01 - Preheat the waffle iron according to manufacturer’s directions.
02 - In a large mixing bowl, whisk together flour, brown sugar, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves until evenly combined.
03 - In a separate bowl, whisk whole milk, pumpkin puree, eggs, melted butter, and vanilla extract until smooth.
04 - Add wet ingredients into the bowl of dry ingredients and gently stir until just incorporated, avoiding overmixing.
05 - Lightly grease the waffle iron. Pour enough batter to cover the waffle grid, close, and cook until waffles are golden and crisp. Repeat with remaining batter.
06 - In a small bowl, combine ricotta cheese, honey or maple syrup, vanilla extract, and orange zest (if using) until mixture is creamy.
07 - Stack waffles on serving plates, spreading ricotta mixture between layers. Finish with a generous spoonful of ricotta, a drizzle of maple syrup, and a sprinkle of toasted nuts or powdered sugar if desired.
