I loved making my daughter's Minnie Mouse/zebra cake and party a few years ago, so when my sister-in-law wanted a similar party and cake for my niece for a first birthday, I was excited to get working on the cake. She loved the cake I had made previously, but gave me permission to do what I wanted as long as it was similar. I kept some similar elements, but revamped the design a bit, and I loved the outcome (I think I love it better than the other cake).
black chocolate marshmallow fondant.
A cute bow on top helps make it Minnie instead of Mickey :)
The pink and white polka dot ruffle is just a piece of pink fondant that was cut into a circle, then the edges were rolled a little to thin them out and make a ruffle appearance. After putting it on the cake I went around the cake and helped the ruffle out a little by doing a pie crust pinch carefully along the edges.
Miss Caroline was a big fan of the chocolate fondant. She went to town on that head.
