Pumpkin Posset Recipe
If you love pumpkin pie but want to try something a little different this fall, this pumpkin posset is a fun one to make. It’s a chilled, creamy dessert with plenty of pumpkin pie spice and a little maple for sweetness. The texture is silky and spoonable, somewhere between a pudding and a custard, with a thin caramelized sugar topping that gives it a little crème brûlée feel.
I like serving these in hollowed-out mini pumpkins for a festive presentation, but you can just as easily make them in small jars or ramekins. The best part is how little equipment you need. No eggs to temper, no water bath, no oven, and no stand mixer. Just a saucepan, a whisk, and some time in the refrigerator.
If you’ve never made posset before, it’s a traditional English dessert made with just three basic ingredients: heavy cream, sugar, and an acid. As the mixture cools, the acid helps the cream set into a thick, silky dessert without the need for eggs or gelatin (think slightly thicker consistency of yogurt but still light and creamy). It’s a little like pot de crème, but much simpler to prepare. I have a few other versions on the blog, including my lemon posset, lime posset, and orange posset. This version takes that same simple technique and gives it a fall-inspired twist with pumpkin, warm spices, and maple.
Why This Recipe Works
- Citric acid creates the perfect set: It thickens the heavy cream just like lemon juice does in my lemon posset, but without adding any noticeable citrus flavor.
- Cooked-down pumpkin adds concentrated flavor: Reducing the pumpkin puree separately removes excess moisture and adds a layer of rich pumpkin flavor without compromising the creamy texture.
- Mini pumpkins make festive serving bowls: Hollowing out the pumpkins ahead of time helps them hold their shape and makes for a fun seasonal presentation.
- It’s easy to make ahead: The posset comes together in one saucepan and needs time to chill and set in the refrigerator, so it’s a great dessert to prepare the day before serving.
The Science of Posset
So how does cream thicken with no eggs? It comes down to the proteins in heavy cream. Normally they float around separately, so the cream stays liquid. When you add an acid like citric acid, the proteins stop repelling each other and link into a loose web. That web traps the fat and water, and that’s what makes posset thick and silky.
The other steps help that web form. Simmering for 3 minutes cooks off a little water, so the proteins and fat are more concentrated. The 5-minute rest keeps the cream from being too hot, which can make the proteins clump and turn grainy. Chilling firms up the fat and tightens the web.
Two more things matter here. Use heavy cream, because lighter dairy has less fat and won’t set the same way. And keep the pumpkin puree in its own layer. Puree is mostly water and fiber, so stirring it into the cream would weaken the set. I often get asked about substitutions, but truly a 3 ingredient based recipe relying on food science must stay as is for it to work!

- Maple Syrup
- Pumpkin Pie Spice
- Salt
For the Posset
- Heavy Cream
- Granulated Sugar
- Pure Maple Syrup
- Pumpkin Pie Spice
- Vanilla Extract
- Salt
- Citric Acid
- Water
Instructions
Prep the Mini Pumpkins (or jars)
Smaller pumpkins are dense and hard like other squash. I recommend softening them slightly by microwaving each pumpkin individually in 30-second increments. After the first 60 total seconds, I recommend puncturing the edge where you plan on slicing into to remove the top to allow a place for steam to escape. Most of my pumpkins were easiest to carve after 3 to 4 30-second intervals in the microwave.
After softening the pumpkin rind, cut the tops off and scoop out the seeds and strings. Brush the inside of the pumpkin with maple syrup and roast the pumpkins at 350°F for 10 minutes, then let them cool all the way to room temperature. Set them upright in a muffin tin if needed or place them on a baking sheet (you want them to sit flat and stable). If you fill them while they’re warm, the layers can melt together.
Preparing the Pumpkin Posset
Start with the puree. Cook the pumpkin puree, 1 Tbsp. maple syrup, 1/4 tsp. pumpkin pie spice, and a pinch of salt in a small saucepan over medium heat for 2 to 3 minutes. Keep stirring so it doesn’t burn.
Next, slowly stir in the heavy cream, sugar, 2 Tbsp. maple syrup, and the remaining 1 1/2 tsp. pumpkin pie spice. Bring the whole mixture to a gentle simmer, with small bubbles and no hard boiling, stirring until the sugar dissolves. Lower the heat and let it bubble gently for 5 minutes, stirring often.
Take the pan off the heat and stir in the vanilla. Let it cool for 5 minutes. Then dissolve the citric acid in the water and slowly whisk it into the posset for 30 seconds. To check that it has started to thicken, dip a spoon in. The posset should coat the back of the spoon and hold a line when you draw your finger through it.
Filling and Chilling
I find it easier to pour the posset into the pumpkins with a large liquid measuring cup or any heat-safe dish with a spout. You can also ladle it in. Carefully pour the warm posset into each pumpkin or ramekin. Let it set at room temperature for 45 to 60 minutes before chilling. Then chill for at least 4 hours, or overnight. I often leave mine uncovered in the fridge so a lid or wrap doesn’t damage the top of the posset as it sets.
Brûlée Topping (optional)
Do this right before serving. Sprinkle a thin layer of sugar over the top of each posset. Use a kitchen torch to melt the sugar until it’s deep golden brown. Let it sit for 1 minute so the caramel hardens, then serve right away.
Tips and Variations
- Don’t skip the 3 minute simmer or the 5 minute cool down. They matter more now that this recipe uses less acid.
- Fill each pumpkin to about 1/2 inch below the rim. If you have extra, chill it in a small ramekin.
- You can make these a day ahead. Keep them covered in the fridge and add the toppings right before serving.
- Want more spice? Bump the pumpkin pie spice in the posset up to 2 tsp.
- Want a firmer set with a little more tang? Use 1 tsp. citric acid instead of 3/4 tsp.
What to Use Instead of Citric Acid
- Lemon juice is the classic posset acid and the easiest swap. Use about 4 to 5 Tbsp. in place of the citric acid and water. It will add a lemon taste. If you want that, try my lemon posset.
- Lime or orange juice works the same way. See my lime posset and orange posset for how they turn out.
- Apple cider vinegar can work with fall flavors, but it is a weaker acid, so you need more of it and it can taste tangy. Try a small test batch first.
Juice adds extra liquid, so the set may be a little softer. Chill it overnight for the best result.
What to Pair With
- Crushed gingersnap cookies or biscoff cookies would be a fun topping
- A small dollop of whipped cream and a dusting of cinnamon or grated nutmeg
- Candied pecans
- A hot cup of chai, spiced coffee, or warm apple cider
Frequently Asked Questions
Pot de crème is a French custard made with egg yolks, cream, and sugar. It bakes in a water bath inside a baking dish. Posset has no eggs and no baking for the custard. The acid sets the cream while it chills in the fridge.
No. You’re not whipping or beating anything. A saucepan and a whisk are all you need.
Yes. Lemon juice has citric acid in it, so it sets the cream the same way. Use about 4 to 5 Tbsp. in place of the citric acid and water. It will add a lemon flavor, which is why I use citric acid in this pumpkin version.
Usually it’s one of two things. The cream didn’t simmer long enough, or there wasn’t enough acid. Let the cream bubble gently for the full 3 minutes and measure carefully.
Yes. Roast and blend the pumpkin until smooth, then cook it down in the saucepan until thick. Fresh puree holds more water, so it may need a few extra minutes on the stove.

- Cool completely to room temperature. Set upright in a muffin tin or on a baking sheet so they sit flat and stable.
Preparing the Pumpkin Posset
- Cook the pumpkin puree: 1 Tbsp. maple syrup, 1/4 tsp. pumpkin pie spice, and a pinch of salt in a small saucepan over medium heat for 2 to 3 minutes. Make sure to keep stirring so it doesn't burn.
- Next, slowly stir in the 2 cups of heavy cream, 1/2 cup of sugar, 2 Tbsp. maple syrup, and the additional 1.5 tsp. of pumpkin pie spice in a saucepan over medium heat.
- Bring the entire mixture to a gentle simmer (small bubbles- not boiling), stirring until the sugar dissolves. Lower the heat and bubble gently for 5 minutes, stirring often.
- Remove from the heat and stir in the vanilla. Cool for 5 minutes.
- Combine the citric acid with the water and stir to dissolve. Whisk in the citric acid slowly into the posset mixture for 30 seconds. The posset should coat the back of a spoon and hold a line if you draw your finger through it (a great way to test that it has begun to thicken).
- Carefully pour the warm posset mixture into each small pumpkin or ramekin. Allow the posset to set at room temperature for 45-60 minutes before chilling. I recommend chilling for a minimum of 4 hours or overnight (I often leave mine uncovered in the fridge so it doesn't damage the top of the posset as it sets).
