Prune Plums are tasty blue and purple plums with a green flesh. These flavourful plums are in season right now in the Okanagan and there are so many ways to use them. In this post, I am sharing a Caramelized Prune Plum Frangipane Galette recipe that has a unique caramelized plum filling that you will enjoy trying. Roasting the plums transforms the flesh into a pretty rose colour and a distinct fragrant flavour. I have developed this recipe to include almonds, caramel and vanilla bean extract, all of which pair extremely well with plums.
Plums are also noted for their health benefits: they are low calorie and contain over 15 vitamins and minerals, in addition to dietary fibre and antioxidants, which are helpful in reducing inflammation and controlling blood sugar. Examples of sweet dishes plums can be used in are a plum paste (delicious with cheese) or as a filling in pastry; in a confiture, tart or cake or plum kuchen, to name a few. Examples of savoury dishes are perogies with plum filling, pork tenderloin with plum sauce, and plum chutney.

Galettes are a great way to start experimenting with pastry because they do not require the precise care that is taken with a tart or pie shell. They are free-form pies, rustic in nature and delicious. Give it a try!

CHEF TALK: This galette recipe utilizes plums in a unique way. They are roasted in the oven using a French technique which uses sugar and butter to help caramelize the fruit. I use brown sugar to roast the plums because it lends well to creating the caramel flavour that pairs well with the plums. For step-by-step instructions on how to make the pâte brisée pastry, please refer to my link below. I will be posting a gluten-free (and dairy-free adaptable) pâte brisée pastry recipe very soon (the crust shown in the photographs in this post is created from gluten-free pâte brisée).
INGREDIENTS:
- 1 recipe Pâte Brisée
_______________ - 2 lbs. (908 g) prune plums, halved and pitted
- 2/3 cup (113 g) brown sugar
- 1 tablespoon (15 ml) vanilla bean paste or vanilla extract
- 1/2 teaspoon (2.5 ml) almond extract
- 2 tablespoons (30 g) cold butter, cut into small pieces
______________
- 2/3 cup (180 g) Frangipane Filling (recipe follows)
________________
For the top of the galette:
- Egg wash (1 egg mixed with 1 teaspoon water)
- 1/4 cup (25 g) sliced almonds
- 2 tablespoons (30 g) organic cane sugar or granulated sugar for sprinkling
Almond Frangipane Filling:
INGREDIENTS:
- 5 Tablespoons (75 g) unsalted butter, at room temperature
- 1/3 cup (70 g) granulated sugar or organic cane sugar
- 1 large egg
- Pinch of salt
- 2 teaspoons (10 ml) vanilla extract or vanilla bean paste
- ½ teaspoon (2.5 ml) almond extract
- ¾ cup (90 g) ground almonds
METHOD:
- Preheat the oven to 375°F or 350°F for a convection setting.
- Line a baking sheet with a sheet of parchment paper large enough to extend over the sides slightly (this is to contain any excess plum juices).
- Prepare the pâte brisée according to recipe directions and chill for one hour.
- Toss the halved plums with brown sugar, vanilla bean paste and almond extract. Place the plums cut side down on the sheet of parchment. Dot the plums with the small pieces of cold butter. Roast the plums for 40 minutes for one hour until the plums are caramelized and the remaining juices (caramel) are thick and sticky. Set the baking sheet aside to cool while you roll out the pastry. Raise the temperature of the oven to 425°F or 400°F if using a convection setting.
- Roll out the pastry on a lightly floured piece of parchment paper to approximately 15″ diameter. Chill in the refrigerator while you are preparing the filling.
- Make the Almond Frangipane Filling: In a mixing bowl, cream the butter, sugar, and salt together by hand. Beat in the egg, and vanilla and almond extract. Stir in the ground almonds. Set aside. Spread the centre of the pastry with the 2/3 cup of frangipane filling as shown in the photograph.
- Lay the caramelized plum halves on top of the frangipane filling in a pretty pattern. Drizzle the plums with any sticky juices that remain on the baking tray.
- Fold the edges of the pastry over the filling as shown in the photograph. It does not have to be perfect – a galette is rustic, yet elegant in its simplicity.
- Brush the pastry with egg wash, then sprinkle the pastry with the sliced almonds. Finally, sprinkle the sugar on top of the pastry.
- Bake in a preheated oven for 10 minutes, then lower the oven to 375°F or 350°F for convection setting and then bake for a further 30 minutes or until the pastry is golden and the fruit is bubbling. Leave to cool on a rack.
- Serve the galette warm or at room temperature with Creme Anglaise or a scoop of vanilla bean ice cream.

Denise, you are the Queen of pastries. Your Prune Plum Frangipane Galette looks amazing and the plating image is worthy of front page placement in any food publication. Alas, our prunes didn’t make this year. But, this has been printed out and place in my to be made binder. A five-star recipe.
That is so sad that you did not get prune plums this year, however, this recipe works well with apricots too! The galette is not too sweet despite the caramelization of the fruit, yet it is very flavourful. I am looking forward to hearing if you make it in the future. I always love your kind comments – they make my day! 🙂
Guess what I have in my fridge right now? A whole BOX of plums! Yum…they only last so long, just like summer.
Yay! Plums are a treasure! What will you make with yours? Have fun experimenting with your box of plums. I wish you could taste this galette, Bernice. It is so good! 🙂
Lovely recipe! I appreciate the step-by-step photos. I am allergic to stone fruit, so would I be apple to make the galette with berries?
Thank you so much, Liliana. I appreciate your comments very much. You could definitely make this galette with apples or berries, for sure. As a matter of fact, caramelized apple galette is my favourite!
My very favourite plums! And I love that you roasted them. Is there anything more yummy than caramelized fruit? Great recipe, Denise! Thanks for sharing.
thank you so much for stopping by, Elaine! I love plums too. Caramelized fruit is the best, isn’t it?
Oh.My. Gosh. This looks so pretty and sounds amazing! Plums are one of my favorite fruits. Definitely Pinning this for later!
Thank you very much, Jo! So many people tell me that plums are one of their favourite fruits – I like to hear that! Thanks for pinning my recipe – if you try it, please leave me a comment. I would love to hear about it. 🙂 Cheers!
This looks so delicious and unique! Galette’s are the best and filling them with plums is even better!
Thank you so much, Terri!
Prune plums are one of my favorites…
I have so many wonderful memories associated with this wonderful fruit. This galette looks amazing and I can already taste how delicious it is. I love that you roasted the fruit… I am a huge fan of roasting fruits and veggies. Have pinned to try. Thanks for another wonderful recipe Denise ♥
Thank you so very much, Maria! Your kind words mean the world to me. I am also a huge fan of roasting both fruits and vegetables – the flavours are outstanding, aren’t they? Thanks so much for stopping by Urb’n’Spice. Let me know if you try this galette – I know you will enjoy it! 🙂
This was by far the most exquisite fruit dessert- from the pate brisee to the frangipane to the caramelized plums. And it presented beautifully! I prepared all three steps ahead of time, assembled and popped it into the oven just before dinner. I can’t wait to try a caramelized apple version!
Thank you so much for your kind comments, Christine. You are my ‘comment of the day’ on Instagram @urbnspice. This is a lovely dessert and so much less trouble than a pie. It uses plums in the best way, doesn’t it? I am thrilled that you loved this recipe as much as we do. Thank you very much for stopping by Urb’n’Spice. 🙂
