Ingredients You’ll Need

This Cranberry Crumble Bars Recipe calls for simple yet essential ingredients that work together beautifully to create its signature taste and texture. Each component plays an important role—from the rich butter in the shortbread to the zesty orange in the cranberry filling, ensuring your bars are bursting with flavor and just the right amount of crumble.

Unsalted butter (1 cup, room temperature): The foundation of the shortbread crust that lends a rich, flaky texture.
Granulated sugar (1/2 cup): Adds sweetness and helps achieve that tender crumb in the crust.
Light brown sugar (1/2 cup, packed): Contributes moisture and a lovely caramel hint to the dough.
Large egg (1, room temperature): Binds the dough and adds richness.
Vanilla extract (2 teaspoons + 1 teaspoon): Enhances all the flavors with its warm, sweet aroma.
All-purpose flour (3 1/4 cups): The structure for your bars, it’s spooned and leveled for perfect measurement.
Baking powder (3/4 teaspoon): Lightly lifts the dough for a tender crumb.
Cinnamon (1 teaspoon): Adds a gentle warmth that complements the tart cranberries.
Kosher salt (1/4 teaspoon): Balances sweetness and highlights flavors.
Fresh or frozen cranberries (2 1/2 cups): The star of the show, bursting with tartness and juiciness.
Granulated sugar (2/3 cup): Sweetens the cranberry filling without overpowering it.
Cornstarch (1 tablespoon): Helps thicken the cranberry filling into a luscious layer.
Orange zest (1 tablespoon): Introduces a bright citrus note that pairs perfectly with cranberries.
Orange juice (1 tablespoon): Adds tang and moisture to the filling.
Powdered sugar (3/4 cup, sifted): For making the smooth vanilla glaze topping.
Whole milk or heavy cream (4 tablespoons): Combines with powdered sugar for the perfect glaze consistency.

How to Make Cranberry Crumble Bars Recipe

Step 1: Prepare the Shortbread Dough

Begin by creaming together the unsalted butter and both sugars until your mixture grows light and fluffy, about three minutes. This step is crucial because it incorporates air, giving your crust a tender, melt-in-your-mouth texture. Then, mix in the egg and vanilla for richness and a beautiful aroma. Scrape the bowl to make sure every bit of goodness is mixed evenly.

Step 2: Combine the Dry Ingredients

In a separate bowl, whisk the flour, baking powder, cinnamon, and kosher salt. These dry ingredients will work together to provide the structure and subtle spice depth to your crust. Avoid over-mixing later to keep your crumble tender.

Step 3: Form the Dough and Reserve

Gradually add the dry ingredients to the wet mixture just until the dough begins to pull away from the bowl’s sides. Overworking it can make the crust tough, so gentle is key here. Take about 2 cups of this dough and set it aside loosely packed; it will become the crumble topping.

Step 4: Press and Prebake the Crust

Press the remaining dough firmly and evenly into an 8×8-inch pan lined with parchment paper. Use your hands or the flat base of a measuring cup to get into all corners. Bake at 350°F for 15 minutes, watching carefully for those edges to turn a light golden brown while the center barely sets. This pre-baking prevents a soggy bottom once you add the vibrant filling.

Step 5: Make the Cranberry Filling

While your crust cools, whisk cranberries with sugar, cornstarch, orange zest, orange juice, and vanilla. This mix combines tartness with sweetness and a citrus zing, giving your bars that irresistible tangy punch. Pour this vibrant mixture evenly over your slightly cooled shortbread crust.

Step 6: Add the Crumble Topping and Bake

Break the reserved dough into smaller, flat pieces using your hands and scatter these pieces across the cranberry filling, leaving gaps to allow the filling to peek through. Bake for about 45 minutes, then cover the top loosely with foil for the last 10 to 15 minutes to prevent over-browning while ensuring the filling bubbles and sets perfectly.

Step 7: Cool and Glaze

Once baked, set the pan on a wire rack and allow the bars to cool completely—this step helps the filling thicken to the ideal sliceable consistency. Lastly, whisk together powdered sugar, milk or cream, and vanilla to make a delicate glaze, drizzling it atop your bars for a sweet finishing touch.

Side Dishes

For an extra decadent experience, serve these bars alongside a scoop of vanilla ice cream or a dollop of whipped cream which complements the tartness beautifully. A cup of warm spiced tea or coffee is also a perfect beverage companion, highlighting the cinnamon and citrus notes.

Make Ahead and Storage

Storing Leftovers

Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week to keep freshness. The crumbly texture holds up well, and the flavors actually deepen over time.

Freezing

Wrap bars tightly in plastic wrap and aluminum foil before freezing to avoid freezer burn. They can last up to 3 months frozen and make an excellent make-ahead treat for busy days or holiday feasts.

Reheating

To enjoy a warm version, thaw frozen bars overnight in the fridge and reheat gently in a low oven (around 300°F) for 10-15 minutes. This refreshes the crumbly crust and makes the cranberry filling luscious again without drying out the bars.

FAQs

Can I use frozen cranberries instead of fresh?

Absolutely! Frozen cranberries work wonderfully and bring the same lovely tartness. Just thaw and drain any excess liquid before mixing with the sugar and other filling ingredients to avoid a watery filling.

How do I prevent the crumble topping from burning?

Covering the bars loosely with foil during the last 10 to 15 minutes of baking is key to preventing the topping from becoming too dark while allowing the filling to finish cooking.

Can I make this recipe gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free blend designed for baking. Just ensure it includes xanthan gum or another binder to keep your crust tender and crumbly.

Is it necessary to pre-bake the crust?

Pre-baking the crust ensures it is cooked through and prevents sogginess from the moist cranberry filling. Skipping this step could result in a doughy or undercooked base.

How long do the bars stay fresh?

When stored properly in an airtight container, these bars remain fresh for about 3 days at room temperature and up to a week refrigerated. Their flavors and textures mellow and develop even more over time.
