I have made the kremelta ones and thought they were yuck! (bear in mind Im not the best cook in the world so it could have been due to bakers error

)
My mum used to make rice bubble biscuits with a honey sort of mixture. it had like honey, butter and something else in it and they were yummy. Ill see if I have a copy of the recipe.
A freind of mine's mum used to make the same sort of thing but melt mars bars into them. Perhaps google it!
