Preheat the oven to 190C/375F/gas mark 5.
On the hob, melt butter and honey together. Add the sugar.
Take off the heat and add the porridge oats, then coconut, then the plain flour last. Don’t put all the flour in if the mixture looks dry – it's there just to help bind it all together and makes for a more squidgy flapjack.
Line a baking tin, whatever shape you like. Press mixture into a depth of about 1 cm.
