Strawberry Rhubarb Crumb Bars – Easy & Buttery Summer Treat

I’ll be honest with you—I didn’t plan to fall in love with strawberry rhubarb crumb bars. It just happened one summer when I had fresh rhubarb from a neighbor and a box of sweet strawberries sitting in my kitchen.

I didn’t want to make a pie because pies take too much time. So I thought, “Why not crumb bars?” That’s how this recipe came alive.

You’ll like these because they’re simple, buttery, and taste like summer in every bite. No fancy tools, no long hours in the kitchen. Just pure, cozy sweetness.


What Makes These Bars Special

These bars are not just any dessert. They have three layers that make them perfect:

  1. The base – buttery and soft but strong enough to hold the filling.
  2. The filling – fresh strawberries mixed with tart rhubarb, sweet and tangy at the same time.
  3. The crumb topping – golden, buttery, and slightly crunchy.

It’s that mix of soft, sweet, tart, and crumbly that makes these bars unforgettable.


Ingredients You’ll Need

Don’t worry, nothing here is complicated. Most of this you probably already have in your kitchen:

  • Fresh strawberries
  • Fresh rhubarb
  • Sugar (to balance the tartness)
  • All-purpose flour
  • Butter (the hero of this recipe)
  • Baking powder
  • Salt
  • Vanilla extract

That’s it. Simple, real ingredients.


Step 1: Make the Base

The base is like a shortbread cookie. You mix butter, flour, sugar, a little baking powder, and salt. Press it into your baking pan. This layer gives your bars a solid foundation.


Step 2: Mix the Filling

Cut strawberries and rhubarb into small pieces. Toss them with sugar so they release some juice. This is where the sweet and tangy flavor comes alive.

When baked, the filling turns jammy and delicious.


Step 3: Add the Crumb Topping

Take some of the dough you used for the base, crumble it with your hands, and sprinkle it over the fruit. When it bakes, this topping turns golden and crunchy.

Every bite will have that buttery crumb mixed with sweet fruit.


Step 4: Bake Until Golden

Pop the pan into the oven and let the magic happen. You’ll know it’s ready when your kitchen smells like butter and fruit pie. The topping should be golden brown and the fruit bubbling.


How to Serve Them

Here’s the best part—you can eat them warm or cold. I like them slightly warm with a scoop of vanilla ice cream. But they’re also amazing chilled, almost like a fruity cookie bar.


Why You’ll Love These Bars Too

  • They’re easy – no rolling, no pie crust stress.
