The 25th birthday is a major milestone for a young adult and deserves recognition. The person celebrating her 25th birthday is celebrating adulthood while still enjoying a bit of childlike merriment. Decorate a 25th birthday cake with elements that are both grownup and youthful.
Make It Playful
Bring a playful aspect into the 25th birthday cake by making a layer cake, with each layer being smaller than the layer below it for greater drama. After icing the layers, add bright colored stripes made from marzipan, candy dots, and curly lettering created with a icing piping tool. Add 25 sparkler candles to the top.
Silver Anniversary Theme
The 25th birthday is technically the 25th anniversary of birth, so consider making a cake in a silver anniversary theme. Create a simple sheet cake, but decorate it meticulously with smooth layers of icing, and delicate silver piping along the edges with silver lettering. Buy silver cake decorating glitter and highlighting dust to decorate the cake. Top the cake off with a birthday topper such as princess tiara, or draw amusing characters with the elegant silver piping. Add sparkler candles for an exhilarating presentation and to add a challenge to blowing them out.
The 25 Cake
Bake a 25th birthday cake with the numbers 2 and 5 being the dominant part of the cake. Start with a sheet cake for the first layer. For the second layer, use number cake pans, and make a 2 cake and a 5 cake. After icing the first layer, place the numbers on top and ice the numbers as well. Decorate the cake elaborately, using piping to border the letters, and add candy confetti to the base layer.
25 Cupcake Cakes
Make a cake from 25 square cupcakes. You could make round cupcakes, but square cupcakes give you more versatility with the finished design. You can push them together and ice the cupcakes as a single layer, placing one cupcake--decorated with a 25--on top. You can arrange the cupcakes into letters or numbers, more specifically, the number 25. For a little more elaborate idea, number each cupcake 1 through 25 and place a tiny object on top of each that relates to the age that each number represents. For example, put a miniature diaper on number 1, a tiny tricycle on number 5, toy car keys on number 16 and a mini diploma on number 18. Relate the decorations to the years of the birthday person's life.
