Key Ingredients
- Brown sugar & organic cane sugar – A blend for balanced sweetness; coconut sugar works as a less-sweet swap.
- All-purpose flour – Substitute 1:1 gluten-free flour to make these bars gluten-free.
- Rolled oats – Adds texture; use certified gluten-free oats if needed.
- Ground flax – Optional, for extra nutrition and texture.
- Butter – Gives a golden, tender crust; use dairy-free butter for a vegan option.
- Orange zest & juice – Brightens the filling and balances the tart cranberries.
- Fresh cranberries – Provide tartness and a festive color.
How To Make Cranberry Bars
Preheat the oven to 375°F. Prepare your crust and topping by combining the dry ingredients, then add the wet ingredients and cut in the butter. Press just over half of the mixture into a parchment-lined 9×13 pan to form the crust.

In a medium bowl combine cornstarch and sugar, then stir in orange juice, orange zest, vanilla, and a pinch of nutmeg. Fold in the fresh cranberries so they are evenly coated. Spread the cranberry filling over the pressed crust. Sprinkle the remaining crumble mixture—combined with a few tablespoons more brown sugar—over the top in an even layer.

Bake on the middle oven rack for 40–45 minutes, until the topping is golden brown and the cranberry filling is bubbling slightly. Allow the pan to cool completely before lifting out with the parchment and cutting into squares.

These bars slice cleanly once cooled and keep well in the refrigerator, making them a convenient make-ahead dessert for holiday gatherings.

Remove from the oven, cool to room temperature, then cut into bars. These cranberry crumble bars are a favorite holiday recipe and are great for sharing with friends and family.
