This vanilla posset recipe reminds me of a cross between creme brûlée custard (without the tricky sugar crust) and ice cream (but it’s not frozen). No ice cream freezer, oven, or torch is needed.

When you need a dessert to go with a heavy meal, this is it. Love your family and friends with this light but satisfying dessert.

This decadent treat was a big hit at our family dinner last weekend. Even the little ones ate it up.

Ingredients and substitutions:

Can you believe this recipe has only four ingredients? Use the best quality and freshest ingredients you can find!

  • HEAVY CREAM: No substitutes here. Nothing else will thicken like heavy cream.
  • SUGAR: Use granulated sugar. Again, I know of no substitutes.
  • LEMONS: Fresh lemons are vital. Bottled juice won’t cut it.
  • VANILLA: You have a couple of choices here. Vanilla extract is the cheapest and readily available. However, if. you can put your hands on a vanilla bean or vanilla bean paste, the reward is a luxurious dessert that tastes and looks extremely enticing.

    Using speck-heavy vanilla paste is so much easier than scraping a softened and split vanilla bean. In my area, I can buy it at Central Market, Williams-Sonoma, and of course, online. Try it in ice cream, pudding, custards, yogurt…actually, any dessert where you want to see the little black specks.

How to make a posset recipe with lemon:

  1. Bring heavy cream and sugar to a boil to transform the sweetened cream mixture into a velvety, thickened sauce.
  2. Add lemon juice to set and flavor the posset.
  3. Strain the sauce while pouring it into individual serving dishes to keep it silky smooth on the tongue. The posset will set and firm up as it chills.
  4. Garnish with raspberries, blueberries, or whatever fruit you can find that tastes and looks good. Raspberries are my personal favorite as they play well with lemon.

The optional powdered sugar adds a fancy touch with no special decorating skills. Place a tablespoon or two of powdered sugar into a small grocery-store-type strainer and gently tap the edge to make an even shower of “snow.”

FAQ about Vanilla Posset with Lemon:

What is a posset made of?

A posset consists of heavy cream, sugar, an acid like lemon juice, and sometimes additional flavorings. No eggs, gelatin, or baking is required.

What sets a posset?

The acid in the lemon juice sets the heavy cream.

Can I make posset ahead of time?

Yes. Your posset will need time to chill after you make it. Allow at least 3-4 hours before you want to serve it.

Can I substitute half-and-half for heavy cream?

No, the fat content in heavy cream helps make this posset thick. It won’t be the same if you use something else.

Can I substitute vanilla extract for the vanilla bean?


Parting thoughts: This posset is a great dessert after a heavy meal or for a ladies luncheon. Other good desserts include this Blackberry Ice Cream, Creme Fraiche Ice Cream, and my favorite, Coffee Ice Cream.
