I found this pound cake recipe online, however, I've seen it in blogland too. I tried it first using the German Chocolate Cake Mix and the Coconut Frosting Mix. Sorry I forgot to make photos of those!
I was telling my granddaughter about it and she was questioning about the frosting being on the "inside" of the cake. ;-) That's when I started calling it the "Outside Inside Cake". I did change the recipe a bit ~ I use:
1 c. melted butter (not margarine)
1 c. liquid ~ for the chocolate I used 1/2 c. coffee & 1/2 c. water
Once all that is thoroughly mixed with your electric mixer...scraping the bowl, etc., then add the container of frosting and gently mix it in. Pour all into a well greased bundt pan and bake @ 350 for 50-60 min, depending on your oven. Caution: Make sure your bundt pan is large enough to use all the mixture. I found out the hard way that one of my pans does not! IF I use that pan again, I will bake part of the batter in a smaller pan or baking dish.
Here's another I tried for the grands for their Spring Break:
I used the same 4 eggs, 1 c./1 stick melted butter and added 1 c. buttermilk. You can choose to use the liquid you want ~ I just think adding some coffee to chocolate or milk/buttermilk is tastier and adds to the moisture quotient too.
The original recipe did not call for any type of frosting but I did add a drizzle of melted chocolate on the German Chocolate Cake and a bit of vanilla/cream cheese frosting on the other.
I plan to try the Lemon Cake Mix, Lemon Frosting next and add lemon juice and blueberries. :-) Tons of combinations you could try and it's soooo easy & extremely moist. Your efforts will truly be appreciated!
