01 - Whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon in a large bowl until evenly combined.
02 - In a separate bowl, whisk milk, eggs, melted butter, and vanilla extract until fully blended and smooth.
03 - Pour wet ingredients into dry ingredients and mix until just combined. Avoid overmixing to keep pancakes tender. Let batter rest for 5 minutes.
04 - Heat a non-stick skillet or griddle over medium heat and lightly grease with butter.
05 - Pour 1/4 cup of batter per pancake onto the griddle. Cook until bubbles form on the surface and edges appear set, then flip and cook until golden brown, approximately 2–3 minutes per side.
06 - Combine 1/4 cup sugar with 2 tsp cinnamon in a small bowl, mixing thoroughly until evenly blended.
07 - While pancakes are still warm, brush lightly with melted butter if desired, then generously dust both sides with cinnamon sugar mixture.
08 - Place chopped chocolate and cream in a microwave-safe bowl. Microwave in 20-second intervals, stirring between each until completely smooth and glossy.
09 - Stack pancakes on plates and drizzle with warm chocolate sauce or serve sauce on the side for dipping.
