Flaky Baking Plum Tarts With Almond Crumble

Let me be real with you: the moment you pull these plum tarts out of the oven, golden and bubbling, your kitchen will smell like a French patisserie. And honestly? That alone is reason enough to make them. These flaky baking plum tarts with almond crumble are the kind of dessert that makes people think you trained in Paris.

I stumbled onto this recipe on a Sunday afternoon with a pile of overripe plums and zero patience for complicated desserts. What came out of the oven was nothing short of a revelation. Buttery crust, juicy spiced plums, nutty crumble on top — it just works.

“Flaky, jammy, crumbly, and dead simple. These plum tarts deliver serious wow-factor without demanding pastry-chef skills. Weekend baking, sorted.”

Why These Plum Tarts Are Worth Your Saturday

You might be wondering: why plums? Because plums do something magical in the oven — they soften, release their gorgeous ruby juices, and turn deep and jammy in a way that peaches and apples just don’t. Paired with cinnamon and brown sugar, they become a straight-up flavor bomb.

The almond crumble adds crunch and nuttiness that balances the fruit perfectly. FYI, this is also one of those bakes that looks impressively complicated but really isn’t. You get maximum applause for minimum effort, and that’s a deal I’ll take every time.

Ingredients You’ll Need

Here’s everything organized by component. No hunting through a dense paragraph.

The Crust

• 2 cups all-purpose flour
• 1/2 cup unsalted butter, chilled & cubed
• 1/4 cup granulated sugar
• 1/4 tsp salt
• 1/4 cup ice water

Plum Filling

• 4 ripe plums, pitted & sliced
• 2 tbsp brown sugar
• 1 tsp cinnamon

Almond Crumble

• 1 cup almond flour
• 1/4 cup rolled oats
• 1/4 cup slivered almonds
• 1/4 cup melted butter
• 1 tsp vanilla extract
• 1 pinch salt

How to Make Flaky Baking Plum Tarts With Almond Crumble

Let’s walk through every step in real detail. I’ll explain what to look for and why each move matters, so you bake with confidence — not crossed fingers.

Step 1: Build the Tart Crust

Grab a large mixing bowl and combine 2 cups of all-purpose flour, 1/4 cup granulated sugar, and 1/4 teaspoon of salt. Whisk them together quickly so everything distributes evenly. Now drop in your chilled, cubed butter.

Here’s the single most important technique in this whole recipe: use your fingertips — not your palms — to rub the butter into the flour mixture. Your palms run warm and will melt the fat before it does its job. Use a quick, snapping motion with your thumb and fingers, working the butter in until the mixture looks like rough, uneven breadcrumbs. Some pea-sized chunks are totally fine — those are your future flaky layers.

Now drizzle in ice water, one tablespoon at a time, mixing gently with a fork after each addition. Stop the moment the dough just barely holds together when you pinch it between two fingers. Over-mixing activates the gluten and gives you a tough crust — and nobody wants that. Shape the dough into a flat disc, wrap tightly in plastic wrap, and chill in the refrigerator for at least 30 minutes. Yes, the waiting is annoying :/

Step 2: Prepare the Plum Filling

While the dough chills, preheat your oven to 375°F (190°C). Pit your 4 ripe plums and slice them into thin wedges, roughly 1/4 inch thick. You want slices thin enough to soften nicely in the oven without turning to mush.

Toss the plum slices in a bowl with 2 tablespoons of brown sugar and 1 teaspoon of cinnamon. Stir gently until every slice gets a good coat. Let this sit for 5 to 10 minutes. You’ll notice the plums start releasing their gorgeous juices — that’s exactly what you want. That syrupy pooling is what makes the filling so intensely fruity once baked.

Step 3: Make the Almond Crumble

In a separate bowl, combine 1 cup almond flour, 1/4 cup rolled oats, and 1/4 cup slivered almonds. Pour in 1/4 cup of melted butter, add 1 teaspoon of vanilla extract, and throw in a pinch of salt. Mix everything together with a fork until it forms rough, irregular clumps.

Don’t overmix — you want chunky crumble, not a smooth paste. The slivered almonds are IMO completely non-negotiable here. They add a distinctive crunch and a toasted, nutty depth that makes the topping genuinely memorable. The vanilla does more work than you’d expect too; it rounds out the nuttiness beautifully.

Step 4: Roll and Line the Tart Pans

Pull the chilled dough from the fridge and let it rest on the counter for about 5 minutes. It should be firm but pliable — not cracking when you press it. On a lightly floured surface, roll it out to about 1/4 inch thickness. Try to roll evenly from the center outward, rotating the dough a quarter turn each time so you get a uniform thickness throughout.

Cut circles to fit your tart pans — roughly 4 to 5 inches for individual tarts. Gently lift each circle and ease it into the pan without stretching. Stretching causes shrinkage during baking. Just press it lightly into the base and up the sides. Trim any excess dough with a sharp knife. This recipe makes 6 to 8 individual tarts depending on your pan size.

Step 5: Fill, Top, and Get Excited

Spoon the cinnamon-plum mixture evenly into each tart shell. Spread the slices out so you get fruit in every bite, and leave a small gap at the rim for the crumble. Now pile on the almond crumble generously — press it down very lightly so it sits into the fruit rather than floating on top.

Step 6: Bake to Golden Perfection

Place your loaded tarts on a rimmed baking sheet before sliding them into the oven. This step is non-negotiable — the plum juices will bubble over and you’ll have a smoky, sticky oven if you skip it. Bake at 375°F for 25 to 30 minutes.

What you’re looking for: a deep golden crust, a bubbling filling, and a crumble that’s toasty and set. After the 20-minute mark, peek at the crumble. If it’s browning faster than the crust, loosely tent a piece of foil over the top for the remaining time. Once done, let the tarts cool on a wire rack for at least 10 minutes before removing from the pans — the filling needs time to set.

Step 7: Serve and Collect Your Compliments

These tarts are honestly stunning served warm with a scoop of vanilla ice cream or a generous dollop of crème fraîche. The contrast of the warm tart and cold cream is genuinely one of life’s little pleasures. They’re equally great at room temperature, which makes them perfect for dinner parties where you need to prep ahead. Have you ever had a dessert this easy that looked this impressive? Exactly.

Tips for the Best Flaky Plum Tarts Every Time

• Keep everything cold. Cold butter creates the steam pockets that make pastry flaky. If your kitchen is warm, chill the bowl too.
• Use ripe but firm plums. Overripe fruit turns to mush; under-ripe plums stay too tart and don’t soften properly during baking.
• Always use a baking sheet under the tarts. The plum juices absolutely will bubble over. Your future self will be grateful.
• Make the dough the night before. Overnight chilling makes the dough even easier to roll and improves the texture of the crust.
• Experiment with the fruit. Nectarines, cherries, or apricots all pair beautifully with this exact almond crumble topping.

Storage and Make-Ahead Notes

Store these tarts at room temperature for up to 2 days, loosely covered. For longer storage, refrigerate for up to 4 days — warm them in a 300°F oven for 8 minutes before serving to bring back the crunch. The flavor actually deepens overnight, which is a happy bonus.

To freeze: wrap tarts individually in cling wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge and reheat in the oven at 325°F for 10 to 12 minutes. Good as new.

Frequently Asked Questions

Can I use frozen plums instead of fresh?

Yes. Thaw the plums completely and drain off any excess liquid before using them. Frozen plums tend to release more moisture during baking, so you may need to add an extra tablespoon of almond flour or flour to the filling to absorb the juices.

What are the best plums for these flaky baking plum tarts with almond crumble?

Firm, ripe plums work best. Black plums, red plums, and Italian prune plums all bake beautifully and develop a rich, jammy texture without becoming mushy.

Can I make the tart dough ahead of time?

Absolutely. The dough can be prepared up to 2 days in advance and stored in the refrigerator. You can also freeze it for up to 3 months. Thaw overnight in the refrigerator before rolling and baking.

How do I keep the crust flaky?

The key is keeping the butter cold throughout the process. Avoid overworking the dough, use ice water, and chill the dough before rolling. Cold butter creates steam pockets during baking, which produce those desirable flaky layers.

Can I use a different fruit instead of plums?

Yes. This recipe works well with peaches, nectarines, apricots, cherries, or a combination of stone fruits. The almond crumble pairs especially well with most summer fruits.

How should I store leftover plum tarts?

Store the baked tarts loosely covered at room temperature for up to 2 days or refrigerate them for up to 4 days. Reheat in a 300°F (150°C) oven for a few minutes to restore the crisp texture.

Can I freeze baked plum tarts?

Yes. Allow the tarts to cool completely, then wrap them individually in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator and warm in the oven before serving.

Why is my filling too watery?

This usually happens when very ripe plums release extra juice during baking. Letting the sliced plums sit with the sugar for a few minutes before assembling the tarts helps control excess moisture. Baking the tarts until the filling is actively bubbling also helps thicken the juices.
