Old-Fashioned Homemade Vanilla Ice Cream with Jaca
There is nothing more classic than a bowl of old-fashioned homemade vanilla ice cream — a rich, velvety frozen custard churned from just egg yolks, whole milk, heavy cream, and real vanilla, the kind of treat that tastes like summers on the porch and the Fourth of July. A true cooked custard base is what gives it that dense, creamy, ice-cream-parlor texture instead of an icy freezer block, and it is the perfect canvas for our Jaca swap. We replace every bit of the conventional granulated sugar with Jaca (100% pure allulose) at double the amount: 1 cup of granular Jaca in the custard in place of 1/2 cup of sugar — so you get the same rich, creamy vanilla sweetness with no added sugar and no aftertaste. Because allulose is only about 70% as sweet as the sugar we grew up with, doubling it lands the sweetness right where it should be. And here is the best part: allulose has a lower freezing point than sugar, so this ice cream stays soft and scoopable straight from the freezer instead of turning rock-hard. The custard comes together on the stovetop in about 15 minutes, chills until cold, then churns to soft-serve perfection in your ice cream maker — makes about 1 quart, enough for 8 scoops. Adapted from Add a Pinch. This is a Jaca-adjusted healthier version.
Ingredients
- 4 large egg yolks
- 1 cup Jaca (allulose), granular (for the custard — replaces 1/2 cup granulated sugar at the 2x ratio)
- 1 cup whole milk
- 1 cup heavy cream
- 2 teaspoons vanilla extract (or vanilla bean paste)
Sweetener Used
1 cup granular Jaca Allulose
Replaces: 1/2 cup granulated sugar
Instructions
- 1
In a medium saucepan (off the heat), whisk the egg yolks and the 1 cup granular Jaca together until pale yellow and well combined. The Jaca steps in for the sugar here at double the amount, so you get the same rich sweetness with no added sugar.
- 2
In a separate small saucepan, heat the whole milk over medium-low heat until it just begins to simmer. Do not stir.
- 3
Gradually pour the hot milk into the egg-and-Jaca mixture, whisking constantly so the yolks temper smoothly without scrambling.
- 4
Return the combined mixture to medium-low heat and cook, stirring constantly, until it reaches 165°F and thinly coats the back of a spoon — do not let it boil. Remove from the heat immediately.
- 5
For the silkiest texture, strain the custard through a fine-mesh sieve, then pour it into an airtight container and refrigerate until well chilled, ideally to about 65°F or colder (a few hours, or overnight). The colder the custard, the creamier the ice cream.
- 6
Once the custard is cold, stir in the heavy cream and vanilla extract.
- 7
Pour the mixture into your ice cream maker and churn according to the manufacturer's instructions, about 20 to 25 minutes, until it reaches soft-serve consistency. Serve right away for soft ice cream, or transfer to a container and freeze for a few hours for a firmer scoop.
Pro Tips
- Jaca is about 70% as sweet as conventional sugar, which is exactly why we double it — you get the same rich, creamy vanilla sweetness with no added sugar and no aftertaste.
- Bonus: allulose has a lower freezing point than sugar, so this ice cream stays soft and scoopable straight from the freezer instead of turning rock-hard.
- Chill the custard as cold as possible before churning — a cold base churns faster and freezes creamier with fewer ice crystals.
- Temper slowly: add the hot milk to the yolks a little at a time while whisking so you never scramble the eggs.
- With so few ingredients, the vanilla carries the flavor — use a good-quality pure vanilla extract or vanilla bean paste.
- Strain the custard through a fine-mesh sieve before chilling to catch any bits of cooked egg for an ultra-smooth finish.
