Raspberry jam doughnuts

Use a chunky raspberry jam to fill the doughnuts, or use up a standard jar by mixing it with a handful of crushed fresh raspberries for extra zing.

Chocolate custard doughnuts Melt 100g dark chocolate in a heatproof bowl over a pan of simmering water (or in the microwave in 20-second bursts), then mix with 200g ready-made custard.

Chill for 1-2 hrs to firm up before using.

Crunchy biscuit doughnuts

Fold a handful of crushed chocolate sandwich cookies or caramel biscuits

through lightly whipped cream for a filling that adds texture as well as flavour.
