1 1/2 cups (350ml) milk (preferably 2%)
1 cup (142g) all-purpose flour (scoop and level to measure)
2 tsp granulated sugar
1/4 tsp salt
3 Tbsp (42g) unsalted butter, melted
1/2 tsp vanilla extract
3 large eggs
Butter for pan
Powdered sugar, for dusting
Desired fillings (optional)
Add milk, flour, sugar, salt, butter, vanilla and eggs to a blender, then blend on low speed until well combined, about 10 seconds.
Scrape sides and bottom of blender if there's any flour sticking and blend a few seconds longer.
Cover and chill 1 hour (or overnight if desired).
Heat a 10-inch non-stick skillet over medium heat.
Gently stir batter with a spoon just to blend separated layers.
Lightly butter skillet then lift pan and pour a scant 1/4 cup batter into pan, immediately tilt and swirl pan in circular motion to evenly coat entire bottom portion of pan with batter.
Cook until golden brown brown on bottom then use an offset spatula to lift an edge of the crepe, grab the edge of the crepe with your fingertips and flip crepe to opposite side. Cook until golden brown spots appear on bottom.
Transfer to a wire rack. Repeat until all of the batter has been used up (if needed reduce burner temperature slightly).
Dust crepes with powdered sugar and roll or fold into fourths, or fill with desired fillings then fold.
