Delicious Strawberry Oatmeal Bars
There’s something about the combination of sweet strawberries and hearty oats that just feels like comfort in every bite. That’s exactly why I love making Strawberry Oatmeal Bars—they’re chewy, slightly crisp on top, and bursting with fresh strawberry flavor. Whether you’re looking for a wholesome breakfast treat, a snack, or a dessert, these bars hit all the right notes.
What makes them extra special is how simple they are to prepare. With pantry staples like oats, flour, and sugar, plus fresh strawberries and a little butter, you can whip up a batch in under an hour. I often swap in gluten-free oats or dairy-free butter depending on who I’m serving, and honestly, they turn out just as delicious every time.
These bars are perfect for summer picnics, lunchboxes, or just a cozy afternoon treat. And the best part? You get that homemade, rustic look without any fancy equipment or complicated steps.
In this recipe, I’ll walk you through everything step by step—from mixing the oat base to creating a luscious strawberry layer and finishing with the perfect bake. By the end, you’ll have bars that are chewy, fruity, and impossible to resist.
Before we dive into baking, let’s make sure we have everything ready. Having the right ingredients and tools makes the process smoother and ensures perfect bars every time.
Ingredients for Strawberry Oatmeal Bars
For the Oat Base:
1 cup old-fashioned rolled oats (gluten-free if needed)
¾ cup white whole wheat flour (or all-purpose flour, or 1:1 gluten-free baking flour)
⅓ cup light brown sugar
¼ teaspoon ground ginger
¼ teaspoon kosher salt
6 tablespoons unsalted butter, melted (or melted coconut oil for vegan/dairy-free)
For the Strawberry Filling:
2 cups small-diced strawberries (about 10 ounces), divided
1 teaspoon cornstarch
1 tablespoon freshly squeezed lemon juice (from about ½ small lemon)
1 tablespoon granulated sugar, divided
Optional Garnish:
Chopped fresh chives or parsley (for a fresh, decorative touch)
Required Kitchen Tools
Having the right tools makes baking these bars a breeze. Here’s what I always keep on hand:
Mixing Bowls: A large bowl for the oat base and a smaller bowl for the strawberries.
Measuring Cups and Spoons: Precision is key for the perfect texture.
Baking Dish: I recommend an 8x8-inch square pan for evenly baked bars.
Spatula or Wooden Spoon: For mixing ingredients without overworking the dough.
Small Saucepan (Optional): If you want to gently heat the strawberry mixture before spreading.
Parchment Paper: Makes removing the bars from the pan effortless.
With everything measured and your tools ready, you’ll be all set to create these irresistible strawberry oatmeal bars.
Preparation & Baking Instructions
Now comes the fun part—turning simple ingredients into chewy, fruity bars that everyone will love. I’ll walk you through each step so your strawberry oatmeal bars turn out perfect every time.
Step 1: Preheat and Prep
First, preheat your oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper, leaving a little overhang on the sides to make it easy to lift the bars out later.
Step 2: Make the Oat Base
In a large mixing bowl, combine:
1 cup rolled oats
¾ cup white whole wheat flour
⅓ cup light brown sugar
¼ teaspoon ground ginger
¼ teaspoon kosher salt
Stir these dry ingredients together until evenly mixed. Then, pour in 6 tablespoons melted butter (or coconut oil) and mix until the mixture is crumbly but sticks together slightly when pressed. Set aside ¾ of this mixture—this will become the base of your bars.
Press the reserved mixture firmly into the bottom of the prepared pan to form an even layer. This will bake into a slightly crisp, golden oat base that holds the strawberry filling perfectly.
Step 3: Prepare the Strawberry Filling
In a small bowl, combine:
1½ cups diced strawberries
1 teaspoon cornstarch
1 tablespoon granulated sugar
1 tablespoon lemon juice
Mix gently until the strawberries are coated and the cornstarch is fully dissolved. This will help thicken the filling as it bakes. Then, spread the strawberry mixture evenly over the oat base. Sprinkle the remaining ½ cup diced strawberries on top for extra fruity bursts.
Step 4: Add the Crumb Topping
Take the remaining ¼ of your oat mixture and sprinkle it evenly over the strawberry layer. This crumb topping will bake into a lightly crisp, golden finish—perfect for texture contrast.
Step 5: Bake to Perfection
Place the pan in the preheated oven and bake for 35–40 minutes, or until the topping is golden and the filling is bubbling slightly at the edges. Once baked, remove the pan from the oven and let the bars cool completely in the pan before lifting them out using the parchment overhang.
Step 6: Slice and Serve
Once cooled, slice the bars into squares or rectangles. You can enjoy them as-is or garnish with chopped fresh chives or parsley for a playful, fresh twist. These bars are perfect for breakfast, a snack, or a light dessert.
Serving, Storage & Tips
After baking these strawberry oatmeal bars, the last step is all about enjoying them and keeping them fresh. I’ve learned a few tricks over time that make them even better.
Serving Suggestions
I love serving these bars slightly chilled or at room temperature. They’re chewy, fruity, and have a subtle crunch from the oat topping. Here are a few ways I enjoy them:
As a Breakfast Treat: Pair with a cup of coffee or tea for a wholesome start to the day.
Snack Time: Perfect for a mid-afternoon energy boost—portable and mess-free.
Dessert: Add a dollop of Greek yogurt, vegan cream, or a drizzle of chocolate for a sweeter twist.
Storage Instructions
To keep your bars fresh:
At Room Temperature: Store in an airtight container for up to 3 days.
In the Refrigerator: They can last up to a week—just make sure they’re sealed well to prevent drying out.
Freezing: Wrap individual bars in parchment or plastic wrap and place them in a freezer-safe container. They freeze well for up to 2 months. Thaw at room temperature before serving.
Extra Tips for Perfect Bars
Ripe Strawberries Matter: The sweeter and juicier, the better your filling will taste.
Press the Base Firmly: Ensures the bars hold together when sliced.
Don’t Skip Cooling: Cooling completely allows the filling to set and prevents the bars from falling apart.
Experiment with Flavors: Add a pinch of cinnamon or nutmeg to the oat mixture, or swap some strawberries for raspberries for a tangy variation.
With these tips, making Strawberry Oatmeal Bars becomes a simple, rewarding experience. They’re perfect for sharing—or sneaking a few for yourself. Once you taste the chewy oat base, sweet-tart strawberries, and golden crumb topping, you’ll understand why I keep coming back to this recipe again and again.
