By themselves, Rice Krispies do not hold together or form shapes. The addition of marshmallow binds this project together, allowing you to form or cut almost any shape desired. Some simple forms to start out with would be a layered cake, geometrical shapes, Easter eggs, hearts for Valentine's Day, Christmas trees or miniature bird nests. Follow the steps below to learn how to sculpt with Rice Krispies.
Make the recipe for Rice Krispies treats by melting 3 tbsp butter in a large saucepan over low heat. Add an entire package of marshmallows and stir constantly until the marshmallows are melted. Remove the saucepan from over the heat and add 6 cups of Rice Krispies cereal. Stir quickly until the cereal is coated with the marshmallow mixture.
Spray your hands with cooking spray so that the Rice Krispies mixture does not stick to your hands while you are working with it.
Form the basic shapes of your sculpture quickly. You will need to work quickly because the longer the recipe cools the less pliable it will become. You will have opportunity to refine the project once it cools. For example, to make a miniature bird's nest, quickly form a loose ball and press down to half it's height, using a round object such as the bottom of a small cup to make the impression in the centre of the nest at the same time. To create one larger piece, pour the entire contents of the recipe into a bowl or storage container that has been sprayed with cooking oil, press down and allow it to cool. Once it has cooled you can use tools to sculpt your finished work.
Use some basic kitchen equipment to form your finished shape. Cookie cutters, bowls and cups allow you to cut precise shapes, similar to using a cookie cutter. Serrated knives are effective tools for carving details into your finished project. Spray all tools with cooking spray, prior to use, to avoid sticking.
Finish your project with a few added touches to transform your sculpture from a conglomeration of cereal and marshmallow into an edible work of art. Use melted chocolate to dip accent pieces. Spray with coloured frosting to add detail and colour. Add strategically placed candy and sprinkles for colour and texture.
If you are making a large sculpture it is best to make your Rice Krispies treat recipe in batches as opposed to one large batch. This will allow you to work with a smaller amount at one time and prevent your recipe from cooling too fast. It is not recommended to use diet or reduced calorie butter or margarine; the texture will be adversely affected.
If you have small children helping, it is best for you to do the preliminary moulding while the mixture is the hottest, and allow the young helpers to assist with the finishing touches, such as dipping in chocolate and decorating.
