Banana Passionfruit Lego Stormtrooper Cake

Attn nerds: It’s time for some serious pants-pissing.

Don’t judge me. It’s Mr. AA that’s the Star Wars nerd in this house. Here’s the wicked birthday cake I made for him the other week.

A quick note: While these recipes aren’t gluten free, I’ve tagged them as such because you can easily make them gluten free by using GF flour & GF icing sugar.
Banana Passionfruit Cake 5
Makes 1 loaf tin

Banana Passionfruit Cake
1 3/4 C Self Raising Flour
1/8 C Plain Flour
1/8 C Dessicated Coconut
1-2 t Ground Cinnamon
2/3 C Soft Brown Sugar, firmly packed
1/4 C Tinned Passionfruit Pulp
1/4 C Non-Dairy Milk (or more passionfruit pulp)
3 TBSP Vegan Spread/Margarine + extra for greasing
2 C Ripe Banana, roughly chopped*
2 TBSP Flax Meal/Ground Flax Seeds
6 TBSP Boiled Water

  • Pre-heat oven to 180C.
  • Mix together flax meal & boiled water. Leave aside to thicken. This will be your natural egg replacer.
  • Blend together the bananas, spread/margarine & milk in a food processor.
  • Place dry ingredients in a mixing bowl and stir. Sift the flour(s) if necessary.
  • Add the flax mixture, blended banana mixture & passionfruit pulp to the dry ingredients and mix with a wooden spoon until well combined and no lumps remain.
  • Generously grease a loaf tin with with some spread/margarine. Pour batter into the loaf tin. Bake at 180C for 45 minutes/until a toothpick or wooden skewer comes out clean). If you don’t have a strong, fan forced oven, you will need to cook this for a little longer. I suggest keeping an eye on it by pricking it every 5-7 minutes further from the original 45 minutes.
  • Leave to cool in the tin for a little while before tipping out onto a cooling rack.

*Make sure this is two even cups, not heaping cups, or your cake may be too moist and not cook properly in some areas.


Now the fun part! In most cases where you’d be carving a cake, you’d use something fairly dense like a butter cake or mud cake. In this recipe, the banana cake is fairly dense and allows for that. I woudln’t try it with a regular banana cake if I were you – it’s likely to crumble under your knife.

These are the three knives I used. You may not need to use such a variety on your own – you’ll be right so long as you have something serated and something pointy. If you have one that’s both, you’re in luck.

Banana Passionfruit Cake 4

Three loaves of cake was enough for me to create the Lego Stormtrooper and some Lego blocks surrounding him. I had a fair bit of scrap cake left over; the local family of magpies have decided they love me more than usual lately. I wonder why…

I was lucky enough to have a prototype to work with (yep, that’s an alarm clock). This is a photo of the first stage of cutting. Avert your eyes, children!

Banana Passionfruit Cake 2

This was assembly. I put together all my carved pieces and iced the crap out of them. Mr. AA helped me and we had a ball creating the liquorice finishing touches together.

Banana Passionfruit Cake 3

The [vegan] lemon cream cheese icing recipe below is enough to cover the whole lot, with a little bit left over in case you make any mistakes.

680g (3 tubs) Vegan Cream Cheese (I used Tofutti), at room temperature
4 C Icing Sugar
Juice from 1 lemon
1/2 t Vanilla Extract
1 t Powdered Egg Replacer (I used Orgran)
1/2 C Vegan Spread/Margarine

Beat all ingredients except for icing sugar. Add icing sugar, 1 cup at a time, and continue to beat with electric beaters for 5+ minutes. Separate into as many different portions as you need and add food colouring to each bowl. Refrigerate for an hour or two before icing.

I used “Wilton” icing colours in this instance and will reviewing them on the blog in the next few days. The manufacturer has assured me that they’re vegan and kosher, however I failed to ask if they were gluten free – sorry!

Also – one more look at this, so you can learn from my mistakes. I iced both the yellow & red Lego blocks while they were on the board. I made a mess on the aluminium foil. the blue & red blocks were iced separately on a chopping board, then carefully moved onto the main board with the rest of the cake. That’s definitely the way to go about it – it looks a lot neater!
