Prepare the batter: In a medium bowl, whisk together the Bisquick pancake mix, milk, eggs, and vanilla extract until smooth.
Heat the pan: Heat a non-stick frying pan or skillet over medium heat and lightly grease it with melted butter or oil.
Cook the crepes: Pour about 1/4 cup of the batter onto the pan, swirling it to evenly coat the bottom. Cook for 1-2 minutes until the edges start to lift, then flip and cook for another 1 minute.
Serve: Remove the crepe from the pan and place it on a plate. Repeat with the remaining batter.
Fill and enjoy: Fill your crepes with your favorite fillings—sweet options include Nutella, whipped cream, or fresh fruit, while savory options like cheese, ham, or spinach are also great choices. Fold or roll the crepes and serve immediately.
