Ingredients for almond flour plum cake
Ten ingredients blend almond flour's richness with plums' natural sweetness for a moist, vibrant cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 ½ cups | Finely ground, unsweetened preferred |
| Fresh Plums 🍑 | 1 ½ lb | Pitted, sliced into 1/4-inch pieces |
| Granulated Sugar 🍚 | ¾ cup | Light brown preferred for depth |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for easier mixing |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar or bourbon |
| All-Purpose Flour 🌾 | ½ cup | For structure and binding |
| Baking Powder 🧂 | 1 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Simple Syrup 🍯 | ½ cup | Equal parts sugar and water |
The almond flour is the backbone here—Bob's Red Mill or Anthony's Goods are my go-tos for consistent texture. Look for finely ground, unsweetened varieties to avoid gritty bits. Fresh plums are non-negotiable; Italian prunes work in a pinch but lack that juicy burst. If using frozen, thaw and pat dry first. The butter should be cold when measuring—press into a cup and level off for accuracy. For the plums, Bing or Santa Rosa varieties hold their shape best when baked, but any firm, ripe plum will work.
No almond flour? Substitute with 2 cups oat flour (blend rolled oats), but expect a denser crumb. Running short on plums? Substitute with 1 cup dried plums (soaked in warm water for 15 minutes) plus an extra tablespoon of syrup. The simple syrup can be made ahead—just combine equal parts sugar and water, heat until dissolved, then cool. For a richer flavor, swap 1/4 cup of the granulated sugar for maple syrup. The baking powder must be fresh; if your stash is over a year old, test it by mixing with water—if it fizzes, it's good to go.
Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for 5 days to maintain moisture. For longer storage, wrap tightly in plastic and freeze for up to 3 months. The plums will soften further when reheated, so I recommend serving at room temperature. To refresh the cake, brush with a little warmed simple syrup before serving—it keeps the crumb tender and adds a glossy finish. Portion into individual slices for easy serving at gatherings.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this—just fold the almond flour into the butter until it crumbles like sand, then fold in the eggs and sugar. No electric mixer, no sticky mess, just a few minutes of gentle stirring. The texture comes out light and tender without the fuss.
- Plum Butter Magic: That caramelized plum filling? It’s the star. The sugar and butter melt into the fruit while baking, creating a jammy center that’s sweet but not cloying. Honestly, I’ve made this with frozen plums in a pinch, and it still delivers that same rich, fruity punch.
- Weeknight or Sunday Brunch: Slice it warm for breakfast with a dollop of whipped cream, or pack it for lunch—it holds up beautifully for days. Between us, I’ve even served it at potlucks when I forgot dessert. The almond crust stays moist, and the plums keep their shape, so it’s always a crowd-pleaser.
- Leftovers That Don’t Suck: Unlike regular cake, this stays fresh for days without drying out. I’ll be real: I’ve reheated slices in the oven with a little extra butter and called it a “dessert upgrade.” Plus, the almond flour is cheaper than flour these days, so you’re not breaking the bank for seconds.
Step-by-step instructions for almond flour plum cake
This method delivers a perfectly moist crumb with juicy plum bursts every time.
Prepare the Plum Filling and Simple Syrup
Pit and slice the 1.5 lb fresh plums into ¼-inch thick pieces. Toss them with 1 tablespoon of the granulated sugar to prevent browning. In a small saucepan, combine ½ cup simple syrup with the remaining ½ tablespoon granulated sugar and bring to a gentle simmer. Cook for 5 minutes until slightly thickened—this helps preserve the plums' juiciness during baking.
While the syrup simmers, arrange the plum slices in a single layer on a parchment-lined baking sheet. Brush lightly with the warm syrup mixture and let them sit at room temperature for 15 minutes. This pre-cooking step prevents the plums from releasing too much moisture into the cake batter, which could make it dense. The plums should look glossy and slightly softened but still firm to the touch.
Cream Butter and Sugar for Maximum Moisture
In a stand mixer fitted with the paddle attachment, beat the 1 cup cold unsalted butter (cut into cubes) with the ¾ cup granulated sugar on medium speed for 3-4 minutes. You're looking for a light, fluffy texture that nearly doubles in volume—the butter should look pale and airy. This step is crucial for creating a tender crumb in almond flour cakes, which can otherwise turn dry.
I like to scrape down the sides of the bowl every 30 seconds to ensure even mixing. The butter should leave clean streaks in the bowl when you lift the paddle. If the mixture feels too warm or melts prematurely, chill the bowl in the freezer for 5 minutes before continuing. The goal is to incorporate air while keeping the butter firm enough to hold its structure during baking.
Combine Wet Ingredients and Fold in Dry Components
Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then add the 1 tablespoon vanilla extract and mix for another 10 seconds. Remove the bowl from the mixer and set aside. The batter will look slightly thick and curdled at this stage—that's normal and will smooth out when you add the dry ingredients.
In a separate bowl, whisk together the 2.5 cups almond flour, ½ cup all-purpose flour, 1 teaspoon baking powder, and ½ teaspoon salt. Gently fold this dry mixture into the wet ingredients using a silicone spatula, mixing just until combined. Avoid overmixing—you should still see small streaks of flour. The batter will be thick and slightly sticky, similar to cookie dough. This texture is ideal for maintaining moisture during baking.
Layer and Bake for Even Cooking
Preheat your oven to 350°F and grease a 9-inch round cake pan (or line it with parchment paper). Spread half of the batter evenly into the prepared pan, creating a smooth surface. Arrange half of the plum slices in a single layer over the batter, slightly overlapping them. Pour the remaining batter over the plums, then top with the remaining plum slices. Gently press down to ensure good contact between layers.
Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and slightly pulled away from the edges of the pan. If the top browns too quickly, tent loosely with aluminum foil after 25 minutes to prevent over-browning while allowing the center to cook through. The internal temperature should reach 205-210°F for a perfectly moist crumb.
Finish with Syrup and Rest Before Serving
Immediately after removing the cake from the oven, poke holes all over the top with a skewer or toothpick. Slowly pour the remaining ½ cup simple syrup over the cake, letting it absorb into the holes. This step ensures the cake stays moist and adds a subtle sweetness that balances the tartness of the plums. Let the cake cool in the pan for 15 minutes, then transfer it to a wire rack to cool completely.
The cake will firm up as it cools, but the plums will remain tender and juicy. Serve slices at room temperature for the best texture—each bite should deliver a perfect balance of nutty almond flavor, sweet plum bursts, and a tender crumb. For extra presentation, dust with powdered sugar or serve with a dollop of whipped cream. This cake keeps well at room temperature for 3 days or can be refrigerated for up to 5 days (bring to room temperature before serving).
Pro Tips For Making Almond Flour Plum Cake
- CHILL THE DOUGH: Almond flour is temperamental—it dries out fast. After mixing your batter, pop it in the fridge for 20-30 minutes. I learned this the hard way when my first attempt spread like pancake batter. Cold dough holds its shape better, and the plums stay juicy instead of sinking into a sad, flat mess.
- PIT THOSE PLUMS: Skip the whole fruit if you want a clean bite. Pitting and quartering plums (skin on) keeps your cake from turning into a mushy plum soup. Toss them in a little sugar while you work—they’ll release juices that caramelize beautifully. (Yes, even if you’re impatient like me, resist the urge to skip this.)
- WEIGH YOUR FLOUR: Scooping almond flour by volume is a disaster. It packs differently than all-purpose flour, and your cake will either be too dense or too dry. Use a kitchen scale—300g is your target. I was skeptical until I tried it; the texture became light and tender instead of brick-like.
- BAKE LOW AND SLOW: Almond flour cakes need patience. Bake at 325°F (not 350°F) and check at 40 minutes—it’s done when the edges are golden but the center still jiggles slightly. Overbaking turns them into almond-flour hockey pucks. A toothpick test works, but don’t trust it blindly; almond cakes stay moist longer.
Best sauces and condiments for this dish
Plum Compote
Skip the cake entirely and serve this plum compote as a standalone dessert or over vanilla ice cream. Simmer 1.5 lb fresh plums (pitted and sliced) with ¼ cup granulated sugar, 1 tbsp lemon juice, and 1 tsp vanilla extract until softened (15-20 minutes).
Mash slightly with a fork for texture. The natural sweetness of the plums shines when paired with a scoop of homemade almond milk ice cream—the nutty flavor complements beautifully. 🍑
Lemon Curd Drizzle
Brighten the cake with a tangy lemon curd drizzle that cuts through the richness. Make a simple curd by whisking ½ cup lemon juice, ½ cup sugar, 3 egg yolks, and ¼ cup butter over low heat until thickened (8-10 minutes).
Strain, then drizzle over slices while warm. The acidity enhances the plums' flavor while adding a silky finish. Store leftovers in the fridge for up to 5 days. 🍋
Whipped Almond Cream
Replace traditional whipped cream with whipped almond cream for a nutty twist. Whip 1 cup heavy cream with 2 tbsp powdered sugar and 1 tsp almond extract until soft peaks form.
Fold in 2 tbsp crushed almonds for texture. This lighter alternative pairs perfectly with the cake's almond flour base. Serve immediately for the fluffiest consistency. 🌰
Spiced Honey Glaze
Add warmth with a spiced honey glaze that caramelizes beautifully. Heat ¼ cup honey, 1 tbsp butter, ½ tsp cinnamon, and a pinch of cardamom in a saucepan until bubbly (3 minutes).
Drizzle over cake slices while still warm. The honey enhances the plums' natural sweetness, while the spices add depth. Store glaze in the fridge for up to 1 week. 🍯
Vanilla Bean Mascarpone
Elevate your serving with vanilla bean mascarpone. Mix ½ cup mascarpone cheese, 2 tbsp powdered sugar, and the seeds from 1 vanilla bean until smooth. Dollop alongside cake slices for a creamy contrast.
The vanilla complements the almond flour's nuttiness, while the mascarpone adds a luxurious texture. Use within 3 days for best flavor. 🌿

Frequently asked questions
Can I substitute dried plums for fresh in this recipe?
Yes, but adjust the preparation method. Use 1 cup dried plums (about 6 oz) and soak them in warm water for 15 minutes to rehydrate. Drain well and chop into small pieces before using. Add 1 extra tablespoon of simple syrup to compensate for their concentrated sweetness. The texture will be slightly denser than with fresh plums, but the flavor remains rich.
Why does my almond flour cake turn out dry?
<The most common causes are overbaking or not using enough moisture. Almond flour absorbs liquid differently than wheat flour, so avoid baking beyond 40-45 minutes—check with a toothpick at 35 minutes. For extra moisture, try adding 1 extra tablespoon of simple syrup to the batter or brushing the top with syrup after baking. Cold butter and proper mixing are also key—cream the butter and sugar until pale and fluffy.
Can I make this cake gluten-free?
This recipe is already gluten-free since it uses almond flour and all-purpose flour only for structure. For a 100% gluten-free version, replace the ½ cup all-purpose flour with ½ cup gluten-free 1:1 baking flour (like Bob's Red Mill). Test your gluten-free flour blend first to ensure proper rise—some brands need an extra ¼ teaspoon xanthan gum for binding.
How do I store leftovers to keep them moist?
Store the cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for 5 days or freeze for 3 months. To refresh stale slices, brush with warmed simple syrup and let sit for 10 minutes before serving. Avoid plastic wrap—it traps moisture and can make the cake soggy. For best texture, bring refrigerated cake to room temperature before serving.
What's the best way to reheat sliced cake?
For individual slices, warm in the microwave for 10-15 seconds on 50% power to soften the crumb without drying it out. For a whole cake, wrap tightly in foil and warm at 300°F for 10 minutes. Never reheat uncovered—this causes moisture loss. The plums will soften further, so serve immediately after warming for the juiciest experience.
