Strawberry Rhubarb Oatmeal Bars Ingredients
• Let’s gather the goodness for these strawberry rhubarb oatmeal bars with fresh fruit!
For the Crust
- All-Purpose Flour – Provides structure to the crust; whole wheat flour offers a healthier option.
- Quick Oats – Delivers a sturdy texture for easy handling; can be substituted with rolled oats with a slight texture change.
- Baking Powder – Acts as a leavening agent for a light and airy crust.
- Cinnamon – Adds a warm, comforting flavor to the bars.
- Salt – Enhances overall flavors, making everything pop.
- Brown Sugar – Contributes sweetness and moisture; swap for coconut sugar for a lower glycemic index.
- Large Egg – Binds all crust ingredients together; consider a flax egg for a vegan option.
- Melted Butter – Adds richness and moisture; easily replaced with coconut oil or vegan butter.
- Maple Syrup – Introduces a natural sweetness; honey or agave syrup can work as alternatives.
For the Filling
- Diced Strawberries – The primary sweet component; opt for fresh, ripe berries for the best flavor.
- Diced Rhubarb – Infuses a lovely tartness to balance the sweetness; always choose firm stalks—leaves are toxic.
- Granulated Sugar – Optional for sweetening the fruit filling, depending on your fruit’s sweetness.
- Lemon Juice – Brightens the filling’s flavor and balances sweetness; fresh or bottled versions are fine.
- Cornstarch – Thickens the filling for a delightful jammy texture when baked.

How to Make Strawberry Rhubarb Oatmeal Bars
-
Preheat the oven to 350°F. Line an 8×8 inch baking pan with parchment paper, allowing some overhang to make removal easier later.
-
Whisk together in a large bowl the all-purpose flour, quick oats, baking powder, cinnamon, and salt. This dry mixture will give structure and flavor to your crust.
-
Combine the melted butter, maple syrup, and egg with the dry ingredients. Stir until everything is well blended into a deliciously sticky batter.
-
Press 1.5 cups of this mixture evenly into the bottom of your lined baking pan to form the crust. Set aside about 0.5 cups for the topping later.
-
Mix the diced strawberries and rhubarb in a separate bowl with the lemon juice. This fresh combination will sing with flavor as it bakes.
-
Combine granulated sugar and cornstarch in another small bowl. Sprinkle this mixture over the fruit and stir to coat, ensuring every piece is sweetened.
-
Spread the fruity filling evenly over the crust in the baking pan. Then, sprinkle the reserved oatmeal mixture over the top to create a delightful crumbly layer.
-
Bake for 20-25 minutes. Look for a beautiful golden brown topping with the filling looking soft and jammy as it cooks.
-
Cool in the pan before slicing into squares. This will help the bars set up properly for that perfect chewy texture!
Optional: Serve warm with a dollop of whipped cream for an extra touch of delight.

Strawberry Rhubarb Oatmeal Bars Recipe FAQs
What ripe ingredients should I look for?
Absolutely! When selecting strawberries, aim for plump, bright red ones without any dark spots or mold. The ripeness of strawberries will greatly affect the sweetness of your filling. For rhubarb, look for firm stalks—avoid leaves as they are toxic. The stalks should be glossy and a vibrant pink or green color.
How should I store my strawberry rhubarb oatmeal bars?
To keep your strawberry rhubarb oatmeal bars fresh, store them in an airtight container on the counter for up to 3 days. If you want to extend their lifespan, pop them in the fridge where they can last for up to 5 days. Just make sure to keep them sealed tightly to prevent them from drying out!
Can I freeze these bars and if so, how?
Yes! To freeze your strawberry rhubarb oatmeal bars, let them cool completely, then place them in a single layer in a freezer-safe container or freezer bag. They can be stored this way for up to 3 months. When you’re ready to enjoy, thaw them in the refrigerator overnight or warm them in the microwave for about 10-15 seconds for that freshly-baked taste.
What if my bars crumble when I cut them?
Very! If your bars crumble, it might be due to not allowing them to cool down completely before slicing. Wait for at least 30 minutes after baking—this way they can set up properly and maintain a chewy texture. Also, ensure that you pressed the crust mixture well into the pan initially; this helps provide a solid base.
Are there any dietary considerations I should be aware of?
For those with allergies, note that this recipe contains gluten due to the all-purpose flour. However, you can easily adapt it by using gluten-free flour or oats if needed. Additionally, if you’re cooking for someone with egg allergies, a flax egg is a great vegan substitute. Always consult with diners regarding any specific dietary restrictions!
How do I enhance the flavor if my strawberries are bland?
If you find yourself with strawberries that aren’t as sweet as you’d like, consider adding a splash of vanilla extract when mixing them with the rhubarb. The vanilla will elevate the overall flavor profile and compensate for the lack of sweetness in the fruit!
