Mini peanut butter Oreo cups

Whizz the peanuts in a food processor until finely chopped. Put in a large bowl. Whizz the biscuits to coarse crumbs; add to the nuts.

Melt the butter, 100g milk chocolate and 50g dark chocolate together in a microwave (or a heatproof bowl set over a pan of barely simmering water). Stir through the nut and biscuit mixture until evenly coated. Divide between 2 x 12-hole silicone mini muffin moulds (or use mini muffin cases in mini muffin tins), pressing each down with the back of a teaspoon to level. Spoon 1 tsp peanut butter on top of each.

Melt the coconut oil with another 75g milk chocolate and remaining 300g dark chocolate. Transfer to a jug and carefully pour into each mould (or case), filling just to the top of the mould.

Put the remaining 25g milk chocolate in a small piping (or resealable) bag. Put in a bowl, cover with just-boiled water and set aside until melted. Remove from the water, snip off the tip and pipe zigzags over each peanut butter cup. Sprinkle each with a little bronze crunch, then chill in the fridge for at least 4 hours, until solid. Remove the cups from the moulds (or keep in the cases) and pop into gift boxes. Store in the fridge for up to a week, but they are best eaten at room temperature.
