Chocolate Chip Cake

I'm amazed that I never posted this recipe since I make it so often! It's one my family's favorite.

¼ lb butter, softened
1 cup sugar
2 eggs
1 cup sour cream
2 cup flour
1 Tbsp vanilla
1 ½ Tbsp baking powder
1 tsp baking soda
1 – 1 ½ cup chocolate chips

Sugar/Cinnamon Mixture:
½ cup sugar
1 tsp cinnamon

Preheat oven to 350 degrees. Grease and flour a 9x13 pan.

Cream together the first three ingredients. Add the remaining ingredients. Pour half the cake batter into the prepared pan.

Make the sugar and cinnamon mixture in a small bowl. Sprinkle half the sugar/cinnamon mixture and chocolate chips over the cake batter.

Pour the remaining batter over the mixture and cover with remaining sugar/cinnamon and chocolate chips. Bake for 25 to 30 minutes or until a toothpick inserted into the cake comes out clean.
