Super-pretty chocolate bark sits atop gooey caramel and a buttery base in this showstopper. Broken down into just seven simple steps, our simple shortbread recipe makes creating this indulgent sweet treat at home really easy. Why not give it a go this Easter?

  1. Make the dough

    Lightly grease and line a 20cm square tin with nonstick baking paper. For the shortbread, use an electric hand whisk to beat 125g unsalted butter and 60g golden caster sugar in a bowl until combined. Add 125g plain flour, 60g rice flour and a pinch of salt and beat again, until it starts to form a dough.

  2. Bake the shortbread

    Tip the dough into the tin. Press it down evenly with the back of a metal spoon. Prick all over with a fork and chill in the fridge for 1 hour to firm up. After 30 minutes, preheat the oven to gas 4, 180°C, fan 160°C. Once firm, bake for 25-30 minutes, or until golden and baked through. Leave to cool completely.

  3. Make the caramel

    To make the caramel, heat 200g caster sugar in a pan set over a medium-high heat. Keeping a close eye on it, let it melt without stirring, swirling the pan around often, so that the sugar melts evenly and doesn’t crystallize. Once a rich caramel colour, remove from the heat and carefully add 125g cubed unsalted butter, 100g light muscovado sugar and 175ml double cream.

  4. Layer it up

    Return to a low heat, and wait for any solidified sugar to melt. Increase the heat slightly and simmer for about 7 minutes, until smooth, thick and golden. Leave to cool for 20 minutes. Pour the caramel onto the shortbread and chill until firm, about 2 hours.

  5. Make the topping

    Break 200g white chocolate into pieces and melt in a heatproof bowl over a pan of simmering water. Divide between 4 bowls. Colour one with a few drops of pink gel food colour, one with blue, one with yellow and one with green. Break 200g of 70% cocoa solids dark chocolate into pieces and melt. Cool slightly then pour over the caramel.

  6. Decorate the topping

    Dot teaspoons of the 4 coloured white chocolates over the surface of the dark chocolate. Use a skewer to gently swirl the colours through the dark chocolate in a continuous motion without lifting the skewer. Top with white chocolate stars. Chill for 5 hours to firm up completely.
