Sweet and Tart Cranberry Crumb Bars with Raspberries

It’s a pretty sure bet that if we ever end up with leftover cranberry sauce, I will turn it into a sweet treat.

One great option is of course, creamy, sweet-tart cranberry swirled cheesecake, but this time, it’s these buttery, oat crumble-topped raspberry and cranberry crumb bars.

These jammy pie bars are made with tart and tangy cranberries, a hint of citrus from fresh orange zest, and a buttery, oatmeal cookie-like crust and crumb topping dotted with raspberries to add some sweetness. A winter-y riff on one of my favorite back-pocket recipes, you’ll find the strawberry, peach, and caramel-apple versions in the recipe archives too.

They’re perfect for lazy bakers (🙋🏻‍♀️) and cranberry lovers alike, and a delicious way to repurpose leftover holiday cranberries.

Why You’ll Love these Cranberry Pie Bars

These cranberry crumb bars are filled with brown sugar, old-fashioned oats, warming spices, and a generous amount of butter. The crust and crumb topping are made from the same mixture in one large bowl. Sandwiched in between sits the cranberry mixture – a combination of tart cranberry sauce (flavored with orange zest, and vanilla) and a handful of sweet, tender raspberries.

They bake into buttery, crumbly, jammy, and flavorful bars that are ideal for sharing during the holidays. Or, if you don’t bother waiting for them to cool, are also delicious warm from the oven, served in big scoops alongside vanilla ice cream for more classic fruit crisp vibes… 

No matter how you slice it, there’s really nothing better than a gooey, fruit filling nestled beneath a buttery blanket of oatmeal cookie-like crumble goodness. Happy baking!!

Ingredients

Scale

Cranberry Crumb Bars

  • 2 cups (180g) rolled oats
  • 2 cups (240g) all-purpose flour
  • 3/4 cup (150g) light brown sugar, packed
  • 1/4 cup (50g) granulated sugar
  • 1/2 tspbaking soda
  • 1/2 tsp ground cinnamon
  • 1/4 tsp ground ginger
  • 1/2 tsp Kosher salt (such as Diamond Crystal)
  • 1 cup (226g or 2 sticks) unsalted butter, softened
  • 1–1/4 cup whole cranberry sauce
  • 1/2 cup fresh raspberries

Easy Cranberry Sauce

  • 6 oz (1–1/2 cups) fresh cranberries
  • 1/4 cup (60g) orange juice
  • 1/2 cup (100g) granulated sugar
  • 1 tsp pure vanilla extract
  • 1/2 tsp orange zest

Instructions

Cranberry Crumb Bars:

  1. Preheat the oven to 350℉. Line a 9×9-inch baking pan with parchment paper, leaving about an inch overhang on two sides. Set aside.
  2. Make the crumble: In a large mixing bowl, whisk together the oats, flour, brown sugar, baking soda, and spices until well-combined.
  3. Cut the butter into cubes, then use a pastry blender or your fingers to incorporate the butter into the dry ingredients. Mix until the mixture is completely moistened, and you’ve formed a shaggy, crumbly dough, that easily sticks together when pinched. This may take a few minutes.
  4. Assemble to bars: Scoop about two thirds of the crumble dough into the prepared baking pan, and press into an even layer along the bottom.
  5. Spread the cranberry sauce onto the crust, leaving about a 1/4-inch border around the edges. Top with the fresh raspberries, then sprinkle the remaining crumb mixture on top, from edge to edge. Press down gently to form an even layer.
  6. Bake for 30-40 minutes, until the cranberry filling is beginning to bubble and the crumble topping is golden brown and has puffed up slightly. 
  7. Remove from the oven and let cool completely before cutting into bars. Enjoy!!

Fresh Cranberry Sauce: ¹

  1. Add the cranberries, orange juice, and sugar to a medium sauce pan. Cook over low heat, stirring occasionally, for 10 minutes, until the sugar has dissolved, and the cranberries have begun to soften.
  2. Turn the heat up to medium, add the vanilla and orange zest, and continue cooking until the cranberries burst, another 10-15 minutes. Let cool to room-temperature before adding to the bars.
  3. The cranberry sauce can be made in advance, and will keep for several days in the refrigerator.

Equipment

Notes

  • Note: if you’re using another homemade cranberry sauce with a thinner/saucier consistency, you may want to add up to a teaspoon of arrowroot starch or cornstarch.
  • Make them gluten-free: replace the flour with a gluten-free all-purpose flour blend such as Bob’s Red Mill or King Arthur Flour. Be sure to measure by weight for the most accurate substitution.
  • Serve with a vanilla-orange glaze: whisk together 1/2 cup (60g) powdered sugar, 1/2 tsp orange zest, 1/2 tsp vanilla extract, and 1 Tbsp milk or orange juice until combined. Drizzle over the crumb bars.
