Creamy Lemon Posset Recipe Easy 5-Ingredient No-Bake Dessert

“You’re kidding me,” my friend said, eyeing the tiny jars of lemon posset cooling on the counter. Honestly, I was half expecting skepticism; after all, only five ingredients and no baking? It sounded like one of those too-good-to-be-true recipes. But that night, when I first stirred together cream, sugar, and fresh lemon juice, I had this quiet hope that maybe it would work.

The kitchen smelled like a fresh citrus grove, sharp and sweet, with a whisper of vanilla hanging in the background. I’d whipped up this creamy lemon posset after a long day juggling dinner prep (yes, the same day I’d made that creamy garlic butter Tuscan shrimp pasta you might remember from my other recipes). It was a last-minute dessert idea, really—a way to make something feel special without turning on the oven or spending ages.

What surprised me was how quickly the posset set in the fridge, transforming into a silky, tangy pudding that felt like a little indulgence wrapped in simplicity. No fuss, no complicated ingredients, just that bright lemony zing balanced by the richness of cream. The texture was smoother than I expected, almost like a custard but with a fresh kick.

I caught myself making it again the very next week—this time doubling the batch for a casual dinner party. People kept asking for the recipe, a few even calling it their new favorite dessert. What started as a humble, last-ditch effort turned into a small obsession, a little jar of sunshine on a plate that never fails to please. It’s funny how the simplest things can sneak up on you.

So, if you like your desserts creamy, bright, and ridiculously easy, this creamy lemon posset recipe might just be your next go-to. It’s got that perfect balance of tart and sweet, and the best part? No baking required. Just a handful of ingredients, a little patience, and a promise of a dessert that feels special without the stress.

After testing this creamy lemon posset recipe multiple times (and sharing it with friends and family), I can say it’s one of those rare desserts that delivers on flavor, texture, and ease. Here’s why this five-ingredient no-bake dessert stands out from the crowd:

• Quick & Easy: Ready in under 15 minutes of active time, with just a few hours chilling—perfect for busy evenings or when you’re craving something sweet on short notice.

This recipe isn’t just another lemon pudding. The trick is in gently simmering the cream and sugar together to create that silky base, then adding just the right amount of lemon juice for a slight set that’s not too firm. Adding a splash of vanilla gives it a subtle warmth that rounds out the sharpness perfectly. Honestly, after making this, I find myself comparing other lemon desserts to it—and coming up short.

It’s a dessert that manages to feel both indulgent and light, which is no small feat. Plus, if you’re pressed for time but want to impress (maybe following a hearty comfort meal like my creamy cheesy taco pasta), this posset fits the bill beautifully. The no-bake aspect means less heat in the kitchen and more time to enjoy your company or relax.

What Ingredients You Will Need

This creamy lemon posset uses simple, wholesome ingredients to deliver bold flavor and a satisfyingly smooth texture without any fuss. Here’s what you’ll need:

• Heavy Cream (480ml / 2 cups): The base of the posset, providing richness and creaminess. I prefer using full-fat cream from trusted brands like Organic Valley for the best texture.
• Caster Sugar (150g / 3/4 cup): Dissolves easily and sweetens the dessert without grit. Regular granulated sugar works too if that’s what you have.
• Fresh Lemons (about 3 tablespoons juice): The star ingredient for that bright, zesty flavor. Freshly squeezed is a must here—bottled lemon juice just doesn’t cut it.
• Vanilla Extract (1 teaspoon): Adds a subtle warmth and depth. Use pure vanilla extract if possible; it makes a noticeable difference.
• Optional: Lemon Zest (1 teaspoon): For an extra pop of citrus aroma and flavor, especially if your lemons are particularly fragrant.

All these ingredients are common in most kitchens, which is why this recipe feels so accessible. The fresh lemon juice is crucial to get the right tang and to help the posset set properly. If you want to experiment, you can swap the lemon juice for lime juice for a slightly different citrus twist.

For a dairy-free twist, you could try substituting the cream with coconut cream, but keep in mind the texture and flavor will change. Also, if you want to add some crunch, pairing this posset with a simple shortbread or crispy mac and cheese cups on the side makes for a fun contrast.

Equipment Needed

Making creamy lemon posset requires minimal equipment, which is part of what makes it so appealing. Here’s what I use and recommend:

• Medium Saucepan: For gently heating the cream and sugar. A heavy-bottomed pan works best to avoid scorching.
• Whisk: To stir the mixture smoothly and help dissolve the sugar evenly.
• Measuring Cups and Spoons: For accuracy with ingredients, especially the lemon juice and sugar.
• Fine Mesh Sieve (optional): If you want to strain the lemon juice to remove pulp for an ultra-smooth texture.
• Small Serving Jars or Ramekins: For chilling and serving the posset. Clear glass jars add a nice touch for presentation.

If you don’t have a whisk, a fork will do in a pinch, though whisking gives better results. For chilling, make sure your fridge is cool enough (below 40°F / 4°C) to let the posset set properly overnight or for at least 3 hours. I once used mismatched ramekins and noted that wider ones set a little faster but thinner—something to keep in mind if you want a firmer or softer set.

Preparation Method

1. Combine Cream and Sugar: Pour 480ml (2 cups) of heavy cream into a medium saucepan. Add 150g (3/4 cup) caster sugar. Whisk together gently to combine.
2. Heat the Mixture: Place the saucepan over medium heat. Stir continuously with a whisk to dissolve the sugar and prevent sticking. Heat until the mixture just begins to simmer—small bubbles form around the edges but do not let it boil vigorously. This should take about 5-7 minutes.
3. Simmer for 3 Minutes: Once simmering, reduce heat slightly and let the cream and sugar mixture simmer gently for 3 minutes. This step is key to thickening the cream and developing that silky texture.
4. Remove from Heat and Add Flavorings: Take the pan off the heat. Stir in 1 teaspoon vanilla extract and about 3 tablespoons of freshly squeezed lemon juice. If using lemon zest, add 1 teaspoon now. Stir gently but thoroughly. You’ll notice the mixture begins to thicken as the acid from the lemon juice reacts with the cream.
5. Strain the Mixture (Optional): For the smoothest texture, pour the mixture through a fine mesh sieve into a bowl or jug to remove any lemon pulp or clumps.
6. Pour into Serving Dishes: Divide the mixture evenly into small jars or ramekins. Each should hold about 100-120ml (3.5-4 oz). This recipe serves 4-5.
7. Chill and Set: Cover the dishes with cling film or lids and refrigerate for at least 3 hours, preferably overnight. The posset will firm up to a delicate, creamy pudding consistency.
8. Serve: Garnish with fresh berries, mint, or a thin slice of lemon before serving for a pretty presentation.

Quick tip: If your lemon juice is very tart, start with 2 tablespoons and taste before adding more. The balance between creaminess and acidity is what makes this dessert shine. And if you want to try a fun twist, this posset pairs beautifully with a crisp, buttery biscuit or the creamy cheesy taco pasta for a full meal experience that balances richness and zest.

Cooking Tips & Techniques

Some things I picked up after a few attempts with this creamy lemon posset:

• Simmer, Don’t Boil: Letting the cream mixture simmer gently is crucial. A rolling boil can cause the cream to separate or scorch the bottom, ruining that smooth texture.
• Use Fresh Lemon Juice: Bottled juice lacks the acidity and brightness needed to set the posset properly. Fresh juice also adds natural aroma that lifts the entire dessert.
• Patience for Setting: I know it’s tempting, but don’t rush the chilling time. The posset needs those hours in the fridge to develop its signature silky firmness.
• Adjust Sweetness to Taste: Depending on the lemons’ tartness, you may want to tweak the sugar slightly. I once made it with Meyer lemons and reduced sugar by 20g, and it was perfectly balanced.
• Multi-Tasking Friendly: Since this dessert requires no baking and mostly chilling, you can prepare it ahead and focus on the main course—like my sheet pan Italian sausage and peppers.

One lesson learned: stirring continuously while heating prevents sugar from settling and burning. I once skipped this and ended up with a grainy texture—definitely not the silky posset I aimed for. Also, when adding lemon juice, stir gently but don’t overmix; the acid starts setting the cream immediately, and too much agitation can break the texture.

Variations & Adaptations

This creamy lemon posset recipe is pretty flexible. Here are some ideas to switch it up:

• Berry Lemon Posset: Add a handful of fresh raspberries or blueberries on top before chilling for a fruity burst that complements the lemon.
• Lavender-Infused: Steep a teaspoon of dried culinary lavender in the cream while heating, strain before adding lemon juice for a floral twist.
• Dairy-Free Version: Swap heavy cream for full-fat coconut milk (chilled and thickened). The texture will be slightly different but creamy and delicious.
• Spiced Citrus: Add a pinch of ground ginger or cardamom to the cream during heating for a warm spice note.
• Seasonal Adaptation: In warmer months, try substituting lemon juice with fresh blood orange juice for a colorful, tangy variation.

Personally, I once made a lavender lemon posset for a small gathering, and the subtle floral aroma paired beautifully with the tangy lemon—everyone was curious about what made it so special. This dessert also pairs nicely with other creamy dishes, like the creamy lemon pepper chicken pasta if you want to keep the lemon theme going through your meal.

Serving & Storage Suggestions

Creamy lemon posset is best served chilled, straight from the fridge, for that clean, refreshing texture and bright flavor. Here’s how I like to present and store it:

• Serving: Spoon onto small plates or serve directly in ramekins or mini jars. Garnish with fresh mint leaves, a twist of lemon zest, or a few fresh berries for color and contrast.
• Pairing: Goes wonderfully with buttery shortbread, crisp biscuits, or a light fruit salad. It also makes a perfect light finish after rich mains like my creamy crack chicken penne.
• Storage: Keep refrigerated in an airtight container or covered. It will stay fresh for up to 3 days. Avoid freezing as this can affect the creamy texture.
• Reheating: Not recommended. This dessert is best enjoyed cold.
• Flavor Development: The lemon flavor actually brightens a little after a day in the fridge, so making it a day ahead can deepen the taste.
