Think sticky toffee pudding but as cake squares. This healthier version contains high-fibre prunes as well as naturally-sweet dates. Delicious served with a drizzle of dark chocolate on top.
Preheat the oven to 160°C/325°F/Gas 3. Cut a piece of baking parchment a little larger than an 18 x 28 x 4cm/7 x 11 x 1½in rectangular cake tin or pan, snip into the corners then press the paper into the tin so that the base and sides are lined.
