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.

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

Pour the wet ingredients into the dry ingredients and stir gently until just combined.

In a small bowl, mix together the melted butter, brown sugar, and ground cinnamon until well blended.

Lightly grease the preheated waffle iron. Pour about ½ cup of the waffle batter into the center, then pipe the cinnamon mixture on top.

Cook for 3 to 4 minutes, or until the waffles are golden brown and crisp.

In a mixing bowl, beat the cream cheese until smooth, adding powdered sugar and milk for desired consistency.

Serve the waffles immediately, drizzled with the cream cheese icing and toppings of your choice.
