Make the Crepe Batter:
Add milk and eggs to your blender. Add the vanilla extract.
Add flour and salt on top of the liquids.
Blend everything until smooth.
Open the top spout and slowly pour in the melted butter while the blender runs on low speed.
The batter is ready to use immediately, or cover and refrigerate for up to 3 days. Whisk before using if refrigerated, adding milk if it thickens.
Cook the Crepes:
Heat an 8-inch pan over medium heat.
Add 1-2 teaspoons of butter to the hot pan and swirl until melted.
Pour 3-4 tablespoons of batter into the center of the pan.
Immediately lift the pan and tilt it in circular motions until the batter stops dripping and forms an ultra-thin layer.
Cook until the surface changes from shiny to matte, about 1-2 minutes.
Slide your spatula underneath and flip quickly.
Cook the second side for just 30 seconds. The crepe should be soft and pliable, not crispy.
Transfer to a plate and repeat with remaining batter, adding butter to the pan before each crepe.
Make the Cream Cheese Filling:
Beat softened cream cheese with powdered sugar until smooth.
Add vanilla, salt, and milk. Mix until spreadable consistency.
Make the Strawberry Filling:
Toss sliced strawberries with sugar and jam.
Let sit for 10 minutes to macerate and release juices.
Assemble:
Spread cream cheese down the center of each crepe.
Top with strawberry mixture.
Fold the sides over or roll up. Serve immediately while warm.
