    Sweet, but not too sweet, these gluten-free Cranberry Lemon Oatmeal Bars have notes of bright lemon and they're bursting with cranberries! These oat bars have just the right amount of sweetness, a buttery oatmeal base, and a crumbly coconut topping that puts them over the top. They're soft and slightly chewy.

    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.

    If you love making these easy cranberry lemon bars, 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 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
    • cornstarch
    • butter
    • 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

    🔪 Instructions

    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.

    1. 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.

    2. Next, you'll combine the crumble ingredients:  butter, sugar, vanilla, gluten-free baking flour, and rolled oats.

    3. Reserve 1 cup of the crumble for the topping. Add ¼ cup coconut to this mixture.
    4. Press the rest into a lined 8-inch square pan.

    5. 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.

    Frequently Asked Questions

    How long do they take to make?

    These cranberry bars can be ready for the oven in about 15 minutes! Make today, enjoy a few, and freeze the rest for another day.

    How many bars will this recipe make?

    This recipe makes 9 large bars or 16 small squares.

    Are these bars easy to cut?

    Yes! These cranberry oat bars slice without crumbling, as long as you cool them completely before slicing.

    Can I make them ahead of time? How long will they stay fresh?

    Store these bars in an airtight container at room temperature for a few days, or in the freezer for up to 3 months. Guaranteed not to last that long!

    What brand of gluten-free flour should I use?

    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 both Bob's Red Mill Gluten-Free 1-1 Baking Flour and with Cup4Cup Gluten-Free Flour.

    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.

      Excellent! I made these with a thickened rhubarb mixture with orange zest instead of cranberry and lemon.
