Strawberry Rhubarb Cake (Easy, Tender, and Bursting with Flavor)
This easy Strawberry Rhubarb Cake is soft, buttery, and loaded with juicy fruit in every bite. A simple, crowd-pleasing dessert that works for summer gatherings, brunches, or cozy weeknight treats.
The Strawberry Rhubarb Cake You Will Make Every Summer
If you have never baked with rhubarb before, this is the recipe that will make you a convert. This Easy Strawberry Rhubarb Cake is the kind of dessert that disappears from the pan within hours. The crumb is soft and buttery, the fruit stays jammy and bright, and that cinnamon sugar crust on top gives every slice a gentle, caramelized crunch. It is simple enough for a weeknight and beautiful enough for a summer gathering.
What makes this Strawberry Rhubarb Cake Recipe stand out is the balance. Rhubarb is famously tart, almost shockingly so on its own. But nestled into a sweet, vanilla-scented batter alongside ripe strawberries, it transforms into something complex and addictive. Think of it as the lovechild of a classic coffee cake and a fruit cobbler, but far more elegant than either.
Using a good hand mixer or stand mixer makes a real difference when creaming butter and sugar, and a sturdy square baking pan ensures even heat distribution so your cake bakes up level and golden all the way through. Here are the tools and ingredients that genuinely help this recipe come out perfectly:
Why This Recipe Works So Well
The secret behind this cake is sour cream. It adds fat and acidity in equal measure, which means a crumb that stays moist for days and a subtle tang that perfectly complements the rhubarb. Many Strawberry Rhubarb Cake recipes skip this step, and you can always taste the difference.
The other key move is tossing your fruit with a tablespoon of cornstarch before it goes into the batter. Rhubarb releases a surprising amount of liquid as it bakes, and without that buffer, you risk a gummy, undercooked center. The cornstarch absorbs the excess and keeps everything set up cleanly.
Chef's Tip: Do not skip the parchment paper lining. Strawberry and rhubarb juice can stick aggressively to the pan, and parchment means your slices come out clean and picture-perfect every time.
Fresh vs. Frozen Fruit: What to Use
Fresh rhubarb is ideal when it is in season, typically from late spring through early summer. Look for firm, deeply colored stalks without any soft spots. For the strawberries, go for the ripest ones you can find. Pale, out-of-season berries will not give you that deep, jammy flavor.
That said, this is a forgiving recipe. Frozen strawberries and frozen rhubarb both work beautifully here, making this a viable Strawberry Easy Dessert Recipe year-round. Just remember to thaw and dry your frozen fruit thoroughly before using it.
Thinking about a faster version? You can absolutely adapt this into a Strawberry Rhubarb Dump Cake With Cake Mix by layering fruit filling and dry cake mix in a pan and finishing it with melted butter. It will not have the same tender crumb, but it is a wonderful shortcut when time is short.
Serving Ideas
This cake is genuinely wonderful on its own, but a few simple additions take it over the top:
- Warm with vanilla ice cream for a classic summer dessert
- With a dollop of whipped cream and a few fresh strawberry slices
- At room temperature for breakfast alongside your morning coffee, because yes, it absolutely counts as a Strawberry Rhubarb Breakfast Cake
- Dusted with powdered sugar for a clean, elegant presentation at a brunch table

Strawberry Rhubarb Cake (Easy, Tender, and Bursting with Flavor)
This easy Strawberry Rhubarb Cake is soft, buttery, and loaded with juicy fruit in every bite. A simple, crowd-pleasing dessert that works for summer gatherings, brunches, or cozy weeknight treats.
Ingredients
- 1 1/2 cups all-purpose flour, spooned and leveled
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/4 tsp salt
- 3/4 cups granulated sugar, plus 2 tbsp for topping
- 1/2 cups unsalted butter, softened to room temperature
- 2 large eggs, room temperature
- 1 tsp vanilla extract, pure, not imitation
- 1/2 cups sour cream, full-fat, room temperature
- 1 cups fresh strawberries, hulled and sliced into quarters
- 1 cups fresh rhubarb, trimmed and cut into 0.5-inch pieces
- 1 tbsp cornstarch, tossed with the fruit to reduce excess moisture
- 1/2 tsp cinnamon, for topping
Instruction
Preheat your oven to 350 degrees F (175 degrees C). Grease an 8x8-inch or 9x9-inch square baking pan and line it with parchment paper, leaving an overhang on two sides for easy removal.
In a medium bowl, toss the sliced strawberries and rhubarb pieces with the cornstarch until evenly coated. Set aside.
In a large bowl, beat the softened butter and 3/4 cup granulated sugar together with a hand mixer or stand mixer on medium-high speed for about 3 minutes, until light and fluffy.
Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
With the mixer on low, add half of the flour mixture to the butter mixture and mix until just combined. Add the sour cream and mix briefly. Add the remaining flour mixture and stir until a thick, smooth batter forms. Do not overmix.
Spread the batter evenly into the prepared pan. Scatter the strawberry and rhubarb mixture over the top, pressing the pieces gently into the batter.
In a small bowl, mix the remaining 2 tablespoons of sugar with the cinnamon. Sprinkle evenly over the fruit.
Bake for 45 to 55 minutes, until the top is golden, the edges pull away from the pan, and a toothpick inserted into the center comes out with just a few moist crumbs.
Allow the cake to cool in the pan for at least 20 minutes before lifting it out using the parchment overhang. Slice and serve warm or at room temperature.
Equipment
- 8x8 or 9x9-inch square baking pan

- Large mixing bowl

- Toothpick or cake tester
Notes
Storing and Making Ahead
This cake holds up beautifully. Stored covered at room temperature, it stays moist for 2 days. In the refrigerator, it keeps for up to 5 days, and the flavors actually deepen overnight as the fruit settles into the crumb. For longer storage, wrap individual slices tightly and freeze for up to 2 months. Reheat from frozen in a 300 degree F oven for about 10 minutes or microwave individual slices for 30 seconds.
If you are planning ahead for a party or brunch, bake the cake the night before and store it covered on the counter. It slices more cleanly once fully cooled, which makes serving a crowd effortless.
