White Chocolate Rocky Road with Ginger Nuts

Rocky road bars made from white chocolate, ginger nut biscuits and white Maltesers – I called this “Moon Rocky Road” children’s space themed birthday tea party as it looks like the lunar surface!

May I reassure you? Despite what the media pedals about everyone trying to be a domestic goddess these days, actually most guests are impressed by any culinary efforts no matter how simple.

For my son’s first birthday I served plastic beakers containing strawberries and supermarket mini meringues (the type you get in a tub) drizzled with zig zags of ready made chocolate sauce. My guests were wowed with the simplicity of it and quirky presentation. It made me realise that actually, you don’t have to cook to put together a party proof pudding (as you can witness with my Emergency Trifle from last week).

This rocky road no-bake treat is a step beyond classic chocolate cornflake crispies. The combination of white chocolate with ginger biscuits adds an element of sophistication to impress the grown ups without freaking out the kids.

Melting chocolate for rocky road

An alternative means of melting the chocolate is to use a double boiler or heat proof bowl above a saucepan of simmering water. Make sure the water isn’t touching the base of the bowl if you do it this way.

Microwaving is fast. The double boiler method saves on washing up if you use same bowl to combine ingredients. Choose whichever shortcut suits you!

Under supervision this recipe is easy enough for kids to make too.

My son’s party was space themed, hence the name. I do love funny names for kids’ party dishes.  

Can you think of any other space themed names for popular party food?

White Chocolate Rocky Road With Ginger Nuts

Servings: 12

Equipment

• 8 inch square baking tin lined with baking parchment paper - slightly longer than you need on two sides, to make it easier to lift out.

Ingredients

• 150 g ginger nut biscuits
• 400 g white chocolate broken into squares
• 100 g Maltesers white chocolate version
• 75 g mini marshmallows
• 30 g white chocolate buttons (optional)

Instructions

• Break up the ginger nut biscuits into nubbly pieces - around 2cm.
• Melt the white chocolate, I prefer to do this in a double boiler but you can use a heatproof bowl over simmering water in saucepan. See note re using microwave.
• Lay a rectangle of parchment paper in the baking tin so it is higher on two sides – this means you can lift the rocky road out more easily when it has set.
• Retain a handful of Maltesers to arrange on top. In a mixing bowl, combine the broken biscuits with the molten white chocolate, the remaining white Maltesers, mini marshmallows and chocolate buttons if you are using them.
• Pour into the baking tin, push towards the edges and dot over the last few Maltesers.
• When the chocolate has completely cooled, pop the tin in the fridge to set for at least one hour. When firm, cut into squares to serve.

Notes

Melting white chocolate in the microwave can be risky as the high sugar content means it can scorch and go grainy.

This White Chocolate Rocky Road was inspired by my Smarties Rocky Road.For an alternative Maltesers dessert see my Maltesers Cupcakes. And the biscuits I decorated for the Capture The Flag movie make great Space Themed Cookies.
