01 - Preheat your waffle iron according to the manufacturer's instructions.
02 - In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt until well incorporated.
03 - In a separate bowl, whisk the eggs, buttermilk, melted butter, vanilla extract, and red food coloring until thoroughly blended and uniform in color.
04 - Pour the wet ingredients into the dry ingredients and stir gently until just combined. Avoid overmixing; small lumps are acceptable and will result in tender waffles.
05 - Lightly grease the preheated waffle iron. Pour approximately 1/2 cup of batter into the center and close the lid. Cook until the waffles are crisp and cooked through, about 3 to 5 minutes per batch.
06 - Repeat the cooking process with the remaining batter, lightly greasing the iron between batches as needed.
07 - Serve the waffles immediately while warm. Drizzle with maple or chocolate syrup, and top with whipped cream and fresh berries if desired.
