Oatmeal Raisin Ice Cream: Creamy Frozen Dessert
You may be tempted to boil the custard quickly to save time. This mistake produces a grainy texture and scrambled eggs in your oatmeal raisin ice cream. Overheating the mixture breaks the emulsion, leaving you with lumps instead of a smooth base.
This dessert is a frozen custard made with heavy cream, whole milk, and egg yolks. When made correctly, it is silky and thick with a savoury depth from the toasted oats. The raisins remain plump and sweet, providing a contrast to the cinnamon-infused cream.
The temperature of the custard decides the final result. You must cook the mixture until it reaches 82°C (180°F) without boiling. Straining the custard through a fine-mesh sieve ensures no lumps remain. Chilling the base in the refrigerator for 30 minutes prevents ice crystals from forming during the churn.

Recipe cardIngredients
Instructions
-
Toast the oats
Toast the rolled oats in a dry skillet over medium heat for 3–4 minutes. Stir them until they are lightly golden and fragrant. Set them aside to cool so they remain crisp in the ice cream.
-
Soak the raisins
Rinse the raisins and place them in a small bowl. Dissolve 15 g of granulated sugar in 60 ml sweetened grape juice and pour it over the fruit. Let them stand for 15 minutes, stirring occasionally, to plump the raisins.
-
Heat the cream
Combine the heavy cream, whole milk and ground cinnamon in a medium saucepan. Heat over medium for around 5 minutes until just before simmering. Remove the pan from the heat immediately to prevent boiling.
-
Whisk the yolks
Whisk the egg yolks with the light brown sugar in a heat-proof bowl. Beat the mixture until it is pale, thick and smooth. This ensures the sugar dissolves and the custard emulsifies correctly.
-
Temper the custard
Slowly pour a quarter of the hot cream into the yolks while whisking vigorously. Return the whole mixture to the saucepan over low heat. Stir constantly until it reaches 82°C (180°F), which allows it to thicken without curdling.
-
Strain and chill
Strain the custard through a fine-mesh sieve into a clean bowl to discard any lumps. Let it sit at room temperature for 15 minutes, then refrigerate for 30 minutes. Chilling prevents the ice cream from forming crystals.
-
Churn the base
Pour the cold custard into your ice cream maker and churn for 20 minutes. Gently fold in the soaked raisins and toasted oats during the final 5 minutes. This keeps the mix-ins evenly distributed.
-
Freeze the ice cream
Transfer the thickened mixture to a freezer-proof container and seal it tightly. Freeze for 4 hours before serving. This sets the texture for a smooth, creamy scoop.
Watch the custard temperature closely. If you bring it to a boil, the eggs will scramble and the texture will become grainy. Ensure the custard is thoroughly cold before churning; a hot base causes the fat to separate and creates large ice crystals.
What goes wrong and why
Ice crystals form if you churn custard that is too hot. This happens because the fat does not emulsify correctly at high temperatures. Watch the temperature of your base; ensure it reaches 82°C (180°F) during cooking but is thoroughly chilled in the refrigerator before you begin the churning process.
What to serve with it
Place scoops in a snow-white bowl and top with a drizzle of toasted oat crumb and ground cinnamon. For a more complex presentation, layer the ice cream in a parfait with caramel-soaked raisins and oat-flavoured whipped cream, or serve it in a clear glass with ground nutmeg.
Storing and reheating
Keep the ice cream in a sealed container in the freezer for up to 2 weeks. Do not leave the dairy base at room temperature for more than 2 hours. Let the frozen container sit for 10 to 15 minutes on the counter before scooping to ensure a silky texture.

Questions people ask
Is oatmeal raisin the healthiest cookie?
No. While oats provide some fibre, these cookies usually contain high amounts of refined sugar and fats. They are a treat rather than a health food, much like the rich custard used in this ice cream recipe.
What to eat when I'm craving ice cream?
Choose a homemade version like this oatmeal raisin ice cream. Making it yourself allows you to control the quality of the dairy and the amount of sugar used compared to store-bought options.
Does oatmeal ice cream exist?
Yes. It is made by infusing a custard base with toasted oats or folding in cooked grains. This version uses toasted rolled oats to provide a nutty flavour and a distinct texture within the cream.
