Method
Whip the vanilla base
- Beat the heavy whipping cream on high until stiff peaks form, about 3–4 minutes, and the mixture holds ridged lines when you lift the beaters. Stop as soon as it’s thick to avoid graininess.
- Gently fold in the sweetened condensed milk and vanilla extract until the mixture is fully combined and smooth, with no streaks remaining. Keep folding slowly so the whipped texture stays airy.
Swirl the red and blue ribbons
- Pour the mixture into a loaf pan and spread it evenly so the surface is level for cleaner marbling.
- Drizzle the strawberry puree over one half and the blueberry puree over the other half, using a light hand to create distinct ribbons.
- Use a knife to swirl the purees through the base in a marbled pattern, making only a few swirls. Avoid overmixing so the colors don’t fully blend.
Freeze until firm
- Cover and freeze for at least 6 hours, or until firm, before scooping. Let it sit 3–5 minutes at room temperature for easier scooping.
Notes
Pro tip: use cold heavy whipping cream and stop whipping right at stiff peaks so the base stays smooth. Store covered in the freezer for up to 2 weeks. Freeze yes—safest within 2 weeks for best texture. For a dairy-light option, use lactose-free heavy cream and lactose-free sweetened condensed milk (flavor and texture will be very similar).
