Easy Fish Birthday Cake

Firstly, it makes sense to check out some easy fish birthday cake options so that it’s not overwhelming for novice cake decorators (like me). Making a cake like this doesn’t have to be hard and if you’re short of time you’ll love these two options below.

To make the easy cake below you’ll need your favorite recipe for cake or buy a packet mix as they are so easy to whip up. Smarties or M&M’s in your choice of color or you could use Freckles / nonpareils like I did below.

You can be as colorful or as monotone as you like with this. You’ll also need buttercream icing or Betty Crocker frosting or similar.

It’s up to you what color you make it with food coloring…sometimes I like to leave it plain and let the colorful candy decorations stand out. I made the fishtail with one cupcake. Simply split your cake mix between one round cake pan and one patty pan for the cupcake prior to baking. Unless you feel like making lots of cupcakes at the same time.

Then once you’ve iced your cake simply decorate it until you are happy with how it looks. The kids can help you with this one too.

The next easy cake is another round cake and could easily be created with some plastic fish decorations. This is a great option for those people who are not skilled in cake decorating and the thought of creating a fish from fondant makes you break out in a cold sweat. I’m right there with you.

Simply check out this range of small fish toys that you could use as decorations. Just make sure you let any children (or adults) know that they’re not edible and are for decorative purposes only.

Fish Shaped Cake

These next two cakes are all fish shaped cake ideas. You could use a round cake and square cake to create the cake below. The fondant icing looks amazing for this fish cake design.

Or you could make a fun rainbow fish cake like the cake below by piping icing and you could use hardened white chocolate for the tail to make an overall fish shape.

The next cakes featured are a little more elaborate and they all definitely have an unmistakenly awesome fish cake design. This carp cake below looks amazing and if you can create a fish head from fondant or sugar paste the rest of the cake would be easy to make. Or you could find a large plastic fish toy to decorate it with.

This cake looks totally delicious if you are a chocolate lover.

This two-tier cake below looks amazing and has a fun Finding Nemo / Dory theme to it and would be great for any age.

Here’s a gorgeous feminine fish drip cake. The sugary detail around the bottom of the cake for sand also is a genius idea. This type of cake would also be amazing for a mermaid party.

If you are skilled at cutting out shapes in fondant you could have a go at this bright and fun looking cake below. You could be as detailed as you like with the fish shapes.

You could use a fish cookie cutter to cut out basic fish shapes in various icing colors and stick them all over a blue cake for an easy cake idea. The blue and yellow dots along the bottom of this cake look great as it can be hard to get that perfect finish with fondant and this can cover up any tricky areas.

Or you could tie around a blue ribbon as well to hide any imperfections.

If you’re looking for a fish themed cake for a first birthday or a cake smash check out these amazing cakes below. The matching cake smash mini looks awesome next to the main cake.

Such a cute idea for a first birthday party and fun cake smash photos to remember.

Likewise, this amazing first birthday fish cake would be a gorgeous idea for little boys and girls alike.

Fish Cupcakes

There are heaps of fun fish cupcakes below to inspire and delight. Some of these are super-easy to make and the kids can have fun creating them with you too.

I created these easy fish cupcakes pictured below and you can easily make them too by decorating with Smarties or M&M’s, nonpareils and rainbow sour straps or similar type candy.

These cupcakes look great with the blue swirled icing that looks just like waves with the fishtail peeking through.

This aquarium cupcake idea below is so very cute and would be a lot of fun to make. All you need is some rainbow sprinkles, some fish candy and colored buttercream icing.

 The kids (and adults too) will love these super cute Nemo cupcakes. It’s such a fun variation to the normal side on orientation fish cupcake idea.

The fishing line cupcakes are sure to be a winner. The swirled blue icing is perfect and simply attach a fish lolly to a pretzel with some string or piped icing.

If you wanted the look of a large cake but you want a quick option that still looks amazing you could make a fish cupcake cake. The blue and purple cake below looks exceptional and would be a fun cake to make in your favorite colored icing.
