Chequerboard wafer cake
Chequerboard wafer cake
375g (2 1/2 cups) plain flour
1/2 tsp baking powder
1/4 tsp bicarbonate of soda
230g unsalted butter, at room temperature
430g (2 cups) caster sugar
6 eggs
1 tbsp vanilla extract
250g sour cream
Pink gel or liquid food colouring, to tint
2 x 175g packet creme wafer minis
buttercream
5 egg whites
270g (1 1/4 cups) caster sugar
340g unsalted butter, chopped, at room temperature
2 tsp vanilla extract
Step 1
Preheat the oven to 160C/140C fan forced. Lightly grease two
7cm deep, 14 x 24cm (base size) loaf pans and line base and sides with baking
paper, allowing the 2 long sides to overhang.
Step 2
Sift the flour, baking powder and bicarb into
a bowl. Use electric beaters to beat the butter and sugar in
a separate bowl until pale and creamy. Add the eggs, 1 at a time, beating
well after each addition. Add the vanilla and beat until combined.
Gently fold the flour mixture into the butter mixture, alternating with
the sour cream, until just combined.
Step 3
Pour half the cake mixture into 1 prepared pan. Smooth the
top. Add a little food colouring to tint the remaining cake mixture
pink then pour into the remaining pan. Smooth the top. Bake for 1 hour 10
minutes or until a skewer inserted into the centre of the cakes comes out
clean. Set aside in the pans for 10 minutes to cool slightly before
transferring to a wire rack to cool completely.
Step 4
To make the buttercream, use a balloon whisk to combine
the egg whites and sugar in a large heatproof bowl. Place
bowl over a saucepan of simmering water (make sure the bowl doesn’t touch the
water). Cook, stirring often with the whisk, for 3-5 minutes or until hot to
the touch (to test, transfer a small amount to a saucer and if mixture is hot,
it is ready). Remove bowl from heat and transfer mixture to a stand mixer with
the whisk attachment (you can also use electric beaters). Whisk on high speed
for 10 minutes or until almost room temperature. Switch to paddle attachment.
Reduce speed to low. Gradually add the butter, beating well after each
addition, until pale and creamy. Add the vanilla and a pinch of salt.
Beat until well combined. Transfer 1 cupful of the buttercream to a piping bag
fitted with a 1cm plain round nozzle.
Step 5
Use a large serrated knife to trim and level the top of each
cake. Cut each cake in half horizontally. Layer alternate slices of pink and
vanilla cake on top of each other, using a little of the buttercream between
each layer to adhere. Use the knife to level the sides of the cake if
necessary. Evenly slice the cake lengthways into four long pieces.
Step 6
To assemble, spread a little buttercream into the centre of
a serving plate or cake board. Lay a slice of cake flat and cover with a little
buttercream. Layer with the remaining cake slices, taking care to alternate the
colours to form a chequerboard and covering each layer with a thin layer of
buttercream. Spread remaining buttercream over the top and sides of cake. Use
an offset palette knife or cake scraper to smooth the sides and top. Pipe peaks
of the reserved buttercream over the top of the cake in rows to cover.
Arrange wafers in a chequerboard pattern over the top of the
buttercream peaks.
