1. Melt the butter, peanut butter and honey in a large saucepan (this is where you will mix every thing so best to keep it big, especially if you are doubling it).
2. Add the rice bubbles, rolled oats, wheat biscuits, coconut, apricots, sesame seeds, and sunflower seeds. (and chocolate chips).
3. Mix it all together and press into a large greased tin.
4. Refrigerate (to make it easier, you could cut it into squares before putting it into the fridge).
