Makes: 10
Prep: 20 minutes
Cook: 25-30 minutes

You will need

• 150g blueberries
• 1 level tablespoon cornflour
• 75g mixed sunflower seeds, pumpkin seeds and sesame seeds 
• 175g porridge oats
• 150g block margarine or butter
• 75g light muscovado sugar
• 2 level tablespoons golden syrup
• 75g wholemeal plain flour

1. Preheat the oven to 180C, Gas Mark 4. Lightly brush the base and sides of a shallow 20cm (8inch) cake tin and line the base with a square of non-stick baking paper the same size.  

2. Put the blueberries in a bowl, sprinkle over the cornflour and gently mix with a spoon until the blueberries are evenly coated. 

3. Add the seeds to a plastic bag, seal the end of the bag then bash with a rolling pin until the larger seeds are crushed. (Or leave them whole if you’d rather.) Scoop out 3 tablespoons and put into a bowl with 3 tablespoons of the oats and save for the topping.  

4. Add the margarine or butter, the sugar and the golden syrup to a saucepan and cook over a low heat for 3-4 minutes, stirring with a wooden spoon until the margarine or butter has melted.

5. Take the saucepan off the heat. Tip the seeds from the plastic bag and the rest of the oats into the pan along with the flour and mix together well. 

6. Spoon about two-thirds of the oat mixture into the paper-lined tin and spread flat with a round-bladed knife. Sprinkle the blueberries on top then dot small spoonfuls of the rest of the oat mix on top to make an even layer with a few of the blueberries still showing. Sprinkle with the saved seeds and oats.

7. Bake for 25-30 minutes until the top is golden brown. Take out of the oven with oven gloves, put on to a wire rack. Press the top down gently with a fish slice then leave to cool in the tin.

8. Loosen the edge of the muesli bars, take out of the tin, peel off the lining paper then cut into 10 bars. Eat some now and put the rest in a plastic container, or wrap individually in foil or clingfilm, keep in the fridge overnight then add to your lunchbox next morning.
