Some days call for homemade ice cream… but not for hauling out special machines or cooking custard over the stove. That’s exactly where this No-Churn Blueberry Swirl Ice Cream shines. It’s a freezer-friendly, no-fuss recipe designed for real home kitchens—just a bowl, a whisk, and a loaf pan.
What makes this version special? The blueberry swirl is reduced just enough to stay vibrant and jammy without turning icy, and the vanilla base is whipped to a mousse-like texture that freezes creamy, not dense. You’ll end up with smooth, scoopable ice cream layered with bold, fruity ribbons that stay beautifully distinct.
Pro tip: Stop whipping the cream when the peaks stand tall but the tips gently curl—overwhipped cream leads to a grainy frozen texture.
Why This Recipe Works (The Science)
No-churn ice cream relies on three key elements:
- Whipped cream = air + structure. When you whip cold cream (35%+ fat), the fat traps air bubbles. That trapped air mimics what an ice cream machine would normally churn in.
- Sweetened condensed milk = sugar + stability. Its high sugar content lowers the freezing point, preventing rock-hard ice crystals.
- Fruit reduction = less water, better texture. Blueberries are about 85% water. Reducing them into a thick swirl evaporates excess moisture, preventing icy patches.
Did you know? Sugar doesn’t just sweeten—it softens frozen desserts. Too little sugar and your ice cream freezes solid; too much and it won’t hold shape.
Ingredients (with Weights & Purpose)
Blueberry Swirl
- Fresh or frozen blueberries — 250 g (2 cups) — flavor + color
- Granulated sugar — 60 g (¼ cup) — sweetness + moisture control
- Lemon juice — 10 g (2 tsp) — balances sweetness, enhances berry flavor
- Cornstarch — 5 g (1 tsp) — thickens, prevents icy swirl
Ice Cream Base
- Heavy cream (35–40% fat), cold — 500 g (2 cups) — structure + air
- Sweetened condensed milk — 395 g (1 standard 14 oz can / 1¼ cups) — sweetness + anti-freeze effect
- Pure vanilla extract — 5 g (1 tsp) — flavor depth
- Fine salt — 1 g (⅛ tsp) — enhances sweetness
Brand note: Use full-fat sweetened condensed milk. Low-fat versions produce icy texture.
Equipment

Step-by-Step Instructions
Step 1: Make the Blueberry Swirl (10–12 minutes)
In a saucepan, combine blueberries, sugar, and lemon juice. Cook over medium heat for 5–7 minutes, stirring occasionally.
Visual cue: Berries should burst and release juice. Mixture looks glossy and loose.
Mix cornstarch with 1 tbsp water; stir into berries. Cook 1–2 more minutes until thick.
Checkpoint: It should coat the back of a spoon and leave a clear line when you drag your finger.
Cool completely (about 30–45 minutes in fridge).
Avoid this: Adding warm compote to cream—it deflates the air.
Step 2: Whip the Cream (3–4 minutes)
In a cold bowl, whip heavy cream on medium speed.
Visual cue progression:
- 1 minute: foamy bubbles
- 2 minutes: soft ripples
- 3–4 minutes: stiff peaks that stand upright but tips gently curl
Checkpoint: When you lift the whisk, peaks should hold shape but not look grainy.
Avoid overwhipping. Grainy texture = butter starting to form.
Step 3: Fold the Base (2–3 minutes)
In a separate bowl, stir condensed milk, vanilla, and salt.
Gently fold whipped cream into condensed milk in 2 additions.
Visual cue: Mixture should look thick, airy, and mousse-like. No visible white streaks.
Step 4: Swirl and Freeze (6–8 hours)
Pour half the mixture into loaf pan. Spoon ⅓ of cooled blueberry compote. Add remaining cream, then dollop remaining compote.
Use a knife to swirl gently.
Visual cue: Distinct purple ribbons—not fully mixed.
Cover tightly (plastic wrap touching surface). Freeze at least 6 hours, ideally overnight.
Serving temperature: Let sit at room temp 5–8 minutes before scooping.
Troubleshooting (Common Failures & Fixes)
Problem: Ice cream is icy.
Likely causes: Swirl too watery; low-fat cream.
Fix: Reduce berries longer; use 35%+ fat cream.
Problem: Base deflated and dense.
Cause: Over-mixing during folding.
Fix: Fold gently; stop when just combined.
Problem: Hard as a rock.
Cause: Too little sugar.
Fix: Don’t reduce condensed milk quantity.
Problem: Swirl sank to bottom.
Cause: Base too loose.
Fix: Whip cream to proper stiff peaks.
Problem: Grainy texture.
Cause: Overwhipped cream.
Fix: Stop at soft-stiff stage.
Problem: Purple base instead of ribbons.
Cause: Over-swirling.
Fix: 3–4 gentle knife passes only.
Substitutions and Variations
Dairy-Free
- Use 500 g chilled coconut cream (solid part only).
- Replace condensed milk with 370 g coconut condensed milk.
Texture will be slightly denser.
Refined Sugar-Free
- Use maple-sweetened condensed milk alternative (tested once—texture softer).
Flavor Variations
- Add 1 tbsp lemon zest to base for brightness.
- Swap blueberries with raspberries (reduce sugar to 50 g).
- Add 50 g crushed biscuits for texture (fold at end).
Scaling Guide
| Pan Size | Cream | Condensed Milk | Blueberries |
|---|---|---|---|
| 6-inch loaf | 350 g | 275 g | 175 g |
| 8-inch loaf | 500 g | 395 g | 250 g |
| Double batch | 1 kg | 790 g | 500 g |
Freeze time increases by 1–2 hours for double batch.
Storage, Make-Ahead & Freezing
- Freezer: Up to 1 month in airtight container.
- Press cling film directly on surface to prevent ice crystals.
- Do not refreeze once fully melted—texture becomes icy.
Make swirl up to 3 days ahead and refrigerate.
Serving Suggestions
- Serve with warm brownies (temperature contrast is lovely).
- Spoon over lemon pound cake.
- Add a drizzle of white chocolate for extra sweetness balance.
Blueberry + vanilla works because acid balances dairy richness.
FAQs
Can I use frozen blueberries?
Yes. No need to thaw—just cook 1–2 minutes longer.
Can I halve the recipe?
Yes. Use a 6-inch loaf pan and freeze 6 hours.
Why didn’t my cream whip?
Cream must be very cold (below 5°C / 41°F).
Can I reduce sugar?
Not recommended. Sugar controls freezing texture.
Can I make this in an OTG?
No baking needed—just freezer.
Notes From My Kitchen (Testing Log)
Batch 1: Didn’t thicken compote enough. Result: icy purple streaks.
Adjustment: Added cornstarch + cooked longer.
Batch 2: Over-swirled. Entire base turned lavender.
Lesson: Less is more.
Batch 3: Slightly overwhipped cream—texture grainy.
Fix: Stop earlier; finish folding by hand.
Batch 4: Tried low-fat cream (30%). Texture firmer, less creamy.
Final choice: 35–40% fat for best mouthfeel.
Batch 5: Added lemon zest to base—bright, fresh finish. Highly recommended.
After testing different sugar levels and swirl thicknesses, this final version balances scoopability, structure, and flavor contrast.
