Bake James Martin’s crunchy cornflake and marshmallow cookies for a delicious treat with a cup of tea


1. For the cornflake mixture: preheat the oven to 180C/160C fan/gas 4. In a bowl, combine the cornflake mixture with a pinch of salt and spread out evenly on a baking tray. Bake for 6-8 minutes then allow to cool.

2. For the cookie mixture: increase the oven temperature to 200C/180C fan/gas 6. Cream together the sugars, egg, vanilla and melted butter. In a separate bowl, add the bicarbonate of soda and 1 teaspoon salt to the flour then stir and add to the rest of the mixture.

3. When the mixture is combined to a smooth paste, mix in the chocolate chips and cooled down cornflake mixture.

4. Roll the dough into small 30g balls and place onto a lined baking sheet. Allow plenty of space between each ball as they will spread out in the oven.

I cooked these yesterday and was very disappointed with them, they were so greasy. I have a family of all men and they normally tuck into all my cooking but even they turned up their noses at these, the whole lot ended up in the bin, such a waste of ingredients.
