This almond flour plum cake delivers a perfect balance of nutty crunch and juicy plum bursts that will change how you think about gluten-free desserts.

I developed this recipe after years of experimenting with almond flour cakes—this version finally nails the crisp top and moist interior that makes it irresistible.

What sets this recipe apart is the way the almond flour's natural richness complements the plums' tartness, creating layers of flavor in every bite. The cake bakes up with a golden, slightly crisp top while remaining tender inside, and those plums burst with jammy intensity when you cut into it. This is the kind of dessert that feels special enough for company but simple enough for weeknight baking.

The beauty of this recipe lies in its versatility—it works beautifully as a standalone dessert or paired with whipped cream, and the almond flour makes it naturally gluten-free while still delivering that classic cake experience.

Ingredients for almond flour plum cake

The secret to this restaurant-quality plum cake lies in these 12 simple yet transformative ingredients.

Almond flour is the star here—Bob's Red Mill or Anthony's Goods are my go-tos for that ultra-fine grind. Fresh plums? Local farmers markets have the juiciest, but frozen work too (just thaw and pat dry). The butter matters—Plugrá or Land O'Lakes unsalted gives that perfect flakiness. I always double-check my almond extract is pure (no alcohol aftertaste)—McCormick or Frontier Co-op deliver every time. For the plums, Bing or Black Diamond varieties burst with flavor—avoid mealy ones like Red Heart.

No almond flour? Oat flour or cashew flour (blend raw cashews) works in a pinch, but texture will differ. Fresh plums unavailable? Pitted canned plums drained well (like Muir Glen) keep the jammy texture. The all-purpose flour might seem odd, but it's what creates that perfect structure—King Arthur is my brand of choice. Swapping the whipped cream? Coconut whipped cream (chilled coconut milk + powdered sugar) is a fantastic vegan alternative. The powdered sugar is purely for presentation—skip if you prefer it rustic.

Store the cake in an airtight container at room temperature for up to 3 days—it actually tastes better as the flavors meld. For longer storage, wrap tightly in plastic and refrigerate for 5 days. Freezing? Slice first, wrap individually, and freeze for 3 months. The plums release moisture, so always bake fresh batches when possible. Trust me, the first slice out of the oven is worth the wait—that crisp top gives way to jammy plum bursts that'll have everyone begging for seconds.

Step-by-step instructions for almond flour plum cake

This cake delivers a perfect balance of tender crumb, jammy plum bursts, and a nutty crisp top—here's exactly how to make it happen.

Preheat your oven to 350°F and line a 9-inch round cake pan with parchment paper. In a medium bowl, combine the 1.5 lbs fresh plums, 0.5 cup granulated sugar, and 1 tbsp vanilla extract. You want the plums to be coated evenly with sugar—this will help them caramelize beautifully during baking.

Transfer the plum mixture to a small baking dish and bake for 15-20 minutes until the plums are tender and the juices are thickened. You'll know they're ready when they release easily from the baking dish and the mixture has reduced slightly. Let the plum filling cool completely before using it in the cake—this prevents steam from making the cake dense.

In a large mixing bowl, cream together the 1 cup unsalted butter and 1 cup granulated sugar on medium speed until light and fluffy, about 3-4 minutes. This step is crucial—it incorporates air into the batter, which creates that lovely rise and tender texture. Scrape down the sides of the bowl with a spatula to ensure everything is well combined.

Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tbsp vanilla extract, 0.5 tsp almond extract, 2.5 cups almond flour, 0.5 cup all-purpose flour, 1.5 tsp baking powder, and 0.5 tsp salt. Mix on low speed just until everything is incorporated—you should still see some streaks of flour. Overmixing can make the cake tough, so be gentle here.

Pour half of the batter into the prepared cake pan. Using a spoon, spread the cooled plum filling evenly over the batter. This layering ensures each bite has that delightful plum surprise. Top with the remaining batter, spreading it evenly over the plum layer.

Bake the cake for 40-45 minutes until the top is golden brown and a toothpick inserted into the center comes out clean. The cake should spring back slightly when gently pressed in the center. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while allowing it to cook through.

Once the cake is done, remove it from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. While the cake cools, whip the 1 cup whipped cream with the 0.25 cup powdered sugar until soft peaks form. This light, airy topping complements the dense cake beautifully.

To serve, dust the top of the cake with powdered sugar and add dollops of the whipped cream. The contrast between the crisp top, tender crumb, and jammy plum bursts makes this cake truly special. Slice and enjoy immediately, or store in an airtight container in the refrigerator for up to 3 days.

Perfect pairings for this recipe

Creamy Pairings

This plum cake shines with vanilla bean ice cream—its cool sweetness balances the warm, jammy plums beautifully. I recommend Häagen-Dazs Vanilla Bean or Ben & Jerry's Phish Food for that creamy, dreamy texture. For a lighter option, coconut whipped cream (chilled coconut milk + powdered sugar) adds a tropical twist that complements the almond flour's nutty notes. 🥥

Fruit Companions

Fresh berries like raspberries or blackberries make a stunning contrast to the cake's richness. Toss them in a quick honey-sugar glaze (mix 2 tbsp honey with 1 tbsp lemon juice) and arrange them alongside slices. For a seasonal touch, peaches or nectarines (sliced and lightly caramelized) add a juicy, summery element that pairs perfectly with the plum's depth.

Warm Beverage Pairings

A cup of chai tea—especially Bigelow Earl Grey Chai—enhances the almond and plum flavors with its spiced warmth. For coffee lovers, a light roast (like Starbucks Cinnamon Dolce) keeps the palate clean without overpowering the cake's delicate sweetness. If you prefer something cozy, hot buttered rum (with a dash of cinnamon) becomes a festive match during colder months.

Unexpected Twists

Try pairing the cake with dark chocolate ganache—drizzle it over slices for a decadent contrast. I love using Ghirardelli 72% Dark Chocolate for its deep, bittersweet profile. Another fun idea: spiced nuts (toasted almonds with ½ tsp cinnamon and ¼ tsp cayenne pepper) add crunch and warmth. For a boozy touch, serve with plum brandy or a dry Riesling to elevate the fruit's natural flavors. ✨
