In a large mixing bowl, combine the first six ingredients (dry ingredients).
In a smaller bowl, combine the remaining ingredients (wet ingredients).
Mix the wet mixture into the dry mixture and stir only until just combined.
Grease a 12-space muffin tin, pour the batter into the tin and bake for 22-25 minutes or until lightly browned.
In a small, shallow bowl, combine the melted Earth Balance and the orange juice.
In a separate small, shallow bowl, place the ½ cup sugar for topping.
When the muffins have cooled slightly, dip each muffin top into the Earth Balance-orange mixture (just to coat), then into the sugar. Set aside and allow to cool completely.
