I also prefer DIY desserts. Berries with cream, creme fraiche or yoghurt, DIY gooseberry fool in season, cranberries cooked with orange juice, zest & spices with yoghurt in winter. Blackberry and apple baked with a little cinnamon and butter, with or without a chocolate hazelnut topping... Cream and/or full fat cream cheese whipped up with various additions and flavours - coffee and walnuts, cocoa with orange or peppermint essence, or some toasted chopped hazelnuts, or plain with vanilla, coconut cream with lime and ginger,... DIY low carb cheesecake, shortcake, or muffins with or without various flavourings and additions. e.g. blueberries or above cranberry mix, or as mini coffee & walnut cakes or carrot cakes with pecans and a little grated carrot. Or simply a piece or 2 of high percentage dark choccolate to finishyour meal off with.
Definitely Oppo (currently on offer again at Waitrose), current favourite is the salted caramel - for a special treat with Sukrin gold syrup & salted pecans , and although more expensive you can buy all 4 flavours in mini single portion size tubs too. And although I've not done this: frozen berries and thick cream can be whizzed up for instant fruity ice cream!
Most of them are quick and easy to make just needing a little low carb creativity, and IMO much better low carb wise than shop bought desserts.
