Cranberry Oatmeal Bars Recipe
Introduction
These cranberry oatmeal bars are easy to make and bursting with vibrant cranberry flavor, topped with a deliciously crumbly oat crust. With a buttery base and a hint of cinnamon, they’re perfect for holiday gatherings and a delightful alternative to traditional pies.

Ingredients
- 1 cup unsalted butter, melted
- 1 1/2 cups all-purpose flour (gluten-free if needed)
- 2 cups old-fashioned rolled oats (gluten-free certified if needed)
- 1 cup light brown sugar, packed
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1 1/2 cups whole cranberry sauce (homemade or store-bought)
Instructions
- Step 1: In a large bowl, combine the melted butter, flour, rolled oats, brown sugar, cinnamon, and salt. Stir until the mixture becomes crumbly.
- Step 2: Press about 1 1/2 cups of the crumb mixture firmly into the bottom of a parchment-lined 9×9-inch baking pan to form the crust.
- Step 3: Spread the cranberry sauce evenly over the crust layer.
- Step 4: Sprinkle the remaining crumb mixture evenly over the cranberry sauce. Bake in a preheated oven at 350°F (175°C) for 50-55 minutes, or until the top is golden and the cranberry layer is bubbly.
- Step 5: Allow the bars to cool completely before slicing and serving.
Tips & Variations
- Use vegan butter to make these bars dairy-free and vegan-friendly.
- Swap cranberry sauce for blueberry or cherry preserves for a different fruity twist.
- Add white chocolate chips into the crumb mixture for extra sweetness.
- Include chopped walnuts or pecans in the topping for added crunch.
- Use certified gluten-free oats and flour to make the recipe gluten-free.
- For a healthier version, replace brown sugar with coconut sugar and butter with coconut oil, and try a naturally sweetened homemade cranberry sauce.
- Check the bars at 45 minutes as oven temperatures vary; they’re done when golden and bubbly.
- Cool completely before cutting; chilling in the fridge or freezer speeds this up.
- Homemade cranberry sauce adds fresh tartness and flavor.
Storage
Store the bars in an airtight container at room temperature or in the refrigerator for up to 2 days. They’re great made ahead of time to set fully before slicing. To reheat, warm individual servings gently in the microwave if desired.

FAQs
Can I make these cranberry bars ahead of time?
Yes, these bars store well and can be made up to 2 days in advance. Keeping them covered at room temperature or in the fridge helps them set perfectly before cutting.
Can I use quick oats instead of old-fashioned rolled oats?
Old-fashioned rolled oats are recommended because they hold their texture better during baking and create a crumbly topping. Quick oats may result in a softer, less textured bar.

Ingredients
Crust and Crumble
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups all-purpose flour (use gluten-free flour for gluten-free version)
- 2 cups old-fashioned rolled oats (certified gluten-free if needed)
- 1 cup light brown sugar, packed
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
Filling
- 1 1/2 cups whole cranberry sauce (store-bought or homemade)
Instructions
- Make the Crust and Crumble: In a large bowl, combine the melted unsalted butter, all-purpose flour, old-fashioned rolled oats, light brown sugar, ground cinnamon, and salt. Stir until the mixture forms a crumbly texture, ensuring all ingredients are evenly incorporated.
- Press the Crust: Line a square metal baking pan with parchment paper. Press approximately all but 1 cup of the crumb mixture firmly into the bottom of the pan to create an even crust layer.
- Add Cranberry Layer: Spread the whole cranberry sauce evenly over the pressed crust, ensuring full coverage for balanced flavor in every bite.
- Final Layer and Bake: Sprinkle the remaining crumb mixture over the cranberry sauce to form the topping. Bake the bars in a preheated oven at 350°F (175°C) for 50 to 55 minutes until the top is golden and the cranberry sauce is bubbling. Allow the bars to cool completely in the pan before slicing and serving.
Notes
- Check your oven around 45 minutes as baking times may vary; the bars are done when the topping is golden and cranberry sauce bubbles.
- Cool bars fully before cutting; refrigerating or freezing speeds cooling and setting.
- For a vegan version, substitute vegan butter for the unsalted butter.
- Try different fillings like blueberry or cherry preserves for variation.
- Add white chocolate chips or chopped walnuts/pecans into the crumb mixture for extra flavor and texture.
- Use certified gluten-free oats and flour to make a gluten-free version.
- Swap brown sugar for coconut sugar and butter for coconut oil for a healthier alternative.
- Homemade cranberry sauce adds fresh tartness and flavor.
