- Grease and line the base of a 20cm loose-bottomed cake tin with baking parchment.
- To make the base, add the chestnuts, almond flour, cacao powder, almond butter, maple syrup, coconut oil, orange zest, spices and a pinch of salt to a food processor. Blitz until the mixture resembles wet sand.
- Press the mixture firmly over the base and up the sides of the prepared tin. Spread the pistachio butter evenly over the base, then freeze for 30 minutes.
- Meanwhile, gently warm the coconut cream in a saucepan until melted but not boiling. Place the chopped chocolate in a heatproof bowl, pour over the warm coconut cream and leave to stand for 5 minutes. Whisk until smooth, then stir in the maple syrup.
- Pour the chocolate filling over the pistachio layer, gently tapping the tin to remove any air bubbles. Scatter over the crushed mini eggs and pistachios.
- Chill in the fridge for 4-6 hours, or overnight, until set.
- Carefully remove the tart from the tin, decorate with extra mini eggs if you like, then slice and serve.
