Cranberry Oatmeal Bars Recipe

These cranberry crumble bars are soft, slightly chewy, and the hearty oats with big crumbles are a perfect contrast to the juicy cranberry filling. They’re easy, you don’t need a mixer, and the crust and crumble topping are one in the same. One less step and one less bowl to wash. I boiled fresh cranberries with sugar and orange juice. Orange and cranberry are such complementary flavors and the subtle citrus brightens up the overall flavor of the bars. Add orange zest to taste if you want to intensify the orange flavor. The bars aren’t overly sweet and the tart cranberry flavor shines nicely making them an easy grab-and-go breakfast bar, snack, or dessert. Plus, they’re egg-free, which may come in handy for some people.

How to Make Cranberry Bars with Oatmeal Topping

These cranberry oat bars come together so easily! Detailed instructions can be found in the recipe card at the end of the post, but here’s an overview of the recipe steps:

Tips for Making Cranberry Oat Bars

When spooning the cranberry filling over the crust, leave a 1/4-inch bare margin around the edges. The cranberry filling will burn if it’s touching the edges of the pan and will also stick like crazy. Before sprinkling on the crumble topping, I squeeze the mixture in my palm to encourage bigger crumble pieces to form. Note that these bars must cool for at least 2 hours before you can slice and serve them. The cranberry layer needs time to set! 

Storage Instructions

Leftover cranberry bars with oat topping can be stored at room temperature for up to 1 week. They do not need to be refrigerated! The bars also freeze well. I recommend freezing them in the baking pan, then transferring to a zip-top freezer bag (this prevents the crumble topping from being squished when initially sealed in the bag). When ready to eat, thaw on your counter for about an hour before digging in!
