Ingredients You’ll Need

All the ingredients in Nana’s Strawberry Rhubarb Cake Recipe are simple pantry staples and fresh produce, but don’t let their simplicity fool you. Each item plays a crucial role—flour and leavening agents create a soft, airy crumb, while strawberries and rhubarb bring vibrant color and that signature balance of sweet and tart.

• 2 cups all-purpose flour: The base of the cake providing structure and a soft crumb.
• 1 tsp baking powder: Helps the cake rise just enough for lightness without airiness.
• ½ tsp baking soda: Adds lift and ensures the right texture when combined with the acidic buttermilk.
• ½ tsp salt: Enhances all the flavors, including the sweetness and fruitiness.
• 1 cup unsalted butter, softened: Offers richness and tenderizes the crumb for that melt-in-your-mouth feel.
• 1 cup granulated sugar: Sweetens the cake perfectly without overpowering.
• 2 large eggs: Bind ingredients and add moisture and structure.
• 1 tsp vanilla extract: Infuses the cake with a warm, aromatic essence.
• 1 cup buttermilk (or milk + lemon juice): Adds tang and moisture while reacting with the baking soda for lift.
• 2 cups fresh strawberries, hulled and sliced: Provide natural sweetness and a gorgeous red hue.
• 2 cups rhubarb, chopped: Brings a subtle tartness that beautifully contrasts the strawberries.
• ½ cup granulated sugar: Sweetens the fruit filling to balance the rhubarb’s sharpness.
• 1 tbsp cornstarch (optional): Thickens the fruit topping to prevent it from becoming watery.
• 1/3 cup granulated sugar: Used in the streusel for a pleasant crunch.
• 1/3 cup all-purpose flour: Forms the base of the streusel topping.
• 3 tbsp unsalted butter, cold and cut into small pieces: Creates the crumbly texture of the streusel layer.

How to Make Nana’s Strawberry Rhubarb Cake Recipe

Step 1: Get Ready by Preheating and Greasing

Start by preheating your oven to 350°F (175°C). This ensures it’s nice and hot the moment the cake goes in. Don’t forget to grease a 9×13-inch baking pan thoroughly—this little step means your cake will come out beautifully without sticking.

Step 2: Mix the Dry Ingredients

Whisk together the flour, baking powder, baking soda, and salt in a medium bowl. This step ensures your leavening agents and salt are evenly distributed so your cake rises and flavors evenly everywhere.

Step 3: Cream the Butter and Sugar

In a large bowl, beat the softened butter and 1 cup of granulated sugar until the mixture becomes creamy and fluffy. This is the secret to a light cake texture. Then, incorporate the eggs one at a time, beating well after each, and stir in the warm notes of vanilla extract.

Step 4: Combine Wet and Dry Ingredients Alternately

Add the dry ingredients into the buttery mix in stages, alternating with the buttermilk. Begin and end with the dry components, gently folding them in until just combined. Overmixing here can toughen the cake, so a light hand wins the day.

Step 5: Spread the Batter and Prepare the Fruit Topping

Pour your cake batter evenly into the greased pan. Then, in a separate bowl, gently mix the sliced strawberries, chopped rhubarb, ½ cup sugar, and optional cornstarch. This fruit mixture will give your cake its luscious burst of flavor.

Step 6: Add the Fruit on Top of the Batter

Carefully spread the strawberry-rhubarb mixture over the batter, making sure it’s distributed evenly so every slice has the perfect amount of fruit.

Step 7: Create and Sprinkle the Streusel Topping

For that irresistible crumbly layer, combine sugar, flour, and cold butter in a small bowl. Use your fingertips or a pastry cutter to work the butter into the dry mix until crumbly. Sprinkle this generously over the fruit to add enticing texture and a little extra sweetness.

Step 8: Bake Your Cake to Perfection

Place the baking pan in the preheated oven and bake for 45 to 50 minutes. The cake is ready when a toothpick inserted into the center emerges clean, signaling a perfectly baked, moist interior.

Step 9: Cool and Get Ready to Enjoy

Allow the cake to rest in the pan for about 10 minutes to settle and make slicing easier. Serve it warm or at room temperature with a dollop of whipped cream or a scoop of vanilla ice cream for an extra special touch.

How to Serve Nana’s Strawberry Rhubarb Cake Recipe

Garnishes

Adding a handful of fresh mint leaves or a light dusting of powdered sugar changes the whole presentation and adds a fresh or sweet finish. Whipped cream or vanilla ice cream is a classic, but even a drizzle of honey can bring the flavors to life.

Side Dishes

This delightful cake pairs wonderfully with a simple cup of tea, a refreshing iced lemonade, or even a lightly brewed coffee. For brunch, serving alongside fresh fruit salad or a creamy yogurt parfait complements the cake’s tart-sweet complexity beautifully.

Creative Ways to Present

For a lovely twist, cut the cake into individual squares and place each on a small dessert plate topped with strawberry compote or an additional slice of fresh rhubarb for a dramatic flair. Serving it as a layered trifle with whipped cream and custard also turns Nana’s Strawberry Rhubarb Cake Recipe into a stunning showstopper.

Make Ahead and Storage

Storing Leftovers

Cover leftover cake tightly with plastic wrap or keep it in an airtight container. Stored at room temperature, it stays fresh for up to two days. For longer shelf life, refrigeration is best and will keep it moist and delicious for up to five days.

Freezing

You can freeze this cake to enjoy later. Wrap individual slices in plastic wrap and foil or place them in a freezer-safe container to prevent freezer burn. Frozen cake slices maintain their quality for up to three months and thaw beautifully overnight in the fridge.

Reheating

When you’re ready to eat, warm slices in the microwave for about 15 seconds or heat gently in a low oven until just warmed through. Reheating brings back that fresh-baked feeling and soft, buttery texture that defines Nana’s Strawberry Rhubarb Cake Recipe.

FAQs

Can I use frozen strawberries and rhubarb for this cake?

Yes, frozen berries can be used if fresh ones aren’t available. Make sure to thaw and drain excess liquid to avoid a soggy cake. Using cornstarch helps thicken the topping even more in this case.

What if I don’t have buttermilk?

You can easily make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk. Let it sit for 5 minutes before using it in the recipe, which echoes the acidity but still keeps the cake tender and moist.

Is there a way to make this cake gluten-free?

Absolutely! Swap the all-purpose flour for a gluten-free baking blend that can be used cup-for-cup, and double-check your baking powder to ensure it’s gluten-free. This adjustment keeps the cake just as delightful.

Can I omit the streusel topping?

Yes, the streusel topping is optional but adds a lovely crunch and sweetness. Without it, the cake will be simpler but still tasty and moist thanks to the fruity layer.

How long does this cake keep its best flavor?

For the freshest taste and texture, it’s best enjoyed within 2 to 3 days when stored properly. Beyond that, while still good, the fruit topping’s texture might soften and the cake can become denser.
