Preheat your waffle iron according to manufacturer's instructions, setting to medium-high temperature.

In a large mixing bowl, whisk together flour, sugar, baking powder, baking soda, and salt.

In a separate bowl, mix buttermilk, eggs, melted butter, and vanilla extract. Pour this mixture into the bowl with dry ingredients.

In a small bowl, combine melted butter, brown sugar, and ground cinnamon. Stir until it forms a smooth paste.

Lightly grease the preheated waffle iron, pour about ½ cup of batter, and pipe the cinnamon swirl in a zigzag pattern over it. Cook for 3-4 minutes.

Prepare the cream cheese drizzle by beating softened cream cheese, gradually adding powdered sugar and milk until pourable.

Once the waffles are golden brown, drizzle with cream cheese glaze and serve.
