Preheat oven to 325 degrees and grease a bundt cake pan with non-stick spray.
In a medium bowl, combine the cream cheese, sugar and flour and beat with mixer until creamy.
Pour half of the cake batter into the bottom of your pan. Spoon the cream cheese filling around the center. (For more precise placement you can use a piping bag. ) Leave a border on the outside and inside edges of your cake. Pour the remaining batter over the top and spread around evenly.
Bake for 50-55 minutes or until a toothpick inserted comes out clean. Cool for 20 minutes then invert to remove cake from bundt pan. Cool completely on wire rack.
To frost the cake, remove the foil from the frosting container and remove the lid. Place the frosting into the microwave and heat for 10 seconds, take it out and stir. Continue cooking at 5 seconds intervals until desired consistency has been reached. Carefully pour or spoon the frosting over the top of your cake.
