First put the oven onto gas marks 4 or 180 oC

Next grease a square baking tin ready for later.

Then melt the margarine in a large saucepan.

After all the margarine is melted remove the heat and add the ingredients in stir well with a wooden spoon.

Put the mixture into the greased tin and press down evenly along the tin to make flat.

With your oven gloves put the tin in the oven on the middle shelf for 1/2 an hour or (until the oat crunch is slightly brown round the edges.)

Take out the tin from the oven and wait for it to cool before you cut. When it is ready cut the oat crunch in square equal pieces.

And enjoy your oat crunch :)
