In a mixing bowl, whisk together the self-rising flour, sugar, kosher salt, and cocoa powder until well combined.
In another bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract until fully incorporated.
Pour the wet ingredients into the bowl with the dry ingredients and gently stir until just combined.
Heat your skillet or griddle over medium heat and lightly grease if not non-stick.
Pour about 1/4 cup of batter for each pancake onto the skillet. Cook for 2-3 minutes until bubbles form on the surface.
Flip the pancakes and cook for another 1-2 minutes until slightly browned. Remove and keep warm.
Serve warm with your favorite toppings like maple syrup, whipped cream, or fresh berries.
