Why This Recipe Stands Out
We love a good dessert that's both refreshing and satisfying, and this Lemon Posset with Coconut Shortbread Crust hits all the right notes. Here's why we're obsessed with this recipe:
- Perfect Balance: The tangy lemon posset perfectly balances the sweet, buttery crust. It's a lot like my Pumpkin Caramel Pie.
- Easy to Make: All of the steps in this recipe are simple and straightforward, making this an easy dessert to prepare.
- Can be Prepared Ahead: This dessert needs to set in the fridge for 2 hours, making it the perfect make-ahead dessert for parties or gatherings.
- Looks Impressive: This dessert looks stunning when served in individual ramekins! It’s a great choice for dinner parties, just like my Lavender Panna Cotta.
- Versatile: The combination of lemon and coconut is a classic, but you can customize this recipe by trying different fruit and crust combinations.
Key Ingredients
- Shortbread Cookies - These form the base of our crust, adding a rich, buttery flavor and a crumbly texture.
- Lemons - We use both the zest and juice of these to add a tangy, citrusy flavor that cuts through the richness of the cream.
- Heavy Cream - This is the main ingredient for our posset, and when combined with the lemon, it creates a lusciously smooth and creamy dessert.
Substitutions and Variations
Here are some of our favorite variations and substitution ideas:
- Crust: While we love the buttery flavor of shortbread cookies, you can definitely get creative with the crust. Try using graham crackers, chocolate sandwich cookies, or even a gluten-free cookie option.
- Macadamia Nuts: If you're not a fan of macadamia nuts, you can substitute them with almonds or omit them altogether.
- Sweeteners: Feel free to experiment with the sweeteners. Honey or agave nectar could be a good substitute for cane sugar.

Recipe
Lemon Posset With Coconut Shortbread Crust
Ingredients
- ¼ c macadamia nuts
- 3 shortbread cookies 1.5 oz, or any other cookies of your choice
- 1 tablespoon butter melted
- 3 lemons zested and juiced
- ¼ c cane sugar
- 1 teaspoon vanilla extract
- 1 ½ c heavy cream
Instructions
- Place macadamia nuts and cookies on a sheet of parchment paper and fold it like an envelope. You can also use a zip-top bag.
- Using a rolling pin, roll across the parchment, applying slight pressure until the nuts and cookies are crushed into smaller pieces. Transfer them to a small bowl. Pour in the melted butter and mix to combine.
- Divide the nut and cookie mixture between 4 small dessert pots and, using the back of a wooden spoon, press down to pack it firmly. Place the dishes in the fridge to firm up.
- In a medium pot, combine lemon zest, lemon juice, sugar, and vanilla. Cook over medium-low heat, stirring occasionally, until the sugar dissolves and the syrup becomes aromatic, about 15 minutes.
- Remove the syrup from the heat, add the heavy cream, return the pot to the heat, and continue simmering for 10 minutes.
- Remove the dessert pots from the fridge.
- Strain the cream mixture through a fine-mesh strainer and let it cool for a few minutes before dividing it between the dessert pots.
- Cover the dessert pots with plastic wrap and return them to the fridge to set for 2 hours.
- Serve garnished with fresh berries or lemon zest.
Notes
- Use a zip-top bag to crush the macadamia nuts and cookies if you don't have parchment paper. It's a neat and efficient way to get them to the right consistency.
- Press the nut and cookie mixture firmly into the dessert pots. This will help the crust hold together and give it a satisfying texture.
- Allow the syrup to cool for a few minutes after adding the heavy cream. This will prevent the cream from curdling and give your posset a smooth, velvety texture.
- Serve your Lemon Posset garnished with fresh berries or additional lemon zest for a pop of color and a refreshing contrast to the sweet, creamy posset.
