Devil's Food Surprise Cake

Ingredients

Cake: 
1 Devils Food Cake Mix (mixed according to directions only adding 1 egg more) 
1 jar Maraschino cherries drained and chopped coarsely 
1 8 oz (224 grm). pkg. of cream cheese 
1/3 cup (80 ml) sugar 
1 egg 
1 tsp (5 ml). vanilla 
1/2 pkg. of 12 oz (336 grm). bag miniature chocolate chips. 
Icing: 
1 12 oz (336 grm). bag chocolate chips 
3/4 cup (175 ml) sour cream 

Instructions

Cake: Mix cake according to directions only adding 1 additional egg. Pour into two greased and floured cake pans. Mix the cream cheese, egg, sugar, and vanilla together until smooth and then add chips and cherries. Drop in tspfuls across the cake batter distributing evenly--DO NOT ATTEMPT TO SMOOTH. Bake until set about 40 min or until cake tester comes out clean. Cool and frost. Icing: Melt chocolate chips in microwave just until melted according to package directions. Stir until smooth. Add sour cream and mix well. Mixture will have chemical reaction that will cause it to become a beautiful dark color and get very glossy. Frost/ice rather quickly as this icing will set up but never loses the wonderful smooth texture.
