These easy-to-make Cranberry Crumble Bars come together with simple, wholesome ingredients that ensure every bite is bursting with flavor.
For the Crust
- Unsalted Butter – Provides richness and a tender texture; can be substituted with non-dairy alternatives.
- Granulated Sugar – Adds sweetness to both the crust and filling; no substitutions recommended.
- Light Brown Sugar – Contributes moisture and a hint of caramel flavor; can be replaced by all granulated sugar for a lighter taste.
- Egg – Binds the ingredients in the crust; for a vegan option, use a flax egg or other egg substitutes.
- Vanilla Extract – Enhances flavor beautifully; substitute with almond extract for a twist.
- All-Purpose Flour – The base for that delightful shortbread crust; for gluten-free options, use a gluten-free flour blend.
For the Filling
- Cranberries – Provides tartness and flavor contrast; fresh cranberries are recommended, but frozen can be used if thawed and drained.
- Granulated Sugar (for Filling) – Sweetens the cranberry filling; adjust according to taste preference.
- Cornstarch – Thickens the filling to hold everything together; arrowroot powder can be used as a substitute.
- Orange Zest and Juice – Adds a bright, citrusy flavor; lemon zest is a fine substitute if needed.
For the Glaze

Step‑by‑Step Instructions for Cranberry Crumble Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your oven is perfectly hot for baking those delightful Cranberry Crumble Bars. While the oven warms up, gather your ingredients, including the unsalted butter and sugars, so you’re ready to create that buttery shortbread crust.
Step 2: Make the Dough
In a stand mixer, combine softened unsalted butter, granulated sugar, and light brown sugar. Mix on medium speed until the mixture is light and fluffy, which should take about 3-4 minutes. This will create a rich base for your crust, so watch for a pale, airy consistency before moving on.
Step 3: Incorporate Wet Ingredients
Add in one large egg and a splash of vanilla extract to the butter and sugar mix. Continue mixing on low speed until all ingredients are well incorporated, approximately 1-2 minutes. This step is crucial, as it will bind the crust together while enhancing its flavor with that lovely vanilla aroma.
Step 4: Add the Flour
Gradually add all-purpose flour to the mixture, mixing just until the dough forms. Avoid overmixing to ensure your Cranberry Crumble Bars remain tender and crumbly. You’ll know you’ve reached the right consistency when the dough comes together cleanly and pulls away from the bowl.
Step 5: Prepare the Pan
Reserve 2 cups of the dough for the topping, then press the remaining dough evenly into an 8×8 inch baking pan lined with parchment paper. Make sure it’s packed firmly and evenly to create a sturdy base. The edges should be slightly higher than the center, forming a little wall for the filling.
Step 6: Bake the Crust
Place the pan in the oven and bake the crust for 15 minutes or until the edges turn a beautiful golden brown. Keep an eye on it, as this initial bake sets up the perfect foundation for your luscious cranberry filling and ensures a crispy bottom.
Step 7: Prepare the Filling
While the crust is baking, take a bowl and combine fresh or thawed cranberries, granulated sugar, cornstarch, orange zest, and orange juice. Stir this mixture gently until well combined. The goal is to coat the cranberries evenly, which creates a sweet-tart filling that bursts with flavor.
Step 8: Assemble the Bars
Once the crust reaches the golden stage, carefully spread the cranberry mixture evenly over the baked crust. Use a spatula to ensure the filling reaches the edges, allowing every bite of your Cranberry Crumble Bars to be packed with that delightful tartness.
Step 9: Crumble the Topping
Next, crumble the reserved dough over the cranberry filling, creating an even, rustic topping. This crumbled layer will become a crunchy contrast to the tender filling as it bakes, adding texture to your Cranberry Crumble Bars that everyone will love.
Step 10: Bake the Final Dish
Return the pan to the oven and bake for another 45 minutes. To prevent burning, cover the dish loosely with foil for the last 10-15 minutes. The topping should look golden brown while the filling bubbles slightly at the edges, signaling deliciousness.
Step 11: Cool and Glaze
Remove your baked Cranberry Crumble Bars from the oven and allow them to cool on a wire rack for at least 30 minutes. Once cooled, whisk together powdered sugar, milk, and vanilla to create a smooth glaze, and drizzle it generously over the top for an added touch of sweetness.
Step 12: Serve the Treats
Finally, cut the bars into squares to serve. You can enjoy them warm or at room temperature, possibly with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgence. Your inviting Cranberry Crumble Bars are now ready to be savored!

Storage Tips for Cranberry Crumble Bars
Room Temperature: Store your Cranberry Crumble Bars tightly covered at room temperature for up to 4 days to keep them fresh and delicious.
Fridge: If you live in a warmer climate, consider refrigerating the bars to maintain their freshness for up to a week. Just remember to cover them well to prevent drying out.
Freezer: For longer storage, freeze the bars without glaze, wrapped tightly in plastic wrap and then in foil, for up to 3 months. Thaw them before serving for the best taste.
Reheating: To enjoy warm bars, simply reheat in the oven at 350°F (175°C) for about 10 minutes. This brings back their delightful texture and flavor!

Expert Tips for Cranberry Crumble Bars
-
Don’t Overmix: Ensure that you mix the dough just until it comes together. Overmixing can lead to tough bars instead of the tender texture you desire.
-
Fresh Cranberries: Use fresh cranberries whenever possible for the best tartness and flavor. If you opt for frozen, remember to thaw and drain them thoroughly to avoid excess moisture.
-
Watch Baking Time: Keep a close eye on the bars while they bake. It’s better to underbake slightly for a softer texture than to overbake, which can dry them out.
-
Cool Completely: Allow the bars to cool completely before cutting. This helps them hold their shape and makes for cleaner squares when serving.
-
Storage Tips: Store any leftovers in an airtight container at room temperature for up to 4 days. You can also freeze them for longer shelf life—just remember to thaw before serving!
-
Glaze Variations: For a fun twist, consider infusing the glaze with lemon or orange zest for an extra pop of flavor that complements the cranberry filling beautifully.

Cranberry Crumble Bars Recipe FAQs
What type of cranberries should I use?
Absolutely! Fresh cranberries are preferred for their tartness and vibrant flavor. If you’re using frozen cranberries, make sure to thaw and drain them thoroughly to avoid excess moisture in the filling.
How should I store leftover Cranberry Crumble Bars?
To keep your delicious bars fresh, store them tightly covered at room temperature for up to 4 days. If you’re in a warmer climate or want them to last longer, the refrigerator is a good option, and they can stay fresh for about a week.
Can I freeze Cranberry Crumble Bars?
Yes! I often freeze these bars for later enjoyment. Wrap them tightly in plastic wrap and then in foil, and they can be frozen for up to 3 months. Just remember to thaw them before serving for the best results.
What should I do if my dough is too crumbly?
No worries! If your dough turns out crumbly, you might need a splash more of liquid, such as an extra teaspoon of milk or an additional egg yolk to help bind it together. Mix gently until it holds together, but don’t overmix to maintain that tender texture.
Can I make these bars dairy-free?
Very much so! You can easily substitute the unsalted butter with a non-dairy butter or coconut oil, and for the milk in the glaze, opt for almond milk or another plant-based milk. These small swaps will keep the flavors intact while accommodating dietary restrictions.
