01 - Preheat the waffle iron according to the manufacturer's instructions.
02 - In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg.
03 - In a separate bowl, beat the eggs, brown sugar, vegetable oil, buttermilk, and vanilla extract until well combined.
04 - Add the wet mixture to the dry ingredients and gently mix until just incorporated. Avoid overmixing.
05 - Fold in the grated carrots, chopped nuts, and raisins if using.
06 - Lightly grease the waffle iron with non-stick spray or melted butter. Pour enough batter onto the iron to cover the waffle grid without overflowing. Close the lid and cook for 4 to 5 minutes, or until the waffles are golden brown and crisp.
07 - Carefully remove the waffles and repeat with remaining batter. Serve warm with cream cheese glaze, maple syrup, or whipped cream as desired.
