Wisconsin Frozen Custard
intro
Ultra-silky, dense slow-churned frozen custard, Wisconsin’s iconic dairy state treat, with rich egg yolk depth and far less air than standard ice cream.
Ingredients
Steps
Heat dairy base
Combine 480ml heavy whipping cream, 240ml whole milk, 65g (1/3 cup) granulated sugar, and 1/8 tsp fine sea salt in a heavy-bottomed saucepan over medium-low heat. Stir occasionally until the mixture reaches 71°C (160°F) and small bubbles form around the pan edges, about 8-10 minutes; do not bring to a rolling boil.
Temper egg yolks
While the dairy heats, whisk 6 large pasteurized egg yolks and the remaining 65g (1/3 cup) granulated sugar in a medium heatproof glass bowl for 2 minutes until the mixture is pale lemon-yellow, thick, and leaves a slow ribbon when the whisk is lifted. Slowly pour 120ml (1/2 cup) of the warm dairy mixture into the yolk mixture in a thin stream, whisking constantly to avoid curdling the eggs.
Cook custard base
Pour the tempered egg yolk mixture back into the saucepan with the remaining warm dairy, stirring constantly with a heatproof silicone spatula over medium-low heat. Cook for 5-7 minutes until the custard reaches 79°C (175°F) and thickens enough to coat the back of the spatula; a line drawn with your finger across the coated spatula will hold its shape without running.
Strain and chill base
Pour the hot custard through a fine-mesh stainless steel sieve into a clean, airtight glass container to remove any tiny curdled egg bits. Stir in 15ml (1 tbsp) pure vanilla extract, then press a piece of plastic wrap directly onto the surface of the custard to prevent a skin from forming. Refrigerate for a minimum of 4 hours (or up to 24 hours) until the base is completely chilled to 4°C (40°F) or colder.
Churn frozen custard
Pour the fully chilled custard base into a pre-frozen ice cream maker bowl and churn on the machine’s slowest setting for 15-20 minutes, until the custard reaches a thick, soft-serve consistency similar to stiff whipped cream. The slow churn limits air incorporation (called overrun) to create the dense, silky texture signature to Wisconsin custard.
Harden and serve
Transfer the churned soft custard to a lidded freezer-safe container, pressing a piece of parchment paper directly onto the custard surface to prevent ice crystal formation. Freeze for 30-45 minutes until the custard is firm enough to scoop but still dense and slow-melting; avoid freezing for longer than 2 hours before serving, as extended freezing will make the custard overly hard and lose its signature smooth texture.
Tips
2.For authentic Wisconsin texture, keep churning overrun (air mixed into the base) below 20%—this is far less than standard ice cream’s 30-50% overrun, creating the dense, slow-melting bite that custard fans love.
3.If small curdles form while cooking the custard base, immediately move the pan to an ice water bath, blend for 10 seconds with an immersion blender, then strain to rescue the base instead of starting over.
OMG, this tastes exactly like the frozen custard I got every summer at Wisconsin state fairs growing up! My kids went absolutely nuts for it, I had to hide the last scoop so my husband didn't eat it all before I got a second serving. 10/10, will be making this for every backyard cookout this summer.
Game changer! I've tried so many copycat frozen custard recipes over the years and they always turn out icy or too eggy, but this one is perfectly smooth and rich. The 4 hour chill time felt long but it was so worth it, I didn't skip a single step.
Made this for my son's 10th birthday party over the weekend and it was a total hit! I set out hot fudge, sprinkles, crushed Oreos, and maraschino cherries for a sundae bar and every single kid (and parent!) asked for the recipe. SO good, way better than the store bought stuff we usually get.
Wait, is there a way to make this without an ice cream maker? I don't have one and I've been dying to make proper custard for my grandkids when they visit next month. I tried a no-churn version once and it just wasn't the same texture.
I was so intimidated to make this because I've messed up custard bases before (scrambled eggs galore, ugh) but the instructions were super clear and easy to follow! I took it slow tempering the eggs and it came out perfect on the first try. My roommates are already begging me to make it again next weekend.
Brought this to our neighborhood potluck last week and people were lined up for seconds! I did a little twist with a fresh raspberry swirl and it complemented the rich vanilla custard so well. Will absolutely be adding this to my regular potluck rotation all summer long.
Wait, this is labeled medium difficulty—what makes it medium vs easy? I'm a pretty new baker and I don't want to waste a bunch of ingredients if it's too fussy for a beginner.
As someone who has to eat gluten free, it's so nice to have a decadent dessert recipe that doesn't require any weird specialty flour substitutes! This is naturally GF and so rich I don't even need a big serving to satisfy my sweet tooth. My whole family loved it, even the ones who turn their nose up at GF food.
I grew up just outside Milwaukee and I've been chasing that perfect frozen custard flavor since I moved out west 10 years ago. This is dead on—thick, creamy, not too sweet, with that distinct eggy richness that makes frozen custard different from regular ice cream. I mixed in a little chocolate malt powder during churning and it tasted just like the concretes I got as a kid.
My kids are super picky when it comes to frozen treats—they usually only want the neon colored popsicles from the grocery store, but they devoured this! I let them help stir the base (with close supervision, obviously, so we didn't have any scrambled egg incidents) and they thought it was the coolest thing ever making "ice cream" from scratch.
I was worried the 4 hour chill time would make this a pain for meal prep, but I made the base the night before I wanted to serve it, left it in the fridge overnight, and churned it right before my book club came over. It was the perfect easy dessert to serve with coffee, everyone asked for seconds.
This was really tasty, but I wish the recipe specified what kind of salt to use! I grabbed regular table salt instead of kosher salt when I was making the base and it came out a touch saltier than I prefer, totally my bad. It still had that perfect smooth custard texture, I'll just cut the salt amount in half next time I whip up a batch.
