Ingredients:
- For the Cake:
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup (2 sticks) unsalted butter, softened
- 1 3/4 cups granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- For the Strawberry Rhubarb Filling:
- 4 cups chopped rhubarb (about 1 pound)
- 2 cups chopped fresh strawberries
- 3/4 cup granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon lemon zest
- 1 tablespoon lemon juice
- For the Crumble Topping:
- 1 cup all-purpose flour
- 1/2 cup packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 cup (1 stick) cold unsalted butter, cut into small pieces
- Optional Glaze:
- 1 cup powdered sugar
- 2-3 tablespoons milk or lemon juice
Preparing the Strawberry Rhubarb Filling:
- Combine the Fruits: In a large bowl, gently mix together the chopped rhubarb and strawberries. I like to use a bowl that gives me plenty of room to toss without making a mess.
- Add Sweetness and Thickener: In a separate small bowl, whisk together the 3/4 cup of granulated sugar and the cornstarch. This ensures the cornstarch is evenly distributed and prevents clumps in the filling.
- Zest and Juice It Up: Add the lemon zest and lemon juice to the sugar and cornstarch mixture. The lemon zest adds a bright, aromatic note, while the lemon juice enhances the flavors of the strawberries and rhubarb.
- Combine Everything: Pour the sugar mixture over the rhubarb and strawberries. Gently toss everything together until the fruit is evenly coated. Be careful not to mash the strawberries.
- Set Aside: Let the filling sit for about 15-20 minutes while you prepare the cake batter and crumble topping. This allows the sugar to draw out some of the juices from the fruit, creating a luscious sauce.
Making the Crumble Topping:
- Combine Dry Ingredients: In a medium bowl, whisk together the 1 cup of all-purpose flour, 1/2 cup of packed light brown sugar, cinnamon, and nutmeg. The brown sugar adds a lovely caramel flavor, and the spices complement the fruit perfectly.
- Cut in the Butter: Add the cold, cubed butter to the dry ingredients. Using a pastry blender or your fingertips, cut the butter into the flour mixture until it resembles coarse crumbs. The key here is to keep the butter cold, as this will create a tender and crumbly topping. If you don't have a pastry blender, you can use two knives to cut the butter in.
- Chill (Optional but Recommended): If you have time, cover the bowl and chill the crumble topping in the refrigerator for about 15-20 minutes. This will help the butter stay firm and prevent the topping from spreading too much during baking.
Preparing the Cake Batter:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan. I find that using baking spray with flour works really well to prevent sticking.
- Combine Dry Ingredients: In a medium bowl, whisk together the 2 1/2 cups of all-purpose flour, baking powder, baking soda, and salt. Whisking ensures that the leavening agents are evenly distributed throughout the flour.
- Cream Butter and Sugar: In a large bowl (or the bowl of a stand mixer), cream together the softened butter and 1 3/4 cups of granulated sugar until light and fluffy. This usually takes about 3-5 minutes. Creaming the butter and sugar incorporates air into the batter, which helps create a tender cake.
- Add Eggs: Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. Then, stir in the vanilla extract.
- Alternate Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Begin and end with the dry ingredients. So, add about 1/3 of the dry ingredients, then 1/2 of the buttermilk, then another 1/3 of the dry ingredients, then the remaining buttermilk, and finally the remaining dry ingredients. Mix until just combined. Be careful not to overmix, as this can result in a tough cake.
Assembling and Baking the Cake:
- Pour Batter into Pan: Pour the cake batter into the prepared 9x13 inch baking pan and spread it evenly.
- Top with Filling: Spoon the strawberry rhubarb filling evenly over the cake batter. Don't worry if some of the juices seep into the batter; this will add moisture and flavor.
- Sprinkle with Crumble: Sprinkle the crumble topping evenly over the fruit filling. Make sure to cover the entire surface for a beautiful and delicious crust.
- Bake: Bake in the preheated oven for 45-55 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. The top should be golden brown, and the filling should be bubbly.
- Cool: Let the cake cool in the pan for at least 30 minutes before slicing and serving. This allows the filling to set slightly and prevents the cake from falling apart.
Optional Glaze:
- Whisk Together: In a small bowl, whisk together the powdered sugar and milk (or lemon juice) until smooth. Add more milk or lemon juice if needed to reach your desired consistency. I prefer a slightly thicker glaze, but you can make it thinner if you like.
- Drizzle: Once the cake has cooled slightly, drizzle the glaze over the top.
Tips for Success:
- Use Fresh Ingredients: Fresh rhubarb and strawberries will give you the best flavor.
- Don't Overmix: Overmixing the cake batter can result in a tough cake. Mix until just combined.
- Adjust Baking Time: Baking times may vary depending on your oven. Check the cake for doneness after 45 minutes.
- Let it Cool: Allowing the cake to cool before slicing is crucial for preventing it from falling apart.
- Storage: Store leftover cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
Variations:
- Add Nuts: Add chopped walnuts or pecans to the crumble topping for extra crunch and flavor.
- Use Different Fruits: Experiment with other fruits, such as blueberries, raspberries, or peaches.
- Spice it Up: Add a pinch of ground ginger or cardamom to the cake batter for a warm and spicy flavor.
- Make it Gluten-Free: Use a gluten-free all-purpose flour blend to make this cake gluten-free.
