Chocolate Chip Pancakes with Cinnamon Cream

Preheat griddle to 350 °. 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 chocolate morsels. Melt 2 tablespoons butter on hot griddle. 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 procedure with remaining 2 tablespoons butter and remaining batter.
