Using a blender or immersion blender, whiz together the 4 eggs, 1 ¾ cups of whole milk, sugar, vanilla extract, and salt until everything has blended, about 10 seconds. Add in the flour and whiz until the batter is smooth, about 20 seconds. Pour in the unsalted butter and whiz until combined, about 10 seconds.
Transfer the batter into a large bowl, with an opening sized so that you can easily use a ¼ cup measuring cup to scoop up the batter. Allow the batter to sit for at least 5 minutes, but up to 24 hours. If resting the batter longer than 30 minutes, cover and transfer it to the refrigerator.
When you are ready to make the crepes, remove the batter from the refrigerator and allow to sit for at least 10 minutes. Check the consistency of the batter. It should be the consistency of heavy cream. If the batter feels too thick, whisk in additional milk by the tablespoon, up to ½ cup more.
Preheat a 10 or 12-inch skillet or crepe pan on medium to medium-high heat (I fluctuate between 6/9 and 7/9 on my stove setting). In a small bowl, melt about 2 tablespoons of butter. When the pan is hot, using a small silicone brush, brush on a thin layer of butter. Alternatively, melt and swirl the butter around the pan.
Scoop on ¼ of the crepe batter in the center of the pan. Quickly, using a crepe spreader, evenly spread the batter in a circular motion until the crepe is thin and the batter has reached the edge of the pan. You can also quickly swirl the pan around so the crepe batter spreads into a thin layer, but I don't always have success getting perfectly round crepes this way.
Cook the crepe until the edges begin to dry and lift from the sides of the pan, and the bottom is golden brown, about 1 minute. Gently flip the crepe over using a spatula and smooth out any folds. Cook for an additional 20-30 seconds. Slide the crepe off the pan onto a plate to serve, or to a cooling rack if you are making more. You can stack on the crepes as they finish cooking.
Repeat with remaining crepes, brushing butter on the pan each time before you pour on the crepe batter.
Serving the crepes
Spread the nutella on the crepes. I use about 2 teaspoon per crepe, otherwise I find it too sweet. Feel free to use more or less as you prefer. I usually do two different folding methods.First method: Fold the crepe in half, and then in half again, so you get a triangle.Second method: Fold the crepe into thirds, but so that it forms a triangle.
Top with powdered sugar, fresh whipped cream, strawberries and/or bananas.
This recipe is adapted from my Basic French Crepes. Find lots of tips in that post on how to make the perfect crepes.The amount of milk varies because of the exact size of your egg and the exact amount of flour you use. To store: If you plan to store the crepes, you can refrigerate them in as a stack and slowly peel off each crepe as you want to eat it. You can also freeze them with a layer of parchment paper in between, so they do not stick together frozen. Gently heat the crepes on a pan before serving.
