As I have written about in previous posts, this is one of my favorite times of year. The ime of year when summer fruits meet autumn baking. It's like a little acknowledgment of what's to come. This spiced streusel plum cake combines a touch of fall aromatics and textures with beautifully ripe late summer fruit.
This spiced plum cake is made from a lightly spiced vanilla cake topped with layers of tart plums and crunchy spiced walnut streusel. With layers of beautifully balanced flavors and contrasting textures, this cake is simple, unfussy and pairs perfectly with a cup of coffee.
In a few words, this plum cake is

Tips and tricks for a perfectly delicious spiced streusel plum cake
Best substitutions for this recipe:
- All purpose flour: for a gluten free option, I recommend
- Cake flour: Make a DIY version using all purpose flour and cornstarch.
- See recipe notes for how to do this.
- Plums: we are currently in prime stone fruit season so substitute with any stone fruit or berries.
- Use fresh fruit when possible. If youre using frozen, leave the fruit frozen and bake for additional time as needed (up to 10-20 minutes).
- Lemon zest, ground cinnamon and cardamom: These are all flavor enhancers.
- I highly recommend using all if you can. If not, you can easily use all cinnamon or ginger or use a pre-made pumpkin spice or chai spice .
- Sugar: You can use an alternative sugar if its one you baked with already.
- I LOVE using maple sugar
- Buttermilk try to use what a store bought version, but if needed use the DIY version in found in the recipe notes.
Tips and tricks for this spiced streusel plum cake:
- Read through the recipe before starting.
- Use a “light hand” when folding the ingredients together.
- Look for the signs the cake is done rather than sticking strictly to the baking times listed in the recipe.
- The sides will pull gently from the edges of the pan.
- If it looks wet, the cake will need about 10-20 minutes from that point.
- The top will be golden brown, but not burned.
- A toothpick inserted into the center will come out with a few moist crumbs.
- If the toothpick come out “gummy” with a few crumbs, it needs 5-10 more minutes.
- Cool the cake in the pan on a cooling rack for 20 minutes.
- Cool the cake to room temperature on a cooling rack.
- Dust with powdered sugar or leave plain. You could also use the delicious lemon maple glaze.
Do I need to add the streusel topping?
This is totally up to you! I love adding streusel to everything possible, but this spice cake is equally delicious and even more beautiful by leaving the topping off. If you want to omit the streusel topping:
- Find the prettiest plums you can (the deep, ruby red ones are my favorite).
- Slice them a little thicker. Aim to get 4-6 slices per plum.
- Lightly press them into the top of the cake batter.
- Sprinkle a nice layer of granulated or demerara sugar on top.
- Bake as noted in the recipe, but start checking for doneness at the 40 minute mark.

Instructions
spiced walnut streusel

spiced plum cake
- Preheat the oven to 350F (177C). Line a 9" (23cm) springform pan with parchment paper, along the bottom. Lightly grease the sides of the pan. Set aside. If making your own buttermilk, add 2 tsp lemon juice to the 1/2 c room temperature whole milk now. It needs about 10 minutes to curdle.
- In a medium size mixing bowl, whisk together the cake flour, all purpose flour, baking soda, baking powder, ground cardamom, ground cinnamon and salt. Set aside.
- Zest the lemon into a small bowl filled with sugar. Rub the sugar and zest together until a wet sand like texture forms.
- Using a whisk (by hand) or electric mixer with beaters or paddle attachment, beat together the oil and butter together until smooth and well combined.
- With the mixer on low, slowly stream in the lemon sugar into the oil butter mixture untill all the sugar is added. Increase the speed to mediumm, beating until the mixture is light and fluffy, about 2-3 minutes.
- Add eggs and vanilla extract, beating each one for about 20 seconds on medium speed before adding the next.
- Stir in the dry ingredients and buttermilk to the wet, alternating in this order: dry, buttermilk, dry, buttermilk, dry. Leave a few flour or milk streaks before adding the next .
- Pour batter into the prepared pan. Smooth the top of the batter. Top with sliced plums.
- Top the batter with the chilled streusel topping. Feel free to clump pieces together for larger crumbles or scatter smaller pieces over the top of the batter. Gently press the struesel into the cake batter and plums.
- Bake at 350 F (177C) for 50-60 minutes. Around 45 minutes, do the first check of the cake. Check to make sure the struesel isn't burning. If the top is browning too much, place a tent foil over the top for the remainder of the time. Bake an additional 5 minutes before checking for doneness. The edges of the cake will have pulled slighly from the pan and a toothpick inserted into the center will come out clean or with a few moist crumbs. If the toothpick comes out wet or "gummy," check every 5-10 until done.
- Remove the plum cake from the oven to cool in the pan for 30 minutes.
- Cool the cake an additional 30-45 minutes on the cooling rack if desired. Top with a dusting of powdered sugar, slice and enjoy!
Notes
cake flour: to make your own DIY cake flour, measure out 1 c all purpose flour. scoop out 2 tbsp flour. add back in 2 tbsp cornstarch. sift together 3-4 times.
buttermilk: to make your own DIY buttermilk, measure out 1/2 c milk. add in 2 tsp lemon juice. mix together. let sit for 10 minutes to curdle.
ground cardamom: this spice is so lovely when paired with plums. if you don't like cardamom or simply don't have any on hand, feel free to use ground ginger or extra ground cinnamon. if using either of these as a substitute for the cardamom, use double the amount of cardamom ( 1/2 tsp | 1 tsp instead of 1/4 tsp | 1/2 tsp).
