| Ingredient | Amount | Notes |
|---|---|---|
| Almond Flour 🌰 | 2 ½ cups | Finely ground, unsweetened |
| Fresh Plums 🍑 | 2 cups | Pitted, halved, juicy variety |
| Granulated Sugar 🍚 | 1 cup | Light brown preferred |
| Unsalted Butter 🧈 | ¾ cup | Softened, room temperature |
| Large Eggs 🥚 | 3 whole | Room temperature, beaten |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Lemon Zest 🍋 | 1 tbsp | Freshly grated |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |

The almond flour is the star here—Bob's Red Mill or Anthony's Goods are my go-tos for consistent texture. Look for finely ground (not coarse) and unsweetened—those little details make a huge difference. Plums are non-negotiable for that jammy center, but fresh, in-season fruit is key. If you can't find ripe plums, blueberries or peaches work in a pinch. The butter should be softened but not melted—press your finger into it and it should leave a slight indent. Room-temperature eggs blend smoother, so take them out 30 minutes before baking.
No almond flour? Oat flour or coconut flour can replace it, but you'll need to adjust liquids—add 2 tbsp extra liquid per 1 cup substitute. Fresh plums too tart? Toss them with 1 tsp sugar before adding to the batter. The vanilla extract matters—imitation stuff won't cut it here. For a deeper flavor, infuse the butter with vanilla bean while it softens. The all-purpose flour might seem odd in a gluten-free recipe, but it gives that lift traditional cakes have. Skip it if you're strictly gluten-free, but your cake will be denser. Powdered sugar for dusting? Confectioners' sugar is the only way—it dissolves beautifully.
This cake keeps beautifully—3 days at room temperature wrapped tightly, or 5 days in the fridge. For longer storage, freeze slices between parchment paper for up to 3 months. The plums get even more jammy after a day or two, so make it ahead if possible. Reheat slices for 10 seconds in the microwave to revive the texture. I always make a double batch—one for dinner guests, one for breakfast the next morning. The almond slices on top add crunch, but they're optional if you're in a hurry.
Why You'll Love This Recipe

- Plum-Butter Magic: That buttery richness from the almond flour and fresh plums? It’s like summer in a slice—juicy bursts with a tender crumb that doesn’t turn to mush. Honestly, the first bite makes me forget it’s "healthy" (whatever that means).
- Weekend or Weeknight: Slice it warm for brunch with coffee, or pack it in lunchboxes—it holds up for days without drying out. I’ve served it at picnics, potlucks, and even as a "dessert" for my kids’ school bake sales. (They never notice it’s not store-bought.)
- Leftovers? More Like Leftovers: This cake actually improves overnight—moister, richer, and perfect for breakfast toast. I make a double batch on Sundays and still have slices by Thursday. Plus, almond flour stretches my budget further than regular flour ever did.
Step-by-step instructions for almond flour plum cake
Here's how to create a moist, tender cake with bursts of juicy plums—every bite is pure summer magic.
Prepare the Plums and Prep the Pan
Start by pitting and halving the 2 cups fresh plums, then arrange them cut-side down in a 9-inch round cake pan lined with parchment paper. This creates a beautiful fruit layer while preventing a soggy bottom. Press down gently to ensure even contact with the pan.
Preheat your oven to 350°F while you work. I like to use a light spray of nonstick cooking spray on the parchment before adding the plums—this makes removal effortless later. The plums will release their juices as they bake, infusing the cake with natural sweetness and moisture.
Mix the Wet Ingredients for a Silky Batter
In a large mixing bowl, combine the 0.75 cup softened unsalted butter and 1 cup granulated sugar. Beat with an electric mixer on medium speed for 2-3 minutes until light and fluffy. This step is crucial—it incorporates air that will create a tender crumb.
Add the 3 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon vanilla extract and 1 tablespoon lemon zest. The lemon zest adds a bright citrus note that balances the sweetness of the plums. Mix until just combined—no need to overwork the batter.
Combine Dry Ingredients for Structure
In a separate bowl, whisk together the 2.5 cups almond flour, 0.25 cup all-purpose flour, 1 teaspoon ground cinnamon, and 0.5 teaspoon salt. Sift the mixture directly into the wet ingredients and mix on low speed until just combined. I use a spatula to fold in the last bits—this prevents overmixing, which can make the cake dense.
Pour the batter over the plums in the prepared pan, spreading it evenly. The batter should reach about ¾ of the way up the pan, leaving room for the plums to release their juices without overflowing. Gently press down on the batter to ensure the plums stay in place.
Bake Until Golden and Juicy
Place the cake pan in the preheated 350°F oven and bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted near the center comes out clean. The cake should spring back slightly when pressed gently in the center—this indicates doneness.
Here's the thing—don't overbake. The plums will continue releasing juices as the cake cools, so it's better to pull it out a little early if needed. The cake should be moist but not gummy. Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Dust and Garnish for Elegance
Once completely cooled, dust the top of the cake with 0.25 cup powdered sugar using a fine-mesh sieve for an elegant finish. The powdered sugar adds a delicate sweetness and makes the cake look stunning.
Arrange the 0.25 cup almond slices on top in a decorative pattern. I like to fan them out slightly so they catch the light. Serve slices at room temperature—this is when the cake reaches its peak texture, with a tender crumb and juicy plum bursts in every bite.
Pro Tips For Making Almond Flour Plum Cake
- Weigh Your Almond Flour: Scooping almond flour from the bag packs in air pockets—your cake will be dense and dry. Use a kitchen scale for precise measurements (1 cup = ~120g) and spoon it into the bowl without pressing down. I learned this the hard way after a cake that looked perfect but tasted like a brick. ---
- Poke the Plums: Skip the whole pits-out hassle—just slice the plums and poke each piece with a paring knife. This keeps their shape while letting them soften faster in the batter. (Yes, even if you’re impatient like me, resist the urge to skip this.) ---
- Cream Butter Slowly: Almond flour batters are forgiving, but don’t rush the butter-egg-sugar mix. Cream the butter and sugar on medium-low for 2-3 minutes until just pale—no need to overwork it. Overmixing here makes the cake gummy, and nobody wants that. ---
- Test for Doneness Early: Almond flour cakes set faster than wheat-flour ones. Start checking at 25 minutes with a skewer—if it comes out clean, pull it. Overbaking dries out the plums and turns the crust bitter. (Your future self will thank you for not letting it turn into a science experiment.)
Make-ahead tips for almond flour plum cake
Prep Ahead Strategy
Make the batter the night before and store it in an airtight container in the fridge. The flavors meld beautifully overnight, and you'll save 15 minutes of prep time on baking day. Just whisk it briefly to recombine before pouring over the plums. I always do this—it's a game-changer for busy mornings. 💫
Plum Prep Shortcut
Buy pre-pitted frozen plums from the grocery store to skip the tedious pitting process. Thaw them overnight in the fridge, then proceed with the recipe as written. The texture remains perfect, and you'll avoid the mess of pits everywhere. This works especially well if you're making the cake for a holiday gathering.
Freezer-Friendly Slices
Slice the cake once fully cooled and wrap individual portions in plastic wrap, then place them in a freezer bag for up to 3 months. To serve, thaw at room temperature for 1 hour or warm for 10 seconds in the microwave. The texture stays moist, and the plums remain juicy—just like fresh-baked. 🍑
Make-Ahead Garnish
Toast the almond slices in advance by spreading them on a baking sheet at 350°F for 5-7 minutes** until golden and fragrant. Store in an airtight container at room temperature for up to 1 week. This saves time on baking day and adds a professional touch to your presentation.
Overnight Storage Secrets
Store the fully baked (but undusted) cake in an airtight container at room temperature for up to 3 days. The plums continue to release juices, making each slice even more flavorful. For longer storage, wrap the whole cake in plastic and refrigerate for up to 5 days. Always dust with powdered sugar just before serving to keep it looking fresh. ✨
Batch Baking Tips
Double the recipe and bake two 9-inch cakes simultaneously in separate pans. This is perfect for parties or when you know you'll have leftovers. Use a cookie sheet to elevate one pan if your oven has limited space. The cakes will bake evenly, and you'll have perfect slices ready for days. I always make two—one for guests, one for my breakfast table! 🍰

Frequently asked questions
Can I substitute other fruits instead of plums?
While plums create that signature jammy center, peaches, blueberries, or cherries work beautifully too. For stone fruits, pit and halve them like plums. Berries should be tossed with 1 tablespoon sugar first to prevent sinking. Adjust baking time by 5-10 minutes if using denser fruits like peaches.
Why does my almond flour cake turn out dense?
Overmixing is the #1 culprit—almond flour absorbs liquid differently than wheat flour. Mix just until combined (about 20 strokes with a spatula). Also ensure your almond flour is finely ground and not clumpy. Another tip: don't skip the all-purpose flour—it adds necessary structure to prevent density.
How do I make this recipe egg-free?
Replace the 3 eggs with a flax egg mix: combine 3 tablespoons ground flaxseed with 9 tablespoons water, let sit for 5 minutes to thicken. For extra moisture, add 2 tablespoons applesauce to the wet ingredients. The texture will be slightly denser but still delicious!
Can I bake this in a different pan size?
Yes! For a 8-inch pan, reduce baking time by 5-7 minutes (check at 35 minutes). For a 10-inch pan, increase batter by 25% and bake 5-7 minutes longer. Line all pans with parchment for easy removal. The key is maintaining a 2-inch deep batter layer for even baking.
What's the best way to serve leftover slices?
Warm slices for 10-15 seconds in the microwave to revive the texture, then serve with vanilla ice cream or a drizzle of warm plum compote. For breakfast, toast slices lightly and top with Greek yogurt and extra almond slices. The cake's natural sweetness makes it perfect for dessert or brunch!
