In a large mixing bowl, combine the all-purpose flour, 2 tablespoons of granulated sugar, baking powder, baking soda, salt, and 1 teaspoon of ground cinnamon. Whisk these dry ingredients together until they are well combined and free of lumps.
In a separate medium bowl, mix together the buttermilk, large egg, melted unsalted butter, and vanilla extract. Beat the mixture until smooth and uniform in texture.
Gradually pour the wet mixture into the bowl of dry ingredients. Using a spatula or wooden spoon, stir gently until just combined. Take care not to overmix; it's perfectly acceptable for the batter to remain slightly lumpy.
Preheat a non-stick skillet or griddle over medium heat. Lightly grease the cooking surface with a small amount of butter or a spritz of cooking spray to prevent sticking.
For each pancake, pour about 1/4 cup of batter onto the preheated skillet. Allow the pancakes to cook undisturbed until small bubbles begin to form on the surface, which should take about 2-3 minutes. Carefully flip the pancakes and cook for an additional 2-3 minutes, or until they achieve a lovely golden-brown hue.
While the pancakes are cooking, prepare the churro-inspired coating. In a shallow dish, mix together the 1/4 cup of granulated sugar and 2 teaspoons of ground cinnamon until evenly combined.
Once the pancakes are cooked, immediately transfer them to the cinnamon-sugar mixture and coat each pancake generously on both sides for that delightful churro flavor.
Serve the pancakes warm, optionally drizzling them with rich chocolate sauce and garnishing with an additional sprinkle of cinnamon sugar for added indulgence.
Notes
Serve warm with chocolate sauce for extra indulgence.
