Strawberry Rhubarb Coffee Cake: A Taste of Nostalgia

There’s something undeniably comforting about the scent of a coffee cake baking in the oven. It instantly transports me back to my grandmother’s kitchen, where she’d effortlessly whip up the most incredible treats.

This Strawberry Rhubarb Coffee Cake, with its tangy-sweet filling and biscuit-like crust, captures that same essence of warmth and love. It’s a labor of love, yes, but every step is a little act of kitchen magic that culminates in a slice of pure, unadulterated joy.

Recipe Overview

• Prep Time: 45 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 45 minutes
• Servings: 15
• Yield: One 9×12 inch cake
• Dietary Type: Vegetarian

Ingredients

• 1 1⁄4 cups chilled unsalted butter, plus more softened unsalted butter, for pan
• 1⁄4 cup fresh lemon juice (about 2 lemons)
• 1⁄3 cup cornstarch
• 2 3⁄4 cups sugar
• 1 lb strawberries, hulled and sliced
• 1 1⁄2 lbs rhubarb, trimmed and cut into 1 inch pieces
• 3 3⁄4 cups all-purpose flour
• 1 teaspoon baking powder
• 1⁄2 teaspoon baking soda
• 1 pinch salt
• 2 large eggs
• 1 1⁄2 cups buttermilk
• 1 teaspoon pure vanilla extract

Equipment Needed

• 9x12x3 inch baking pan
• Medium saucepan
• Medium bowl
• Large bowl
• Whisk
• Pastry knife or two forks
• Small saucepan
• Wire rack

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Brush a 9x12x3 inch baking pan with softened butter and set it aside. This ensures the cake releases easily after baking.

2. Make the fruit sauce: In a medium saucepan, combine the lemon juice, cornstarch, and 1 cup of sugar. Add the strawberries and rhubarb. Cook over medium heat, stirring frequently, until the liquid has thickened, about 15 to 20 minutes. This creates a luscious, tart-sweet fruit compote. Transfer the sauce to a medium bowl and allow it to cool completely. Cooling the fruit filling will prevent it from melting into the cake batter.

3. Make the crumb topping: In a medium bowl, combine 3/4 cup of sugar and 3/4 cup of flour. Melt 1/4 cup of butter in a small saucepan over low heat. Drizzle the melted butter over the flour mixture. Using your hands, mix the mixture until it forms coarse crumbs. The key here is to use your fingertips to rub the butter into the flour, creating different sized crumbs for a more interesting texture. Set the crumb topping aside.

4. Make the cake batter: In a large bowl, whisk together the remaining 3 cups of flour, 1 cup of sugar, the baking powder, baking soda, and salt. Using a pastry knife or two forks, cut the chilled butter into the flour mixture until it resembles coarse meal. The butter should be cold so it doesn’t melt into the flour. This step creates the biscuit-like texture. In a separate bowl, mix together the eggs, buttermilk, and vanilla extract. Pour the wet ingredients into the flour mixture and stir until just combined. Be careful not to overmix, as this can result in a tough cake.

5. Assemble the cake: Spread half of the cake batter evenly into the prepared pan. Top with half of the cooled fruit sauce. Carefully spread the remaining batter over the fruit. If the batter is too thick to spread easily, drop spoonfuls of batter over the fruit and gently spread to cover. Top with the remaining fruit sauce, then sprinkle evenly with the crumb topping.

6. Bake: Bake in the preheated oven until the cake is golden brown and springs back when touched gently in the center, about 1 hour. If the crumb topping starts to brown too quickly, tent the cake loosely with aluminum foil during the last 15-20 minutes of baking. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean or with only a few moist crumbs, the cake is done.

7. Cool and Serve: Transfer the pan to a wire rack to cool slightly. Serve warm or at room temperature, cut into squares. This cake is best enjoyed soon after baking, but it can also be stored for later.

Expert Tips & Tricks

• Use Cold Butter: For the flakiest, most tender crust, make sure your butter is well chilled before cutting it into the flour mixture. You can even pop it in the freezer for 15 minutes beforehand.
• Don’t Overmix: Overmixing the cake batter will develop the gluten in the flour, resulting in a tough cake. Mix just until the ingredients are combined.
• Adjust Sweetness: Rhubarb can be quite tart, so feel free to adjust the amount of sugar in the fruit filling to your liking.
• Make Ahead: You can prepare the fruit sauce and crumb topping a day in advance and store them in the refrigerator. This will save you time on the day you plan to bake the cake.
• Revive Day-Old Cake: If your coffee cake has become slightly dry after a day or two, warm individual slices in the microwave for a few seconds to restore their moisture.

• Dairy-Free: Substitute the buttermilk with a mixture of non-dairy milk (such as almond or soy milk) and lemon juice or vinegar (1 tablespoon per cup of milk). Use a dairy-free butter substitute for the butter in the crust and crumb topping.
• Other Fruits: Feel free to experiment with other fruits in the filling, such as blueberries, raspberries, or peaches.
• Spice it Up: Add a pinch of cinnamon or nutmeg to the crumb topping for a warm, comforting flavor.
• Nuts: Mix chopped nuts, such as walnuts or pecans, into the crumb topping for added texture and flavor.

FAQs (Frequently Asked Questions)

Q: Can I use frozen rhubarb for this recipe?

A: Yes, you can use frozen rhubarb. Just be sure to thaw it completely and drain any excess liquid before adding it to the fruit filling.

Q: How do I prevent the crumb topping from sinking into the cake?

A: Make sure the cake batter is thick enough to support the crumb topping. If the batter is too thin, the topping may sink. You can also chill the crumb topping in the refrigerator for 15 minutes before sprinkling it over the cake.

Q: Can I make this cake in a different size pan?

A: Yes, you can make this cake in a 9×13 inch pan. You may need to adjust the baking time accordingly. Check for doneness after about 50 minutes.

Q: Why is my cake dry?

A: Overbaking is the most common cause of dry cake. Be sure to check for doneness frequently and remove the cake from the oven as soon as it is done. Also, avoid overmixing the batter, as this can also lead to a dry cake.

Q: Can I add a glaze to this coffee cake?

A: Absolutely! A simple powdered sugar glaze made with milk or lemon juice would be a delicious addition to this coffee cake. Simply whisk together powdered sugar and liquid until smooth, and drizzle over the cooled cake.
