No-Churn Blueberry Ice Cream (No Machine)
To make no-churn blueberry ice cream without a machine, first cook 2 cups of blueberries with a little sugar and lemon into a quick jammy compote, then cool it. Whip 2 cups of cold heavy cream to stiff peaks and gently fold in one 300 mL can of sweetened condensed milk and vanilla — this base freezes soft and scoopable on its own. Swirl the cooled blueberry compote through it, freeze in a loaf pan for at least 6 hours, and scoop. No ice cream maker needed.
Blueberry season and the hottest weeks of summer arrive together, which feels like a hint. This ice cream needs no machine, no custard, and no candy thermometer — just a bowl, a whisk (or hand mixer), and a loaf pan. It’s the easiest way to turn a flat of blueberries into something everyone remembers.
How no-churn works
Real churned ice cream stays soft because a machine whips in air while it freezes. No-churn fakes both jobs with two ingredients:
- Whipped cream folds in the air.
- Sweetened condensed milk keeps it scoopable — its sugar blocks big ice crystals from forming.
Fold them together and you have a base that freezes soft and creamy on its own. Everything else is flavour.
The blueberry swirl
Don’t just fold raw berries in — they freeze into hard little pebbles. Cook them first into a quick compote: berries, a little sugar, a squeeze of lemon, mashed lightly until jammy. Cool it completely (warm compote melts the cream), then swirl it through the base with a knife for ribbons of berry in every scoop.
Tips for the best texture
- Use cold cream straight from the fridge — it whips faster and holds more air.
- Don’t over-fold once the condensed milk goes in; keep it light.
- Press parchment against the surface before freezing to stop ice forming on top.
Make it yours
- Lemon-blueberry: add extra lemon zest to the base.
- Cheesecake: swirl in crumbled graham and a little cream cheese.
- Mixed berry: use raspberries or blackberries, or a garden mix.
Six hours later (or overnight), you’ve got a litre of soft, purple-swirled summer. Scoop it onto cones, into bowls with more fresh berries, or between two cookies for a sandwich.
Frequently asked questions
Why does no-churn ice cream stay scoopable without a machine?
The sweetened condensed milk is the secret. Its sugar lowers the freezing point and stops big ice crystals forming, while the whipped cream folds in air the way churning normally would. Together they give you a soft, scoopable texture straight from the freezer — no machine, no ice crystals.
Can I use frozen blueberries?
Yes. Frozen blueberries make excellent compote — cook them straight from frozen with the sugar and lemon until jammy, then cool completely before swirling in. Just make sure the compote is fully cold, or it will melt the cream base.
How long does it keep?
About 2 weeks at good quality in an airtight container with parchment pressed against the surface. After that it stays safe but gets icier. It's softest in the first week.
