How to Make a Dinosaur Birthday Cake

Kids love birthday cakes and dinosaurs, so why not combine the two? Read on to find out how to make dinosaur birthday cakes.

Birthday cakes: kids love them – eating them and making them. They love the mess, they get a delicious treat at the end of it, and all while they’re learning a useful skill for later in life. Fun cakes are the best cakes, so why not rally your kids and make some dinosaur birthday cakes? This activity is creative and delicious, and perfect for a rainy day.

Not sure how to make a dinosaur cake? Here are some dinosaur cake ideas to get you started. If you’re short on time or you’re not the most confident baker, you can use a cake mix instead of making the whole thing from scratch. It’ll still taste great!  

Step 1: Make the cake

If you’re making your dinosaur cake from scratch, you will need:

  • 225g self-raising flour
  • 4 eggs
  • 225g butter
  • 225g caster sugar
  • 1 teaspoon baking powder
  • Two equally-sized round cake tins (20 or 20cm tins would work best)
  1. Preheat your oven to 180°C
  2. Measure all the ingredients together in a large bowl and mix them together. You can use a regular whisk for this, or an electric one. Make sure you keep an eye on your young ones whilst you mix – raw egg could be bad for them.
  3. Grease your baking tins. Kids love this part, so hand them some butter and a paper towel or pastry brush and let them at it!
  4. Pour your dinosaur cake mixture into the tins, making sure they’re about the same level.
  5. Put them in the oven until they’re golden brown. This should take between 15 and 25 minutes. Make sure a responsible adult is charged with taking them out!
  6. Turn the cakes out of their tins onto a cooling rack and leave them for about half an hour until they’re cool enough to touch. You can speed this part up by putting them in the fridge, if you like.

Step 2: Make the icing

Start by thinking of a few good dinosaur cake ideas with the kids. What kind of dinosaur are you making? A diplodocus? A T-Rex? A stegosaurus? A triceratops? Think about the colour, too – this will be important for the icing. To mix up the icing you will need:

  • A see-through bowl
  • 140g butter, softened
  • 280g icing sugar
  • 1-2 tablespoons milk
  • Food colouring in your chosen dinosaur colour
  1. Beat the butter until it’s soft. One of the grown-ups can help it along in a pan or the microwave for 10 seconds if necessary. Add half of the icing sugar and beat the mixture until there are no lumps.
  2. Add the rest of the icing sugar and a tablespoon of milk and beat the mixture until it’s creamy. Add a second tablespoon of milk if necessary.
  3. Stir in your food colouring until it’s mixed in all the way through. This is why a see-through bowl is useful.

Step 3: Create your dinosaur

In this stage of dinosaur cake construction, you’ll need to do make your final decorations and put everything together. Just follow our steps and give your child a happy dinosaur birthday!

  1. Cover your cakes with icing – adding some in between the two cakes for extra filling. You can even add sweets or chocolate chips if you like.
  2. Consider using a different coloured icing on the top of your cake to create a landscape. Green is great for grass, or you can use blue to represent the sky if your dinosaur is going to be flying.
  3. Add texture to your icing while it is still soft by using a fork or spoon. You can create “spikes” in the icing to symbolise grass or maybe use a spoon or piping bag to add some white icing in the shape of clouds.
  4. Finish the decoration of your dinosaur birthday cake with the most important character – the dinosaur! You can make your dinosaur from ready-to-roll marzipan and mould it to any shape you like. For a simple dinosaur in a seated position, follow these basic steps:
  • Create a large oval shape for the body, and a small round shape for the head
  • Attach the two sections together with a little water
  • Make smaller cylindrical shapes for the feed, and a long one for the tail
  • Use a skewer to make indentations for the claws or scales on your dragon
  • Create wings by moulding two larger pieces of marzipan into triangles
  • Make smaller triangles to create ears, and maybe scales along the spine
  • Stick your marzipan design together by applying a little pressure and water
  • Add finishing details, such as eyes, nose, and mouth, using liquid icing

There you have it: some dinosaur cake ideas for you and your kids to experiment with. Have fun!
