01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk the ricotta, eggs, milk, melted butter, lemon zest, lemon juice, and vanilla until smooth.
03 - Gently fold the wet ingredients into the dry ingredients until just combined; some small lumps are fine. Do not overmix.
04 - Fold in the blueberries gently.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.

07 - Flip and cook for another 1–2 minutes until golden and cooked through.
08 - Repeat with remaining batter, greasing the pan as needed.
09 - Serve warm with maple syrup, extra blueberries, and a dusting of powdered sugar if desired.
