Need help in gaining weight ,,, any comments will be helpful?

Hello guys,
I just wanted to ask whether consumption of biscuits with milk reduce the nutritions facts of biscuits

For example let's say pack of 4 biscuits count 100 calories
If I consume same 4 biscuits when mixed with milk like a milkshake reduce the calorie intake of biscuits or does it remains same?
Any health expert please help no where in internet is written about such things
