Chocolate cake, cookies and cream filling, covered in vanilla buttercream with mmf accents. Had trouble with bulging with this cake, but have since learned (thanks to so many knowledgeable cakers on this site!) to dam with a stiff buttercream. Wish the monogram had turned out a little better. What I didn't get a picture of was the end result cake-I made 3 silver "Wolverine" claws out of fondant, and made 3 slash marks across one side of the cake, and then had the claws coming out of the slash marks. My niece, Nikki, was really into that movie at the time and this was for her birthday-she loved it!
