When spreading frozen yoghurt over cake, spread it to within 2.5cm of edges. This prevents the filling from seeping out of the finished roll.
Beginning with a short edge, roll the filled cake up, Swiss-roll-style. Wrap the roll in greaseproof paper, place in freezer until firm, at least 2 hours.
Sink your spoon into this warm crumble. A quick to fix crunchy topping over a sweet fruit filling results in pure magic.
Crunchy on the outside and marshmallowy within, this melt-in-the-mouth meringue topped with luscious fruit is irrestible.
