This is a heavy chocolate cake from scratch baked in a large cookie sheet. I doubled the frosting recipe and the milk chocolate ganache.
Cupcakes with the frosting piped on and a dollop of ganache and a preserved orange slice. Here is how to preserve the oranges. I took these to a church party and they got rave reviews.
Last Christmas my friend, Cheryl Johansen, brought brownies with an orange frosting and a chocolate topping to a party I was having.  They were much better than mint brownies, in my opinion, and Mike loved them.  Here is a combination of my recipe and hers with some variations.
Orange Frosting:  Beat together:
1 Cube real butter
1 T.  grated orange peel
3 T. fresh orange juice
2 T. whipping cream
3 C. powdered sugar or until desired
consistency
1/2 tsp. good natural orange flavoring (I like Kroger brand)
2-3 drops each of red and yellow food
coloring
Spread carefully on top of the cake
and smooth to prepare for the ganache.
Ganache 
Heat 1/3 cup whipping cream for 40
seconds on high in the microwave add 1 C. chocolate chips, dark, semisweet or
milk as desired.  Stir until the
chocolate is melted.  Let sit until spreadable and smooth carefully over the frosting.  I like to put the cake or brownies in the
freezer, after adding the orange frosting, until it is solid before spreading
the ganache,  Then I freeze a bit more to
make cutting easier.  
If you are making a cake or brownies
in a large cookie sheet double the frosting and ganache.
