Preheat your waffle iron according to the manufacturer's instructions.

In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt until well blended.

In a separate bowl, whisk together the buttermilk, eggs, melted unsalted butter, and vanilla extract until thoroughly combined.

In a small bowl, mix melted butter, brown sugar, and ground cinnamon until well combined to create your swirl.

Lightly grease the preheated waffle iron. Pour approximately ½ cup of the batter into the center of the waffle iron, and pipe a spiral of the cinnamon mixture over the batter.

While the waffles are cooking, prepare the cream cheese drizzle by beating the cream cheese until smooth, then gradually mix in the powdered sugar and milk.

Once your waffles are cooked to perfection, carefully remove them and serve warm, drizzling generously with the creamy cream cheese topping.
