This recipe is about as simple as it gets. If you can measure and stir, you can make this ice cream. No tempering eggs, no complicated custards. Just mix, chill, and churn (or not!).
🛒 Ingredients
Makes approximately 1 quart (4–6 servings)
-
2 cups heavy cream – The base of our ice cream; high fat content ensures creaminess and keto compliance.
-
1/2 cup powdered allulose or powdered erythritol – Powdered sweeteners dissolve better, preventing a gritty texture. Allulose is preferred for its ability to stay soft when frozen.
-
2 teaspoons pure vanilla extract – Adds warmth and depth. Avoid imitation vanilla, which can taste artificial.
-
1/8 teaspoon fine sea salt – Balances sweetness and enhances flavor. Don’t skip it!
Optional Flavor Variations (Still 4 Ingredients!)
-
Chocolate: Add 1/4 cup unsweetened cocoa powder (adjust sweetener to taste).
-
Strawberry: Puree 1 cup fresh or frozen strawberries and swirl in before freezing.
-
Mint Chip: Add 1/2 teaspoon peppermint extract and 2 tablespoons sugar-free chocolate chips.
-
Coffee: Steep 2 tablespoons finely ground coffee in warm cream for 30 minutes, then strain.
🥣 Equipment Needed
-
Large mixing bowl
-
Whisk or hand mixer
-
Measuring cups and spoons
-
Loaf pan or freezer-safe container with lid
-
Ice cream maker (optional but recommended)
-
Parchment paper (optional, for easy removal)
👩🍳 Instructions
Step 1: Chill Your Bowl (Optional But Helpful)
If using an ice cream maker, place the freezer bowl in the freezer at least 24 hours in advance. If making by hand, you can skip this—but a cold bowl helps the cream whip faster.
Step 2: Mix Dry Ingredients
In a small bowl, combine the powdered sweetener and salt. Stir to break up any clumps. Powdered sweeteners are crucial here; granulated erythritol will leave your ice cream icy and gritty.
Step 3: Whip the Cream
Pour the heavy cream into a large mixing bowl. Using a hand mixer or stand mixer with the whisk attachment, beat on medium-high speed until soft peaks form—about 2–3 minutes. You want the cream to thicken and hold its shape, but stop before it turns into butter.
Pro tip: If you’re new to whipping cream, chill your cream and bowl beforehand for best results.
Step 4: Add Sweetener and Vanilla
Gradually sprinkle in the sweetener mixture while continuing to beat on low speed. Add the vanilla extract. Increase speed to medium and beat until stiff peaks form—another 1–2 minutes. The mixture should be thick, glossy, and hold a peak when you lift the beaters.
Step 5: Taste and Adjust
This is your moment. Give the whipped cream a taste. Adjust sweetness or vanilla if needed. Remember: freezing dulls sweetness, so aim for slightly sweeter than you’d like at this stage.
Step 6: Freeze
Now you have two paths:
With an Ice Cream Maker:
Transfer the whipped mixture to your ice cream maker and churn according to the manufacturer’s instructions—usually 20–25 minutes. It will resemble soft-serve. Scoop into a freezer-safe container, press a piece of parchment paper directly against the surface, cover, and freeze for at least 4 hours until firm.
Without an Ice Cream Maker:
Spoon the whipped cream directly into a loaf pan or freezer container. Smooth the top, press parchment against the surface, and cover tightly. Freeze for 4–6 hours, checking at the 2-hour mark to stir vigorously with a fork. This breaks up ice crystals and improves texture. Repeat once more before fully freezing.
Step 7: Serve
Let the ice cream sit at room temperature for 5–10 minutes before scooping. This softens it to the perfect creamy consistency. Use a sturdy ice cream scoop dipped in warm water for clean scoops.
❄️ Storage
Store in an airtight container in the freezer for up to 2 months. To prevent ice crystals, always press plastic wrap or parchment directly onto the surface before sealing.

💡 Tips for Perfect Keto Ice Cream Every Time
-
Powder your sweetener. Granular erythritol will never fully dissolve in cold cream. Pulse it in a clean coffee grinder or buy it pre-powdered.
-
Don’t overwhip. If your cream turns grainy and separates, you’ve made butter. Stop at stiff peaks.
-
Temperature matters. Let the ice cream sit out before scooping. Keto ice cream freezes harder than sugar-sweetened ice cream, but patience solves this.
-
Alcohol helps. A tablespoon of vodka or keto-friendly liquor can lower the freezing point, making scooping easier. Add it with the vanilla.
-
Add-ins at the end. If adding chocolate chips, nuts, or berries, fold them in just before freezing to keep them evenly distributed.
❓ Frequently Asked Questions
Can I use half-and-half or milk?
Heavy cream is best for texture and keto macros. Lower-fat dairy will result in icy, crystallized ice cream. Stick with cream.
What’s the best sweetener?
Allulose creates the softest ice cream because it doesn’t recrystallize when frozen. Erythritol works but may harden more. Avoid liquid sweeteners—they add too much water.
Is this dairy-free friendly?
You can substitute full-fat coconut cream, but the texture will be slightly different. Omit the vanilla if using unflavored coconut cream.
Why is my ice cream rock hard?
Keto ice cream lacks sugar, which acts as an antifreeze in traditional recipes. Let it sit out for 10–15 minutes before serving, or add 1 tablespoon of vodka or glycerin to the base.
Can I double this recipe?
Absolutely. Just ensure your mixer bowl is large enough to accommodate the whipped cream expansion.
🍨 Why This Recipe Works
Traditional ice cream relies on sugar, eggs, and careful custard-making to achieve a creamy texture. This keto version skips the fuss and uses pure heavy cream whipped to incorporate air, then frozen. The high fat content keeps the ice cream smooth, while the powdered sweetener dissolves completely to avoid grit.
By whipping the cream first, we’re essentially churning air into the base, mimicking the action of an ice cream maker. The result is a scoopable, luxurious dessert that rivals any premium brand—without the sugar crash.
🌿 Final Thoughts
This Homemade 4-Ingredient Keto Ice Cream is proof that eating low-carb doesn’t mean sacrificing joy. It’s a blank canvas for endless flavor variations, ready in minutes, and made with ingredients you can pronounce.
Whether you’re strict keto, low-carb curious, or simply someone who appreciates good food made simply, this recipe belongs in your freezer. One bite of that cool, velvety cream, and you’ll wonder why you ever bought the carton.
