1. Add 200g of powdered sugar to 1 egg white, and use a manual whisk to make a hard frosting (the frosting will not drip when the whisk is lifted)
2. Take part of the icing sugar and put them into 4 containers, add yellow, black, brown and red pigments and mix thoroughly, and put them in a piping bag for later use
3. Add a little water to the remaining icing sugar, whipped into wet icing (lift the egg beater, the icing slowly drips and disappears in the basin and the icing time in the basin is about 6 seconds), and put it into a piping bag
4. Use white icing to outline irregular contours on the biscuits, then spread white icing in the middle, and put marshmallows
5. Draw a snowman with colored icing and let it stand to solidify
6. The marshmallow snowman biscuits are ready~ Come and try it
