01 -  In a large mixing bowl, whisk ricotta cheese, eggs, milk, melted butter, orange zest, and vanilla extract until creamy and well combined. 
 02 -  In a separate bowl, blend all-purpose flour, granulated sugar, baking powder, and salt until even. 
 03 -  Add the dry mixture to the wet ingredients and fold gently until a thick, slightly lumpy batter forms. Avoid overmixing. 
 04 -  Carefully fold three-fourths cup of the mixed berries into the batter, setting aside the remaining berries for garnish. 
 05 -  Warm a non-stick skillet or griddle over medium heat and lightly coat with butter. 
 06 -  For each pancake, spoon about one-fourth cup of batter onto the skillet. Cook for two to three minutes until bubbles appear and edges set. 
 07 -  Turn each pancake and continue cooking for one to two minutes, until golden brown and cooked through. Repeat using remaining batter and butter as needed. 
 08 -  Plate the pancakes warm and top with reserved berries and powdered sugar if desired.
