These cherry crumb bars combine a buttery shortbread base, a sweet cherry filling, and a crunchy crumb topping. The shortbread dough doubles as both the base and the streusel, making the bars easy to prepare. The filling highlights fresh cherries, though sour cherries can be used if you prefer a tarter bite. 
Cherry season is short, so it’s the perfect time to bake something that truly celebrates ripe fruit. These cherry crumb bars travel well and are simpler to make than a full pie. A tender, buttery shortbread-like base supports a juicy cherry layer made with just a few ingredients so the cherries remain the star. A golden, crunchy crumb topping finishes each bar. I enjoy these cold from the refrigerator, but they’re equally delightful warm with coffee or topped with ice cream.
Making Cherry Crumb Bars
Below are clear steps and helpful tips to make these bars. If you prefer, skip to the recipe section further down.
For the cherry filling, combine 2 cups pitted, halved (or quartered) cherries with 1 tablespoon granulated sugar, 2 tablespoons cornstarch, and 1 tablespoon lemon juice. Toss gently until the fruit is evenly coated. The cornstarch thickens the filling while the lemon juice brightens the cherry flavor. Set the mixture aside. 
Tip: A cherry pitter speeds the prep significantly. Measure the cherries after pitting and slicing — some cherries can be halved and others quartered depending on size. I used slightly more than 1 lb (about 450 grams) of cherries for this recipe.
For the shortbread base and crumb topping, whisk together 1 3/4 cups all-purpose flour, 2/3 cup granulated sugar, 3 tablespoons cornstarch, and 1/4 teaspoon salt. Stir in 3/4 cup melted unsalted butter until the mixture becomes dry and crumbly — that texture is expected. 
Tip: When melting butter, do so carefully to avoid overheating. Melt until about three-quarters liquid, then whisk until smooth; residual warmth will finish melting any small remaining pieces.
Press a little more than half of the crumbly shortbread mixture firmly into the bottom of a lined 8×8-inch (20×20 cm) pan to form an even base. Bake this layer for about 15 minutes until it looks set. 
While the base bakes, stir 1 tablespoon brown sugar into the remaining shortbread mixture to enhance the topping’s color and crunch. 
Once the base has finished its first bake, spread the cherry filling evenly over it. If there’s a lot of liquid in your bowl, leave most of it behind so the base doesn’t become soggy. Crumble the reserved shortbread mixture over the cherries to form the topping; you can make the crumbs fine or larger depending on your preference. 
Bake the assembled bars for about 25 minutes more, until the top turns a light golden color and cherry juices bubble through in spots. Cooling completely — usually 3–4 hours — is essential before slicing so the filling can set and clean slices can be achieved. 
Using Sour Cherries
If you choose sour cherries, increase the sugar in the filling to 3 tablespoons to balance the tartness. The bars will still retain a pleasant tang that pairs nicely with the buttery shortbread base.
These cherry crumb bars deliver a satisfying contrast of tender shortbread and vibrant fruit. They’re an easier, portable alternative to a cherry pie and make a wonderful seasonal dessert. For more cherry-inspired baking ideas, consider options like black forest brownies, cherry almond pie bars, fresh cherry crisp, or cherry cobbler.

Summary: Buttery shortbread base, juicy cherry filling, and a crunchy crumb topping. Simple to assemble and perfect for cherry season.
Prep: 20 mins Cook: 45 mins Total: 1 hr 5 mins Servings: 9 large bars
Equipment
- 8×8 inch (20×20 cm) pan — note there is not quite enough batter for a 9×9 inch pan
Ingredients
Cherry Layer
- 2 cups pitted cherries (measure after pitting and slicing in half or quarters)
- 1 tablespoon granulated sugar (use 3 tablespoons if using sour cherries)
- 2 tablespoons cornstarch (16 grams)
- 1 tablespoon fresh lemon juice
Shortbread Base & Crumb Topping
- 3/4 cup unsalted butter (168 grams), melted
- 1 3/4 cups all-purpose flour (219 grams)
- 2/3 cup granulated sugar (133 grams)
- 3 tablespoons cornstarch (24 grams)
- 1/4 teaspoon salt
- 1 tablespoon brown sugar (for the crumb topping)
Instructions
- Preheat the oven to 325°F (170°C). Line an 8×8 inch pan with parchment paper, leaving an overhang for easy removal.
- Prepare the cherries: pit and slice each cherry in half or quarters as needed.
- In a medium bowl, toss the cherries with 1 tablespoon sugar, 2 tablespoons cornstarch, and 1 tablespoon lemon juice. Set aside.
- In a large bowl, whisk together 1 3/4 cups flour, 2/3 cup granulated sugar, 3 tablespoons cornstarch, and 1/4 teaspoon salt.
- Stir the melted butter into the dry ingredients until the mixture is crumbly.
- Press slightly more than half of the mixture into the prepared pan to form the shortbread base.
- Bake the base for 15–20 minutes, or until it looks set. Keep the oven on.
- Mix 1 tablespoon brown sugar into the remaining crumb mixture.
- Carefully spread the cherry filling over the baked base, leaving behind any excess juice from the mixing bowl.
- Crumble the remaining shortbread mixture over the cherries to form the topping.
- Return the pan to the oven and bake for about 25 minutes, until the top is golden and cherry juices bubble.
- Cool completely (about 3–4 hours) so the filling sets, then lift out using the parchment overhang and slice into bars.
Notes
- Cherries: Fresh cherries are recommended. Frozen cherries can extend bake time and may make the base soggy. The recipe uses slightly over 1 lb (450 g) fresh cherries.
- Nutrition: Nutritional information is an estimate per bar when the pan is divided into 9 equal pieces.
- Storage: Store in an airtight container in the refrigerator for up to 4 days.
