Mary Berry's got a cracking selection of cheesecake recipes, including a scrummy baked berry number, reports the Express.
For the cheesecake bit, lob the butter, sugar, cheese, flour, lemon zest, juice, and egg yolks into a big bowl and beat it until it's silky smooth.
Gently fold the lightly whipped double cream into the mixture using a spatula, then whisk the egg whites until they're stiff and fold them into the mix.
The recipe notes rave: "Blueberries and raspberries make a colourful topping for Mary Berry's classic baked cheesecake.".
Bake it in a preheated oven for about an hour, then switch off the oven and let it cool inside for another hour.
