Spoon or pour the batter carefully into the donut pan. Bake at 350 degrees F for 10-12 minutes, or until a toothpick pulls clean from the baked donut.
Meanwhile, make the icing. Combine the powdered sugar, oat milk, and vanilla in a medium mixing bowl. Divide into separate bowls and add food coloring to each bowl to create any colors you’d like for the frosting. Leave a small bowl with a little white icing if you want to drizzle lines on the donuts (as pictured).
