01 - Preheat your waffle iron according to manufacturer's instructions.
02 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well blended.
03 - In a separate bowl, whisk the ricotta, milk, eggs, melted butter, lemon zest, lemon juice, and vanilla until smooth and creamy.
04 - Pour the wet ingredients into the dry ingredients and gently fold until just combined. Do not overmix; a few small lumps are acceptable.
05 - Lightly grease the waffle iron with cooking spray or melted butter. Pour approximately 1/2 cup batter per waffle and cook until golden brown and crisp, about 3 to 5 minutes.
06 - Serve immediately topped with fresh berries, maple syrup, powdered sugar, or a sprinkle of extra lemon zest.
