01 - Whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon in a large bowl until evenly distributed.
02 - Whisk milk, eggs, melted butter, and vanilla extract in a separate bowl until fully blended.
03 - Pour wet ingredients into dry ingredients and stir until just combined. Avoid overmixing. Let batter rest for 5 minutes to thicken slightly.
04 - Heat a non-stick skillet or griddle over medium heat. Lightly grease with butter.
05 - Pour 1/4 cup batter per pancake onto the griddle. Cook until bubbles form on the surface and edges appear set, about 2 to 3 minutes. Flip and cook until golden brown, 2 to 3 more minutes.
06 - Combine 1/4 cup sugar and 2 tsp cinnamon in a small bowl. Mix until uniform.
07 - Brush warm pancakes lightly with melted butter if desired. Dust both sides generously with cinnamon sugar mixture while still warm.
08 - Place chopped chocolate and cream in a microwave-safe bowl. Microwave in 20-second intervals, stirring between each, until smooth and glossy.
09 - Stack coated pancakes on plates. Drizzle chocolate sauce over the top or serve alongside for dipping.
