Method
Blend and prep
- Blend ripe bananas until completely smooth, then set aside. The puree should be silky with no visible chunks.
Make the custard
- Heat heavy cream and whole milk until steaming. You want small steam wisps, not a rolling boil.
- Slowly whisk the steaming cream mixture into egg yolks beaten with granulated sugar. Keep whisking until the mixture looks smooth and slightly lighter.
- Cook the custard over medium-low heat, stirring constantly, until it reaches 175F. It should thicken enough to coat the back of a spoon.
- Strain the custard, then stir in vanilla extract, salt, and banana puree. The finished base should look uniform and creamy with a banana color.
- Cool completely before chilling. Move to the refrigerator so it firms up evenly for churning.
Churn and freeze
- Refrigerate the custard for 4 hours, then churn in an ice cream maker. Stop when it has the texture of soft-serve.
- Fold in crushed Nilla wafers and frozen banana slices in the last 2 minutes of churning. Stop and look for evenly distributed wafers and visible banana pieces.
- Freeze until scoopable. The ice cream should hold shape in the scoop with a creamy finish.
Notes
For the smoothest banana flavor, use very ripe bananas and blend until completely smooth before adding to the custard. Refrigerate the churned ice cream covered up to 3 days for best scoopability; freeze up to 2 months (thaw 5–10 minutes at room temperature before scooping). For a lighter option, swap half the heavy cream for whole milk, but expect a softer texture.
