Since returning from my travels, I’ve been getting back into the swing of baking slowly – a few cookies to take into the office here, using up an old box of cake mix there – but nothing too extravagant or challenging.
I decided it was time to step it up a notch for my mum’s birthday, with this blueberry mousse cheesecake.
She’s not a cakey-cake sort of person, and definitely prefers fruit desserts to chocolate, so a fruity cheesecake seemed ideal (not to mention that it’s my favourite thing to bake).
I made a sponge base, because I think it’s a nice change to biscuit sometimes, a fairly standard fail-safe new york cheesecake recipe, and then a slightly more troublesome blueberry mousse on top.
I wanted to make the mousse without gelatine because it scares me a little, so decide to try a sort of fake mousse with melted white chocolate and whipped cream, which I’ve used to fill cakes before.
To give it the blueberry flavour and colour, I boiled down a pack of frozen blueberries and strained to make a coulis, then added this in – half into the melted white chocolate and half into the cream, for no reason other than I didn’t know which way would work best.
After pouring the mousse on top of the cheesecake I started to have doubts about whether it would set, so scraped it off, added more melted white chocolate, whipped it up some more and put it back. I really needn’t have done that, as left overnight it would have set up just fine, but lesson learnt I suppose.
I decorated the cake with the leftover blueberry coulis, and it looked rather nice I think.
My mum liked it, and even had a second slice for breakfast, and my dad and step dad seemed to like it too. I’d like to have another go and make a raspberry one to perfect the mousse, and I think you could come up with some great combinations if you changed up the flavour of the cheesecake as well.
Note – I made a 6″ cake because there were only going to be four of us eating it, but you could totally double up to make a 9″ one and the method would be exactly the same.
Blueberry Mousse Cheesecake
For the base:
- 50g butter
- 50g caster sugar
- 1 egg
- 40g self raising flour
- 10g desiccated coconut
For the cheesecake:
- 300g cream cheese
- 100g caster sugar
- zest and juice of 1 lemon
- 1 tsp vanilla extract
- 2 eggs
- 75ml creme fraiche
For the mousse:
- 300g frozen blueberries
- 150g white chocolate
- 150ml whipping cream
To make the base, beat all the ingredients together until smooth then pour into a greased and lined 6″ round tin. Bake at 180 degrees for 20 minutes, or until risen and golden. Leave to cool in the tin, then remove and level the top – you only want the sponge to be about 1cm thick.
For the cheesecake, beat the cream cheese to soften then add the sugar and lemon zest and beat to combine. Add the lemon juice and vanilla and beat; then the eggs and beat; then finally the creme fraiche. And beat.
Put the sponge back in the bottom of the tin and pour the cheesecake mixture on top. Bake at 170 degrees for 10 minutes, then reduce the heat to 120 and bake for another hour. I always have a tray on the shelf underneath with about an inch of water in, this creates steam and helps to stop the cheesecake cracking. After baking, leave in the oven to cool, then transfer to the fridge.
To make the mouse, start by heating the blueberries in a saucepan until all the juices have been released and it’s starting to thicken. Blend either in a food processor or with a stick blender, then pass through a sieve to get rid of any lumps.
Melt the white chocolate and leave to come to room temperature. Whisk the cream until it’s lightly whipped. Add a couple of spoonfuls of cream into the chocolate to loosen it, then add the chocolate back into the cream and fold in gently. Add the blueberry coulis a few spoonfuls at a time until you get a good flavour and colour, taking care not to add too much in case the mousse becomes too runny, and remember to keep some back for decoration.
Remove the cooled cheesecake from the tin, then line the tin with cling film and put it back in. This is a thousand times easier to do with a loose bottomed tin so you can keep the cake on that. Pour the mousse on top of the cheesecake and spread level, then leave in the fridge overnight to set.
When you’re ready to serve, gently lift the cake out of the tin, remove the cling film and transfer to a serving plate. Drizzle the remaining coulis on top and make it look all pretty, then you’re done!
