Cheese and chocolate tunnel cake

So, I saw this recipe & I had to try it. Even though I don't like chocolate cake. I know I'm weird. It was so simple & easy to make & tasted delicious. I served with with whip cream & vanilla ice cream.

1 cake mix, two-layer chocolate with pudding (plus eggs & water that is called for on the box)
1/3 c butter
16 oz cream cheese, softened
1/2 c sugar
2 eggs
2 tsp butter, melted
2 oz semi-sweet chocolate
2 tsp corn syrup

Preheat oven to 350 degrees. Prepare cake mix according to package directions, substituting butter for oil; reserve 1 cup of batter.
Pour remaining batter into a 12 cup greased and floured fluted tube pan.
Combine cream cheese and sugar, mixing well at medium speed on an electric mixer until well blended; blend in eggs, one at a time.
Pour over batter in the pan; spoon reserved batter over cream cheese mixture and bake 1 hour or until toothpick inserted in center comes out clean. Cool 30 minutes; remove to a wire rack.

Combine melted butter, chocolate and corn syrup in a small saucepan. Cook over low heat until chocolate is melted.
Pour over cooled cake.

Note- due to the fact that there is dairy in the cake. If you are serving the cake that day, I would think it is ok to leave out. However, I would refrigerated any leftovers.
