Final answer:
The student is inquiring about what typically tops Red Velvet Pancakes, which is usually a cream cheese frosting, icing, glaze, or spread. Without being given specific additional ingredients for the topping, we can't complete the sentence definitively.
Step-by-step explanation:
The student is likely asking for a word to complete the sentence. Given the context of cooking, the missing word would theoretically describe a form of topping or glaze for the Red Velvet Pancakes.
However, the question does not include sufficient information to provide an exact word to fill in the blank.
To make Red Velvet Pancakes using the ingredients provided (1 egg, 1 tablespoon vegetable oil, 2 boxes of pancake mix, and half a gallon of milk), one would follow the instructions on the pancake mix box and add red food coloring to achieve the red velvet look.
The pancakes would be typically topped with cream cheese frosting, icing, glaze, or a cream cheese-based spread.
