Ice Cream Base
- 2 cups heavy cream
- 1 cup whole milk
- ¾ cup granulated sugar
- 4 large egg yolks
- 1 teaspoon vanilla extract
- ½ teaspoon black walnut extract optional, but enhances flavor
- Pinch of salt
Black Walnuts
- ¾ cup black walnuts chopped
- 1 tablespoon butter for toasting the walnuts
Step 1: Toast the Black Walnuts
Preheat your oven to 350°F (175°C).
Spread the chopped black walnuts on a baking sheet.
Toast for 5–7 minutes, stirring occasionally until fragrant.
Remove from the oven and toss with 1 tablespoon of melted butter for extra richness. Set aside to cool.
Step 2: Prepare the Custard Base
In a medium saucepan, heat the heavy cream, whole milk, and half of the sugar over medium heat. Stir occasionally until the mixture begins to steam (do not let it boil).
In a separate bowl, whisk the egg yolks and remaining sugar until pale and slightly thickened.
Slowly temper the eggs by adding a small amount of the hot cream mixture while whisking constantly.
Pour the tempered egg mixture back into the saucepan and cook over low heat, stirring continuously until it thickens enough to coat the back of a spoon (170–175°F / 77–80°C).
Step 3: Chill the Custard
Remove from heat and stir in vanilla extract, black walnut extract (if using), and a pinch of salt.
Strain the custard through a fine-mesh sieve into a clean bowl to remove any cooked egg bits.
Let it cool at room temperature for 30 minutes, then cover and refrigerate for at least 4 hours (or overnight).
Step 4: Churn the Ice Cream
Once chilled, pour the custard into an ice cream maker and churn according to the manufacturer’s instructions (usually 20–25 minutes).
In the last few minutes of churning, add the toasted black walnuts and allow them to mix evenly.
Step 5: Freeze & Serve
Transfer the churned ice cream to an airtight container and smooth the top with a spatula.
Freeze for at least 2 hours to firm up before serving.

- No Ice Cream Maker? You can make a no-churn version by whipping 2 cups of heavy cream until soft peaks form, then folding it into 1 can of sweetened condensed milk along with the black walnuts. Freeze for 6 hours before serving.
- Nut Allergies? Substitute pecans or regular walnuts for a milder flavor.
- Storage Tip: Store in an airtight container in the freezer for up to 2 weeks to maintain freshness.
