Preheat your oven to 160C Fan / 180C and prepare an 8x8-inch square tin.

Crush your cornflakes so they are a little more broken down. You can do this by putting them in a bag and hitting with a rolling pin. You don't want them to be complete dust but if they are crushed a little it helps the bars stick together.

Mix together your maple syrup and peanut butter in a large bowl. If your peanut butter is quite stiff, I recommend heating it briefly to make it more smooth first, otherwise you will struggle with the next step.

Add in your cornflakes, peanut butter and maple syrup, then stir so that the cornflakes are nicely coated.

If you are adding chocolate chips, mix them in now.

Press your mixture into your tin so its nicely compact. Bake for about 15 minutes.

Remove from the oven and allow to briefly cool in the tin whilst you melt your chocolate for the topping. I do this in short bursts of 15 seconds in the microwave, stirring inbetween each burst.

Pour your melted chocolate over the top of your bars and leave to set in the fridge or at room temp until completely set.

Cut into squares and enjoy!
