These Cranberry Lemon Oatmeal Bars will be high on my holiday baking list this year. I rarely bake with granulated sugar, except at holiday time, when I like to make some of our favourite family treats. These Zebra Cookies, Nana's Butter Tarts, and Crispy Salted Coconut Cookies or any of these 12 Gluten-free Holiday Cookies and Bars are ones I make regularly.

These cranberry bars are slightly reminiscent of the raspberry coconut bars my Mom used to make every Christmas, but if I recall correctly, there was a lot of butter, a lot of sugar, sweetened long-shred coconut and most of a jar of raspberry jam in those!
Tasty, for sure, but I actually prefer these healthy cranberry oatmeal bars.
Ready to make a batch of these delicious cranberry oat bars? Here's what you'll need:
- cranberries: you can use either fresh or frozen cranberries
- a lemon: you'll use the zest and the juice in the cranberry filling
- granulated sugar and coconut sugar
- pure vanilla extract
- gluten-free baking flour: I've tested this recipe with both Bob's Red Mill 1-1 Gluten-Free Baking Flour and Cup4Cup Gluten-free Flour
- old-fashioned rolled oats: use certified gluten-free rolled oats, if necessary
- unsweetened medium coconut
Here's a quick overview of what you'll do to make these cranberry oatmeal bars. You'll find detailed instructions in the recipe card below.
- Start by making the cranberry filling. You'll cook it on the stovetop in a saucepan, then set it aside while you make the base and topping.
- Next, you'll combine the crumble ingredients: butter, sugar, vanilla, gluten-free baking flour, and rolled oats.
- Reserve 1 cup of the crumble for the topping. Add ¼ cup coconut to this mixture.
- Press the rest into a lined 8-inch square pan.
- Spread the cranberry filling on top, taking care to leave a ½-inch margin all the way around to prevent the filling from leaking out while it's baking.
- Top with the reserved crumble, sprinkling evenly over the top.
- Bake until golden brown. Cool completely before cutting into bars or squares.
