Whether you’re hosting guests or just want a make-ahead treat for the week, this is a reliable, elegant option. You only need a handful of ingredients and a few simple steps to get it right.
Keto Vanilla Panna Cotta – A Silky, Low-Carb Classic
Ingredients
- Unflavored powdered gelatin – sets the panna cotta
- Heavy cream – base for rich, silky texture
- Unsweetened almond milk (or other unsweetened keto-friendly milk like macadamia) – lightens the cream
- Granulated erythritol or allulose (or a blend) – low-carb sweetener
- Pure vanilla extract (or vanilla bean paste) – main flavor
- Pinch of fine sea salt – enhances flavor
- Optional garnish: fresh raspberries or blackberries, sugar-free berry sauce, shaved dark chocolate (90%+), or toasted nuts
Instructions
- Bloom the gelatin. In a small bowl, sprinkle 2 teaspoons unflavored gelatin over 3 tablespoons cold water. Let it sit for 5–10 minutes until it swells and looks spongy.
- Warm the dairy base. In a saucepan, combine 1 1/2 cups heavy cream and 1 cup unsweetened almond milk. Add 1/3 cup granulated erythritol or allulose and a small pinch of salt. Warm over medium-low heat, stirring, until the sweetener dissolves and the mixture is hot but not boiling.
- Add vanilla. Remove from heat and stir in 2 teaspoons pure vanilla extract (or 1 teaspoon vanilla bean paste for specks and deeper flavor).
- Melt the gelatin. Add the bloomed gelatin to the warm dairy. Whisk gently until fully dissolved. If needed, return the pot to very low heat and stir just until smooth. Do not simmer.
- Taste and adjust. Taste the mixture. If you prefer a sweeter panna cotta, add a bit more sweetener and stir to dissolve. Balance with a tiny extra pinch of salt if needed.
- Strain for silkiness. For the smoothest result, pour the mixture through a fine-mesh sieve into a large measuring cup with a spout. This catches any undissolved bits.
- Portion and chill. Divide into 6 small ramekins, glasses, or jars. Let them cool at room temperature for 15–20 minutes, then cover and refrigerate at least 4 hours, preferably overnight, until set.
- Serve and garnish. Enjoy straight from the cups, or unmold by dipping the ramekin bottoms briefly in warm water and inverting onto plates. Garnish with a few berries, a drizzle of sugar-free sauce, or a sprinkle of shaved dark chocolate.
Why This Recipe Works
Panna cotta is naturally a great fit for keto because it relies on cream and gelatin—not flour or starch—for body. The sweetness comes from a low-carb sweetener, so you keep the flavor and lose the sugar spike.
Vanilla shines through in a clean, balanced way, and the texture is silky from the combination of heavy cream and a touch of almond milk. The method is straightforward: bloom the gelatin, warm the dairy, sweeten and flavor, then chill. With a little patience, you get a restaurant-worthy dessert that’s easy to customize.

Storage Instructions
- Refrigerator: Keep covered in the fridge for up to 4–5 days. They may firm up a touch more after the first day.
- Freezer: Not ideal.
Freezing can cause a grainy texture as gelatin weeps when thawed.
- Make-ahead: This dessert is perfect for prepping the day before an event. Add fresh garnishes right before serving.
Why This is Good for You
This panna cotta keeps carbs low by swapping sugar for a zero- or low-calorie sweetener. Heavy cream and almond milk provide satisfying fats that help keep you fuller longer.
Gelatin adds a bit of protein and may support skin and joint health. With portion control, it fits into a keto lifestyle without feeling like a compromise. You get a dessert that’s indulgent but steady on blood sugar.
Pitfalls to Watch Out For
- Boiling the mixture: High heat can dull the vanilla flavor and break down gelatin.
Warm gently and avoid simmering.
- Undissolved gelatin: If you see grains or strings, it wasn’t fully melted. Strain and, if necessary, rewarm very gently until smooth.
- Too much sweetener: Some sugar alcohols can crystallize or leave a cooling aftertaste. Allulose tends to stay smooth; blends can help balance flavor.
- Skipping the bloom: Adding dry gelatin straight to hot liquid leads to clumps.
Always bloom in cold water first.
- Impatient chilling: It needs several hours to set. Rushing leads to a soft or uneven texture.
Recipe Variations
- Vanilla Bean Panna Cotta: Use 1 vanilla bean. Split, scrape seeds into the dairy, and add the pod while heating.
Remove the pod before adding gelatin.
- Coconut-Vanilla: Swap almond milk for unsweetened coconut milk (carton or canned light). Expect a gentle coconut note and slightly firmer set if using canned.
- Coffee-Vanilla: Stir in 1–2 teaspoons instant espresso powder to the warm dairy for a mocha vibe.
- Lemon-Vanilla: Add 1–2 teaspoons finely grated lemon zest and a teaspoon of lemon juice for brightness. Balance with a bit more sweetener if needed.
- Chocolate Ribbon: Melt 1 ounce of 90% dark chocolate with 2 tablespoons cream.
Swirl a spoonful into each cup before chilling.
- Berry Layer: Spoon a thin layer of cooled, sugar-free berry compote into the bottom of cups, then pour panna cotta over and chill.
FAQ
Can I use agar instead of gelatin?
Agar can work, but it sets firmer and less creamy. If you try it, use about half the amount by volume, dissolve it by simmering in the almond milk for a few minutes, then combine with cream and sweetener. Expect a slightly different, more brittle texture.
Which sweetener tastes best?
Allulose offers the smoothest finish with no crystallizing and a clean taste.
Erythritol works but can feel cooling. A blend of allulose and a touch of monk fruit or stevia often delivers a balanced, natural sweetness.
How do I fix grainy panna cotta?
If it hasn’t set yet, gently rewarm the mixture and whisk until smooth, then strain and rechill. If it’s already set and grainy, it’s hard to fully fix, but you can reheat on low, whisk, strain, and reset with a tiny splash of extra cream if needed.
Can I make it dairy-free?
Yes.
Use full-fat canned coconut milk plus unsweetened coconut milk or almond milk to reach the same total volume. The flavor will lean coconut, but it’s delicious and still keto-friendly. Adjust sweetener to taste.
How firm should panna cotta be?
It should quiver when you jiggle the cup and yield easily to a spoon.
If it’s rubbery, you used too much gelatin. If it’s too soft, it may need more chilling time or a small increase in gelatin next time.
How do I unmold it cleanly?
Run a thin knife around the edge, then dip the ramekin bottom in warm water for 5–10 seconds. Invert onto a plate and give a gentle shake.
If it sticks, repeat the warm-water dip briefly.
What size servings are best for keto?
Small portions are ideal. Six servings from this recipe usually hit a nice balance of satisfaction and macros. Add fresh berries sparingly if you like a tart contrast.
