Before you throw out any leftover cranberry sauce, I need you to check out these vegan cranberry crumble oatmeal bars first. I make them with almond flour, oats, and orange juice, and they need just 45 minutes to turn into a buttery crumble topping with a sweet-tart filling. My family looks forward to this recipe almost as much as Thanksgiving dinner itself.

Every holiday table seems to have extra cranberry sauce waiting for a second chance, and these healthy vegan cranberry crumble oatmeal bars provide the perfect solution. Unlike my standard vegan granola bars, I use oats to create a crisp crumble topping that sits on the tart filling, creating a wholesome dessert that works for breakfast or an afternoon snack. Make sure you save this recipe so that you never have cranberry sauce go to waste ever again.

The idea for this recipe came after I realized my family never reached for leftover cranberry sauce once the holiday meal ended. I was always trying different savory snacks to get the most out of it, but nothing ever really stuck. Then I decided to go the sweet route instead. But it’s not like I could just use it in something like healthy cranberry orange muffins. I had to think outside the box. And as soon as the sauce was repacked in a sweet crumble, the boys had a newfound love for it. Who would have guessed? Ha!

🥘 Ingredients

This is every ingredient I use to create crisp and fruity healthy vegan cranberry crumble oatmeal bars:

Cranberry sauce: I use homemade or store-bought cranberry sauce as the fruity center of these bars.

Orange juice: I stir this into the cranberry sauce for extra citrus flavor and a brighter filling. 

Almond flour: This creates a tender, buttery-style crumble while keeping the recipe gluten-free.

Oats: I like using rolled oats for texture, and choose certified gluten-free oats when needed. 

Coconut sugar: Coconut sugar adds a rich caramel-like sweetness.

Baking powder: I add this to keep the crumble light.

Sea salt: Just a pinch helps balance the sweetness and highlight the cranberry flavor. 

Applesauce: I use unsweetened applesauce to help bind the crumble while adding moisture. 

Almond butter: I mix this into the crumble for richness and a delicious nutty flavor.

🔪 How To Make

I can have these healthy vegan cranberry crumble oatmeal bars ready for the oven in just a few minutes. This is how I do it:

Mix cranberry layer: First, I preheat my oven to 350F and prepare an 8×8 baking dish. Then I stir the cranberry sauce and orange juice together until the mixture is thick and smooth.

Mix dry ingredients: Then, in a separate bowl, I combine the almond flour, oats, coconut sugar, baking powder, and sea salt.

Cut in wet ingredients: I add the applesauce and almond butter, then use a fork to work everything together until the mixture looks crumbly instead of forming a dough. 

Add base layer: Next, press 2/3 of the crumble mixture firmly into the prepared baking dish to create the crust.

Spread cranberry layer: I spread the cranberry mixture into an even layer over the crust.

Add crumble topping: I sprinkle the remaining crumble across the top, pressing very lightly so it stays crumbly.

Bake: Then I bake the crumble for 35-40 minutes until the top is lightly golden. I let the bars cool completely before slicing and serving.

📖 Variations

I have baked these healthy vegan cranberry crumble oatmeal bars in so many different ways over the holidays, and these are the version my family loves the most:

Cranberry apple: I fold 1 cup of small diced honeycrisp apples into the cranberry filling before spreading it over the crust. The apples soften as they bake and make the bars taste similar to a fruit crisp. My boys love eating this with a drizzle of cinnamon maple glaze. 

Orange pecan: For even more brightness, I add 1 teaspoon of orange zest to the crumble mixture and sprinkle 1/2 cup of chopped pecans over the top before baking. This is extra crunchy and adds even more of a festive fall flavor to the bars. 

Mixed berry: If I do not have that much cranberry sauce leftover, I replace half a cup with thick raspberry or black berry preserves. This softens the tart cranberry flavor and creates a richer fruit filling that my kids love, especially around Christmas. 

🍽 Serving Suggestions

If you are serving this healthy vegan cranberry crumble oatmeal bars for breakfast, I highly recommend pairing it with something just as fruity and delicious, like a mixed berry smoothie without yogurt. And if you are enjoying a few squares for an afternoon treat, complement the berry flavors with a glass of strawberry milk tea. 

Since this crumble is already quite perfect, I like serving it with simple toppings and accompaniments. Even my kids, who usually add anything sweet to their desserts, prefer it with a simple dollop of vegan whipped cream and a drizzle of vegan honey. And since the weather is cooler during Thanksgiving, they enjoy it with a warm mug of oat milk with my homemade hot chocolate mix. 

🧊 Storing And ♨️ Reheating

Refrigeration: I keep the bars in an airtight container in the refrigerator for up to 5 days. They become even easier to slice after they have chilled. 

Freezing: I freeze individual bars with parchment paper between each layer in a freezer-safe container for up to 3 months. 

Reheating: If frozen, I thaw the bars in the refrigerator overnight, then serve cold. But if I want them warmer, I heat one bar at a time in the microwave for 15-20 seconds, or in a 300F oven for a few minutes to crisp up the crumble.
