Daring Bakers July 2010: Chocolate, Raspberry & Hazelnut Swiss Roll Ice Cream Cake

The July 2010 Daring Bakers’ challenge was hosted by Sunita of Sunita’s world – life and food. Sunita challenged everyone to make an ice-cream filled Swiss roll that’s then used to make a bombe with hot fudge. Her recipe is based on an ice cream cake recipe from Taste of Home.

Just reading about this challenge bought a smile to my face. Here was a dessert that I had been meaning to attempt for ages but had been putting off in favour of some easier desserts. As it was this month’s challenge, I knew it was time to take the whisk by the handle and get baking.

When reading the recipe I felt a little uneasy as it consisted of so many components. We had to make a Swiss roll filled with cream and frozen, two different flavours of ice cream, layered inside the Swiss roll slices and around a hidden fudge centre – yikes!

I was most nervous about the ice cream components as I don’t have an ice cream maker and have tried making ice cream by the home freezing, stirring, freezing process before with limited success. However, I soon discovered that this recipe didn’t require the egg based ice cream variety, but relied on freezing flavoured cream to produce the ice cream which is much better behaved for home freezers.

We were provided with recipes for chocolate Swiss roll, chocolate and vanilla ice creams and a chocolate fudge centre, all of which had to be made from scratch. However, we were allowed to choose our own flavour combinations which was great as I love coming up with different flavour combinations.

I decided to stick with the chocolate Swiss roll as the outside layer, as I loved the colour contrast between the chocolate sponge and the white cream filling. My first ice cream flavour choice was raspberry as I have recently found a bottle of pure raspberry syrup which is so intensely raspberry that I knew it would go wonderfully with the chocolate.

To complement both the chocolate and raspberry flavours I decided to make my second ice cream hazelnut. I achieved this by added chopped roasted hazelnuts to a vanilla ice cream base. I also stirred in some Frangelico (an amazing hazelnut liqueur). The resulting ice cream was divine! Silky smooth and creamy, unsurprisingly due to the cream but with the slight crunch from the nibs of toasted hazelnut and the liqueur flooded your senses with hazelnut flavour – just gorgeous. The main thing to take note of is that by adding the alcohol, the ice cream will not set completely solid, which is great for eating but rather tricky when trying to layer it into a dessert!

Finally I stuck with the chocolate fudge centre as both my ice creams where quite pale in colour and I wanted the hidden centre to really stand out and add a wow factor when the finished cake was cut into. The fudgy sauce itself was delicious, so thick and glossy, I bet it would be great drizzled warm over profiteroles.

Making all the components and assembling the cake took time, especially the hourly mixings of the ice creams while they were freezing, but none of it was too tricky and I was able to complete the dish from start to finish in one day. I had plenty of time to get on with my other jobs in-between and the results were definitely worth the effort.

The dessert looked yummy when I unmolded it. The swirls of Swiss roll making it look quite elegant with little streaks of the pink raspberry ice cream peeking out between the gaps. I cut into it using a knife, unsure what to expect but the results were far better than I had hoped!

WOW! I loved how it turned out. The Swiss roll outer layer gave the edge a two toned stripy effect that reminded me of a zebra. Just inside this was the pale pink raspberry ice cream with the paler nutty hazelnut ice cream at the base. The centre of chocolate fudge came out perfectly formed – I’ve no idea how that happened as it sort of sunk into the ice cream when I added it. Magic! I loved how it really stood out against the ice cream layers and yet tied in with the chocolate sponge edge. It really added a wow factor.

How did it taste? Only one word needed – Divine! Silky smooth and creamy, fruity and nutty with the occasionally crunch texture from the chopped hazelnuts. The Swiss roll had stayed surprisingly soft and the fudge centre was rich and sticky.

Yes it is completely cream and calorie laden but for a dessert this good I don’t care! Just what you need on a hot summer day and it’s sure to impress any guests you might have over for a BBQ. Thanks Sunita for choosing such a fabulous dessert. Click to see the Daring Bakers blogroll.

Chocolate, Raspberry & Hazelnut Swiss Roll Ice Cream Cake
(Inspired by the recipe of the same name from the Taste of Home website)

Chocolate Swiss Roll
3 eggs
110g caster sugar
25g plain flour
20g natural unsweetened cocoa powder
15ml boiling water
A little oil for brushing the pans
For the filling-
250ml whipping cream
½ tsp vanilla extract
30g icing sugar

Method
Preheat the oven to 200C. Brush a Swiss roll tin (11x9 inches) with a little oil and line with greaseproof baking paper.
In a large mixing bowl, add the eggs and sugar and beat till very thick, about 10 minutes. When the beaters are lifted, it should leave a trail on the surface.
Mix the flour and cocoa powder together and sift it over the whisked egg mixture, in three batches and fold in gently with a spatula, making sure to reach down to the base and around the sides. Finally fold in the hot water.
Spread the mixture into the baking pans and spread it out evenly.
Bake for about 10-12 minutes or till the centre is springy to the touch. It will still be quite soft and squishy due to the nature of the cake.
Spread a tea towel on the counter and sprinkle a little caster sugar over it. Flip the cake out of the pan and onto the tea towel. Carefully peel off the greaseproof paper and leave the cake to cool.
Starting from one of the longer sides, start to make a roll with the towel rolled inside. Leave until cool.

To make the Filling
In a large bowl, add the cream, vanilla and icing sugar. Beat until quite thick.
Unroll the cake from the tea towel and spread it evenly with the cream, leaving a ½ inch border around the edge to allow for spreading when re-rolled.
Roll the cake up again, using the towel to help you but don’t roll the towel into the sponge. Transfer the roll to a sheet of clingfilm and wrap it up well. Transfer the roll to a plate or tray and place in the fridge to chill until firm.

Raspberry Ice Cream

300ml whipping cream
½ tsp vanilla extract
55g caster sugar
3 tbsp raspberry syrup/coulis

Method
In a mixing bowl, add the cream, vanilla and sugar mixture and whisk lightly till everything is blended together. Add the raspberry syrup or coulis and mix in well.
Pour into a freezer friendly container (I used a small tupperware box) and freeze till firm around the edges, about an hour. Remove from the freezer, mix well so it all becomes incorporated and smooth. Return to the freezer for a further hour before repeating the process. It may need a third hour depending on your freezer and container used. (You could use an ice cream maker if you are lucky enough to have one).

Hazelnut Ice Cream

250ml whipping cream
30g caster sugar
1½ tbsp Frangelico (hazelnut liqueur)
25g roasted hazelnuts

Method
Chop the roasted hazelnuts until quite fine. Place the cream, sugar and Frangelico into a large bowl and beat until slightly thick. Add the chopped hazelnuts and fold in to mix.
Pour the mixture into another freezable container or ice cream maker. Freeze for an hour, stir it together again and freeze for another hour. Repeat until the mixture is very thick and nearly solid. (The added alcohol will prevent it from freezing completely solid)

Chocolate Fudge Sauce Centre

50g caster sugar
10g natural unsweetened cocoa powder
1 tbsp cornflour
170ml water
7g butter
½ tsp vanilla extract

Method
In a small saucepan, whisk together the sugar, cocoa powder and cornflour until no lumps are visible. Slowly whisk in the water until combined and to prevent lumps from forming.
Place the pan over the heat and stir constantly until it begins to thicken, about 2 minutes.
Remove from heat, beat in the butter and vanilla and set aside to cool.

Assembly

Line a pudding basin or deep bowl with a large sheet of clingfilm.
Cut the Swiss roll into 10-12 equal slices, approximately 2cms each. Arrange two slices at the bottom of the bowl, with their seam sides facing each other. Arrange the Swiss roll slices up the sides of the bowl, right to the top. Cover the bowl with clingfilm and freeze until the slices are firm, about 30 minutes.
Take your nearly frozen raspberry ice cream out of the freezer and spread it over the base and up the sides of the Swiss roll lined bowl.
Cover the bowl with clingfilm and freeze until firm, about 1 hour.
Once set, add the cooled fudge sauce over the raspberry ice cream, in the base only, not up the sides. Return to the freezer for another hour.
Soften the hazelnut ice cream (if needed) and spread it over the fudge sauce, filling the bowl completely to the top in line with the top of the Swiss roll slices. Cover with clingfilm and freeze for at least 4-5 hours until completely firm and well set.

To Serve
Remove the bowl from the freezer and place a serving plate on top. Turn it upside down and remove the bowl with the help of the clingfilm. If the bowl does not come away easily, wipe the outsides of the bowl with a kitchen towel dampened with hot water and try again.
Leave the cake for 10 minutes to soften slightly and then cut slices using a sharp knife, warmed by dipping it in hot water first.
Eat and enjoy. Serves 6-8
