Creating these Fudgy Brownie Waffles is simple and straightforward. Follow these steps to make them:

1. Preheat the Waffle Iron: Set your waffle iron to medium-high heat to ensure even cooking.
2. Mix Dry Ingredients: In a large bowl, combine flour, cocoa powder, sugar, baking powder, baking soda, and salt. Whisk until well combined.
3. Combine Wet Ingredients: In a separate bowl, beat the eggs. Then, add the milk, vegetable oil, and vanilla extract. Mix until smooth.
4. Combine Mixtures: Gradually fold the wet ingredients into the dry ingredients. Stir until just combined; some lumps are okay.
5. Add Chocolate Chips: If you are using chocolate chips, fold them into the batter now.
6. Cook the Waffles: Lightly grease the waffle iron with cooking spray or oil. Pour an appropriate amount of batter onto the hot surface (about 1/2 cup, depending on your waffle iron). Close the lid and cook according to the manufacturer's instructions (usually about 3-5 minutes).
7. Remove and Serve: Carefully remove the waffle and keep it warm in the oven while you repeat with the remaining batter.
8. Add Toppings: Once all the waffles are cooked, serve them warm with whipped cream, fresh berries, or a drizzle of chocolate syrup.
