Chocolate Chip SourCream Cinnamon Coffee Cake

Cream:

• 1/2 cup butter, softened
• 1 cup Sugar
• 2 eggs
• 1 cup sour cream
• 1 teaspoon vanilla extract
• 
  

Premixed Dry Ingredients:

• 2 1/2 cups all-purpose flour
• 1 1/2 teaspoons baking powder
• 1 teaspoon baking soda
•  
• Middle Layer:
• 1 cup semisweet chocolate chips
• 1/2 cup white sugar
• 1 teaspoon ground cinnamon
• 
  
• I know, it's a cake, but use the creaming method (butter, sugar, then eggs/sourcream/vanilla, then premixed dry ingredients).  It comes out as a doughy batter that is difficult to spread, but make the sacrifice; the sugar/cinnamon/chocolate chip should go in the middle between two halves of the batter.

• Makes a good 'coffee cake', which roughly translated from our childhood is 'cake we can have for breakfast even though it isn't really any healthier than a regular cake'.

• Bake at 350 in a greased 13x9.  Good luck with the timing; it's supposed to be 25-30 minutes, but it took me more like 40.  Toothpick test or shake it a little and hope it doesn't fall.
