Classic Rice Krispie Treats

Line an 8-inch square pan with baking or parchment paper. In a large mixing bowl, measure out your rice cereal and set aside.

Add butter and marshmallows to a medium saucepan. Place on a low heat. Stir gently while butter and marshmallows melt. Mixture should be creamy and smooth.

Once marshmallows have completely melted, pour over rice cereal and mix straight away. Mixture will be sticky, but keep mixing as best you can, until cereal is completely coated.

Pour mixture into your prepared baking pan. Lightly spray a spatula with oil and use it to gently press down mixture, pushing it into the corners. Wet your fingers with water to smooth over any large gaps or holes. Don’t press down too hard or your treats will be hard.

Leave to set for at least two hours. Then slice into squares to serve. Rice Krispie Treats are best eaten on the day they are made. Store at room temperature in an airtight container.
