for 45-60 minutes.

FYI-
I usually make a little extra of the topping mixture and mine always takes 60 minutes, sometimes a little longer.
