01 - Preheat the waffle iron following the manufacturer's guidelines.
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 uniform.
04 - Gently fold the wet ingredients into the dry mixture, stirring only until just combined to avoid overmixing.
05 - Fold in the grated carrots, chopped nuts, and raisins if desired.
06 - Lightly grease the waffle iron with non-stick spray or melted butter.
07 - Portion enough batter to cover the waffle grid. Close the iron and cook for 4 to 5 minutes or until golden brown and crisp.
08 - Carefully remove the cooked waffle and repeat with remaining batter. Serve warm with toppings such as cream cheese glaze, maple syrup, or whipped cream.
