Energy bars are expensive, and generally not full of anything special. I also live miles from anywhere so its useful to be able to rustle some up out of store cupboard ingredients. You need:
240grams of peanut butter
240 grams of clear honey
175 grams of sugar-free mueseli
200 grams dried fruit (I use 50 grams each of pineapple, apricot, raisins & sultanas)
100 grams of seed mix, chopped nuts etc
Put the honey and peanut butter into a saucepan and slowly melt it together over a low heat. Simply chuck in the muesli and stir, and then stir in the other ingredients until fully mixed.
Grease a baking tin, and pour the mix into it, flattening it down. Put in the oven on 200ºC for about 12 minutes. They should go golden brown but still be fairly soft.
When you bring them about, score with a spatula and allow to cool, when it will harden. Then you can take it out the tin, and break it into pieces along the score lines.
