I did this for a good friend, that loves guns. This particular gun is in his collection and so I thought it would be fun to do for his birthday. I carved the cake out of a sheet cake. I cut all detail pieces out of gum paste and painted them, trying to get the look of gun metal. It wasn't exactly like I wanted, but very close. The cake is a Baily's Irish Cream Sour Cream Cake with a Baily's Bavarian Cream filling and covered in Satin Ice fondant.
