Phew – the posts are coming thick and fast, but I knew I’d be leaving you all on a cliffhanger if I didn’t blog about the final result!
In the last two posts I talked about making my gran’s 80th birthday cake, and making the passion fruit curd to fill it with. In this post, I’ll show you how to (really easily) make the buttercream icing and put it all together. The only ingredients at this stage are for the icing and decoration, and there are only three of them!
INGREDIENTS: 750g icing sugar, 375g soft unsalted butter, 100g white chocolate. (‘Happy Birthday’ candles are optional)
- Make sure the butter is soft and use a hand mixer to blend it a bit in a big bowl. You might find it easier to do this icing half at a time, as moving this much butter around is tough on the old arms!
- Once the softened butter is mushed a bit, add the icing sugar a little at a time, using the beaters to mix it into the butter after each addition. Don’t be tempted to put it all in at once, you’ll create an icing sugar cloud, sneeze a lot and make a very big mess.
- When all the icing sugar is mixed in, beat until completely smooth and soft.
- That’s it! You can add a splash of vanilla essence, a hit of lemon zest or anything else that takes your fancy, but this is the basic ratio of butter/sugar for buttercream icing.
ICING THE CAKES:
- Cut each cake horizontally through the middle (its easiest with a serrated knife) and spread a thick layer of the passion fruit curd over the bottom layer of each cake.
- Then spread a layer of buttercream over the curd. It doesn’t matter if they mix a little bit, it’s going to be covered.
- Put the top of the cakes back on their bases.
- The larger cake will be your bottom layer. Its easier to pop it on your serving plate/stand before you start icing the exterior, so do that now. I also placed the bottom cake upside down, so that I had a very flat surface to place the next cake onto. It doesn’t matter if the base is a little wonky as you can hide that with icing, although it shouldn’t be too bad if you flattened the top as suggested in part one.
- Buttercream the top of the bigger cake and then place the sandwiched smaller cake on top. Try and get it central.
- Now buttercream the top of the smaller cake, then go round the sides of both cakes, making sure they are completely covered.
- TIP: If the butter wasn’t quite soft enough and you’re still finding the buttercream a bit hard (this can make it tricky when doing the sides) add a tiny splash of boiling water and beat into the mixture. That will soften it nicely but will allow it to harden again when it cools.
- Make sure you fill in any gaps between the two cakes, and any gaps at the bottom. A good idea is to use palette knife once the whole cake is covered. Dip it in hot water and then run it along the sides to create smooth edged and a smooth top.
- To finish it off, melt the white chocolate in the microwave, or over a pan of simmering water if you prefer. While this is melting, get a sheet of baking paper, and place on a tray.
- Once the chocolate is melted, pour into a piping bag with a pinpoint round nozzle – the sort you’d use for writing letters.
- Decide on a shape and then pipe outlines onto the baking paper, followed by some patterns inside the shape to connect all the edges (for stability). I went for tall triangles and filled the insides with zigzags.
- Pop the tray into the fridge until the chocolate has set. The pieces will then come away from the paper really easily.
- How you use them is up to you. I used my tall shapes to stand on the lip between the two cake layers, but they’d also look great forming a sort of teepee on top if you didn’t have candles.
So there you have it. Quite simple really, but very effective. Other ideas could include using milk chocolate for the decorations as a contrast, different colours of icing for each layer or even ombre icing if you were feeling really adventurous!
If you are looking to feed a crowd this is a great cake. By the time we served it everyone (40 plus people) had eaten a lot of food, so we cut it into small squares, like you’d get at a wedding. It probably would have fed twice as many people and several people went home with a chunk! This can also be iced the day before, covered in clingfilm and left somewhere cool. So if you have a big party to plan, you can get this done ahead.
There will now be a short break for the baking bandit. Quite a lot to do in the next few weeks. But its my dad’s birthday at the end of the month and we’re having another party, so I’m sure there will be another cake.
Most importantly – a good wedding cake? I am just looking for something small and white to cut, and some of our friends will hopefully provide a few extra cakes so that we can feed everyone.
Sweetness and that fuzzy ‘too much sugar on my teeth’ feeling to you all,
Hello all and happy Monday!
Well the party was a great success, the birthday cake applauded and everyone had a wonderful time. I have to pay special homage to my cousin’s wonderful chocolate cheesecake, which was my personal favourite of the dessert table! Now that I’m back home, back to work (boo!) I thought I’d update the blog with two posts to complete this celebration cake bonanza.
Once the cakes from part 1 are ready to go, you need a filling. Now previous posts about the joys of lemon curd hint at my favoured cake filling, but I wanted something that was a little more exotic for a special occasion. Passion fruit always make me think of my grandparents. My granddad is South African, my grandparents lived there for a bit in the 1950s and the flavours of the southern hemisphere were always present in their house – or at least in their fruitbowl! So what better way to fill my grandma’s birthday cake.
Passion fruit curd adds an exotic zing of sweet and sharp and works well with the lemons in the cake and the sweetness of the icing. This recipe is adapted from the ever trusty and reliable bbc goodfood.
INGREDIENTS: 9 ripe passion fruit, 3 large eggs, 140g butter, 200-250g caster sugar, 2 1/2 tablespoons cornflour, a few squirts of lemon juice to taste.
TIP: The passion fruits must be ripe to get the right sweet/sour balance, so you might want to buy them about a week before you plan to use them. The wrinklier the better – a smooth skin is an under-done fruit!
- Cut the passion fruits in half and scrape all the seeds and pulp into a food processor. Pulse it a few times, which will separate the pulp from the pips. Then pour the mixture through a sieve into a saucepan set over a low heat. Use the back of a spoon to push as much of the pulp through the sieve as possible.
- PIPS OR NO PIPS? Now, at this point, most recipes I came across suggested reserving a few spoons of pips to put back in at the end. I’m not a fan of this personally, but you can do if you fancy. Pip look nice in a jar of homemade curd given as a present, but they are a tasteless and crunchy annoyance that is most likely going to get stuck in your teeth. As this curd was going into a cake (where you most certainly don’t want a crunch annoyance) I didn’t bother.
- Add the butter, cornflour, eggs and sugar to the pan and continue to stir over a low heat until everything is fully dissolved/melted.
- TIP: The reason I’ve given a range on the quantity of sugar is because it’s all about taste. If your fruits are still a bit too sharp you’ll need more sugar, if they are very sweet, you’ll need less. If you are unsure use about 225g and then use the lemon juice to adjust the taste.
- When everything is dissolved and you have a smooth mixture you need to keep on mixing. Don’t be tempted to turn up the heat to get it all thickening quicker. All you will make that way is scrambled egg. Keep mixing, remembering to scrape along the edges of the pan, and after up to 10 minutes (maybe more!) your mixture will thicken nicely.
- TIP: If you are making this curd to spread on toast, or stir into porridge, you might want a runnier consistency than I needed for filling a cake, so use 1/2 tablespoon less of cornflour.
- While it is thickening taste it. If you think it’s too sweet, use some lemon juice (a dribble at a time) to balance it out. If it’s too sharp use a little more sugar but make sure it dissolves. Don’t be tempted to squeeze in a whole lemon straight away – it’s a strong flavour which will take away the passion fruit taste.
- When its a good thick curdy consistency, take it off the heat. Unless you are going to use it immediately, when it has cooled decant into jars (remember to sterilise them!) and it will keep in the fridge for about 2 weeks.
And there you have it! An exotic but homely passion fruit curd all ready to be spread in a cake, or eat on toast, in yoghurt… the possibilities are endless!
