Make the Pancake Batter:
In a mixing bowl, whisk together flour, sugar, baking powder, and salt. In a separate bowl, combine milk, eggs, melted butter, and vanilla. Slowly stir the wet ingredients into the dry until just combined — do not overmix.
Prepare the Cinnamon Swirl:
Mix melted butter, brown sugar, and cinnamon in a small bowl until smooth. Pour the mixture into a piping bag or plastic zip bag. Snip off a tiny corner for swirling.
Cook the Pancakes:
Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil. Pour about ¼ cup of batter for each pancake. Once bubbles form on the surface, swirl the cinnamon mixture in a spiral pattern on top. Flip gently and cook until golden brown on both sides.
Make the Cream Cheese Drizzle:
Whisk cream cheese, powdered sugar, milk, and vanilla until smooth. Adjust consistency with more milk if needed.
Serve:
Stack pancakes, drizzle with cream cheese glaze, and serve warm for the perfect bakery-style breakfast.
