Preheat the oven to 180C/gas4/ fan 160C. Line the base of a loose-bottomed 23cm cake tin with greaseproof paper and butter the sides.
Mix almonds, butter, sugar, flour, cinnamon, egg and egg yolk in a food processor just until the ingredients are evenly combined.
Spread half the mixture over the base of the tin in a smooth layer with no gaps – easiest to do this with two forks. Lay the sliced strawberries on top. Add the remaining cake mixture and spread it as best you can, but don’t worry if a few strawberries peep through.
Bake for 1 hour (it may need an extra 5 minutes), but check after 40 minutes – if it is getting too brown, cover loosely with foil. The torte should be slightly risen and dark golden brown when cooked.
Cool in the tin slightly, then loosen the edges with a knife and remove from the tin. Slide the torte onto a plate and sprinkle with a dusting of icing sugar. Serve warm or cold, in wedges with dollops of cream and Greek yogurt.
