01 - Preheat your waffle iron according to manufacturer's instructions until ready for batter.
02 - In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until evenly distributed.
03 - In a separate bowl, beat eggs thoroughly. Add buttermilk, melted butter, vanilla extract, and red food coloring, whisking until smooth and fully incorporated.
04 - Pour wet ingredients into dry ingredients. Stir gently until just combined—avoid overmixing. Small lumps in the batter are acceptable and ensure tender waffles.
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 waffle iron, adjusting based on your iron's capacity. Cook for 3–5 minutes until waffles are crisp and cooked through.
07 - Remove waffles and serve immediately while warm. Drizzle with maple syrup and top with whipped cream and fresh berries if desired.
