Place ingredients in a blender starting with wet and ending with flour. This will prevent the batter from having flour clumps.
1 cup milk, 2 large eggs, 2 teaspoons granulated sugar, 1 teaspoon vanilla extract, ¼ teaspoon salt, 1 tablespoon unsalted butter, ¾ cup all-purpose flour
Blend until smooth.
Refrigerate the batter for at least 30 minutes, or overnight.
Heat up crepe or non-stick pan. Pour ¼ cup of batter into pan, swirl around the pan.
Once the batter appears dry and light yellow, flip the crepe. Cook for 10 seconds and remove onto a plate.
Repeat until all batter is used.
Fill or top crepes and serve.
Notes
You can store the batter in a blender jar but it is better to pour it into a bowl or a container. Most blender manufacturers do not recommend storing the liquid in blenders for longer periods of time.
