To be honest, I would never have made the strawberry meringue buttercream that makes this cupcake if it wasn’t for the beautiful photo in Martha Stewart’s cupcake’s book. I mean, the very name, Strawberry Meringue Buttercream sounds pretentious, preposterous and… p,p,p… what other word am I looking for that starts with ‘p’?. Come on, be honest. How many of you had heard of meringue in a buttercream before?
- a new/complicated technique
- not being put off by a bit of baking equipment that I don’t have
- and getting over my dislike of frosting
Having made the recipe and tasted it (so delicious!), please don’t get put off making both parts of this recipe. Particularly the pretentiously, preposterous (I’m joking now) strawberry meringue buttercream. This buttercream is YUM!
There were four noteworthy moments that I’d like to share:
I borrowed a Kenwood Mixer, which we nicknamed “Kenny”, and duly fell in love with it. I must confess that after the first time that I used the Kenwood, I sent a text message to Sarah, his owner, which stated “Kenny is a dream!” Kenny definitely made the experience a much easier and better one. But, as I have to remind myself now, if you don’t have an equivalent, then use the electric mixer.
You’ll want to use a big bowl to make the cake mixture. A glance of some of the ingredients list gives it away: 2¾ cups of flour. 2 sticks of butter.
Martha says that this makes 36 american sized cupcakes. I read in the Hummingbird bakery book that UK muffin tins are the same size as US cupcake tins. More cross-pond confusion. So, I duly baked these in a UK muffin tin, and excitedly found some pretty pink muffin cases to bake them in. In the end I made 42, but it could be that I underfilled the cases a little bit.
I still don’t quite get what the UK substitute is for US all-purpose flour. The baking forums are ambivalent on this. Martha’s recipe explicitly states that the ¼ cup of cake flour shouldn’t be self-raising flour. By that instruction, I deduced (rightly or wrongly) that I shouldn’t use self raising flour for the all-purpose flour bit. Unfortunately, at that point in my 6 hour cupcake bake-athon, I realised that I didn’t have enough plain flour. And then my kitchen scales started playing up. Anyway, to cut a long story short, I used mix of plain and self-raising flour (ratio unknown), and substituted the cake flour for cornflour. Martha – I deduced by cakeflour that you wanted a flour that would create a lighter texture to it.
So, Martha. My question to you: did I commit a great baking sin?
Anyway, back to Martha Stewart’s Strawberry Cupcakes, adapted by moi. And I converted the recipe into grams for my UK readers.
Ingredients for the Strawberry Cupcakes
- 340g self-raising flour
- 35g cornflour
- 1 tbsp baking powder
- 1 tsp salt
- 225g butter, softened and cubed
- 375g caster sugar
- 3 large eggs + 1 egg white
- 1 cup whole milk
- 1½ tsp vanilla extract
- 2 cups finely chopped strawberries – about 20 strawberries.
1. Preheat the oven to gas mark 4/180C/350F. Line the muffin tin with paper cases.
2. Measure out the dry ingredients and sift together into a medium sized bowl. That’s the self raising flour, cornflour, baking powder and salt. You don’t have to sift, but the sifting helps it to be a lighter cake.
3. Cream the butter and sugar together until light in colour and fluffy in texture. This normally takes between 5-7 minutes with an electric whisk. If you’re using a mixer then use the beater attachment.
I think this is the moment I fell in love (again!) with the Kenwood mixer because I could just leave it to work its magic whilst I read the instructions again and got the eggs, vanilla, measured out the flour…
4. Add the vanilla extract at this point (one of my variations to Martha Stewart. I think that it helps to mix the flavour in evenly into the mixture). Then add in the eggs on a slow speed, one egg at a time with a tablespoon of the flour mixture, to prevent the mixture from curdling.
5. Now mix in the remainder of the flour mixture into the wet batter. Then pour in the milk and continue to mix well.
6. Finally add the chopped strawberries and mix the cake batter with a spatula or a wooden spoon.
Using a tablespoon, dollop out the cake mix into the prepared muffin cases. For each of the muffin cases, I estimated 2 dollops of the tablespoon worked well.
Bake in the oven for about 15-20 minutes, turning the baking tins once in the baking, so that the cupakes have an even bake. Test them with a tester/sharp knife and if it comes out clean, they are ready. Let the baked cakes cool in the muffin tray for 5 minutes and then cool completely on a wire rack.
Besides, Ruth sold it to me, “This post also includes the recipe for the absolute best cupcake topping in the world – meringue buttercream frosting – I can eat this straight off the spoon! It’s definitely worth the effort and once you’ve tried it you’ll never go back to ‘normal’ buttercream!”
Okay, Ruth. Let’s give it a go and see whether it’s worth the effort.
It is. I don’t normally like buttercream frosting because it’s too rich and sweet, but I make an exception for this one. The addition of the meringue means that it feels much lighter and airier to eat. Also on the decorating front – it holds it’s shape really well. Once again, probably because of the meringue.
So, here’s my version of delicious Strawberry Meringue Buttercream, adapted from the Pink Whisk. From another of Ruth’s posts, I’d seen that she’d used Two Chicks liquid egg whites and approved. So, I decided to save myself the worry of wondering what to do with leftover egg yolks, and searched the aisles in Sainsburys to purchase some liquid egg whites.
Oh, and I also bought myself a sugar thermometer especially for the task too. That’s one way of tackling the issue of not having a piece of baking equipment.
Ingredients for Strawberry Meringue Buttercream
- 5 large egg whites (I did indeed find and use Two Chicks liquid egg whites)
- 50g caster sugar
- 250g caster sugar
- 100ml water
- 500g unsalted butter, softened
- 1 tbsp strawberry jam
- 1tsp vanilla extract
Top tip: This is much easier to do with a stand mixer. K-mix, Kitchenaid’s were made for these jobs. As a non-owner, I borrowed my friend’s Kenwood, I have much K-envy. So, if you have one, please make this just so that I know that they are being utilised for what they were created for!
1. Whisk the egg whites in a big bowl until they are soft peaks (foamy but don’t hold their shape). Keep whisking, this time adding in 50g of sugar, a spoonful at a time. Continue whisking until they form firm peaks (they don’t lost their shape when you take the whisk out).
2. Leave to one side. In a small saucepan, gently heat up the water and the 250g caster sugar so that the caster sugar melts into a syrup. Once the sugar has melted, put the heat up to full and boil it up th 121C.
Ruth said that it would take 10 minutes. I took about 20 minutes, but wondering whether I either have a faulty thermometer or did something wrong. Anyway, 20 minutes later, it had almost reached 118C and I decided that was good enough for me. Didn’t seem to affect it too much this time.
3. Start whisking the egg whites again at a low speed. Slowly, slowly pour in the sugar syrup into the egg whites. Keep whisking for another 8-10 minutes, until the meringue mixture cools. I had a break at this point to allow the bowl to cool down a bit.
4. When the bowl is cool to touch, it’s time to add the butter. This is a slow process and be patient with it. Basically you have to add the butter to the egg whites in small pieces. If you have a mixer – keep it on the whisk attachment. I didn’t weigh this out, but I estimate that I pretty much added between 10-20g each time. Let one piece of butter be incorporated fully, before adding the next. The mixture does look like it’s going a bit wrong because it becomes liquidy. But don’t worry, that’s normal.
5. Finally(!), when all the butter is added, (if you want/need to, use the paddle attachment on a slow speed to ensure that the butter is all fully mixed in). Then swap in the whisk attachment to whisk the mixture so that it has the consistency and appearance of whipped cream.
7. Fill those piping bags and away we go 🙂
IPHONE FALLS HEADLONG INTO FROSTING
UM! So yes, as I was taking photos, my Iphone slipped out of it’s case and crashed into the decorated cakes. Naturally(!), I ran to grab my camera, so that I could capture a shot of that moment.
Unfortunately, I wasn’t able to interview the said IPhone at the time, and take a shot at what it had to say about all of this because some cupcake had got in the way.
🙂 The salvaged cupcakes!
