Oat Milk Ice Cream Recipe With Eggs: Rich Custard Base for Creamy Scoops

There’s a way to make creamy ice cream without dairy, and this custard base proves it. Oat milk brings natural sweetness while eggs create that rich, velvety texture you expect from traditional recipes.

This method transforms simple ingredients into a luscious, scoopable dessert. The key is tempering the eggs properly and chilling the base thoroughly before churning. It ensures smooth results every time.

You’ll end up with ice cream that’s creamy, satisfying, and undeniably indulgent. The oat milk adds a subtle nuttiness that complements classic flavors like vanilla or chocolate.

No special equipment is needed beyond an ice cream maker. The process is straightforward, and the outcome is always impressive.

Ingredients for Oat Milk Ice Cream Recipe with Eggs

Craft this luxurious custard with pantry staples and a few fresh additions for decadent results.

The eggs are critical here. Pasture-raised yolks from Whole Foods or a local farmers market deliver the richest color and flavor. Oat milk quality matters—Oatly Full-Fat or Chobani Extra Creamy have the body needed to mimic dairy. Don’t substitute low-fat versions, as they lack the necessary fat content. The vanilla bean, while optional, adds a depth that extract alone can’t replicate.

No vanilla bean? Double the extract to compensate. For a lighter texture, swap heavy cream for coconut cream, though it adds a subtle tropical note. Maple syrup at half the amount can replace corn syrup if needed. If avoiding dairy entirely (vegan), use coconut-based heavy cream alternatives like Country Crock Plant Cream. Always temper eggs slowly to prevent curdling.

The base must chill 4 hours minimum (overnight is ideal) before churning. Store finished ice cream in an airtight container with parchment pressed directly on the surface to prevent ice crystals. Keeps 1-2 weeks in the freezer, though it’s best enjoyed within 5 days for optimal texture.

Step-by-Step Instructions for Oat Milk Ice Cream With Eggs

Master the custard base technique for velvety-smooth ice cream with a rich, creamy texture.

Step 1: Infuse and Heat the Dairy Mixture

Combine the 2 cups Oat Milk, 0.5 cup Heavy Cream, 0.5 cup Whole Milk, and 1 tbsp Unsalted Butter in a medium saucepan. If using the 1 whole Vanilla Bean, split and scrape the seeds into the mixture, then add the pod as well.

Heat over medium heat until the mixture begins to steam and small bubbles form around the edges—do not boil. Stir occasionally to ensure the Unsalted Butter melts completely and the Vanilla Bean infuses its flavor. This step develops a rich, aromatic base for your custard.

Step 2: Whisk Yolks and Sugar to Ribbon Stage

In a separate bowl, whisk together the 6 whole Large Egg Yolks and 0.75 cup Granulated Sugar until the mixture turns pale yellow and thickens enough to form ribbons when the whisk is lifted. This process incorporates air, which contributes to the final creaminess.

The Large Egg Yolks must be at room temperature to emulsify properly with the sugar. Continue whisking for 2-3 minutes until the mixture lightens in color and texture. This step ensures a smooth, lump-free custard base.

Step 3: Temper the Egg Mixture with Hot Dairy

Slowly pour the hot dairy mixture into the egg yolk and sugar blend while whisking constantly. This tempering process prevents the Large Egg Yolks from scrambling. Add the hot liquid in a thin, steady stream, maintaining continuous motion.

Once fully combined, return the entire mixture to the saucepan and cook over medium-low heat. Stir constantly with a silicone spatula, scraping the bottom and sides of the pan, until the custard thickens enough to coat the back of the spatula—this should take 5-7 minutes.

Step 4: Add Flavorings and Chill Thoroughly

Remove the custard from heat and stir in the 2 tsp Vanilla Extract, 2 tbsp Corn Syrup, and 0.25 tsp Salt. If you used a Vanilla Bean pod, discard it now. The Corn Syrup adds smoothness and prevents ice crystals from forming.

Strain the custard through a fine-mesh sieve into a clean bowl to remove any cooked bits of egg or vanilla pod remnants. Cover with plastic wrap, pressing it directly onto the surface to prevent a skin from forming. Refrigerate for at least 4 hours or overnight until completely chilled.

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 resemble soft-serve ice cream when finished.

Transfer to a freezer-safe container, smooth the top, and press a piece of parchment paper directly on the surface to minimize ice crystals. Freeze for at least 4 hours or until firm. The result will be a rich, creamy ice cream with a velvety texture.

Troubleshooting Great oat milk ice cream recipe with eggs

Grainy Texture Fix

If your ice cream turns out icy, the base likely didn’t chill long enough. I always refrigerate mine for at least 8 hours—overnight is ideal. Adding 1 extra tbsp Corn Syrup helps inhibit crystal formation too. 💡

Scrambled Eggs Issue

Seeing cooked egg bits? You probably added the hot dairy too quickly. Temper by pouring in a thin stream while whisking constantly. If it happens, strain through a fine-mesh sieve to remove bits before chilling.

Too Thin After Churning

This usually means the custard wasn’t thick enough before churning. Cook until it coats the back of a spoon at 170-175°F. Also, ensure your ice cream maker bowl is fully frozen—12 hours minimum in the freezer.

Overly Sweet Result

Cut back on sugar by 2 tbsp next time. Oat milk has natural sweetness, so you may need less. Balance with ¼ tsp extra Salt to enhance other flavors without adding more sugar.

Vanilla Flecks Missing

If using extract instead of bean, add it after straining to prevent evaporation during cooking. For visible specks, stick with 1 whole Vanilla Bean—split, scraped, and simmered with the dairy.

Freezer Burn Prevention

Press plastic wrap directly on the ice cream surface before sealing the container. This blocks air exposure. For long storage, add a layer of parchment paper on top before freezing. ❄️
