Baby won't drink milk

My 10 month old daughter isn't drinking her milk. She recently switched from breastmilk to formula, and doesn't seem to be taking the transition very well. I'm pretty much dried up, so she has no choice but to take the formula. The pediatrician suggested sneaking the milk into her foods. I tried putting milk in her oatmeal, mashed potatoes, and sweet potatoes, but is there anything else. Please share any recipes you may have that include milk as the base, whether it's a meal or a snack. She needs her calories and she is missing out on them. I don't want her to get dehydrated also.
