In a blender or with a stick blender

Cup of Yum
1. Place the milk, eggs, melted butter, vanilla, sugar, and salt in a blender or tall jug.
2. Next, add the flour and cocoa powder.
3. Blend until the crepe batter is smooth, while making sure to scrape down the sides of the jug half way through to prevent the flour from sticking to the sides.
4. Let the chocolate crepe batter rest for at least 15 minutes.

In a bowl with a whisk

1. Place the flour, cocoa powder, sugar, and salt in a large bowl. Whisk to combine.
2. Add a little of the milk , while whisking, to form a smooth paste. Between ½ - 1 cup.
3. Then add the eggs, butter, and vanilla, and whisk to combine. Whisk in the rest of the milk until smooth.
4. Let the chocolate crepe batter rest for at least 15 minutes.

Cooking the chocolate crepes

1. Preheat a 10 inch non-stick pan over medium heat.
2. Brush a layer of butter on the heated pan. I use a silicone brush, but you can use a butter soaked paper towel or cloth as well.
3. Always give the crepe batter a mix before you make each crepe. This makes sure the flour is uniformly mixed through.
4. Scoop up about ¼ cup of the batter (using a ladle or measuring cup). Pour the batter into the hot pan while swirling it to coat the bottom of the pan. Make sure the batter is spread as evenly as possible. If there are any large bald spots, just place a little batter in there to cover the spots. (The first crepe may not come out perfect, and is usually the "test" crepe.)
5. Return the pan back to the heat to let the crepe cook.
6. For extra soft crepes – cook the crepes only until they are just set at the surface (about 30 seconds) and there’s no browning on the edges. You can flip over the crepe gently, and cook for a few seconds on the other side (optional), or remove the crepe from the pan and place it on a plate or wire rack.
7. For classic crepes – cook the crepes until the edges are starting to become a little crisp (about 40 - 60 seconds). Flip the crepes over and cook for a further 10 – 15 seconds on the other side.
8. Repeat until all the batter is used up (remember to mix the batter each time).
9. Stack the cooked crepes on a plate or wire rack until you've made all the chocolate crepes.
10. Serve with your choice of filling. See the post for serving suggestions.
