How do you make your warmed bottles?

My baby is boujee and refuses to take cold formula from the fridge. I've been doing the pitcher method and just warm the bottles. But as you know, waiting in the middle of the night for a bottle feels like hours instead of minutes.

I've thought about getting one of those dispensers for warm water. I've found that the formula I use dissolves better if the water is warmed, otherwise it clumps really bad and I have to shake tf out of it, which creates bubbles, etc, etc.

Just curious as to what everyone else does.
