This homemade Grapenut Ice Cream combines a rich, creamy custard base with the nostalgic crunch of Grapenuts cereal, creating a delightful contrast in every bite. The ice cream is smooth, creamy, and subtly sweet, with the added texture of soft yet crunchy cereal bits. This New England classic is perfect for those who enjoy unique flavors and textures in their ice cream, and it’s easy to make with just a few ingredients!
In a medium saucepan, combine the whole milk, heavy cream, sugar, and salt. Heat over medium, stirring occasionally, until the sugar has dissolved and the mixture is warm but not boiling.
Temper the Eggs
In a separate bowl, whisk the egg yolks. Gradually add a small amount of the warm milk mixture to the eggs while whisking constantly to temper the eggs. Slowly pour in the rest of the warm mixture, continuing to whisk.
Cook the Custard
Return the egg and milk mixture to the saucepan over low heat. Stir constantly with a wooden spoon or heat-resistant spatula until the custard thickens slightly and coats the back of the spoon, about 10-15 minutes.
Strain and Cool the Custard
Remove the saucepan from the heat and strain the custard through a fine-mesh sieve to remove any cooked egg bits. Let the custard cool slightly at room temperature.
Add Grapenuts
Stir in the Grapenuts cereal into the custard. Let the mixture sit for at least 30 minutes in the refrigerator, or up to several hours to allow the cereal to soften and absorb the flavors of the custard.
Churn the Ice Cream
Pour the cooled custard mixture into your ice cream maker and churn according to the manufacturer's instructions, usually for 20-30 minutes.
Freeze the Ice Cream
Transfer the ice cream to an airtight container and freeze for at least 4-6 hours, or until firm enough to scoop.
Serve and Enjoy
When ready to serve, allow the ice cream to sit at room temperature for a few minutes to soften slightly before scooping.Enjoy as is, or top with your favorite additions like caramel sauce or chopped nuts.
Notes
If you don’t have an ice cream maker, you can still make this ice cream by freezing the mixture in an airtight container and stirring every 30 minutes for the first few hours to break up any ice crystals.
If you prefer a sweeter ice cream, feel free to adjust the amount of sugar to your taste.
For a dairy-free version, substitute the milk and cream with coconut or almond milk, and use a plant-based sweetener if desired. The texture will be slightly different but still delicious!
