In a mixing bowl, whisk together 1 ¾ cups of all-purpose flour, 2 tablespoons of sugar, 1 tablespoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt.

In a separate bowl, blend 1 ¾ cups of buttermilk, 2 large eggs, ½ cup of melted butter, and 1 teaspoon of vanilla extract.

Gradually pour the wet mixture into the dry ingredients, stirring gently until just combined.

In another bowl, combine 1 ½ cups of all-purpose flour, 1 tablespoon of cocoa powder, 2 tablespoons of sugar, 1 tablespoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt.

In a different container, mix 1 ¾ cups of buttermilk, 1 large egg, ½ cup of melted butter, 1 teaspoon of vanilla extract, and 1 tablespoon of red food coloring until smooth.

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

Pour about ½ cup of the classic batter onto the center of the waffle iron, then add the same amount of the red velvet batter.

Swirl the two batters together with a toothpick or skewer.

Close the waffle iron and cook until golden brown and crisp, about 5 to 7 minutes.

Carefully remove the waffles and let them cool slightly on a wire rack.

Serve warm topped with whipped cream, fresh berries, or maple syrup.
