Preheat the oven to 350(f) degrees. Grease a 9 by 13-inch sheet pan & set aside.

In a large mixing bowl whisk together sugar, butter, eggs, vanilla & ricotta until well blended.

Sift in flour, baking powder, baking soda, salt, lemon juice & lemon zest. Slowly add the milk & stir until just incorporated. A few lumps are okay.

Fold in the berries & transfer to the prepared baking sheet. Using an offset spatula spread batter into an even layer.

Bake for 20 to 25 minutes, until golden & cooked throughout. To serve, dust with powdered sugar & a drizzle of maple syrup.
