Looking for the best frozen custard in Wisconsin? You have tons of options. Wake up your sweet tooth, because we're about to show you the best sweets shops in the state.

Our status as the dairy state is what cemented frozen custard's history in Wisconsin - we had the necessary ingredients at our fingertips. The FDA has rules on what makes something ice cream or frozen custard. Custard has to contain at least 10% butterfat and 1.4% egg yolks. The yolks are the crucial part. Most ice creams have no eggs. One other factor that gives custard its unique texture? There's little to no air in it. The large machines that create it introduce little air. The best guess is that our very first custard place opened in 1938 - Gille's in Milwaukee. The rest is, as they say, history.

In no particular order, here are 15 places that folks rave about for serving the best frozen custard in Wisconsin.

1. Robert's Frozen Custard - Germantown

Probably the fanciest frozen custard place you'll ever see, Robert's has a fireplace and an inviting interior to bring you in to enjoy their delicious custard year-round. There's a rumor of a cream puff sundae from Robert's that seems worth investigating - for scientific purposes, obviously. Located at N112 W16040 Mequon Rd, Germantown, WI 53022.
