In a mixing bowl, whisk together flour, sugar, baking powder, and salt. In another bowl, mix milk, egg, melted butter, and vanilla. Combine wet and dry ingredients.

In a small bowl, mix brown sugar and cinnamon. Fold half of the pancake batter into this mixture.

Preheat the griddle over medium heat and grease lightly. Test by sprinkling water.

Pour plain batter into circular shapes and add cinnamon filling on top. Cook until bubbles form and edges are golden, then flip and cook until done.

For the glaze, beat cream cheese and powdered sugar together, add milk to achieve drizzling consistency, and mix in vanilla.

Stack pancakes and drizzle with cream cheese glaze. Optionally dust with powdered sugar or add fruit.
