This strawberry rhubarb cobbler combines the tangy kick of spring rhubarb with sweet strawberries under a buttery, golden crust. The contrast between the jammy fruit filling and crisp topping creates a dessert that perfectly balances sweet and tart flavors for a classic seasonal treat that never disappoints.
I first made this cobbler when my local farmers market had both strawberries and rhubarb in peak season. The kitchen filled with the most amazing aroma as it baked, and now it's our unofficial welcome to spring dessert every year.
Ingredients
- Fresh rhubarb: Adds a bright tanginess that gives this dessert its signature flavor. Look for firm stalks with vibrant color.
- Fresh strawberries: Provide natural sweetness that balances the tartness of rhubarb. Choose ripe, fragrant berries for best flavor.
- Cornstarch or tapioca: Thickens the fruit juices into a luscious sauce. Either works well, though tapioca gives a slightly clearer finish.
- Cold butter: Creates those perfect flaky pockets in the topping. Keep it in the refrigerator until the last minute.
- Boiling water: Helps create a uniquely textured topping that's part biscuit, part cake. Don't substitute room temperature water.
- Vanilla extract: Adds depth to the topping. Use pure vanilla for the best flavor profile.
Step-by-Step Instructions
- Prepare the Fruit Filling:
- Combine the chopped rhubarb and strawberries in a large bowl with sugar and cornstarch or tapioca. The sugar draws out the juices while the thickener will prevent the filling from becoming too watery. If using tapioca, allow the mixture to rest for 15 minutes so the tapioca can begin absorbing the fruit juices.
- Transfer to Baking Dish:
- Pour the fruit mixture including all accumulated juices into a 9×13-inch baking dish, spreading it evenly. This size dish provides the perfect ratio of fruit filling to topping.
- Make the Cobbler Topping:
- In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined. Add the cold cubed butter and use a pastry cutter to work it into the dry ingredients until the mixture resembles coarse crumbs about the size of peas. The cold butter creates pockets of steam during baking which results in a tender, flaky topping.
- Add Wet Ingredients:
- Pour the boiling hot water and vanilla extract into the flour mixture and stir just until the dough starts to come together. It should look somewhat shaggy with some dry bits remaining. Overmixing will create a tough topping.
- Assemble and Bake:
- Spoon or crumble the topping mixture evenly over the fruit filling. Don't worry about covering every spot perfectly. The gaps allow the beautiful fruit filling to bubble up around the edges. Sprinkle additional sugar on top if desired for extra crunch and sweetness. Bake in the preheated oven until the topping is golden brown and the filling is actively bubbling around the edges.

My absolute favorite part of this recipe is the moment when the topping and filling meet during baking. The bottom of the topping soaks up some of the fruit juices while still maintaining a crisp top, creating the most incredible texture contrast. My grandmother used to make a similar cobbler, and that first bite always takes me right back to her kitchen.
Choosing the Perfect Rhubarb
Rhubarb is the star of this dessert, so selecting good quality stalks matters. Look for firm, crisp stalks with shiny skin and vibrant color ranging from pale pink to deep red. While color doesn't necessarily indicate ripeness, deeper red varieties often have a sweeter flavor profile. Avoid any stalks that appear wilted, stringy or have soft spots. Remember that rhubarb leaves are toxic and should always be removed before cooking. If using garden rhubarb, harvest stalks that are at least 10 inches long for the best flavor and texture.
Making Ahead and Storage
This cobbler can be assembled up to a day in advance before baking. Prepare the filling and place it in the baking dish, then cover tightly and refrigerate. Make the topping separately and store in an airtight container in the refrigerator. When ready to bake, sprinkle the cold topping over the filling and add a few minutes to the baking time. Leftover cobbler can be stored covered at room temperature for up to 2 days or refrigerated for up to 5 days. Reheat individual portions in the microwave for 30 seconds or place the whole dish in a 300°F oven until warmed through.

Seasonal Variations
While strawberry and rhubarb are a classic springtime pairing, this versatile cobbler recipe works beautifully with other fruit combinations throughout the year. In summer, try peaches and blackberries or blueberries and nectarines. Fall brings opportunities for apple and cranberry or pear and ginger combinations. Winter citrus like blood oranges paired with cranberries make a vibrant off season version. Adjust the sugar levels depending on the natural sweetness of your chosen fruits. The topping recipe remains the same regardless of which fruits you choose, making this a wonderful year round dessert template.
Frequently Asked Questions
- → Can I use frozen fruit for this cobbler?
Yes, you can use frozen rhubarb and strawberries. There's no need to thaw them first, but you may need to increase the baking time by 5-10 minutes to account for the frozen fruit. You might also want to add an extra tablespoon of cornstarch to account for the extra moisture.
- → What's the difference between a cobbler and a crisp?
A cobbler traditionally has a biscuit-like topping that's dropped or spooned over fruit filling, creating a cobbled appearance when baked. A crisp has a streusel topping made with oats, flour, butter, and sugar that becomes crisp during baking. This particular cobbler has elements of both styles with its buttery crumble topping.
- → How do I know when rhubarb is ripe and ready to use?
Rhubarb is ready to harvest when the stalks are at least 10 inches long. The color isn't necessarily an indicator of ripeness - some varieties remain green when ripe while others turn red. Look for firm, crisp stalks. Avoid any that are limp or have blemishes.
- → Can I make this cobbler ahead of time?
Yes, you can prepare the cobbler up to a day in advance. Either assemble completely and refrigerate unbaked (adding an extra 10 minutes to baking time), or bake it completely, cool, and refrigerate. Reheat in a 300°F oven for about 20 minutes before serving for the best texture and flavor.
- → How should I store leftover cobbler?
Cover leftovers with plastic wrap or transfer to an airtight container and store in the refrigerator for up to 4 days. The topping will soften over time but will still be delicious. You can reheat individual portions in the microwave for 30-45 seconds or warm in a 300°F oven for about 15 minutes.
- → Can I reduce the sugar in this cobbler?
Yes, you can reduce the sugar in both the filling and topping if you prefer a less sweet dessert. For the filling, you could go down to 1/2 cup of sugar, especially if your strawberries are particularly sweet. For the topping, you could reduce to 3/4 cup of sugar without significantly affecting the texture.
