• Preheat griddle to 350 degrees F.
• In a large bowl, combine flour, sugar, baking powder, and salt.
• In a small bowl, combine milk, egg yolks, and 3 tablespoons melted butter; add to flour mixture, whisking until smooth.
• In a small bowl, beat egg whites at medium-high speed with an electric mixer until stiff. Gently fold into batter. Gently fold in mini chocolate chips.
• Spray griddle or pan with cooking spray. Ladle about 1/4-cup batter for each pancake onto hot griddle. Cook pancakes for 2 to 3 minutes, or until tops are covered with bubbles and edges look cooked. Turn and cook the other side. Repeat with cooking spray and remaining batter.

Cinnamon Cream:

• In a medium bowl, beat cream at medium-high speed with an electric mixer until thickened. Gradually beat in powdered sugar and cinnamon, beating until stiff peaks form. Cover and chill.
• Serve pancakes with Cinnamon Cream and maple syrup.
