Get your electric griddle or non-stick skillet heating up on moderate-high heat.
Mix together flour, sugar, baking powder, baking soda, and salt in a bowl.
Create a well in the center of the flour mixture and set it aside.
In another bowl, combine milk, ricotta, eggs, and vanilla until blended.
Add melted butter, lemon zest, and lemon juice to the milk mixture and mix until combined (it might look a bit curdled, but that's normal).
Pour the milk mixture into the flour mixture and whisk gently until just combined (a few lumps are okay).
Scoop 1/3 cup of batter onto a buttered griddle or skillet and cook until bubbles form on the surface and the bottom is golden brown, then flip and cook the other side until golden brown.
Serve warm with powdered sugar and maple or berry syrup, if desired. Enjoy!
