In a large mixing bowl, whisk together the all-purpose flour, baking powder, and kosher salt.
In a separate bowl, beat the eggs and sugar until light and fluffy.
Stir in the vanilla extract, ricotta cheese, and milk until well combined.
Gradually add the flour mixture to the wet ingredients, mixing gently to avoid overworking the batter.
In a small bowl, melt the butter in the microwave or on the stovetop. Once melted, let it cool slightly before drizzling it into the pancake batter.
Gently fold until just combined; it’s okay if there are a few lumps.
Place a skillet or griddle over medium heat and add a small amount of butter to coat the surface. Allow it to melt and bubble before you start cooking the pancakes.
Using a 1/4 cup measuring cup, pour the batter onto the skillet for each pancake. Cook until bubbles form on the surface and the edges look set, about 2-3 minutes.
Carefully flip and cook for another 2-3 minutes on the other side until golden brown. Repeat with the remaining batter, adding butter to the skillet as needed.
In a small bowl, combine the softened butter with blueberry preserves and a pinch of kosher salt. Mix until smooth and well combined. Adjust the sweetness to your liking by adding more or less blueberry preserves.
Stack your fluffy ricotta pancakes on a plate, slather generously with the salted blueberry butter, and top with fresh blueberries. Add a drizzle of syrup, a dusting of powdered sugar, or a dollop of whipped cream for an extra special touch.
