You only need 5 ingredients for these s'mores inspired cornflake bars, perfect for bonfire night.
Preheat your oven grill. Start by melting the butter in a large pan over medium heat. Once it starts to foam, keep stirring and cook until little brown specs appear all over the butter and it smells nutty and toffee like. Remove from the heat
Arrange the marshmallows all over the baking sheet, and pop under the grill until puffed and browned, just a few minutes.
Add into the brown butter, and mix until combined. It'll take a few minutes to fully incorporate.
Add the cornflakes, mix through really well, then place into a square tin lined with greaseproof paper. Press down. Chill in the fridge for at least 1 hour.
Melt your chocolate in the microwave or over a double boiler. If you want the chocolate extra glossy, you can add some coconut oil, but this is optional.
Slice up the cornflake bar however you like, I went for 9 pieces. Dunk a corner in the dark chocolate, place on a wire rack, then sprinkle with flaky salt. Pop back into the fridge until the chocolate is set, and enjoy!
