Lemon Posset Recipe
This Lemon Posset in Lemon Cups is a decadent, creamy citrus dessert made with three simple ingredients. It is served in hollowed-out lemon halves for an elegant presentation. With its silky texture, bright lemon flavor, and no-bake simplicity, this easy lemon posset recipe is the perfect make-ahead dessert.
Lemon Posset is one of the easiest desserts you’ll ever make, yet it delivers an elegant and creamy texture with bright citrus flavor. This classic British dessert dates back to the Middle Ages, originally served as a hot drink for medicinal purposes before evolving into the rich, pudding-like texture we know today.
With just three simple ingredients, no baking, and minimal effort, this lemon posset recipe is a perfect choice for dinner parties, baby showers, or when you just need a refreshing dessert. Best of all, we’re taking it up a notch by serving it in lemon cups for a beautiful presentation that makes the result extra special!
Why This Recipe Works
- Minimal Effort, Maximum Elegance: With just a heavy cream, sugar mixture, and fresh lemon juice, you get a creamy dessert with a silky smooth finish.
- Naturally Thickens Without Egg Yolks: The citric acid in the citrus juice reacts with the cups of cream, thickening the cream mixture to create a stable, luscious texture.
- Perfect for Make-Ahead Desserts: Since it needs a few hours to set at room temperature, this is a great option for dinner parties and gatherings where you want a stress-free dessert.
Supplies Needed
To make these lemon posset cups, you’ll need:
- A pairing knife for making the lemon cups
- A small saucepan
- A measuring cup
- A muffin tin or small cups to keep the lemon halves stable while setting
Ingredients
- Lemons: Used for both fresh lemon juice and as lemon shells for serving. Meyer lemons work beautifully for a slightly sweeter touch.
- Heavy cream / Double cream: Provides a rich, velvety texture. I do not recommend using other types of milk or non-dairy milk. You need cream for this to work.
- Sugar mixture: Caster sugar or superfine sugar dissolves best. Do not substitute other sweeteners.
- Lemon zest: Adds an extra burst of lemon flavor to enhance the fresh lemons.
- Garnishes: Fresh berries, fresh mint, or a dusting of lemon peel zest add a finishing touch.
Substitutions & Variations
- Try a lime posset or orange posset by swapping out the citrus varieties.
- If you love more texture, swirl in a bit of lemon curd for extra citrus depth.
- Want a fun topping? Give it a brulee!
How To Make Lemon Cups
- Prepare the Lemons: Cut the whole lemons in half widthwise. Using a spoon or a food processor (if needed), carefully scoop out the flesh and juice without puncturing the lemon rinds.
- Strain the Juice: Using a fine sieve, strain the fresh lemon juice to remove any pulp or seeds. You’ll need about tablespoons of lemon juice for the posset.
- Stabilize the Lemon Cups: Place the lemon shells in a muffin tin or small cups so they sit upright while filling.
How to Make Lemon Posset
- Simmer the Cream Mixture: In a small saucepan over medium heat, combine the heavy cream, sugar mixture, and optional lemon zest. Stir occasionally and bring to a gentle simmer.
- Cook for 3 Minutes: Let it bubble lightly over medium-high heat, stirring frequently to prevent burning.
- Incorporate Citrus Juice: Remove from heat and slowly whisk in the citrus juice. The posset set process begins immediately as the hot curdled milk thickens into a smooth cream mixture.
- Fill the Lemon Cups: Carefully pour the warm mixture into the lemon halves.
- Let it Set: Allow them to cool to room temperature, then refrigerate for at least 3-4 hours until fully set.
Expert Tips
- Best Results: Use fresh lemon juice, not bottled, for the best lemon flavor.
- Avoid Overheating: Keep the heat at a medium temperature with a gentle simmer to prevent scorching.
- Storage Tip: Store leftovers in an airtight container and cover with plastic wrap to maintain freshness.

Lemon Posset Recipe
Ingredients
- 4 large Lemons for juice and cups (6 tbsp of juice)
- 2 cups Heavy Cream
- 1/2 cup Granulated Sugar
- 1 tbsp Lemon Zest
Optional Garnishes
- 1 tbsp Sanding Sugar or decorative sugar
- 8 Berries Raspberries or Blueberries
Instructions
Prepare the Lemon Cups
- Cut the lemons in half widthwise. Using a spoon or small knife, carefully scoop out the flesh and juice, being careful not to puncture the rind.
- Save the inside flesh of the lemon, squeeze out the juices and strain into a bowl or cup and set it aside for the filling. You will need 6 tbsp of reserved lemon juice for the filling.
- Set the halved lemon cups onto a tray or plate so they are sitting upright and are stable.
Make the Lemon Posset
- In a medium saucepan over medium heat, combine the heavy cream, sugar, and lemon zest (if using). Stir and bring to a gentle simmer. Do NOT let the cream boil- if it gets too hot it could curdle when you add in the lemon juice.
- Let it bubble lightly for 3 minutes, stirring frequently.
- Remove the pan from heat and slowly whisk in 6 tbsp of the reserved lemon juice. The mixture will begin to thicken naturally as you do this. It will thicken even more as it continues to cool.
Fill and Chill
- Carefully pour the warm posset into the prepared lemon cups (or into small jars if not using the cups). It helps to add the lemon posset filling into a liquid measuring cup with a pour spout for easier transfer.
- Let them cool at room temperature for about 30 minutes, then refrigerate for at least 2.5-3 hours or until fully set.
- Before serving, you can garnish with sanding sugar and a berry if desired.

What are the sprigs that you used to garnish with?
Just poured into the lemon cups and it tastes great so far. Incredibly easy to make while watching two little ones.
So easy to make and it tastes fabulous 👌 I added a little vanilla while I was cooking it and when it was ready to serve I added some sugar to the top and torched it so it was almost like lemon cream brule…delicious!
Sounds wonderful!
Can I make this 2 days ahead? And just keep it in the fridge?
Yes! When I made batches they have lasted 4-5 days and were still good!
Are there any changes when you try it with orange? My first 4 batches of lemon were an absolute HIT. I wanted to try orange and my consistency changed. Almost, grainy. Thinking I didn’t cook the sugar down enough but I timed it like I did the others. Trying again this weekend, thank you for any feedback as well as this amazing recipe!!
Hi Makayla,
So oranges will technically work but there’s a few things to note. Orange juice is naturally less acidic than the lemon juice is. You need a higher level of acidity to essentially curdle the cream to get it to thicken. The easiest way to do this is to shoot for 4 tbsp of the orange juice and maybe 2 tbsp of lemon to up the acidity level. You could also reduce the orange juice down in a pan and let it cool prior to using. This will intensify the flavor and could help balance the acidity levels as well. Also, it may just need a few extra hours of chilling time. Hope those are some possible solutions for you and I am so glad you are enjoying the recipe!
What a wonderful dessert!!! I am lactose intolerant and substituted LF cream and also used Cane sugar. It was creamy and smooth and my entire family loved it!
I inadvertently added all the lemon juice I squeezed out of the four lemons rather than measuring 6 tbls and it still setup and was delicious. 😉
Oh wow haha- that had to be strong! Glad it still set up though!
I’ve made this twice with lemons & it was incredible! I added coloured decorative sugar and edible flowers to garnish. I tried making it with oranges but it didn’t set? It was still delicious, I added vanilla and they tasted like a creamsicle! Maybe because they’re bigger than lemons I needed more cream? Will try again but it was a big hit!
