Make a crumble out of the flour, almonds, butter and sugar. Place ¼ of the crumble aside, to sprinkle on the top. Add the egg to the remaining dough and make shortcake. Put the dough into the fridge for about 1 hour. Roll out the dough and put it into a round baking tray with a diameter of 22 cm. Bake the bottom of the tart for approx. 15 minutes at 190 degrees.
Peel the apples, remove the cores and cut into thin half-slices, mix with the lemon juice and place on the baked base of the tart. Cover with the Lauretta vanilla flavoured filling and sprinkle with crumble.
