Old Fashioned Yogurt Plum Cake

Ever wonder why some cakes feel like a dry sponge while others feel like a warm hug from your grandmother? It usually comes down to the fat and the acid. Plums are a bit of an overlooked fruit in the baking world, but when they roast in a batter, they turn into these little pockets of jam.

I remember my aunt used to make a version of this back home. She didn't use a scale, just a "pinch of this" and a "handful of that," but the smell of cinnamon and baking fruit always filled the whole house. It's the kind of dessert that makes a house feel like a home.

You can expect a Yogurt Plum Cake that is dense yet soft, with a golden crust. It isn't a fancy, layered cake, but that's the point. It's honest, rustic, and relies on the natural sweetness of the fruit to do the heavy lifting.

Yogurt Plum Cake

The real trick to this cake is the yogurt. Most people use milk or sour cream, but Greek yogurt gives the crumb a specific weight that keeps the plums from sinking straight to the bottom.

Yogurt Acidity: The acid in the yogurt reacts with the baking powder to create a steady lift. This keeps the cake tender without needing tons of butter.

Plum Placement: Pressing the fruit in a pattern prevents them from clustering in one spot. This ensures every slice has a bit of tart jamminess.

What Each Ingredient Brings

I don't believe in overcomplicating things. We use a few staples that you probably already have in the pantry.

Gathering Your Essentials

For this Yogurt Plum Cake, you'll need items that provide a balance of sweetness and acidity. I prefer using full fat Greek yogurt because the fat carries the flavor of the vanilla and cinnamon much better.

• 1.5 cups (190g) all purpose flour Why this? Standard protein for a sturdy but soft crumb
• 0.75 cup (150g) granulated sugar Why this? Dissolves easily into the wet ingredients
• 1 tsp (5g) baking powder Why this? Provides the necessary lift
• 0.5 tsp (3g) salt Why this? Balances the sweetness of the plums
• 1 cup (240g) plain Greek yogurt Why this? Creates a tender, moist texture
• 0.5 cup (120ml) vegetable oil Why this? Ensures the cake stays moist for days
• 2 large (100g) eggs Why this? Binds the batter and adds structure
• 1 tsp (5ml) vanilla extract Why this? Classic aromatic base
• 0.5 tsp (1g) ground cinnamon Why this? Complements the plum flavor
• 5 medium (300g) plums, pitted and sliced Why this? Natural tartness
• 1 tbsp (12g) granulated sugar Why this? For the caramelized topping
• 1 tbsp (15g) melted butter Why this? To prevent sticking

Tools for the Job

You don't need a fancy stand mixer for this. A large mixing bowl and a sturdy spatula will do the trick. I use a 9 inch springform pan because it makes it much easier to get the cake out without it breaking.

If you don't have a springform pan, a standard cake pan works, but you'll need to be more careful with the greasing. Make sure you have a piece of parchment paper for the bottom. This is the only way to be sure the cake doesn't stick to the base.

How to Bake the Cake

The flow here is simple. We mix the dry, add the wet, and then arrange the fruit.

Phase 1: Preparing the Base

1. Preheat oven to 350°F (175°C). Grease a 9 inch springform pan with melted butter and line the bottom with parchment paper.
2. In a large bowl, whisk together the flour, 150g sugar, baking powder, salt, and cinnamon until no lumps remain. Note: Whisking the flour aerates it for a lighter cake
3. Create a well in the center of the dry ingredients and add the Greek yogurt, vegetable oil, eggs, and vanilla extract.
4. Using a spatula, gently fold the wet and dry ingredients together until no streaks of flour remain. Stop mixing as soon as it's combined to avoid a rubbery texture.

Phase 2: Adding the Fruit

5. Cut plums into uniform 1/4 inch rounds.
6. Pour the batter into the prepared pan and smooth the top.
7. Press the plum slices gently into the batter in a concentric circle pattern. Note: Don't push them all the way down or they'll sink
8. Sprinkle the top of the plums with 1 tbsp of granulated sugar.

Phase 3: The Bake

9. Bake for 45 minutes until a toothpick inserted into the center comes out clean.
10. Let it cool in the pan for 10 minutes before releasing the sides.

Chef's Note: If you love a bit of a crunch, you can add a handful of sliced almonds on top with the sugar. It adds a nice contrast to the soft fruit.

Fixing Common Baking Hiccups

Baking can be finicky, but most issues have a simple cause. If your cake feels off, it's usually about temperature or mixing.

Troubleshooting Common Issues

Adjusting the Batch Size

You can easily change the size of this Yogurt Plum Cake depending on who is coming over.

Scaling Down (Half Batch): Use a 6 inch pan and reduce the baking time by about 20%. For the egg, crack one into a bowl, beat it, and use half of the liquid.

Scaling Up (Double Batch): I recommend baking two separate cakes rather than one giant one. If you use a deeper pan, lower the oven temperature to 325°F and extend the bake time. Don't double the salt or cinnamon fully; 1.5x is usually enough to keep the flavors balanced.

If you find you have too much batter, you can use the leftover mix to make a few individual cupcakes. They'll bake much faster, usually in about 18-22 minutes. For other fruit based treats, my Homemade Banana Muffins use a similar mixing method.

Baking Tales That Aren't True

You might hear that you need to sift your flour every single time for a cake to be light. While it helps, a good whisking of the dry ingredients does the same thing for this specific recipe.

Another one is that the eggs must be room temperature. While it helps the batter emulsify a bit better, it won't ruin this cake. The Greek yogurt is thick enough to handle cold eggs without the batter breaking.

Storing and Saving Your Cake

This cake stays moist for a long time because of the oil and yogurt.

Storage: Keep it in an airtight container at room temperature for 2 days. In the fridge, it will last up to 5 days. If you refrigerate it, the crumb firms up, which some people actually prefer.

Freezing: You can freeze individual slices. Wrap them tightly in plastic wrap and then foil. They'll stay good for 3 months. To eat, just thaw in the fridge overnight or pop a slice in the microwave for 20 seconds.

Zero Waste: If you have leftover plum halves that didn't make it into the cake, simmer them with a bit of sugar and lemon juice to make a quick compote. This tastes great spooned over a fresh slice of the cake.

Best Ways to Serve This

A Yogurt Plum Cake is great on its own, but a few additions can make it feel special.

The Classic Pairing A dollop of whipped cream or a scoop of vanilla bean ice cream balances the tartness of the plums. If you're in the mood for something even more decadent, you might enjoy Mini Oreo Cheesecakes for a different kind of treat.

The Beverage Match Black coffee or a strong Earl Grey tea are the best matches here. The bitterness of the drink cuts through the richness of the yogurt and the sweetness of the caramelized plums.

Reheating Tips If the cake has been in the fridge, let it sit at room temperature for 30 minutes. If you want that "just out of the oven" feel, warm a slice in a toaster oven for 3 minutes. It softens the butter in the crumb and makes the plums jammy again.
