This Soft-Serve Frozen Custard Feels Like a Sweet Treat From ‘Happy Days’

Before TikTok challenges and Instagrammable lattes, there was frozen custard and jukeboxes. And no show captured that retro Americana quite like Happy Days. While the series was filmed in Hollywood, it was proudly set in 1950s Milwaukee, and the spirit of the Midwest was baked right into every episode. Arnold’s Drive-In, the show’s beloved hangout spot, wasn’t just a fictional set, it was inspired by two real Wisconsin institutions. And if you’re from the area, you already know what those diners likely served in abundance: soft, creamy frozen custard. So in honor of the iconic show, we’re sharing a nostalgic recipe that’s perfect for scooping into a cone or piling high in a sundae glass.

Frozen custard is a Milwaukee legacy

Milwaukee isn’t just known for its cheese and beer. It’s also considered the frozen custard capital of the world. Unlike regular ice cream, frozen custard contains egg yolks, giving it a richer texture and smoother consistency. By law, frozen custard must contain at least 1.4 percent egg yolk solids, which creates a richer, silkier texture, It’s also churned more slowly, which means less air and a denser, creamier treat. While the treat dates back to New York’s Coney Island in the early 1900s, it found a true home in the Midwest, particularly in Milwaukee, where local stands like Kopp’s, Leon’s and Gilles have been serving it for decades.

So it’s no surprise that Happy Days creator Garry Marshall looked to Milwaukee’s beloved Milky Way and Pig ’n’ Whistle when dreaming up Arnold’s Drive-In. One of those restaurants, The Milky Way, would eventually become none other than Kopp’s Frozen Custard (still slinging scoops in Glendale today).

Welcome to Arnold’s (a.k.a. Kopp’s)

If you can picture Fonzie giving a thumbs up over a sundae or Richie and Joanie sharing a cone in a booth, you’re already halfway to tasting this frozen custard. Arnold’s may have been a set, but the atmosphere was rooted in Milwaukee tradition right down to the frozen treats. According to Kopp’s manager Scott Borkin, the show’s exterior was modeled after the original Milky Way building, complete with carhops. And inside? The vibe was all Pig ’n’ Whistle diner charm.

Tips for getting your frozen custard just right

Making homemade ice cream, or frozen custard for that matter, can feel intimidating. But with these helpful tips, your frozen treat will have you, well, happy-for-days.

• Chill thoroughly: Custard base must be cold before churning or it won’t set properly.
• Use high-fat dairy: Whole milk and heavy cream give the best texture and richness.
• Skip the churn (in a pinch): Don’t own an ice cream maker? You can freeze the custard base after refrigerating in a baking dish or loaf pan and stir every 30 minutes until set. This breaks up the ice crystals for a smoother texture. But for classic custard, a machine works best.

How to make classic vanilla soft-serve frozen custard

This frozen custard may not come with a booth full of classmates or a jukebox playing the Big Bopper, but it’s every bit as authentic to the spirit of Happy Days. Here’s an easy recipe to make at home from Tastes of Lizzie T. Enjoy as-is or blend it up into a milkshake with your favorite toppings!

Ingredients:

• 2 cups heavy cream
• 1 cup whole milk
• ⅔ cup granulated sugar
• Pinch of salt
• 6 large egg yolks
• 2 tsp. vanilla extract

Directions:

• Total time: 4 hours 40 minutes (including chilling)
• Yield: 6 servings

1. Add the cream, milk, sugar and salt to a small saucepan over medium low heat. Simmer about three to five minutes, or until sugar dissolves. Then, remove from the heat.
2. In a separate bowl whisk the egg yolks. Drizzle about ½ cup of the warm milk liquid into the egg yolks, whisking constantly.
3. Add the egg-milk mixture back into the pot, then add the vanilla. Return the pot to a medium-low heat and cook until it starts to thicken. Take off the heat and pour into a mesh strainer over a bowl.
4. Cool the custard to room temperature, then cover and refrigerate to cool completely. This will take at least three to four hours to overnight.
5. Churn the custard in an ice cream maker according to manufacturer directions. Or, see above for no-churn instructions. Serve soft serve or firm it up in the freezer.
