Looking for simple buttercream Minnie Mouse cake ideas? Here is an easy Minnie cake design you can make. This is a simple sheet cake, cut out to follow Minnie's face image and decorated in simple star buttercream piping.
The best thing about this cake decorating idea is that you can apply the same techniques to create any Minnie Mouse design or image you like. I choose a face image, but you can easily choose a full image of Minnie.
Mickey Mouse and Minnie Mouse cakes are evergreen and so loved by children. This was my first Minnie cake and I was as excited to make it as the birthday girl was to have it for her birthday. The thing about this buttercream cake is that it was not baked in a specialty mold or cake tin. In fact, it was cut out of a rectangle sheet cake. And Minnie’s pose on the cake, it was directly from an image provided by the birthday girl and her mummy.
I decorated this cake using an image transferring technique I have used very commonly for many of my cakes (see my Godzilla cake, Nissan GTR car birthday cake). And it works very well for me especially when I have to decorate sheet cakes in customized shapes and images.
How to Make the Minnie Mouse Buttercream Cake
Main supplies to decorate the cake:
- Cake – the cake was baked in two 6 inches by 10 inches rectangle cake tins and joined to make a larger cake. Alternatively, the cake can be baked in a 12 inches by 10 inches rectangle pan. I had to bake 2 cakes and stick them together to get a large enough cake since I did not not have a larger cake pan. I used my butter pound cake recipe.
- Buttercream – I used buttercream as a filling as well as to crumb coat the cake. I also used buttercream to pipe Minnie Mouse design on the cake. I tinted it pink, ivory, black, and white.
- Butter icing – I used butter icing to cover the sides of the cake as well as the rest of the cake area outside Minnie Mouse’s image.
- Fondant - I used store-bought fondant and tinted it in pink for the cake border as well as the wordings on the cake.
- Piping tips and bags – I used Wilton tip 3 for the outlines and star tip number 16 for the stars. And I used Disposable piping bags. I always prefer using these when working with buttercream it is a daunting tasking having to wash off all the grease of the piping bags. Disposing of them is a much-preferred option!
The Minnie Mouse face template
- I started with the image. It was provided by the birthday girl's mom in soft copy. All I did was resize it to the size I wanted it to be on the cake and printed it out.
- After that, I traced it onto a parchment paper and cut it out along its outline. This is the template I used to carve and decorate the cake.
- Next was the cake. I did not have a large rectangle pan that could fit the size of Minnie’s image. Hence, I baked two rectangle cakes, filled and joined them with buttercream to make a larger cake measuring 10 inches by 12 inches.
Carving the Minnie Mouse sheet cake
- I then placed the Minnie Mouse template on the cake and carved out Minnie’s image. In doing this, I left about an inch allowance from the outline of the image to the sides of the cake.
- Once the carving was done, I removed all excess cake and lifted off the template. Next, was the crumb coat. I applied a thin layer of buttercream all over the cake and returned the template to the cake top again.
- Using my sugarcraft knife, I marked the outlines of Minnie’s image, including her eyes, bow, hands, and others onto the cake. When marking the inner outlines, I literally cut through the template to leave the markings on the cake, so it's important that the knife used is sharp. The thin coating of buttercream helps to make the markings on the cake more obvious, so that makes it easier when it comes to the piping work later.
- And by the time I completed all the markings on the cake, the Minnie Mouse template was already in pieces. I removed all the pieces and covered the sides of the cake with butter icing. The icing was not tinted; hence the natural ivory tint of butter was obvious.
Piping the buttercream image onto the cake
- Once the sides of the Minnie Mouse buttercream cake were done, I moved on to complete Minnie Mouse buttercream design on the sheet cake.
- I started with black icing and icing tip #3 for the outlines.
- And then, using tip #16, I covered Minnie Mouse image in buttercream starts, following its standard pink, white, ivory, and black colors. I used star piping tip #16 for most parts of Minnie Mouse except for her eyes and nose which were piped in buttercream using round tip #3.
- Once Minnie Mouse was completed. I cut out the ‘Happy Birthday” lettering in pink fondant, using alphabet cutters. And I rolled a long strip of the same pink tinted fondant for the cake border.
- Finally, I piped random tiny pink flowers on the sides of the cake and on the cake board.
- And that was how I decorated this Minnie Mouse buttercream cake.
