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, like these Zebra Cookies, Nana's Butter Tarts, and Crispy Salted Coconut Cookies.
If you love making these easy oatmeal crumble squares, you'll also love these Apple Pomegranate Crumble Bars, also gluten-free!
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.
🛒 Ingredients
Ready to make a batch of these yummy cranberry oat bars? Here's what you'll need:
- cranberries: you can use either fresh or frozen cranberries
- a lemon
- granulated sugar and coconut sugar
- cornstarch
- butter
- vanilla extract
- gluten-free baking flour
- old-fashioned rolled oats
- unsweetened medium coconut
🔪 Instructions
Here's a quick overview of what you'll do. 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.

Not all gluten-free flour blends are the same. They contain varying amounts of ingredients. Some have xanthan gum, which provides structure and helps baked goods to rise, others do not. I tested my recipe with Bob's Red Mill Gluten-Free 1-1 Baking Flour.

Gluten Free Cranberry Lemon Oatmeal Bars
Ingredients
Cranberry Lemon Filling
- 2 cups fresh cranberries
- 2 teaspoon lemon zest
- ¼ cup lemon juice
- ¾ cup granulated sugar
- 2 teaspoon cornstarch
Oatmeal Base and Crumble Topping
- ½ cup butter, melted
- ¼ cup granulated sugar
- ¼ cup coconut sugar
- 1 teaspoon vanilla extract
- 1 cup 1-to-1 gluten-free baking flour, (I use Bob's Red Mill)
- ¾ cup old-fashioned rolled oats, (not quick oats), gluten-free if necessary
- ¼ cup unsweetened medium coconut, for crumble topping
Instructions
- In a medium saucepan, combine sugar, cornstarch and lemon zest. Add lemon juice and cranberries. Stir to combine. Heat to boiling, then reduce heat to low and simmer for 15 minutes until mixture begins to thicken.
- Preheat oven to 350°F. Line an 8-inch square pan with parchment paper.
- Add melted butter to a medium bowl (or melt it in the bowl in the microwave). Stir in sugars and vanilla, then add flour and oats.
- Set aside 1 cup of the oatmeal mixture for the topping. Transfer the remaining amount to the prepared pan, pressing it evenly into the bottom to create a firm base.
- Spread the cranberry mixture on top of the base, taking care to leave a ½ inch margin to prevent the cranberry from leaking out the edges while baking.
- Add ¼ cup coconut to the remaining 1 cup oatmeal mixture. Sprinkle the topping evenly over the cranberry layer. Bake for 30 - 35 minutes or until golden brown. Cool completely before cutting into bars.
