Molten Chocolate Cakes Recipe

Microwave the chocolate chips and butter together in a large bowl until the butter is melted. Stir with a wire whisk until chocolate is completely melted. Whisk in the eggs and egg yolks. Stir in the flour. Divide the batter between 4 buttered custard cups. Bake at 425 for 13-14 minutes or until sides are firm but the centers are soft. Remove from the oven and let stand for 1 minute. Run a knife around the edges of the cups to loosen. Invert cakes onto serving dishes. Top with whipped topping if desired.
