What comes out is a thick batter that looks like this. [Have a another bowl containing a pre-made batch of batter to show your audience.] Have the child carefully stir it with a wooden spoon. The ingredients will be slightly hot at first. If you decide to use nuts, you would add them at this time. Once the ingredients are all fully combined, spread the batter in the baking pan. [Do this step with the pre-made batter.] Freeze the fudge for one hour or until it’s firm. After it hardens, it can be easily cut into squares.
