Let’s Make A Birthday Cake!

Well, you may have seen on Instagram or Twitter recently that I decided to make my boyfriend, Cameron’s 21st birthday cake – admittedly I was terrified it would go wrong!

He had one requirement, chocolate, chocolate and more chocolate and I had great, duck shaped, plans! A quick explanation re. ducks, Cameron exclaimed one day to me that he would like a pet duck, unfortunately we aren’t allowed pets at the flat so instead me and my sister got 84 rubber ducks for him instead! Check out the Twitter thread and his first reaction here.

I started off by making the chocolate decorations – bubble wrap chocolate, solid chocolate discs and a chocolate curl. They’re super simple to make too!


Chocolate Decorations:

Bubble Wrap Chocolate:
  • Place bubble wrap (any size) onto a flat tray / container.
  • Melt chocolate, I used white first then milk, then swirl across the bubble wrap till covered.
  • Set in the fridge.
  • Break off into bubble wrap chocolate shards! Enjoy!




Solid Chocolate Discs:
  • I’m not 100% what the container I used is called but anything similar will work, even an ice cube tray!
  • Melt chocolate and drizzle over the container, as shown above I used white on one side and milk on the other – this would create the drizzle effect on top of the chocolates.
  • Fill the containers with the opposite chocolate to the drizzle.
  • Set in the fridge, I put mine in the freezer for about half hour to get them out of the container easier.
  • Enjoy

I also drizzled some melted chocolate onto a piece of grease-proof paper and placed into an old kitchen roll tube – it makes the chocolate curl as it sets! You can see it on the finished cake later!


The Cake Itself:


The cake recipe I use is from one of my Mum’s recipe books and it’s super simple and quick to make.

I obviously made two chocolate cakes and I was very happy with how they turned out in the end.

If you want to make your own I have added the recipe and ingredients below.

  • 175g Soft Margarine.
  • 175g Caster Sugar.
  • 3 Eggs.
  • 175g Self-Raising Flour.
  • 1 1/2 x 5ml spoons Baking Powder.
  • 2 x 15ml spoons Cocoa Powder.
  • Set the oven to 160 degrees C (325 degrees F).
  • Line 2 x 18cm sandwich tins with grease-proof paper.
  • Put margarine, sugar, sifted flour, eggs and baking powder into a bowl and mix till smooth.
  • Add extras (aka cocoa powder).
  • Spoon the mix equally into the sandwich tins, leaving a small indentation in the middle of the cake mixes ensures it cooks level.
  • Bake for 25-30 mins, then leave to cool.

Decorating Time:

Now, this was the most exciting bit! Having already pre-made the chocolate decorations to ensure they set in time, I just waited for the cakes to cool and then got to work. Making a simple buttercream of margarine and icing sugar, with cocoa powder giving it the chocolate flavour I spread that on the middle, top and sides of both cakes!

Can you see all the toppings in the background?

Obviously, from Cameron’s request it was chocolate, chocolate and more chocolate so I obliged, placing white and milk chocolate fingers alternately around the edges of the cake and layering the top of the cake with the chocolate decorations I made previously, chocolate buttons, malteasers and of course, a chocolate duck!

The Big Reveal!

After waking up at 8.30am on the Saturday morning, by 3.30pm the cake was finished, I was covered in chocolate and very happy with my finished creation! I surprised Cameron with the cake at a family BBQ to celebrate his 21st birthday on Sunday and we all had the best time – despite the torrential rain!

It’s safe to say, he definitely enjoyed the cake although he may have exclaimed suddenly when he caught a glimpse of his little duck friend – I have ‘Mr Simms Olde Sweet Shop’ in Worthing to thank for him!
