A creamy lemon posset is pure comfort in dessert form. It feels elegant, yet it is one of the easiest sweets you can make at home. I love recipes like this because they look fancy on the table, but they do not ask much from the cook. That makes this dessert perfect for family meals, quiet evenings, and special gatherings alike.
This version uses 2 cups heavy whipping cream (36% milk fat or higher), 2/3 cup granulated sugar, and 5 tablespoons fresh lemon juice from about 3 lemons. Then, for a pretty finish, you can add whipped cream, lemon slices, fresh berries, or mint leaves. If you want a fun twist, you can even serve the lemon posset in 5 to 6 lemons, halved and hollowed out, instead of ramekins. As a result, you get a dessert that tastes rich and bright at the same time, with a smooth, silky texture and a fresh citrus flavor.
The method is simple, too. First, if you are using lemon cups, you hollow out the lemons and strain the juice. Then you heat the cream and sugar until the sugar dissolves and the mixture comes to a boil. After that, you keep it at a steady medium boil for 5 minutes, stir in the lemon juice, and let it cool. Finally, you strain, pour, and chill until set. In short, this Creamy 3-Ingredient Lemon Posset Dessert takes about 8 minutes of prep, 7 minutes of cooking, and 2 hours of chilling and cooling, for a total time of 2 hours 30 minutes. It serves 10 and comes in at about 215 kcal per serving.
This dessert is especially lovely for warm-weather dinners, spring holidays, brunch tables, and potlucks. However, it is just as welcome on a chilly night when you want something light, creamy, and refreshing after a big meal.

Heavy Whipping Cream Tips
For the best lemon posset, choose heavy whipping cream with at least 36% milk fat. That matters because the dessert sets by thickening the cream as it cooks, so a lower-fat cream may not firm up as well. Also, make sure the cream is fresh and not near its expiration date. If you want the smoothest result, use a clean saucepan and stir often while heating so the cream does not scorch. In addition, avoid using half-and-half or milk, since they do not give the same silky finish.
Options for Substitutions
- Use Meyer lemons if you want a slightly sweeter, less sharp citrus flavor.
- Swap granulated sugar for caster sugar if you want it to dissolve a little faster.
- Top with raspberries or blueberries instead of mixed berries for a simple garnish.
- Use orange zest as a garnish if you want a softer citrus note on top.
- Serve in small dessert glasses if you do not want to use ramekins or hollowed lemons.
- Add a few fresh thyme leaves or mint leaves for a light herbal finish.
Watch Out for These Mistakes
One common mistake is boiling too hard for too long. You do want a steady medium boil, because that helps the cream thicken. However, if it boils too aggressively, the mixture may reduce too much or scorch on the bottom. Therefore, keep an eye on the heat and stir now and then.
Another issue is adding the lemon juice too early. The cream needs time to cook first. After that, stir in the lemon juice off the heat. If you add it before the cream is ready, the texture may not set as well. So, follow the order closely.
Also, do not pour the mixture into layers that are too deep. The recipe works best when each portion is about 3/4 inch deep. If the layer is too thick, it may stay loose in the center. For that reason, use enough ramekins or lemon cups so the filling is spread out.
Finally, be careful with storage. Once the posset sets, cover it so it does not pick up fridge smells. Even then, it is best within 3 days. After that, a little liquid may collect on top. If that happens, just drain it off before serving. Also, do not freeze it, because freezing can make it grainy or icy.
What to Serve With Creamy 3-Ingredient Lemon Posset Dessert?
This lemon posset pairs well with light foods that do not overpower its bright flavor. For a nice dessert table, serve it with buttery shortbread cookies, crisp almond biscotti, a fresh berry salad, or a small slice of pound cake. Likewise, a cup of hot tea or coffee works well, because the warm drink balances the cool, creamy dessert. If you are serving guests, a simple plate with a few fresh berries and mint makes the whole meal feel polished without much effort.
Storage Instructions
Store: Keep the lemon posset covered in the refrigerator for up to 3 days. Use plastic wrap or a tight lid so it does not absorb other fridge odors. If a little liquid forms on top after a few days, carefully drain it off before serving.
Freeze: Do not freeze lemon posset. Freezing changes the texture and can make it grainy or icy, so it is best made fresh and kept chilled instead.
Reheat: Lemon posset is meant to be served cold, so reheating is not recommended. If it has been in the fridge for a while and you want it slightly less firm, let it sit at room temperature for 5 to 10 minutes before serving. Do not use the stovetop or microwave to warm it, since that can break the texture.

Step-by-Step Instructions
Step 1: Prep the Lemons or Ramekins
If you want to serve the posset in lemon cups, cut the lemons in half lengthwise and scoop out the pulp and membranes, while avoiding the white pith. Then squeeze the pulp, strain the juice, and use it as part of the 5 tablespoons fresh lemon juice. If you prefer, you can skip this step and use ramekins instead.
Step 2: Heat the Cream and Sugar
Combine the heavy whipping cream and granulated sugar in a small saucepan. Stir over medium heat until the sugar dissolves, and then bring the mixture to a boil. Keep stirring so the sugar fully melts and the cream stays smooth.
Step 3: Boil Gently for 5 Minutes
Lower the heat slightly so the mixture does not boil over. Then keep it at a steady medium boil for 5 minutes, stirring occasionally. This step thickens the cream and helps the lemon posset set later, so do not rush it.
Step 4: Add the Lemon Juice and Cool
Remove the pan from the heat and stir in the fresh lemon juice. Then let the mixture cool for 15 minutes. During this time, the acid works with the cream to help the dessert firm up.
Step 5: Strain for a Smooth Texture
Pour the mixture through a fine-mesh sieve into a large spouted measuring cup. This extra step removes any tiny bits and gives the lemon posset a smooth, polished texture. After that, it will be much easier to pour cleanly into small dishes.
Step 6: Pour and Chill
Pour the mixture into ramekins or lemon halves, filling each about 3/4 inch deep. Do not make the layers too deep, because deeper layers may not set well. Then refrigerate for at least 2 hours until fully set.
Step 7: Garnish and Serve
Just before serving, top the lemon posset with whipped cream, berries, lemon slices, or mint. If you used lemon cups, they will look especially pretty on a serving tray. Serve chilled for the best flavor and texture.
