Here's a picture of a Pumpkin Cake I made for our Thanksgiving Dinner. It's made using two bundt cakes put together. The most difficult part was getting the buttercream icing the right shade of orange!
I used a Marble Cake recipe that I make every Thanksgiving and Christmas. This time I just made two of them, leveled them off, put them together with the Fudge Icing that I then used for a crumb coat. I then iced the whole thing with my orange icing. I added a fondant stem and leaves that I had made a few days ahead of time.
That's it! One of the easiest cakes I've made so far!
If you would like to try it and have questions, just let me know. I'd be glad to help.
