In a medium bowl whisk milk and eggs. Add melted butter, stir and set aside.
In a large bowl combine flour, sugar and salt. Add egg mixture and whisk until evenly combined.
Heat 10-inch non-stick pan(s) over medium-high heat. When hot add 1 teaspoon of oil, swirl in bottom of pan and wipe away excess with paper towel.
Pour ⅓ cup batter into the hot pan. Immediately tilt and swirl the pan so the batter coats the entire surface as quickly as possible. Cook until lightly browned, about 1 minute.
Flip crepe, cook for another 1½-2 minutes. Transfer to a plate.
Return pan to heat, add more oil if needed. Using paper towel continue wiping away any excess oil and flecks of cooked crepe batter.
Repeat until all batter is used stacking crepes on top of each other as you go. Cool completely before assembling Crepe Cake.
