Cinnamon Swirl Coffee Cake

Cream together butter, sugar, eggs and vanilla.

In a separate bowl, mix dry ingredients.

Alternately mix flour and sour cream into butter mixture and beat until smooth.

Mix filling ingredients together.

In a buttered and floured springform pan with a removable bottom, spread 1/3 of the batter.

Sprinkle it with 6 Tablespoons of the filling mixture. Repeat this layering process two more times.

Bake it in a preheated 325 degree oven for about 1 hour. I baked mine for 55 minutes, but we liked it slightly gooey in the center.

Place it on a rack to cool slightly before springing it free from the pan. Enjoy a warm slice!
