Dessert idea help

I’m part of a rotating football watching get together in which the host makes a main dish and the guests bring appetizers, side dishes and dessert. Yesterday and again next week I’m on dessert duty. Yesterday it was a devils food cake with chocolate pudding and crumbled Heath candybar between layers and a sour cream chocolate frosting and more Heath crumbles on top. (I know, I should have provided insulin as well).
So anyway, the recipe I used for the frosting was for more then I needed and I now have a 16 ounce container of very tasty chocolate sour cream frosting in my fridge. Looking for ideas for using this other then cake or cupcakes.
What ya got?

Make a plain vanilla cheese cake and swirl the frosting into the cake before it bakes? Maybe use Oreos instead of graham crackers for the crust?

Teaspoon, sofa, dim lights, episode of “Firefly.” Begin shoveling.

Could you beat in some additional liquid and use it to make a trifle of some sort?

Could you stir in something to give it more body (grated dark chocolate, finely ground nuts) and make truffles?

I can’t believe I am suggesting it, since my first thought was crepes or pancakes, but you could use it as a dip for bananas or apples. Bonus if you sprinkle in some walnuts. You know, for protein.

Some sort of sandwich cookie? My sister does this thing with peanut butter cookies and a chocolate filling of some sort.

Get some strawberries or raspberries. Whip up some heavy cream. Make a parfait with layers of chocolate, berries, and whipped cream.

More devils food cake with chocolate pudding and crumbled Heath candybar between layers and a sour cream chocolate frosting and more Heath crumbles on top?

Because that sounds really good.

So I went with a vanilla cheesecake, chocolate graham cracker crust and the sour cream frosting. Still some frosting leftover so made “sandwiches” of graham crackers and the frosting.
