Notes
Room Temperature Ingredients: Ensure that the butter and eggs are at room temperature before beginning to make the mega chocolate chip cookies. Room temperature butter mixes more easily with the other ingredients, resulting in a smoother and more uniform cookie dough. Room temperature eggs incorporate better into the batter, leading to a lighter and fluffier texture in the finished cookies.
Proper Mixing Technique: When combining the wet and dry ingredients, avoid overmixing the cookie dough. Overmixing can result in tough cookies. Beat the eggs for 3-4 minutes until they are light and fluffy, but mix the remaining ingredients on low speed just until combined. Stir in the flour and chocolate chips until they are just incorporated into the dough to prevent gluten development, which can make the cookies tough.
Baking Tips: Bake the mega chocolate chip cookies at 350º Fahrenheit for 18-21 minutes, rotating the cookie sheets between upper and lower racks halfway through baking for even browning. Keep an eye on the cookies as they bake and remove them from the oven when the edges are golden brown but the centers are still slightly soft. The cookies will continue to firm up as they cool on the baking sheets before transferring to cooling racks. To maintain their softness, store the cooled cookies in a tightly covered container with a piece of bread, which helps to retain moisture.
