Streusel Plum Cake: A Taste of Late Summer

There’s something magical about the late summer months, when the air is thick with the scent of ripening fruit. As a child, I remember eagerly anticipating the arrival of my grandmother’s plum tree, heavy with its jewel-toned bounty. One of her signature recipes, passed down from generations, was a simple yet exquisite plum cake, crowned with a buttery, cinnamon-spiced streusel. The first bite of the warm cake, the tart plums yielding to the sweet crumble, always felt like a warm hug. To this day, that flavor combination instantly transports me back to her sun-drenched kitchen.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 35-45 minutes
• Total Time: 55-65 minutes
• Servings: 10
• Yield: 1 cake
• Dietary Type: Low-Fat

Ingredients

• 3/4 cup granulated sugar
• 1/4 cup soft margarine
• 2 eggs, separated
• 1 1/2 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 cup 2% low-fat milk
• 2 (14 ounce) cans plums, drained (or 2 cups halved ripe plums)

Streusel Topping

• 1/2 cup packed brown sugar
• 1 tablespoon soft margarine
• 1 teaspoon cinnamon

Glaze (optional)

• 1/4 cup icing sugar (optional)
• 1 teaspoon milk (optional)
• 1/4 teaspoon vanilla (optional)

Equipment Needed

• Large mixing bowl
• Small mixing bowl
• 9-inch square cake pan
• Electric mixer (optional, but recommended)
• Measuring cups and spoons
• Rubber spatula or wooden spoon

Instructions

1. Preheat your oven to 350°F (175°C). Grease a 9-inch square cake pan thoroughly to prevent sticking.
2. In a large bowl, cream together the granulated sugar, soft margarine, and egg yolks until the mixture is light and fluffy. This step is crucial for creating a tender cake crumb, so take your time. An electric mixer will make this process easier, but you can certainly do it by hand.
3. In a separate bowl, combine the all-purpose flour and baking powder. Whisk them together to ensure the baking powder is evenly distributed.
4. Gradually beat the flour mixture into the egg mixture in the large bowl, alternating with the low-fat milk. Begin and end with the flour mixture. This helps prevent the gluten in the flour from developing too much, which can result in a tough cake. Mix until just combined; avoid overmixing.
5. In a clean bowl, beat the egg whites until they form stiff, but not dry, peaks. It’s important that the bowl and beaters are grease-free for the egg whites to whip properly.
6. Gently fold the beaten egg whites into the batter. This step adds lightness and airiness to the cake. Be careful not to deflate the egg whites; fold them in using a gentle over-and-under motion.
7. Pour the batter into the prepared greased 9-inch square cake pan, spreading it evenly.
8. If using canned plums, ensure they are thoroughly drained. If using fresh plums, halve and pit them.
9. Arrange the plum halves over the batter in the pan, pressing them gently into the surface. You can create a decorative pattern or simply scatter them evenly.
10. Streusel Topping: In a small bowl, combine the packed brown sugar, soft margarine, and cinnamon. Mix with your fingers or a fork until the mixture resembles coarse crumbs.
11. Sprinkle the streusel topping evenly over the plums.
12. Bake in the preheated oven for 35-45 minutes, or until the top is golden brown and a tester (toothpick or cake tester) inserted into the center of the cake comes out clean.
13. Let the cake cool slightly in the pan before transferring it to a wire rack to cool completely.
14. Glaze (optional): In a small bowl, combine the icing sugar, milk, and vanilla (if using). Whisk until smooth.
15. Once the cake is cooled, drizzle the glaze over the top, if desired.

Expert Tips & Tricks

• For a richer flavor, consider browning the butter for the streusel topping before mixing it with the brown sugar and cinnamon. Just be sure to let it cool slightly before incorporating it.
• If you’re using fresh plums that are very juicy, you can toss them with a tablespoon of flour before arranging them on the batter. This will help absorb excess moisture and prevent the cake from becoming soggy.
• To prevent the streusel from browning too quickly, you can tent the cake loosely with aluminum foil during the last 15 minutes of baking.
• If you don’t have soft margarine on hand, you can use melted butter instead. Just be sure to let it cool slightly before adding it to the batter or streusel.
• The cake is best enjoyed the day it’s baked, but it will still be delicious for a few days if stored properly.

Serving & Storage Suggestions

Serve the streusel plum cake warm or at room temperature. It’s delicious on its own, but you can also serve it with a scoop of vanilla ice cream or a dollop of whipped cream. For a truly decadent treat, try pairing it with a glass of dessert wine or a cup of strong coffee.

To store, wrap the cake tightly in plastic wrap or place it in an airtight container. It will keep at room temperature for up to 2 days, in the refrigerator for up to 4 days, or in the freezer for up to 2 months. To reheat, warm in a low oven (around 300°F/150°C) for 10-15 minutes, or microwave individual slices for a few seconds.
