Chocolate swiss roll with coffee buttercream

Here's a second attempt at swiss roll. For easier rolling and to attain a swiss roll with a smoother outer cover, the sponge cake should be rolled up once it is out of the oven before it is left to cool.

The best part of this swiss roll is the coffee buttercream! This coffee-flavoured buttery-sugary concoction has a rich aroma and is absolutely lip-smacking. I could eat it on its own! I was impatient and started coating the mildly warm cake with it, and immediately regretted my decision as I watched the buttercream melt into my chocolate sponge cake. *a dramatic NOooooo...*



Nevertheless, this cake made a delightful elevenses. Enjoy with a cuppa!

Chocolate swiss roll
What?

• Olive oil, for greasing
• 100 g caster sugar, and some extra 
• 2 eggs
• 1 tsp vanilla extract
• 1 tbsp warm water
• 75 g plain flour, sifted
• 25 g cocoa powder, sifted
• Icing sugar, for dusting (optional)

How?

1. Line a swiss roll tin with parchment paper and brush it with olive oil. Dust with some caster sugar.
2. Whisk the eggs and sugar together until it is light and fluffy.
3. Mix in the water and vanilla extract.
4. Mix the cocoa powder and flour together in another bowl. Fold in the flour mixture to the egg batter, one-half each time.
5. Pour the batter onto the prepared tin and bake in a preheated oven at 180 deg C for 15 minutes.
6. Lay a piece of parchment paper on top of a damp tea towel and sprinkle it with caster sugar. Turn the cake onto the sugared parchment paper and peel the parchment paper off the base of the cake.
7. Make an incision (do not cut through!) about 1cm from the edge where you want to start rolling. With another parchment paper placed on the top of the cake, roll the cake up carefully and leave it to cool.
8. Prepare the buttercream (recipe below).
9. When cake has cooled, unroll the cake and spread butter over it, leaving a border at the end (about 1"). 
10. Roll the cake up again. Sprinkle with some icing sugar before serving.

Swiss roll

One fine afternoon, I came home with a strange craving for swiss roll.

Contrary to what the name suggests, this sponge roll cake did not originate from Switzerland. Invented 3 decades ago (believably from Central Europe), this is a popular confection served for elevenses or afternoon tea.

This cake is called differently around the world (for instance, roll cake, jam roll, roulade, tortas) and can be filled with fruit jam, whipped cream, butter cream or even cheese. I think back in SG we would have some filled with kaya, durian or mango.

With the waft of eggy-goodness (this batter has a 鸡蛋卷 smell!) coming from the kitchen, I looked forward eagerly to my freshly-baked tea break.

When the sponge cake was done, I slathered it liberally with strawberry jam, rolled it up and dust it with some powdered sugar. Best enjoyed with a hot beverage!

What?

• Olive oil, for greasing
• 125 g caster sugar, and some extra 
• 3 eggs
• 1 tsp vanilla extract
• 1 tbsp warm water
• 125 g plain flour, sifted
• 150 g strawberry jam
• Icing sugar, for dusting

How?

1. Line a swiss roll tin with parchment paper and brush it with olive oil. Dust with some caster sugar.
2. Whisk the eggs and sugar together until it is light and fluffy.
3. Mix in the water and vanilla extract.
4. Fold in the flour, one-half each time.
5. Pour the batter onto the prepared tin and bake in a preheated oven at 180 deg C for 15 - 20 minutes, or until the top is slightly golden.
6. Lay a piece of parchment paper on top of a damp tea towel and sprinkle it with caster sugar. Turn the cake onto the sugared parchment paper and peel the parchment paper off the base of the cake.
7. When cake has cooled down, make an incision (do not cut through!) about 1cm from the edge where you want to start rolling. Then spread the cake with jam, leaving a border at the end (about 1"). 
8. Start rolling! The incision will help to roll it up easier. Sprinkle with some icing sugar before serving.
