Combine 1 1/2 cups of all purpose flour, 1/4 cup of unsweetened cocoa powder, 1/3 cup of granulated sugar, 1/2 teaspoon of salt, 3/4 teaspoon of baking soda and 1 1/2 teaspoons of baking powder in a large bowl
Use the whisk to form a well in the center of the bowl and add 1 1/3 cups of buttermilk, 3 tablespoons of melted butter, 2 eggs and 1 teaspoon of vanilla extract
Mix until the ingredients are just combined
Cover the bowl with a clean towel and rest for 10-15 minutes
Place a flat griddle or wide skillet over medium heat and grease with butter or non-stick spray
Drop batter onto the warm greased skillet and sprinkle each pancake with chocolate chips
Once bubbles form over the surface of the pancake, carefully flip and cook until the center of each pancake feels set to a light touch
