Vanilla is a flavour that is quite often overlooked, overshadowed by it’s bigger, bolder brother chocolate, it is most often used to enhance other ingredients rather than allowed to shine on it’s own. But when used well, vanilla is a beautiful stand-alone flavour, sweet, complex and comforting. I decided to bake a cake flavoured only with vanilla to highlight just how delicious it can be.
I added (a generous amount of) vanilla to both the cake and buttercream; the cake is a fairly simple sponge, made using the reverse creaming method which makes for an extremely moist, melt in the mouth crumb. The icing is ermine buttercream, also known as cooked flour frosting, which is one of my absolute favourite buttercreams; it is positively ethereally light and fluffy, almost mousse like, and is incredibly easy to spread and pipe. It sounds like an odd way to make icing – cooking milk and flour and then beating it into butter and sugar, but it really works and is so much nicer than the standard butter and icing sugar frosting, and is also easier and less temperamental than swiss meringue buttercream.
The cake stayed soft and moist for nearly a week when kept in an airtight container at room temperature. Very vanilla cake is the ideal cake for any celebration as it can be enjoyed by everyone, young and old; the flavour is simple enough for children, yet it is anything but boring. The texture is smooth, light and fluffy, the silky buttercream is flecked with vanilla bean seeds, hinting at the flavour. I enjoyed it with a scoop of vanilla ice cream for an all out vanilla experience, but it is also lovely dressed up with some strawberries for the perfect Summer cake.
- 4 large egg whites (about 120g)
- 210ml (3/4 + ⅛ cup) full fat milk
- 2½ tsp vanilla bean paste
- 240g (2 cups) plain flour
- 25g (scant ¼ cup) cornflour (cornstarch)
- 265g (1 + ⅓ cups) caster sugar
- 17g (1 slightly rounded tbsp) baking powder
- ½ tsp salt
- 150g (1/2 cup + 2tbsp) unsalted butter, softened
- 200ml (3/4 cup + 1tbsp + 1tsp) full fat milk
- 4 tbsp plain flour
- 175g (3/4 cup) unsalted butter, softened
- 175g (3/4 cup + 2 tbsp) caster (superfine) sugar
- 1½ tsp vanilla bean paste
- pinch salt
- Preheat the oven to 180C/350F/gas mark 4. Grease three 15cm/6in round cake tins and line with baking parchment.
- Mix together the egg whites, 80ml (1/3 cup) of the milk and the vanilla bean paste in a jug. Place the flour, cornflour, sugar, baking powder and salt in a large bowl or the bowl of your stand mixer and mix briefly to combine.
- Add the butter and the remaining 130ml of the milk and mix on low (with your stand mixer or an electric whisk) until moistened, turn the mixer up to medium and beat for about a minute and a half until smooth. Add the egg white mixture in three separate additions, beating well after each one and scraping down the sides of the bowl occasionally.
- Divide the batter evenly between the three pans and bake for 25-30 minutes until golden and a skewer inserted into the centre comes out clean. Leave to cool in the tins for 15 minutes or so before turning out onto a wire rack to cool completely.
- I find it easiest to ice cakes if they are cold or frozen (less crumbs), so if you like, once the cakes are cold you can put them in the freezer for an hour or two before you ice them; by the time you come to eat the cake they will have defrosted.
- Whisk together the milk and flour in a small pan until smooth. Place over a medium-low heat and whisk constantly until the mixture is very thick and paste-like. Scrape into a bowl, cover with clingfilm directly on the surface and refrigerate until completely cold.
- Once the flour mixture is cold, place the butter and sugar in a large bowl or the bowl of your stand mixer and whisk on high speed for a good few minutes until extremely light and fluffy. Whisk in the vanilla and salt.
- Whisk in the flour mixture a tablespoon at a time, whisking well after each addition, until it has all been mixed in and the buttercream is completely smooth, it should almost have the consistency of whipped cream.
- Place one of the cake layers on a cake stand or serving platter, spread a dollop of the buttercream over the top, place another cake layer on top, press down gently and repeat. Place the final cake layer on top and give the whole cake a very thin coating of buttercream, just enough to fill in the gaps. Use a palette knife or dough scraper to get it smooth.
- Place the remaining buttercream in a piping bag fitted with an open star nozzle (or nozzle of your choice) and pipe dollops of it over the top of the cake, starting with a ring around the outer edge and working your way inwards.
- The cake will remain soft for several days if stored in an airtight container at cool room temperature.
