Wash and thoroughly dry a snowflake soap/chocolate mould and set aside.
In a mixing bowl, mix the almond oil, witch hazel, and essential oils.
In a separate bowl, whisk together the baking soda, citric acid, sea salt, arrowroot powder, beet powder, and spirulina powder. Break up any lumps with your fingers. Slowly add the wet ingredients to the dry ingredients and mix with your hands until the liquid is evenly distributed; it should look like wet sand.
Place 1/4 of the mixture inside each snowflake cavity, pressing down firmly. Transfer the moulds into the freezer for 30 minutes to set. Once frozen, remove from the moulds and allow them to air-dry overnight before packing them up. Place on the shower drain to breathe easier!
