Place all ingredients for the crepe batter into a blender. That includes milk, eggs, oil, vanilla, flour, sugar, cocoa powder, butter, and salt. Blend until smooth.
Heat non-stick pan over medium low on stove. Spray with non-stick cooking spray.
Pour batter into pan, about ¾ cup for an 8-inch pan. Pick up pan from the burner and tilt to spread the batter around the bottom of the pan. Moving it in a circular tilting fashion will spread the batter out evenly. Batter should go to the ends of the bottom part of the pan.
When the top is noticeably cooked, flip the crêpe to lightly brown the other side.
Repeat process to cook the remaining crêpes, setting finished crêpes on plate with parchment paper between them to prevent sticking.
Serve the crepes topped with your favorite topping, such as chocolate sauce, berries, whipped cream.
