This custard ice cream delivers the silky smooth texture you love with a fraction of the fat. The secret lies in using egg whites and low-fat dairy to create that classic rich mouthfeel.
What emerges from your ice cream maker is a creamy, dreamy treat that satisfies your sweet tooth without the guilt. It proves that indulgence doesn’t require compromise.
Ingredients for Low Fat Custard Ice Cream
Simple ingredients create a creamy, dreamy low-fat custard ice cream with rich flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Low-Fat Milk 🥛 | 2 cups | 2% or skim preferred |
| Heavy Cream 🥛 | ½ cup | Light cream works too |
| Egg Whites 🥚 | 4 whole | Large eggs, room temperature |
| Granulated Sugar 🍚 | ¾ cup | Or substitute coconut sugar |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla for best flavor |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Cornstarch 🌾 | 1 tbsp | For thickening custard |
| Non-Fat Greek Yogurt 🥛 | ½ cup | Adds creaminess without fat |
| Vanilla Bean 🌿 | 1 whole | Scraped seeds only |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed brightens flavor |
The dairy is key here. Low-fat milk keeps things light while the heavy cream (just a touch) adds that luxurious mouthfeel. I always grab Organic Valley or Horizon from Whole Foods—their quality is consistent. Egg whites replace yolks for that silky texture without the fat. Make sure they’re fresh and at room temp for best results (cold ones won’t whip up right).
No heavy cream? Full-fat coconut milk works in a pinch, though the flavor changes slightly. Out of egg whites? Aquafaba (chickpea brine) can substitute, but adjust sweetness to taste. The cornstarch thickens without adding richness—arrowroot powder is a good swap if you’ve got it. For extra flavor, add a scraped vanilla bean along with the extract (worth the splurge).
The custard base keeps in the fridge for 2 days before churning. Once churned, ice cream is best fresh but holds for 1 week in an airtight container. Press plastic wrap directly on the surface to prevent ice crystals (don’t skip this part).

Step-by-Step Instructions for Low Fat Custard Ice Cream
Here’s how I create this creamy delight without the usual guilt.
Step 1: Infuse and Heat the Dairy Base
In a medium saucepan, combine the 2 cups Low-Fat Milk and 0.5 cup Heavy Cream. Split the 1 whole Vanilla Bean lengthwise, scrape out the seeds, and add both seeds and pod to the pan.
Heat over medium heat until the mixture just begins to simmer—you’ll see tiny bubbles forming around the edges. Stir occasionally to prevent scorching. Remove from heat, cover, and let steep for 10 minutes to infuse the vanilla flavor.
Step 2: Whisk Egg Whites with Sugar and Cornstarch
While the dairy infuses, whisk the 4 whole Egg Whites, 0.75 cup Granulated Sugar, 1 tbsp Cornstarch, and 0.25 tsp Salt in a large bowl. Whisk vigorously for 2-3 minutes until the mixture turns pale and slightly thickened.
This step is crucial for building the custard’s structure. The cornstarch helps stabilize the egg whites, preventing curdling while ensuring a smooth, velvety texture in the final ice cream.
Step 3: Temper and Thicken the Custard
Slowly pour the warm dairy mixture into the egg white mixture while whisking constantly. This tempering process prevents the egg whites from scrambling. Once fully combined, return the mixture to the saucepan.
Cook over medium-low heat, stirring constantly with a silicone spatula, for 5-7 minutes until the custard thickens enough to coat the back of a spoon. Watch for the mixture to reach 170°F—it should look like a thin pudding.
Step 4: Chill and Finish the Base
Strain the custard through a fine-mesh sieve into a clean bowl to remove the vanilla pod and any potential lumps. Stir in the 2 tsp Vanilla Extract, 0.5 cup Non-Fat Greek Yogurt, and 1 tsp Lemon Juice until fully incorporated.
Press plastic wrap directly onto the surface of the custard to prevent a skin from forming. Refrigerate for at least 4 hours, or preferably overnight, until completely chilled. This cooling step ensures a smooth churn in your ice cream maker.
Step 5: Churn and Freeze to Perfection
Pour the chilled custard into your ice cream maker and churn according to the manufacturer’s instructions, typically 20-25 minutes. The mixture should look like soft-serve when it’s ready.
Transfer to a freezer-safe container and freeze for at least 4 hours until firm. The result is a silky, scoopable ice cream with all the richness but a fraction of the fat. Serve and enjoy your guilt-free treat!
Pro Tips For Making Low Fat Custard Ice Cream
- Temper the Eggs: Slowly whisk a cup of the hot milk mixture into the egg whites before combining everything—this prevents scrambled eggs in your custard. I learned this the hard way after ruining two batches.
- Use Full-Fat Vanilla: Sounds weird, but it works: splash in 1 teaspoon of real vanilla extract, not imitation, to compensate for the lower fat content in the milk.
- Skip the Boil: Heat the milk and cream to just 180°F—any hotter and the proteins can separate, leaving your custard grainy instead of silky.
- Chill Overnight: After churning, let the ice cream sit in the freezer for at least 4 hours or overnight. It firms up properly and the flavors meld—your future self will thank you.
Best Sauces and Condiments for This Recipe
Fruit Compote Drizzle
A warm berry compote made from 1 cup mixed berries and 2 tbsp sugar simmered for 10 minutes adds a bright, tangy contrast. I love using frozen berries for convenience—they release pectin naturally as they cook.
Chocolate Magic Shell
Make a lighter magic shell by melting ½ cup dark chocolate chips with 1 tsp coconut oil. Drizzle over your bowl and watch it harden instantly. The dark chocolate adds richness without excess fat.
Citrus Zest Garnish
Finely grate 1 tsp orange or lemon zest over each serving for a pop of color and aroma. It enhances the vanilla notes beautifully. I always use organic citrus to avoid wax coatings.
Honey and Nut Topping
Toast ¼ cup chopped almonds and drizzle with 1 tbsp warm honey for crunch and sweetness. The honey’s viscosity makes it cling perfectly to each scoop. 💛
Caramelized Banana Slices
Quickly sauté 2 sliced bananas in 1 tsp butter until golden. The natural sweetness caramelizes beautifully, adding warmth to the cool ice cream.
Mint-Infused Syrup
Simmer ½ cup water, ½ cup sugar, and 10 fresh mint leaves for 5 minutes. Strain and drizzle lightly for a refreshing herbal note that cuts through the creaminess. 🌿

Frequently Asked Questions
Can I use all milk instead of cream?
Yes, but the texture will be less creamy. Use 2.5 cups low-fat milk and add 1 tbsp cornstarch to compensate. The result will be lighter but still delicious.
Why use egg whites instead of whole eggs?
Egg whites provide structure without the fat from yolks. They create the same silky texture while keeping the recipe light. This swap cuts calories but keeps the custard base rich.
How do I prevent ice crystals from forming?
Press plastic wrap directly on the custard surface before chilling. Also, don’t skip the 4-hour freeze after churning. These steps lock in smoothness.
Can I make this dairy-free?
Substitute coconut milk for the dairy and use aquafaba instead of egg whites. The flavor will differ slightly but remains creamy.
