18 Easy Birthday Cake Ideas for Kids and Adults

If you have a large family, it feels like you have a birthday every month. And when two members of the family share their birthday in the same month, it can feel overwhelming to come up with a new cake idea.

I don’t know about you, but I’m all about easy. In fact, when I’ve searched for cakes on Pinterest, I always put SIMPLE and EASY in the search. I tend to leave it to the last minute to create a cake.

But there have been times when I have gone to do a simple cake and it hasn’t turned out how I thought (looking at you hundreds and thousands cake!!)

These 18 Easy Birthday Cake Ideas are just that. Easy. Perfect for kids or adults alike. They are easy. Some are even bought cakes that have been hacked. Kelly and I have made these for our own families and the kids have absolutely loved them.

18 Easy Birthday Cake Ideas

1. Candy Box Cake

The Candy Box Cake is a loved favourite for all the family. You can tailor it to the Birthday person’s preferred lollies. You can check out this post on tips to assemble.

2. Chocolate Overload Cake

A similar concept to the Candy Box Cake, the chocolate overload cake is simply a Woolies mud cake, iced and surrounded by chocolate stick biscuits and whatever chocolates the recipient likes. In this cake we’ve gone Maltesers and chopped Tim Tams. Tie a ribbon around the cake to keep the surrounding biscuits in place and match with candles. This cake was recently made for my Dad’s Birthday.

3. Honeycomb Crunch Cake

Like the chocolate overload cake, this cake is more rustic and is simply a Woolies mud cake, iced and covered with broken choc honeycomb pieces. It can be turned into a construction cake by adding trucks and earthmoving toys, if you have them.

This is a simple cake for a sports loving kid or adult. You can make any sports ball from a round cake, but this is an example of a basketball cake using Kit Kats and Smarties.

6. Peppa Pig Muddy Puddles Cake

This cake was made for one of my kids when they were going through a Peppa Pig phase. I used a ring cake tin and filled the middle hole with chocolate mousse. The scene was set with the kids figurines. So easy and effective.

10. Tangled/Rapunzel Donut Cake

My husband and I made this cake for one of our daughters as she was OBSESSED with the movie Tangled. This was the cake we made for her party. We baked the cake and it came out with a weird side rise. This made the perfect base for the cake. We then used strawberry iced donuts for the tower and decorated with store bought pen icing.

16. Sprinkles Number Cake

This cake is simple if you don’t have time to muck about with decorating a cake. Ice a baked cake. Trace the Birthday number on a piece of baking paper. Cut the number out and lay this on top of the cake and sprinkle. Once the baking paper is moved away, the number will be left on top.

17. Flowers and Strawberries Cake

18. Sour Worm Mud Cake

This cake was recently made for my 5-year-old’s Birthday. It was decorated by the kids. The Trolli sour worms were given eyes. Smarties and lady bugs were added to give an outdoor and fun effect to the cake. Kmart has a great section of props which can be used to decorate a cake. The Happy Birthday topper has been kept for another cake in the future.
