Chocolate Chip-Cinnamon Streusel Coffee Cake

Step 1: Preheat oven to 350 Grease an 11x7 pan. If you feel like there is to much batter you can use a bigger baking pan.

Step 2: In a medium bowl mix together the flour, baking powder, soda and salt.

Step 3: In a small bowl, combine 1/2 cup sugar and 1- 1 1/2 teaspoons cinnamon; set aside.

Step 4: Using a electric mix beat together the remaining 1 cup sugar and butter until fluffy. Beat in the eggs one at a time, then beat in the sour cream and vanilla. Fold in the flour mixture in two parts until just combined.

Step 5: Pour half the batter into the cake pan and sprinkle with half of the cinnamon sugar mixture and 1/3 cup of the chocolate chips.

Step 6: Spoon the remaining batter as evenly as possible over the filling. Spread gently and evenly. Sprinkle with the remaining cinnamon mixture and remaining 1/3 cup chocolate chips.

Step 7: Bake until golden brown and a toothpick inserted comes out clean 30 - 35 minutes.
