These Easy Cranberry Oatmeal Crumble Bars are slightly tart and perfectly sweet. They make the best dessert and sweet treat for breakfast!
I love using cranberries, especially during the holiday season, in both sweet and savory recipes. They add such a delicious tart flavor to any recipe and pair so well with sweeteners.
This cranberry oatmeal bar recipe was inspired by my Healthy Raspberry Oatmeal Bars. They are slightly chewy, soft and full of delicious oat crumbles. These crumble bars are perfect for a grab 'n' go breakfast or treat after dinner.

How to make cranberry oat bars:
Make the crumble. Mix all of the crumble ingredients in a bowl and add to the bottom of the pan. Make sure to leave some in the bowl for the crumb topping.
Mix the filling. In a bowl, add the cranberries, maple syrup and lemon juice. Mix to combine and pour on top of the crust. Sprinkle with the crumb topping and bake until slightly golden brown.
Serve. Drizzle with melted white chocolate, if desired and enjoy a bar with a cup of coffee or tea.
No- you can also use frozen cranberries. However, the cranberries should be unsweetened and not dried. If you use frozen cranberries, there is no need to thaw them in advance.
The bars can be stored in an airtight container in the fridge for 4-5 days. You can eat the bars straight from the fridge or heat them for 30 seconds in the microwave.
Yes! The bars can be frozen for 2-3 months. Just be sure to use a freezer-safe container or bag to avoid freezer burn. Thaw the bars in the fridge overnight or at room temperature for a few hours.
Be sure to use a pan that makes it easy to remove the bars. You can grease it very well with cooking spray and/or line it with parchment paper. Parchment paper makes it really easy to lift the crumble bars out of the pan.
