Put all crepe ingredients (from flour to vanilla) in blender and process until smooth. Let mixture rest for at least 30 minutes (you can skip this if you're in a rush). Alternatively, you can make the batter the day before and keep it in fridge overnight. If refrigerated overnight, let rest at room temperature for 30 minutes before using.
Place a 7- or 8-inch nonstick skillet (or crepe pan) over medium heat. Coat with a little bit of butter. Pour about ¼ cup batter in pan and gently tilt and swirl pan until batter evenly coats the bottom (if you're using a 7-inch pan, your crepes will be a little thicker. If you're using an 8-inch pan, they'll be a little thinner. Feel free to use a little more or less batter based on pan size and preference).
Let cook for about 1-1 ½ minutes until crepe is turning golden on bottom and edges are pulling away from pan. You can either use your fingers or a spatula to pull edges up and when ready, flip. Cook for another minute before removing crepe from pan to a plate.
Continue with remaining batter, adding a little butter to pan in between each.
Top crepes with maple cream cheese filling or the filling of your choice and fold over.
