Instagram Cake

For friendly, filtered fun you can’t go past Instagram. Twelve million people use it daily with Instagram photos receiving 8,500 ‘likes’ per second!   But amongst all the happy snaps, I do wonder if we are becoming a generation of socially dissatisfied tourists inspecting the highlight reel of other people’s lives.  One young mum shared with me that she had stopped using Instagram because she was feeling down seeing so many images of friends on holidays and relaxing on the beach, while she was at home changing nappies and cleaning up vomit.

Comparison is a dangerous poison but the good news is, there is an antidote – being thankful for what you’ve got.  To quote my friend who is working with the poor in Cambodia ”Gratitude is a guaranteed ‘make-you-feel-better’ force – a powerful, yet underestimated and under-used attitude.”

So why not find something in your life that you are grateful for, no matter how little it may seem, snap a pic (or a video) and post it to instagram with the #grateful.

Unless you have a blast freezer this instagram dessert needs to be made over a couple of days to allow time to freeze.  The advantage of this type of dessert lies in the fact that you can  make the whole dessert well ahead of time.  On the day that you need it pull it out of the freezer, glaze and garnish it and leave it in the fridge to defrost.

Rainbow Jello
85g (3 ounces) packet of strawberry jello (red)plus 300ml cream
85g (3 ounces) packet of lime jello (green) plus 300ml cream
85g (3 ounces) packet of mango jello (yellow) plus 300ml cream
85g (3 ounces) packet of berry blue jello (blue) plus 300 ml cream
Make each layer seperatley. Mix together the jello and the cream and heat in a saucepan until boiling. Pour the first layer into a rectangular container lined with alfoil. Mine was 12cm (4.72 inches) x 27cm (10.63 inches) and the layers were a bit thick so use a bigger container or do not pour all the mixture in. Either leave that to set and then make your next layer in the same way, leave to cool at room temp and then pour on. Or follow directions on the video to speed up this process. Make sure that when you add a new layer it is not warm or it will melt the layer underneath.
Leave that whole thing in the freezer overnight.

Lens and view finder of instagram cake
Next make your lens and the view finder parts, I used a coke jelly but I really wasn’t happy with it, the coke doesn’t like freezing and defrosting. It separates into a liquid and a weird gel not at all what I was going for. I have since experimented by adding various additives like xanthum gum to it before freezing and they didn’t help. So I would recommend that you skip that and make a cake centre using the chocolate cake recipe, make it flat and then cut circles of cake and line then up to make the cylinder shape that we need. And cut out a long rectangle for the view finder.

Take your deep rectangular container, on some paper draw an instagram logo in the right size, sticky tape that to the outside of the container to give you a guide as to how high up the mousse needs to come. The container that I used was 12cm (4.72 inches) wide x 25cm (9.84 inches) long x 15cm (5.91 inches) tall but the full height was not required.

Take your rainbow jelly out of the freezer and remove it from the dish. If you are having trouble getting it out put it in a sink filled with hot water for 30 seconds, do not let the water get into the dessert. Use a sharp knife to cut a slice from the centre of the jello int he correct size for the coloured part of the logo. Put in place in the contianer and then put it back in the freezer while you make your mousse.

Chocolate Mousse for top of instagram cake
150ml milk
50g (1.76 ounces) cream (pure cream, thickened cream, pouring cream or heavy cream are all good)
1/2 teaspoon vanilla

3 egg yolks
40g (1.41 ounces) 0r 2 1/2 tablespoons sugar
10g (0.35 ounces) or 2tsp cornstarch

14g (0.49 ounces) or 1 tablespoon gelatin
60g (2.12 ounces) or 1/4 cup water

130g (4.59 ounces) milk chocolate
100g (3.53 ounces) dark chocolate

additional 300g (10.58 ounces) of cream

To make your chocolate mousse place the milk, cream and vanilla into a saucepan.
In a seperate bowl put your egg yolks, sugar and cornstarch and whisk until smooth.
In another bowl mix together you water and gelatin and leave the gelatin to bloom or absorb the water.

Heat the cream mixture until it boils, then add it a little at a time into the egg yolk mixture, stirring well after each addition. Once it is all combined then pour it back into the saucepan. Return it to the heat and stir continuously until it thickens, then keep stirring over the heat and let it bubble for at least 30 seconds.
Remove from the heat and stir in your gelatin until it is dissolved. Melt your chocolate, it does not need to be kept in temper just melt it carefully so that you do not burn it and mix it together with the custard. Leave it to cool completely.

Whip the remaining cream and then using a spatula fold the chocolate custard into the cream.

Pour some mousse over the coloured part of the cake making sure it goes right down and into the gap, and in a thin layer on the base. Then cut your cake into a long rectangle for the lens, put into place and and pour over the rest of the mousse making sure it comes up to the level marked on the side of you container. Smooth it out as best as you can. Place that in the freezer.

White Chocolate Mousse for white part of instagram cake
300g (10.58 ounces) milk
100g (3.53 ounces) cream
1 teaspoon vanilla

6 egg yolks
80g (2.82 ounces) 0r 5 tablespoons sugar
20g (0.71 ounces) or 4tsp cornstarch

28g (0.99 ounces) or 2 tablespoon gelatin
120g (4.23 ounces) or 1/2 cup water

260g (9.17 ounces) white chocolate

additional 600g (21.16 ounces) of cream

Make you white chocolate mousse exactly the same way as for your first chocolate mousse but using melted white chocolate instead, note this mousse uses less chocolate that the other one.

Take your frozen dark chocolate mousse and using a spoon or ice cream scoop scrape off a section from the centre down to where the top of the lens is on your instagram picture. Place a small layer of white chocolate mousse down the middle and then add your lense down the centre. Line you cirlces of cake up to make along cylinder pushing them tightly together so the mousse doesn’t go between them. Pour over the rest of the white chocolate mousse. Smooth it out and put the whole thing in the freezer.

Crunchy Chocolate Base
130g (4.59 ounces) milk chocolate
30g (1.06 ounces) unsalted butter
1 cup or rice bubbles or rice krispies

To make your base, melt together the butter and chocolate and mix through some rice bubbles or rice crispies. Spread it evenly over the dessert using the back of a spoon to smooth it out so that you have a flat base. Put this back in the freezer for 15 minutes to let it set.
