Wrap bars individually in baking parchment or foil so that they are easy to grab in the morning, an energy-boosting snack-to-go at a fraction of the cost of store-bought.
Preheat the oven to 180°C/350°F/Gas 4. Cut a piece of baking parchment a little larger than an 18 x 28 x 4cm/7 x 11 x 1½in rectangular tin or pan, snip into the corners then press the paper into the tin so that the base and sides are lined.
