Cranberry Crumble Bars have a brown sugar oat crust that does a double act as the base and crumb topping, with a jammy cranberry filling. It's a sweet, tart and gorgeous treat that is easy to make ahead. Gluten free, too.

Ingredients

Oat Crumble Mixture

  • 1 ¼ cups old fashioned rolled oats
  • ¾ cup 1-to-1 All-Purpose Gluten-Free Baking Flour
  • ½ cup brown sugar
  • ¼ teaspoon fine sea salt
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground ginger
  • ½ cup unsalted butter cubed
  • almond slices for garnish

Filling

  • 12 ounces fresh cranberries
  • cup pure maple syrup
  • 1 ½ tablespoons orange zest about 2 oranges
  • ½ cup orange juice
  • ½ teaspoon almond extract or vanilla extract
  • 1 tablespoon tapioca flour

Glaze

  • ½ cup powdered sugar
  • 2 teaspoons orange juice

Instructions

  • Preheat oven to 350ºF and line 8x8 baking pan with parchment paper; set aside.
  • Make crumble: In a large bowl combine oats, flour, brown sugar, salt, spices and cubed butter. Use dough blender to bring mixture together, using hands at the end as necessary – mixture should be crumbled but hold when pressed together. 
  • Bake crust: Add ⅔ of crumble mixture to lined baking pan and press evenly into all 4 corners. Bake for 10-12 minutes; remove from oven and set aside to cool.
  • Make filling: While the pan is cooling, make the filling: In a small saucepan over medium heat add cranberries, maple syrup, orange zest, orange juice and almond extract. Cook down for 8-10 minutes, stirring frequently. Remove from heat and stir in tapioca flour until dissolved – mixture will get thicker here.
  • Assemble and Bake: Pour filling over pre-baked crust and add the rest of the crumbled topping, making clumps as desired. Sprinkle with almond slices, if desired. Bake for 25-30 minutes, or until edges start to bubble and topping is golden brown.
  • Cool and chill: Allow pan to cool at room temperature for one hour. Then transfer the pan to the fridge for another 45 minutes. Pan must be chilled before cutting into bars. 
  • Make the glaze: Once the bars have chilled completely, mix together powdered sugar and orange juice to make the glaze.
  • Slice: Lift parchment paper from sides and carefully place bars on cutting board; use a large sharp knife to cut into 16 squares. Drizzle with glaze. Bars have a nice crust and jammy filling - enjoy!

Notes

STORAGE - Cranberry bars will keep in an airtight container stored in the fridge for up to 5 days. I do recommend keeping these in the fridge, rather than at room temperature, so the cranberry jam and icing stay set.
Make Ahead Instructions: Cranberry filling can be made up to 3 days in advance. Cranberry bars can also be made 1-2 days prior to serving on the big day. Store any leftovers as instructed above.
