🔪 How to Make Keto Blueberry Swirl Ice Cream

Add the heavy cream to a large mixing bowl and whip using a hand mixer to stiff peaks, then set it aside.

In a separate bowl, add in the mascarpone cheese and unsweetened almond milk.

Mix until combined, then add in the allulose and vanilla.

Continue mixing until combined, then mix in the reserved whipped cream in 3 additions.

Pour some of the mixture into an ice cream storage container or glass loaf pan.

Dollop 1/3 of the blueberry sauce over the top.

Using a butter knife, carefully drag it through the dollops, making a swirl pattern.

Repeat the process twice more, then freeze until the ice cream has set before serving.

☑️ Storage Instructions

Store in an airtight container or loaf pan covered tightly for up to 2 weeks. To prevent freezer burn, press plastic wrap directly against the top if not using a lid.

💡 Tips

• Whip the cream until stiff peaks form and stop there so it doesn’t turn grainy.
• Make sure the mascarpone is at room temperature so it blends smoothly.
• Mix the mascarpone and almond milk slowly to avoid lumps.
• Don’t over-swirl or it’ll lose that distinct swirl and turn purple all over.
• You can let it sit for 3 to 5 minutes at room temp for the perfect soft scoop.

🔄 Substitutions and Additions

• Flavors: Try raspberry jam or strawberry sauce instead of blueberry for a flavor switch.

• Chocolate chips: Add sugar-free white chocolate chips for a sweet crunch

• Lemon: A swirl of lemon curd brings in a fresh citrus note

• Extra blueberries: Stir in freeze-dried blueberries for texture and extra berry flavor.

• Nuts: Mix in toasted chopped almonds or pecans for a little crunch.

Why is This Ice Cream Softer Than Most Keto Versions?

The combination of mascarpone and allulose helps it stay creamy and scoopable without freezing solid.

Can I use a different Sweetener Instead of Allulose?

You can, but it may freeze harder or create a slightly icy texture. Allulose works best for this style.

Why Does My Mascarpone Mixture Looks Grainy?

It likely wasn’t fully softened. Make sure it’s at room temperature before mixing.

How Do I Know When it’s Fully Frozen?

It should be firm but still give a little when pressed. Usually 4–6 hours is enough, but overnight is even better if you want sharp swirls.

Can I Skip the Swirl and Mix the Sauce Right In?

You can, but you’ll lose the pretty visual and it may turn the whole thing purple.
