Ingredients

For the Crust and Crumble:

• 2½ cups (310g) all-purpose flour
• 1 cup (200g) granulated sugar
• ½ teaspoon salt
• 1 cup (226g) unsalted butter, cold and cubed
• 1 large egg
• ½ teaspoon vanilla extract

For the Cranberry Filling:

• 4 cups (400g) fresh or frozen cranberries
• ¾ cup (150g) granulated sugar
• 1 tablespoon orange zest (from 1 medium orange)
• ¼ cup (60ml) fresh orange juice
• 2 tablespoons cornstarch
• ½ teaspoon ground cinnamon
• ¼ teaspoon ground ginger

The star of these Cranberry Crumble Bars is undoubtedly the cranberries themselves—tart, bright, and bursting with flavor. Fresh cranberries provide the best texture and flavor, but frozen work beautifully when fresh aren’t in season. The orange zest and juice complement the cranberries perfectly, bringing citrus notes that enhance rather than overwhelm the berry flavor.

Pro Tips

Perfect Your Crumble Texture
For truly exceptional Cranberry Crumble Bars, the texture of your crumble is crucial. Use very cold butter and cut it into the flour mixture until it resembles coarse crumbs—not fine sand. Overworking will create a tough rather than tender crumble. For the best texture, after mixing in the egg, gently squeeze the mixture in your hand—it should just hold together when pressed but still feel somewhat loose. This ensures your bars will have that perfect crumbly texture that melts in your mouth.

Master the Filling Consistency
The cranberry filling needs to strike the perfect balance between jammy and sliceable. Cooking the cranberries until most have burst (but not all) gives your bars texture while ensuring they’ll hold together when cut. The cornstarch is non-negotiable—it thickens the filling so it sets properly without making your bars soggy. Let the filling cool completely before assembling for clean, defined layers.

Achieve Clean-Cut Bars
For picture-perfect Cranberry Crumble Bars, patience is key. After baking, allow the bars to cool completely in the pan, then refrigerate for at least two hours (or ideally overnight) before cutting. Use a sharp knife wiped clean between cuts, and for the cleanest edges, dip your knife in hot water and dry it between slices. This extra attention to detail makes the difference between rustic bars and professional-looking treats.

Instructions

Prepare the Pan and Oven
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the sides to easily lift the bars out later. This parchment sling is crucial for removing the Cranberry Crumble Bars intact.

Make the Crust and Crumble Mixture
In a large bowl, whisk together the flour, sugar, and salt. Add the cold cubed butter and use a pastry cutter or your fingertips to work it into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining. Whisk the egg and vanilla together in a small bowl, then pour into the flour mixture. Mix until the dough starts to come together when squeezed.

Form the Base Layer
Press two-thirds of the dough firmly and evenly into the bottom of your prepared pan. Make sure it’s packed down well to create a solid foundation for your Cranberry Crumble Bars. Place the pan in the refrigerator while you prepare the filling. Reserve the remaining dough for the topping.

Cook the Cranberry Filling
In a medium saucepan, combine cranberries, sugar, orange zest, and juice. Cook over medium heat, stirring occasionally, until the cranberries begin to burst, about 5-7 minutes. In a small bowl, mix cornstarch with 2 tablespoons of water to create a slurry. Pour into the cranberry mixture, add cinnamon and ginger, then stir constantly for 1-2 minutes until thickened. Remove from heat and let cool slightly.

Assemble and Bake
Spread the cranberry filling evenly over the chilled crust. Crumble the remaining dough over the top, allowing some cranberry filling to peek through. Bake for 40-45 minutes until the crumble is golden brown and the filling is bubbling around the edges. The contrast between the ruby filling and golden crumble creates the signature look of Cranberry Crumble Bars.

Cool and Slice
Allow the bars to cool completely in the pan on a wire rack, then refrigerate for at least 2 hours before cutting into squares. These bars actually improve with a little time as the flavors meld together.

Variations

Mixed Berry Crumble Bars
Give your Cranberry Crumble Bars a twist by replacing half the cranberries with blueberries, raspberries, or blackberries. This variation creates a less tart filling while maintaining the beautiful jewel-toned color. Adjust the sugar slightly depending on the sweetness of your berries. The mixed berries pair beautifully with the buttery crumble while offering a different flavor profile that works year-round.

Spiced Cranberry Orange Bars
Enhance the holiday appeal of these cranberry bars by doubling the cinnamon and adding ¼ teaspoon each of nutmeg and allspice to the filling. Increase the orange zest to 2 tablespoons for more pronounced citrus notes. This variation transforms your Cranberry Crumble Bars into a festive treat that tastes like the holidays in bar form. The warming spices complement the tart cranberries perfectly for a cozy, comforting dessert.

Gluten-Free Adaptation
Create gluten-free Cranberry Crumble Bars by substituting the all-purpose flour with a high-quality cup-for-cup gluten-free flour blend. Add ¼ teaspoon of xanthan gum if your blend doesn’t include it. The buttery, crumbly texture remains delicious, making these bars perfect for mixed dietary needs during holiday gatherings or family events.

Storage and Serving

These Cranberry Crumble Bars store beautifully, making them perfect for advance preparation. Keep them in an airtight container in the refrigerator for up to 5 days. The flavors actually develop and improve after a day, making them an ideal make-ahead dessert. For longer storage, freeze cut bars individually wrapped in plastic, then stored in a freezer bag for up to 3 months. Thaw overnight in the refrigerator before serving.

Serve these versatile bars in multiple ways to suit any occasion. For an elegant dessert, warm them slightly and serve with a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream. The contrast between the warm bar and cold topping is heavenly. For brunch, they’re perfect as is alongside coffee or tea. You can even transform them into a decadent breakfast by warming and topping with a spoonful of Greek yogurt and a drizzle of honey.

FAQs

Can I use dried cranberries instead of fresh?
Fresh or frozen cranberries are strongly recommended for Cranberry Crumble Bars as they create the jammy texture. If using dried, you’ll need to rehydrate them first by simmering 2 cups of dried cranberries with 1½ cups of water and ¼ cup orange juice for 15-20 minutes until plump before proceeding with the recipe.

Why did my filling leak through the crust?
This typically happens if the bottom crust isn’t packed firmly enough. Make sure to press the dough into a compact, even layer, then refrigerate it while preparing the filling to help it set. Also, ensure your filling has thickened properly with cornstarch before adding it to the crust.

Can I make these bars ahead of time for a party?
Absolutely! Cranberry Crumble Bars actually improve with time as the flavors meld. Make them 1-2 days before your event and store in the refrigerator for best results.

My crumble topping seemed too wet or too dry. What happened?
The perfect crumble should just hold together when squeezed but still be somewhat loose. If it’s too wet, add a tablespoon of flour at a time until it reaches the right consistency. If too dry, add a teaspoon of cold water or a small amount of beaten egg.

Are these bars freezer-friendly?
Yes! Cranberry Crumble Bars freeze beautifully for up to 3 months. Cut into squares, wrap individually, and store in a freezer bag. Thaw in the refrigerator overnight before serving.

These Cranberry Crumble Bars are comfort food at its finest — ruby-red, tangy-sweet treasures nestled between layers of buttery, golden crumble that provide the perfect textural contrast in every bite.
