If your little one is about to turn one and you're thinking of having a cake smash photoshoot, well great idea! Cake Smash photoshoots have become really popular over the last few years as a creative way to celebrate the special milestone. But along with having a first birthday, buying the presents, having a party, organising food, drink, decorations, etc, prices can add up really quickly. So a great way to save a bit of cash is to make your cake smash cake yourself! And the good thing is, you don't need to be Betty Crocker to do it :)



First things first, you'll need some supplies. Either Woolworths or Coles has a great selection of baking supplies perfect for the DIY'er. Here's what I recommend for a basic cake smash cake:


  • Pre-made mud cakes x 3. Usually choices of caramel, chocolate, or vanilla. Your choice.

  • Round cardboard cake board

  • Buttercream icing mix

  • Food colouring

  • Sprinkles or decorations

Now, you are ready to begin. Remember you can use as much creative flair as you want here. Your child is only going to destroy it anyway!


  1. Start by removing the icing from the mud cakes so all three cakes are flat on top. I often use a bread knife for this and get down so you're eye level with the cake to make sure it's even.

  2. Place the bottom cake on the cake board and centre it on the board.

  3. Prepare your icing (with your choice of colour) and using a butter knife or spatula, spread an even layer across the top. I usually make these layers approx 1cm thick.

  4. Place your next cake on top of the bottom cake and repeat the icing process. Do the same with the last cake placing it on top.

  5. Once your cake has been assembled, frost a nice even layer of icing all over the cake. If you are after a naked style cake, you can finish up here.

  6. If you want a more even style of frosting, thicker layers, or are attempting some piping work, place the cake in the fridge for 30 minutes for the icing to harden. This creates an easier surface to work with for further layers or decoration.

  7. For thicker icing coverage, remove the cake from the fridge and prepare more buttercream.

  8. For a nice smooth finish, you'll need a pallet knife to spread the icing evenly. You can pick these up from Spotlight or other cake supply stores.

  9. Now, it's time to decorate! Go crazy with sprinkles, flowers, or toy figures. I find that Pinterest is a great place to find inspiration and cake designs.

  10. Place the cake in the fridge to keep fresh, and remove it a few hours before eating to thaw up a bit.

And you're done! Step back and marvel at your creative work. You could go into business for this, right?

And the great thing is, these cakes usually only cost about $20- $30 to make. Gotta love saving money :)
