Summer baking has always been my happy place, but let me tell you—these Strawberry Rhubarb Crumb Bars are something else. I came up with this recipe after wanting a dessert that wasn’t too heavy, something buttery, fruity, and quick to whip up when friends drop by. The first time I baked these, I couldn’t stop picking at the crumbly topping before it cooled (don’t judge—you’ll do the same!). What I love is how sweet strawberries and tart rhubarb balance each other out so beautifully. It’s fresh, summery, and addictive in the best way. And guess what? You don’t need fancy skills—just simple ingredients and a little love.
Now, let’s get into it.
Why Strawberry and Rhubarb Are the Perfect Match
Strawberries are sweet, soft, and juicy, while rhubarb is tart, crisp, and slightly tangy. On their own, rhubarb can be too sour, but when paired with strawberries, it turns into magic. This duo is often called the “power couple of summer desserts.” According to the USDA, rhubarb is rich in vitamin K and fiber, while strawberries bring in vitamin C and antioxidants—so you’re not just indulging, you’re sneaking in some goodness too.
The flavor contrast keeps every bite exciting. It’s not overly sweet, and it’s not puckeringly sour—it’s just right.
The Magic of the Crumb Topping
Let’s be real, the best part of any crumb bar is the topping. That golden, buttery layer that crumbles in your mouth and gives you just the right crunch. What makes it even better here is that the same dough works for both the base and the topping. You press part of it into the pan for a firm crust and sprinkle the rest on top to get that irresistible, bakery-style finish. Easy, right?
I like adding a pinch of cinnamon to the crumb because it deepens the flavor and makes your kitchen smell like pure heaven while these bake.
Ingredients You’ll Need
Here’s what you’ll need to make these Strawberry Rhubarb Crumb Bars. Nothing fancy—just pantry basics plus fresh fruit:
- 1 cup granulated sugar
- 3 cups all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup unsalted butter, chilled and cubed
- 1 egg
- 1 teaspoon vanilla extract
- 2 cups chopped fresh strawberries
- 2 cups chopped rhubarb
- 1/2 cup granulated sugar (for fruit)
- 2 tablespoons cornstarch
- 1 teaspoon cinnamon (optional)
That’s it. Simple ingredients come together for something that looks and tastes like it came from a bakery.
Step-by-Step Instructions
Step 1: Prepare the Fruit Filling
Wash and chop your strawberries and rhubarb. Toss them in a bowl with sugar and cornstarch. The sugar sweetens while the cornstarch thickens the juices so your bars don’t get soggy. Let this mixture sit while you prepare the crust—it gives the fruit time to release a little juice.
Step 2: Make the Dough
In a large bowl, mix the flour, sugar, baking powder, and salt. Cut in the butter with a fork or pastry cutter until the mixture looks crumbly, like coarse sand. Add the egg and vanilla extract, and mix until combined. This dough will feel crumbly but will hold together when pressed.
Step 3: Form the Base
Press about two-thirds of the dough into a greased 9×13-inch baking pan. Press it firmly to make a solid base.
Step 4: Add the Fruit Filling
Spread the strawberry-rhubarb mixture evenly over the crust. Make sure the fruit is distributed well so every bite gets both strawberry and rhubarb.
Step 5: Add the Crumb Topping
Sprinkle the remaining dough on top of the fruit. Don’t press it down—you want loose, crumbly pieces so the topping bakes golden and crisp.
Step 6: Bake and Cool
Bake at 375°F (190°C) for 40–45 minutes, or until the top is golden brown and the fruit is bubbling. Let it cool completely before cutting into bars (trust me, waiting is hard, but worth it).
Serving Ideas to Make Them Even Better
- Warm with Ice Cream: Vanilla ice cream on top of a warm bar = heaven.
- Cold from the Fridge: Perfect for hot summer days.
- With Whipped Cream: A dollop of fresh cream makes it extra light.
- Picnic Snack: These travel well—pack them up for a summer picnic.
Storage Tips
These bars last up to 3 days at room temperature in an airtight container. If you want them to stay longer, refrigerate for up to 5 days. They also freeze beautifully—just wrap tightly and thaw in the fridge before serving.

Tips for Success
- Chill your butter – Cold butter gives you that crumbly texture.
