Blueberry Cream Cheese Pound Cake

I got this recipe from my MIL. It was a yummy cake and I think it could make for an excellent addition to a brunch menu...or dessert.
*1, 8oz. pkg. cream cheese, softened
*1/2 c. vegetable oil
*1 18 oz. yellow butter cake mix
*1 (3 oz.) pkg. instant vanilla pudding
*4 eggs, beaten
*2 tsp. vanilla extract
*2 c. fresh blueberries
*powdered sugar, optional

Preheat oven to 325. Lightly spray Bundt pan with cooking spray and dust with flour.
Combine cream cheese and oil in a medium bowl, beat with a mixer at high speed until smooth and creamy. Add cake mix, pudding mix, eggs and vanilla. Beat on medium speed until well blended. Fold in blueberries and spoon into Bundt pan.
Bake 60 minutes or until wooden toothpick tests clean. Cool in cake pan on wire rack for 20 minutes. Remove from pan and cool completely. Sprinkle with powdered sugar to serve. Serves 16.
