For the past 4 days or so I've been eating a slice of chocolate cake & 2 cookies every night... am I going to gain a bunch of weight from this? I weigh 114 right now and eat healthy during the day.

I read that excessive consumption of calories that exceeds the body’s needs may lead to obesity, which is associated with diabetes and heart trouble. Since neither medicine nor physical activity can take the place of proper eating habits, a good suggestion is to reduce the intake of sweets. Therefore, no more sweets at night! Stay healthy.
