Happy Birthday Cake Toppers – 21st Birthday Celebration Ideas

21st birthday cake

One of the most important days in a kid’s life is their 21st birthday, so it makes sense that they should get a memorable cake for this special day. Below are just some of the many ideas for an enjoyable 21st birthday cake, but if you want to design the ultimate cake for your little guy or gal, you can certainly make the day special by yourself. You could also make a fun novelty cake to represent your favorite things or make more modern and elegant cakes for a more sophisticated taste.

21st birthday cake – Design

A great design for an all-out party would be a cake with a twist. Instead of frosting the entire cake in white frosting, why not try using different colors for the frosting on the cake. If you have a girly color palate for instance, using pink and black frosting may be a nice idea. For men, a more masculine looking cake with blue frosting might be the way to go, using brown and green frosting.

A very classic design for a 21st birthday cake is a birthday star topping. There are many different ways that you can do this, but the most fun is to use two different colored candles and arrange them like a birthday star. One of the most popular ways is to use a three dimensional cake star that is lit from underneath. With this method, you do not have to worry about getting in the way of the cake being decorated. For a more modern look, a cake star may also be achieved simply by placing a circle of frosting on top of a round cake.

The 21st birthday cake can also be decorated in chocolate or plain white frosting. If you wish to add another touch to the cake, there are fondant icing tips available to help you decorate the cake as you like. Fondant icing adds an elegant touch to many types of cakes, and it can be purchased in rolls or in sheets. Fondant icing makes the decorating job on a 21st birthday cake easy, because it comes already prepared.

21st birthday cake – Funfetti Cake

Another fun thing you can do with a 21st birthday cake is to turn it into a funfetti cake. Funfetti is basically fondant dust which you paint and spread onto the cake. You can buy funfetti cake dust from any store that sells edible dust, and then just sprinkle it over the cake. This adds a lot of fun to an otherwise plain cake. It looks like the icing is sprinkled across the entire cake, and it is rather fun to see the patterns and colors come to life.

When you want to recreate a tradition, you need to make sure that your 21st birthday cake is no different than the others at the party. One way to make this easy is to purchase decorations that are similar. For example, if you are making a Sponge Bob birthday cake, you can purchase a blue plate and fork and a sponge bob cake to go with it. You can also find green cupcake liners in shapes of birds, grapes, hearts, and more. These are often used to replicate the favorite character.


If you want to be a little different and not follow any tradition, you can always design your own cake. It might sound a bit strange at first, but after seeing how much fun it can be to create your own decorations, you will likely not mind. If you want a more realistic looking happy birthday cake topper, you might try making one yourself. The most difficult part is probably the planning part of it all. However, once you get started, the process only gets easier and more involved.

One fun idea is to use hot glue guns to turn your cake into a character. If you have never done this before, it is really simple. All you need is hot glue, a topper, and a food color. If you want to turn your plain cake into a superhero, simply pick up some hot glue, hot chocolate, and fondant icing. You can even put some fake blood or something gross like that on the top of the character. After that you simply put it on your cake, spray it with food color, and bake it.
