01 - Preheat your waffle iron according to manufacturer's instructions until ready for baking.
02 - In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well blended.
03 - In a separate bowl, beat eggs thoroughly, then add buttermilk, melted butter, vanilla extract, and red food coloring. Whisk until smooth and uniform.
04 - Pour wet ingredients into dry ingredients and stir gently until just combined. Stop mixing when a few small lumps remain—do not overmix.
05 - Lightly grease the preheated waffle iron with nonstick cooking spray or a small amount of melted butter.
06 - Pour approximately 1/2 to 2/3 cup batter into the center of the waffle iron, adjusting quantity based on your iron's specifications.
07 - Close lid and cook for 3 to 5 minutes, or according to your waffle iron instructions, until waffles are crisp and cooked through.
08 - Remove waffles carefully and serve immediately while warm. Drizzle with maple syrup and top with whipped cream and fresh berries as desired.
