What You Need

My easy Corn Flake Slice recipe is made using just 7 basic ingredients (...and you might just already have them at home!)

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method

Corn Flakes - you can use Kellogg's branded Corn Flakes or any generic brand for this recipe.
Rolled oats - you can use either regular old fashioned rolled oats or quick oats for this recipe. I like to use rolled oats as they give the slice a yummy chewy texture.
Desiccated coconut - this is fine, dried coconut.
Caster sugar - also known as superfine sugar, this variety of sugar is perfect for baking as it dissolves easily.
Butter - use salted or unsalted butter. For a dairy-free alternative, substitute the butter for Nuttelex or a similar dairy-free spread.
Honey - use regular honey or substitute for rice malt syrup, corn syrup or golden syrup.
White chocolate (optional) - for drizzling over the top of the slice.

Equipment Required

This simple Honey Cornflake Slice is made using just a few basic kitchen equipment items.

You will need:

Microwave (or alternatively a stove-top or Thermomix) - for melting the butter and honey.
Large mixing bowl & spoon - for mixing the ingredients.
Baking tin - a rectangular 18cm x 28cm (7 x 11 inch) baking tin.
Greaseproof baking paper - for lining the tin.
Oven - I specify fan-forced oven temperatures. If using a conventional oven, increase the temperature by 10 degrees.

Expert Tips

Prepare the baking tin - ensure that you grease and then line a 18cm x 28cm (7 x 11 inch) baking tin with baking paper. The baking paper should overlap the sides of the tin to allow for easy removal of the slice for cutting.
Honey substitute - you can substitute the honey for rice malt syrup, corn syrup or golden syrup.
Cutting the slice - remove the chilled slice from the fridge. Using a large flat, sharp knife, cut the slice into small pieces.
Storing - store the slice in an airtight container in the fridge for up to 1 week - this will keep the slice extra crunchy!
Freezing - freeze the slice in an airtight container in for up to 3 months. Allow to defrost before consuming.
