01 - Preheat the waffle iron according to manufacturer’s instructions.
02 - In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt until fully blended.
03 - In a separate bowl, beat the eggs, then add the milk, melted butter, and vanilla extract; mix thoroughly.
04 - Pour the wet mixture into the dry ingredients and gently stir until just combined, leaving the batter slightly lumpy to preserve fluffiness.
05 - Fold in the semi-sweet chocolate chips if using.
06 - Lightly grease the waffle iron with nonstick spray or melted butter to prevent sticking.
07 - Pour enough batter onto the center of the iron to cover the waffle grid. Close and cook for approximately 4 to 5 minutes until crisp and cooked through.
08 - Repeat the process with the remaining batter.
09 - Serve waffles warm, topped with fresh berries, whipped cream, and a drizzle of maple syrup or chocolate sauce.
