To prepare the cream cheese icing: combine 2 ounces dairy-free cream cheese with 1/2 cup powdered sugar and 1 tablespoon plant milk in a bowl. Whisk until smooth. If icing is too thin, add more sugar a few tablespoons at a time. You want it to be pourable but somewhat thick. From here you can either use a spoon to drizzle it on the bread or transfer to a bag/bottle for piping.
