This almond flour plum cake delivers layers of tender crumb and juicy plums in every bite—no dry crumb here. The secret lies in almond flour's natural moisture retention and how we prepare the plums for maximum flavor infusion. I developed this recipe after years of perfecting almond flour cakes, and the plum maceration technique ensures they stay perfectly tender while adding natural sweetness.
Almond flour requires precise technique—no overmixing or it becomes dense—but the result is a cake that's naturally gluten-free, richly textured, and packed with fruit-forward flavor. We'll use a combination of eggs and applesauce for moisture, while a touch of lemon zest brightens the plums' natural sweetness. The baking process is gentle to prevent over-browning, preserving that golden, inviting crust.
What you'll end up with is a cake that's moist through and through, with plums that burst with juice in every forkful. The crumb stays tender for days, making it perfect for tea time or dessert gatherings. The almond flour adds a delicate nuttiness that complements the plums beautifully, creating a dessert that feels both elegant and comforting.
Serve warm with a dusting of powdered sugar or a dollop of whipped cream, and pair it with a cup of Earl Grey for the ultimate afternoon treat. The recipe includes optional flax eggs for a vegan version, so everyone at the table can enjoy it. Let's get baking!
Ingredients for almond flour plum cake
Eight simple ingredients transform into a cake that's moist, fruity, and naturally gluten-free.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 ½ cups | Superfine for best texture |
| Fresh Plums 🍑 | 2 ½ cups | Pitted, halved, plus extra for maceration |
| Large Eggs 🥚 | 4 whole | Room temperature preferred |
| Unsweetened Applesauce 🍎 | ½ cup | Unsweetened for natural flavor |
| Granulated Sugar 🍚 | ¾ cup | Light brown sugar for depth |
| Vanilla Extract 🌿 | 1 tsp | Pure extract, not imitation |
| Lemon Zest 🍋 | 1 tbsp | From 1 organic lemon |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Baking Powder 🧂 | 1 ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Powdered Sugar 🍚 | ¼ cup | For dusting, optional |
| Ground Flaxseed 🌾 | 2 tbsp | For vegan flax eggs (optional) |
| Water 💧 | 6 tbsp | For flax eggs (optional) |
The almond flour is the star—Bob's Red Mill or Anthony's Goods are my go-tos for consistent quality. Look for the super-fine grind; anything coarser can make the cake dense. Plums are key too: firm, ripe ones work best—think Rainier or Italian prunes if fresh aren't available. I always buy extra and freeze the rest. The lemon zest and juice? Organic lemons from the store's produce section give the brightest flavor. If you're making the vegan version, grab the flaxseed from the bulk bin—it's cheaper and fresher.
No almond flour? Substitute with 2 cups gluten-free 1:1 baking flour, but the texture won't be quite the same. Plums too tart? Toss them with 1 tbsp sugar during maceration. Short on eggs? The flax eggs work perfectly—just mix the ground flaxseed with water and let it sit for 5 minutes. No vanilla extract? Vanilla bean paste adds little flecks of flavor magic. The baking powder is non-negotiable here—aluminum-free keeps the cake tender. For the sugar, light brown adds depth, but white works in a pinch.
Store the cake in an airtight container at room temperature for 2 days—it actually gets better as it sits. For longer storage, wrap tightly and refrigerate for up to 1 week. The plums stay juicy, so don't skip the maceration step. I always make a double batch—one for now, one to freeze for 3 months. Just thaw at room temperature before serving. The powdered sugar? Only if you're feeling fancy—it's totally optional but makes it feel extra special.

Step-by-step instructions for almond flour plum cake
Here's how to bake a tender, fruit-filled cake that stays moist for days.
Prepare the Plum Filling
Start by tossing the extra plums you set aside for maceration with the 2 tablespoons lemon juice and 1 tablespoon lemon zest. Let them sit for 10 minutes—this brightens their flavor and softens them slightly. Then, chop the 2.5 cups fresh plums you'll use in the cake into ½-inch chunks and set them aside in a bowl.
In a small saucepan, combine the 0.5 cup unsweetened applesauce and 0.75 cup granulated sugar. Simmer over medium heat for 5 minutes, stirring occasionally, until the sugar dissolves and the mixture thickens slightly. Remove from heat and stir in the macerated plums. This creates a jammy filling that keeps the cake wonderfully moist.
Mix the Batter
Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. In a large bowl, whisk together the 2.5 cups almond flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. This dry mix ensures even distribution of leavening agents for a light texture.
In another bowl, beat the 4 whole large eggs until frothy, then whisk in the 1 teaspoon vanilla extract. Gradually add the dry ingredients to the wet, mixing just until combined—overmixing develops gluten and makes the cake dense. Fold in the plum-applesauce mixture until evenly distributed. The batter will be thick but pourable.
Bake the Cake
Pour the batter into your prepared pan and spread it evenly. Bake for 35-40 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. I like to tent the pan with foil after 20 minutes to prevent overbrowning if your oven runs hot.
Here's the thing—almond flour cakes can dry out quickly, so don't open the oven door early. The cake should spring back slightly when pressed gently in the center. If the edges brown too fast, rotate the pan halfway through baking for even coloring.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This resting period allows the cake to set properly and prevents it from crumbling when you slice it.
Once fully cooled, dust the top with 0.25 cup powdered sugar for a delicate finish. For extra richness, you can brush the warm cake with a simple syrup made by heating 2 tablespoons water with 2 tablespoons sugar until dissolved. Serve slices at room temperature for the best texture—this cake stays moist for days when stored in an airtight container.
Pro Tips For Making Almond Flour Plum Cake
- Bake at 325°F—Not Higher: Almond flour burns faster than regular flour, and plum cakes need gentle heat to stay moist. I learned this the hard way—cranky at 350°F, the top browned while the center stayed doughy. Preheat your oven, then stick a thermometer in there to confirm. (Yes, even if your oven says it’s ready.)
- Pit and Slice Plums Like a Pro: Ditch the food mill—it turns plums to mush. Instead, halve the plums, scoop out pits with a small spoon, then slice them into ¼-inch pieces. Toss them in a bowl with 1 tablespoon of sugar and let them sit for 10 minutes. This draws out juices, so they caramelize better in the cake and don’t make it soggy later.
- Don’t Overmix the Batter: Almond flour is finicky—once you add the eggs and applesauce, mix just until combined. I used to beat it like I was trying to win a baking contest, and the cake turned dense and rubbery. Think "fold in" rather than "stir vigorously." A spatula and 10 gentle swirls are all you need.
- Use Room-Temp Eggs and Applesauce: Cold eggs and thick applesauce make the batter lumpy and uneven. Take the eggs out 20 minutes before mixing, and if your applesauce is straight from the fridge, microwave it for 15 seconds to loosen it up. Trust me, your cake’s texture will be smoother—and less likely to sink in the middle.
Make-ahead tips for this dish
Prep Ahead Strategy
Almond flour cakes benefit from overnight prep—mix the batter up to 24 hours ahead and store it in an airtight container in the fridge. The flavors meld beautifully, and the almond flour absorbs moisture gradually for a richer texture. I always prep the plum maceration first, then mix the batter the night before. This saves 30 minutes of active time on baking day. 🌰
Fruit Prep Shortcut
Skip the last-minute plum chopping by prepping all fruit components 3 days ahead. Pit and halve the plums, then store them in a sealed container with a sprinkle of lemon juice to prevent browning. The maceration can also be done in advance—just keep it refrigerated until you're ready to fold it into the batter. This turns a 10-minute task into a 2-minute assembly on baking day. 🍑
Batter Storage Tips
For longer storage, divide the batter into two 1-cup portions and freeze them in silicone molds or small airtight containers. Thaw overnight in the fridge before baking—just add 5-10 minutes to your bake time since cold batter takes slightly longer to set. I've successfully stored batter for up to 2 weeks this way without texture issues. 🧊
Plum Compote Make-Ahead
Make the plum-applesauce compote 2 days ahead and store it in a clean jar in the fridge. The flavors deepen over time, creating a more concentrated jam-like texture. When ready to bake, simply fold it into your freshly mixed batter. This works especially well if you're making a double batch—just double the compote recipe and freeze half for next time. ✨
Freezer-Friendly Slices
Cut the fully baked and cooled cake into slices and wrap each piece tightly in plastic wrap, then place them in a freezer bag. These freeze beautifully for up to 3 months and reheat perfectly in the microwave for 20-30 seconds with a damp paper towel. The almond flour keeps them moist even after freezing—just avoid thawing at room temperature to prevent sogginess. 🍰
Weekday Prep Hack
For busy mornings, bake the cake completely the night before and store it at room temperature. In the morning, simply reheat slices in a 350°F oven for 5-7 minutes to revive the texture. This works especially well for office lunches—just pack slices with a small container of whipped cream or jam for a complete treat. The cake's natural sweetness pairs perfectly with coffee too! ☕

Frequently asked questions
Can I substitute other fruits besides plums?
This cake works beautifully with peaches, apricots, or even berries like blueberries or raspberries. For stone fruits, macerate them with lemon juice and 1 tbsp sugar for 10 minutes before baking. Berries should be tossed with 1 tbsp cornstarch to prevent sinking. The key is keeping the fruit juicy but not soggy.
Why does my almond flour cake turn out dry?
Almond flour absorbs moisture quickly, so overbaking or overmixing are common culprits. Bake until a toothpick comes out clean but not dry—35-40 minutes at 350°F is ideal. Avoid overmixing the batter (just until combined) and consider adding 1 extra tbsp applesauce if your kitchen is dry. Store leftovers in an airtight container with a slice of bread to retain moisture.
How do I make this cake vegan?
Replace the 4 eggs with 4 flax eggs (made by mixing 4 tbsp ground flaxseed with 10 tbsp water, let sit for 5 minutes). Use vegan vanilla extract and ensure your butter is plant-based. The cake will be slightly denser but still moist. For extra richness, fold in ½ cup coconut yogurt with the wet ingredients.
Can I use canned plums instead of fresh?
Yes, but drain and rinse the canned plums thoroughly to remove excess syrup. Chop them into ½-inch pieces and pat dry with a paper towel to prevent a watery cake. Add 1 extra tbsp lemon juice to the batter to balance the sweetness. For best results, use low-sugar canned plums or drain them for 10 minutes before using.
What's the best way to serve this cake?
Serve warm with a dusting of powdered sugar or a dollop of whipped cream. For extra flair, drizzle with warmed plum compote or a vanilla glaze**. Pair with Earl Grey tea or sparkling wine to complement the fruit flavors. The cake also makes a stunning dessert for holiday brunches or summer picnics—just pack slices in an insulated container.
