Chocolate Easter Egg Tart

Because too much chocolate is never enough, we’ve created this stunning Easter Egg Tart. We’ve decorated ours with handmade Easter eggs from Tassie’s own The Cat’s Tongue Chocolatiers but you can top with whichever eggs you prefer.

How do I make it?
For the pastry, sift the flour, cocoa powder, icing sugar and a pinch of salt into a food processor. Add the butter and whizz until the mixture looks like fine breadcrumbs. Beat the egg yolk briefly with the water. Add to the food processor and whizz until the mixture starts to stick together. Turn out onto a lightly floured surface and knead briefly until smooth. Shape into a flat disc, wrap in cling film, then chill in the fridge for 15 minutes.
Remove the pastry from the fridge and roll it out thinly on a flour-dusted surface. Use it to line a greased 25cm x 4cm deep, loose-bottomed tart tin. Trim the pastry edges, then chill in the fridge for 20 minutes.
Put a baking tray onto the middle shelf of the oven and preheat to 200°C. Line the pastry case with a sheet of crumpled baking paper and a layer of baking beans or rice, then blind bake on the preheated baking tray for 15 minutes. Remove the paper and beans/rice and blind bake for 5 more minutes. Remove from the oven and leave to cool and crisp. Turn the oven down to 170°C.
For the filling, put the milk, cream and sugar into a pan and slowly bring to the boil, stirring gently. Take off the heat, add the chocolate squares and stir until smooth. Cool slightly, add the eggs and vanilla extract, then mix together well.
Pour filling into pastry case and then carefully slide the tart back onto the baking tray in the oven. Cook for 20-30 minutes or until the filling is cooked but still slightly wobbly. It will continue firming up as it cools. Remove and leave to cool somewhere cold (but not in the fridge) until set. Decorate the top with a generous dusting of cocoa and the mini Easter eggs. Serve cut into thin slices.
