Blueberry Cinnamon Coffee Cake

Preheat oven to 350 degrees.

Cream butter and gradually add in the sugar. Add eggs, one at a time, beating well after each one.

In a small bowl, mix together flour, baking powder and baking soda. Gradually add to butter mixture, mixing until it is all incorporated. Stir in sour cream and vanilla.

Spoon half of the batter into a greased and floured bundt pan. Smooth out batter with a spatula. Sprinkle with blueberries, sugar and cinnamon. Top with remaining batter and bake for about 45 minutes.

Let it cool in the pan for about 10 minutes and then transfer to a platter. Lightly dust with powdered sugar if desired.
