Desserts
This almond flour plum cake delivers a perfect balance of fruit-infused sweetness and nutty richness that will impress even the most discerning dessert lovers. The almond flour creates a tender yet sturdy crumb, while plums add natural sweetness and juicy bursts in every bite. I developed this recipe after years of experimenting with gluten-free baking, and it's become a staple at my dinner parties.
The secret to this cake lies in the proper preparation of the plums—pitting and slicing them just before baking ensures they release their juices without making the cake soggy. A simple syrup made with honey and water keeps the fruit moist while enhancing its natural flavors. The batter itself is a delicate mix of almond flour, eggs, and a touch of vanilla, creating a cake that's light yet substantial.
What you'll end up with is a beautifully golden cake with a tender crumb and juicy plum filling that stays moist for days. The almond flour gives it a subtle nutty flavor that pairs perfectly with the sweet-tart plums, creating a dessert that's both elegant and comforting. The cake's natural sweetness means you won't need extra frosting—just a dusting of powdered sugar if you prefer.
This recipe is perfect for summer gatherings, holiday desserts, or whenever you crave something special without the heaviness of traditional cakes. The combination of almond flour and plums makes it naturally gluten-free and lower in carbohydrates, yet it doesn't compromise on flavor or texture. Let's get baking!

Almond flour is the star here—Bob's Red Mill or Anthony's Goods are my go-tos for consistent texture. Grab the finest grind you can find, because coarser flour can make the cake dense. The plums? Fresh, ripe ones from a local market make all the difference—look for ones that yield slightly to gentle pressure. If you're using frozen plums, thaw and pat them dry first. The butter should be cold when you measure it—this keeps the cake tender. I always buy European-style butter with higher fat content for better flavor.
No almond extract? Vanilla bean paste at double the amount works in a pinch, though it won't be identical. The simple syrup is non-negotiable for keeping the plums juicy—don't skip it. For the flour, if you're strictly gluten-free, you can omit it entirely, but the cake will be slightly less stable. The baking powder should be fresh—if it's more than six months old, test it by mixing with water to see if it bubbles. And that powdered sugar? Confectioners' sugar from a sealed container prevents clumping. If you're worried about the cake being too sweet, remember the plums will balance it out.
This cake keeps beautifully—3 days at room temperature covered loosely with plastic, or 5 days in the fridge. For longer storage, wrap tightly and freeze for up to 3 months. I like to make it a day ahead so the flavors meld even more. The plums will get softer over time, so if you're serving it to guests, let it sit at room temperature for 30 minutes before slicing. The cake reheats wonderfully in the oven at 300°F for 10 minutes if you want to serve it warm.

Step-by-step instructions for almond flour plum cake
This cake delivers perfect fruit-infused moistness with a delicate crumb and nutty depth every time.
Prepare the Plum Filling and Simple Syrup
In a medium bowl, combine the 1.5 lb ripe plums that have been pitted and sliced into ¼-inch pieces with the 0.5 cup granulated sugar and 0.5 tsp almond extract. Toss gently to coat the fruit evenly. This sweetens the plums and enhances their flavor before baking.
In a small saucepan, combine the 0.25 cup water and 0.5 cup honey. Bring to a gentle boil over medium heat, then reduce heat to low and simmer for 3-4 minutes until slightly thickened. Remove from heat and stir in the 1 tbsp pure vanilla extract. This simple syrup will keep the plums juicy throughout baking.
Mix the Cake Batter
In a large mixing bowl, whisk together the 2.5 cups almond flour, 0.25 cup all-purpose flour, 1 tsp baking powder, and 0.5 tsp salt. This dry mixture forms the base of our cake. In a separate bowl, beat the 4 whole large eggs until just combined, then whisk in the 0.75 cup cold unsalted butter (cubed) until smooth.
Gradually add the dry ingredients to the wet mixture, alternating with the plum mixture and simple syrup. Mix on low speed just until combined—overmixing develops gluten and makes the cake dense. The batter should be thick but pourable, with visible plum pieces distributed throughout.
Bake the Cake to Golden Perfection
Preheat your oven to 350°F. Pour the batter into a 9-inch round cake pan lined with parchment paper. Bake for 40-45 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The cake should spring back slightly when gently pressed.
I like to tent the cake with foil after 25 minutes to prevent over-browning, especially if your oven runs hot. The internal temperature should reach 205-210°F—this ensures the almond flour is fully cooked and the texture is perfect.
Finish and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely. While still warm, dust the top generously with 0.25 cup powdered sugar using a fine-mesh sieve. This adds a delicate sweetness and enhances the almond flavor.
Slice into 8 equal wedges and serve at room temperature. The cake should have a moist, tender crumb with bursts of juicy plum throughout. For best results, serve within 2-3 days—the flavors deepen as it sits, but the texture remains best fresh.
Pro Tips For Making Almond Flour Plum Cake
- DON’T OVERMIX THE BATTER: Almond flour is sensitive—once you fold in the plums and eggs, stop after 10-12 strokes. I learned this the hard way when my cake turned dense and rubbery. Overworking it releases too much gluten from the eggs, and almond flour doesn’t bounce back like wheat flour.
- PEEL PLUMS AFTER COOKING: Raw plum skins can make the cake bitter and uneven in texture. Instead, poach the plums in honey and butter for 5-6 minutes until tender, then peel and chop them. The skins slip off easily, and the fruit stays juicy without sinking the batter.
- USE ROOM-TEMP BUTTER: Cold butter creates pockets in almond flour cakes, but if it’s too soft, the texture gets greasy. Take the butter out 30 minutes before mixing—it should dent when pressed but not melt. This guarantees a tender crumb without oiliness.
- BAKE UNTIL GOLDEN, NOT JUST SET: Almond flour cakes rely on color for doneness. Pull it out when the edges are deep golden (around 340°F internal temp), not just when the top looks set. I used to underbake mine, thinking they’d keep cooking—wrong. Overbaking dries them out fast.

Frequently asked questions
Can I substitute frozen plums for fresh?
Yes, but thaw them first and pat completely dry to prevent excess moisture in the cake. Frozen plums work well, but they release more liquid than fresh ones. For best texture, use 1.5 lb frozen plums that have been thawed overnight in the fridge.
Why is my almond flour cake dense?
Overmixing the batter or using coarse almond flour are common culprits. Mix just until combined and ensure your almond flour is finely ground. Also verify your baking powder is fresh—old leavening can prevent proper rise.
How do I make this cake egg-free?
Replace the 4 eggs with a flax egg mixture: combine 4 tbsp ground flaxseed with 10 tbsp water, let sit for 5 minutes to thicken. Add this to the batter along with 0.5 cup unsweetened applesauce for moisture. The texture will be slightly denser but still delicious.
Can I bake this in a different pan size?
For a 8-inch pan, reduce baking time by 5-7 minutes—check at 35 minutes. For a 10-inch pan, increase time by 5-7 minutes. Always use parchment paper and adjust temperature if needed (almond flour browns faster than wheat flour).
What's the best way to store leftovers?
Wrap tightly with plastic wrap and store at room temperature for 2 days, or refrigerate for up to 5 days. For longer storage, freeze slices in an airtight container for 3 months. Reheat individual slices in the oven at 300°F for 5-7 minutes to restore freshness.
