For crepes: Blend milk, eggs, melted butter, and vanilla in the blender. Slowly add flour, then sugar and salt. Blend well.
Cover and refrigerate for 1 hour so the batter will thicken slightly.
Heat a 7-8" nonstick skillet over medium or medium-high heat.
Pour about 3-4 Tbsp of batter into the bottom of a the skillet. (Use a little oil if needed for the first crepe.) Tilt the pan to cover the bottom. Cook for 1-2 minutes. Gently use a spatula to flip the crepe. Cook for about 1-2 minutes on the second side.
For filling: Blend cream cheese in a mixing bowl till smooth. Gradually beat in the milk till the mixture is smooth. Add the dry pudding mix and the vanilla. Beat till smooth. Fold in the whipped cream.
To serve: Spoon about 1/3 cup of filling in the middle of each crepe. Fold the sides in and place on serving plate. Top with sliced berries and bananas. Serve immediately.
Notes
You can make the crepes ahead of time. Just let them cool, stack them on a plate, cover tightly with plastic wrap, and place them in the refrigerator. They will last a day or two.
I like to cook both sides of my crepes, but you can just cook for 2 minutes on one side if you prefer.
