How can kids help to make chocolate biscuit cake?

This is a really easy no bake recipe that kids can get involved in making. There’s a little bit of heat involved when you melt the chocolate so that’s perhaps a step better for older children but otherwise your kids should be able to do everything.

Kids can help to measure out the ingredients and mix them together. They can also get their hands busy and break the biscuits up into pieces. That’s a fun job that even very young children can do.

Your kids can also help to add the biscuit cake mixture into the cake tin before pressing it down well.

Finally, your kids can help make the ganache. Adding the warm cream to chocolate pieces and stirring it together until it melts is a fun easy job. As is pouring the ganache over the biscuit cake to decorate it.

How long does the chocolate biscuit cake keep?

The biscuit cake will keep for a few days in an air tight container. If it’s very warm you might want to keep it in the fridge.

What sort of chocolate should I use?

This biscuit cake needs a dark chocolate not milk chocolate. Use the best one you can get because you’ll appreciate it when you eat it.

You can check the cocoa content of the chocolate – the higher the %, the more bitter and less sweet it will be. Our favourite plain chocolate for baking is Bournville.

How to make chocolate biscuit cake

Prepare the cake tin

Get your kids to grease then line the base and sides of a 15cm spring-form cake tin with baking or parchment paper.

Break the biscuits into pieces

Measure out the biscuits and get your kids to break them into pieces about 1-2cm big. You’re probably best doing this by hand rather than crushing them with something heavy like a rolling pin as you want them to stay quite chunky and don’t want too many crumbs.

Pop them in a bowl and set them aside for now.

Cream the butter and sugar together

Measure the sugar out and add that to the bowl of a free-standing mixer, or a large mixing bowl. The butter needs to be soft enough to mix in, so if yours isn’t, cut it into a few pieces and pop it in the microwave for a few seconds to soften it, but not so long that it starts to melt.

Beat the butter and sugar together with the k-paddle of your free-standing mixer or a hand held mixer until they are light and fluffy.

Melt the chocolate

Break the chocolate into pieces and add it to a heatproof bowl. Set the bowl over a pan of simmering water (a double boiler) and heat the chocolate gently until it has melted.

Add the melted chocolate to the butter and sugar mixture and stir it in until it is well mixed through.

Add the biscuit pieces

Add the biscuit pieces along, with two tablespoons of water, to the chocolate mixture and stir them through until they are all coated in the chocolate mixture.

Make the biscuit cake

Get your kids to pour or spoon the biscuit mixture into your prepared cake tin.

Using the back of a spoon or a spatula press it down and into the edges of the tin firmly.

Pop the biscuit cake into the fridge to chill for at least half an hour.

Make the ganache

Break the chocolate into pieces or cut it up and add it to a bowl.The ganache will be a little bit easier to make if the pieces of chocolate aren’t too big.

Heat the cream, then once it starts to simmer pour it over the chocolate pieces. Stir it through until the chocolate has melted and the ganache is nice and smooth.

Gently remove the biscuit cake from the tin and set it on a wire rack with some kind of tray underneath.

Pour or spoon the ganache on to the top of the biscuit cake so that it covers the top and the sides.

Leave the ganache to set, add some decoration if you like, serve and enjoy.
