Apple-Spice Cake

I got this recipe from a book called something like 101 Things To Do With a Cake Mix.  I've only made this once, but it was yummy!

Apple-Spice Cake

1 spice cake mix
3 small apples—peeled, sliced, cored, and cut into small pieces
1 can (14oz) sweetened condensed milk
1 cup sour cream
1/4 cup lemon juice
1 tsp. ground cinnamon

Preheat oven to 350 degrees. Prepare cake mix batter according to the package directions. Stir apple pieces into batter, then pour into a greased 9 x 13-inch pan. Bake 28-30 minutes, or until toothpick inserted into center comes out clean.

Combine sweetened condensed milk, sour cream, and lemon juice. Take cake from oven and spread sour cream mixutre over top of cake. Return to oven; bake 8-10 minutes longer, or until done. Sprinkle cinnamon over the top. Cool. Refrigerate leftovers.
