Preheat oven to 400 degrees Fahrenheit.
In a large mixing bowl, combine, vegan margarine (Earth Balance) with sugar, orange juice, almond milk, vanilla, and salt.
In a separate bowl, mix oats, flour, and baking powder. Combine wet ingredients with dry until well-incorporated, then gently fold in your blueberries.
Prepare your muffin tin with cooking spray and/or liners. Spoon batter into tins until they are 3/4 full or until batter is evenly distributed between 12 muffin holders. Sprinkle the tops of batter with sparkling sugar sprinkles, if desired.
Bake muffins at 400 degrees F for 18-20 minutes, or until a fork comes out clean and tops are beginning to turn golden brown.
Serve warm.
