Place all ingredients in a blender and combine until smooth. Allow the batter to rest for 1 hour.
Heat a small non-stick skillet over medium heat. Melt 1 teaspoon butter in the pan. Pour 1 ounce of the batter into the center of the pan and swirl with a spatula to spread evenly.
Cook for 30 seconds and flip. Cook for an additional 15 seconds and transfer to a baking sheet. Be sure the crepe is flat so it can cool. Repeat with remaining batter.
After the crepes have cooled completely, stack them and store in sealable plastic bags in the refrigerator for several days or in the freezer for up to two months.
Serve crepes with powdered sugar, jam, whipped cream or your favorite fillings.
Notes
To make savory crepes: Add 1/4 teaspoon salt and 1/4 cup chopped fresh herbs or spinach to the batter.
To make sweet crepes: Add 2 tablespoons sugar and 1 teaspoon vanilla extract or 2 tablespoons of your favorite liqueur to the batter.
When using frozen crepes, thaw on a cooling rack before carefully peeling apart.
