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 until thoroughly blended.
03 - In a separate bowl, beat the eggs, light brown sugar, vegetable oil, buttermilk, and vanilla extract until the mixture is well blended.
04 - Gently pour the wet mixture into the dry ingredients and stir until just combined. Do not overmix to preserve a tender texture.
05 - Carefully fold in the grated carrots along with walnuts or pecans and raisins if using.
06 - Lightly grease the waffle iron with non-stick spray or melted butter.
07 - Pour enough batter onto the waffle iron to just cover the grid surface. Cook for 4 to 5 minutes, or until waffles are golden brown and crisp as directed by your appliance.
08 - Remove waffles and repeat cooking process with remaining batter. Serve warm, optionally garnished with cream cheese glaze, maple syrup, or whipped cream.
