Combine the oats and dried fruits in a bowl. It will need to be a bowl that can withstand a bit of heat. I usually use a pyrex jug, but I think the husband has ‘put it away’ and I can’t find it in my kitchen.
In a saucepan, melt the butter, honey and peanut butter together. I didn’t have crunchy peanut butter- because I had eaten it all…. and used the smooth. It works, but it is not as good. Boil the mixture, don’t be tempted to taste it…. I usually can’t resist and then regret it.
Then pour all the runny mixture into the dry ingredients. Mix it all in. You will get a really solid mix. Using a dessert spoon, spoon into the T-Bar thing. You won’t need to oil it or whatever because the butter kinda helps it all slide back out. Keep packing it all in. Use the plunger to force it solidly into place.
When it’s all crammed in there, place on the lid and refrigerate overnight.
In the morning, pop them out. I use a plastic knife just to release them around the sides and I run hot water over the bottom of the container, but they come out easily enough.
Store in the fridge in the carry containers, and just throw in the bag/lunchbox.
My tip- if you are likely to lose the carry cases, just wrap in gladwrap… they are expensive cases. I like the idea of knowing EXACTLY what is in these things, and not having any added salt. They are rather messy to make, but easily sorted with a dishwasher. They store and carry well, so that is a bonus.
