01 - Whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon in a large bowl until thoroughly combined.
02 - In a separate bowl, whisk milk, eggs, melted butter, and vanilla extract until smooth and fully incorporated.
03 - Pour wet ingredients into dry ingredients. Mix gently until just combined—small lumps are acceptable. Let batter rest for 5 minutes to thicken slightly.
04 - Heat a non-stick skillet or griddle over medium heat. Lightly grease with additional butter as needed.
05 - Pour 1/4 cup batter per pancake onto the griddle. Cook until bubbles form on surface and edges appear set, approximately 2-3 minutes. Flip and cook until golden brown, another 2-3 minutes.
06 - Combine 1/4 cup sugar and 2 teaspoons cinnamon in a small bowl. Mix until evenly blended.
07 - Brush warm pancakes lightly with melted butter. Press both sides into cinnamon sugar mixture for even coating.
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 coated pancakes on plates. Drizzle warm chocolate sauce generously over top or serve alongside for dipping.
