I love making this Lemon Posset because it turns just three simple ingredients into an incredibly smooth and creamy dessert. The bright lemon flavor balances perfectly with the rich cream, creating a silky treat that feels elegant without requiring much effort. I enjoy serving this dessert chilled after dinner because it tastes refreshing, light, and wonderfully satisfying.

Why You’ll Love This Recipe

I appreciate how unbelievably simple this recipe is while still looking and tasting impressive. With only three ingredients and minimal preparation, I can create a dessert that feels luxurious and special. I also love that there is no baking involved, making it perfect for warm days or quick entertaining. Another reason I keep making it is that the texture becomes naturally thick and velvety thanks to the lemon juice reacting with the cream.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

heavy cream
granulated sugar
fresh lemons

Directions

I pour the heavy cream and sugar into a saucepan and place it over medium heat.
I stir the mixture gently until the sugar completely dissolves.
Once the mixture begins to boil, I let it simmer for about 3 minutes while stirring occasionally.
I remove the saucepan from the heat and stir in the freshly squeezed lemon juice.
I strain the mixture if needed for an extra smooth texture.
I pour the lemon posset into serving glasses or ramekins.
I refrigerate the dessert for at least 4 hours, or until fully set and chilled.
Before serving, I sometimes add a little lemon zest on top for extra freshness.

Variations

I sometimes add vanilla extract for a softer flavor alongside the lemon. When I want a slightly different citrus note, I use a mix of lemon and lime juice. I also enjoy topping the posset with fresh berries or crushed cookies for extra texture. For a more elegant presentation, I occasionally serve it in hollowed-out lemon halves. If I want a richer citrus flavor, I stir in a little lemon zest before chilling.

storage/reheating

I store the lemon posset covered in the refrigerator for up to 3 days. Since this dessert is meant to be served cold, I do not reheat it. I prefer keeping it chilled until right before serving so the texture stays smooth and creamy.
