To cut back on calories (and save yourself some work), bake the cake in a 9X13 cake pan as a sheet cake and make half the amount of frosting to go on top. Also, for a more moist and goopy version, prepare the sheet cake. In a small saucepan bring 1/4 cup honey, 1/4 cup brown sugar and 2 tablespoons of butter to a boil. Remove from heat. Poke some holes throughout the sheet cake and drizzle the honey glaze evenly over it. Allow to cool completely and then frost (remember, half the recipe amount for the frosting). Note, I haven't actually tried this version, merely conceptualized it in my mind, but I think it would work ;) Note: For chocolate frosting, add a couple of tablespoons of good quality cocoa powder.
*Variation: Add Nutella to the frosting
*Another variation: Pour some chocolate ganache over it for ultra decadence!
