I have a wonderful quilt book called Coffee-Time Quilts (and don't even like coffee!) It has recipes mixed in with the quilt patterns.
Guess what they have a more G Rated version of? They called it Caramel Latte Cake. Here is their recipe:
1 pkg chocolate cake mix
3 eggs
1/3 c vegetable oil
1/2 c coffee liqueur
3 TBLSP instant coffee crystals, dissolved in 3/4 c water OR use 3/4 c strong brewed coffee
- Mix all these, beating well, and pour into a greased and floured 9 x 13 pan. Bake at 350 degrees for half an hour. Cool slightly, then poke holes in the top of the cake with the handle of a wooden spoon. Pour 2/3 cup sweetened condensed milk in all the holes, then pour 2/3 caramel ice cream topping over that.
Let it cool completely and serve with whipped topping and nuts.
