Ingredients You’ll Need

This Strawberry Oatmeal Crumble Bars Recipe relies on simple, everyday ingredients that come together to deliver layers of flavor and texture. Each component plays a vital role, from the hearty oats providing a nutty chewiness, to the fresh strawberries that burst with natural sweetness and a hint of tang.

• 1 1/2 cups all-purpose flour: The base that gives structure to the bars without weighing them down.
• 1 1/2 cups old-fashioned rolled oats: Adds lovely chewiness and a wholesome texture.
• 3/4 cup granulated sugar: Sweetens the oat mixture perfectly, balancing the tartness of strawberries.
• 1/4 cup brown sugar, packed: Brings a deep, caramel-like richness to the crumble.
• 1/2 teaspoon baking soda: Helps the bars rise slightly and keeps them tender.
• 1/4 teaspoon salt: Enhances all the sweet flavors without overpowering.
• 3/4 cup unsalted butter, cold and cubed: Creates that crumbly, buttery texture everyone loves.
• 1 large egg: Binds the ingredients together for perfect sliceability.
• 2 teaspoons vanilla extract: Adds a warm, fragrant finish to the crumb.
• 2 cups fresh strawberries, hulled and diced: The star of the recipe, providing vibrant color and juicy sweetness.
• 1 tablespoon lemon juice: Lifts the strawberry flavor with a bright, citrusy note.
• 1 tablespoon cornstarch: Thickens the strawberry filling so it isn’t runny.
• 1/4 cup granulated sugar (for strawberries): Sweetens the fruit just right without masking its natural taste.

How to Make Strawberry Oatmeal Crumble Bars Recipe

Step 1: Prepare Your Pan and Oven

Start by heating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some paper hanging over the edges. This little trick makes it easier to lift the bars out when they’re perfectly baked and cooled.

Step 2: Mix the Dry Ingredients

In a large bowl, combine the all-purpose flour, rolled oats, sugars, baking soda, and salt. Mix these together until evenly distributed; this mixture is the foundation for both the crust and crumble topping.

Step 3: Cut Butter into the Dry Mix

Add the cold, cubed butter next. Use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture looks like coarse crumbs. These butter bits are what create the wonderful flaky texture once baked.

Step 4: Add Egg and Vanilla

In a separate bowl, whisk the egg and vanilla extract until smooth. Pour this into the crumb mixture and stir it all together. You’ll want the mixture to be crumbly but consistently moist so it binds nicely.

Step 5: Form the Crust

Press about two-thirds of this oat mixture firmly into the bottom of your lined pan. This forms a sturdy yet tender crust that holds up under the juicy strawberry layer.

Step 6: Prepare the Strawberry Filling

In another bowl, toss the diced strawberries with lemon juice, cornstarch, and the extra granulated sugar. This simple step ensures that the fruit’s natural juices thicken as they bake, creating a luscious filling.

Step 7: Assemble the Bars

Spread the strawberry mixture evenly on top of the crust, then sprinkle the reserved oat crumble mixture over the strawberries. Gently press the crumble down just a little to help it stay intact as it bakes.

Step 8: Bake Until Golden and Bubbling

Place the pan in the oven and bake for 35 to 40 minutes. You’ll know they’re done when the top turns a beautiful golden brown and the strawberry filling is bubbly and inviting.

Step 9: Cool and Cut

Let the bars cool completely in the pan to allow the filling to set. Use the parchment paper overhang to lift the entire slab out, then slice into squares. These bars hold beautifully, making them perfect for sharing or savoring over a few days.

How to Serve Strawberry Oatmeal Crumble Bars Recipe

Garnishes

While these bars are delicious on their own, a dollop of whipped cream or a light drizzle of honey can elevate the experience. Fresh mint leaves add a pop of green and a refreshing aroma that complements the strawberries beautifully.

Side Dishes

Serve alongside a scoop of vanilla ice cream or a cup of freshly brewed coffee or tea for a balanced treat. For a breakfast spin, pair them with a creamy yogurt parfait and fresh berries to round out the meal.

Creative Ways to Present

Try layering the crumble bars in a trifle bowl with whipped cream and sliced strawberries for a stunning dessert centerpiece. Alternatively, cut them into bite-size squares and arrange them on a colorful platter for parties, making them perfect finger-food delights.

Make Ahead and Storage

Storing Leftovers

After baking, store any leftover bars in an airtight container at room temperature for up to three days. The oat crust stays pleasantly crisp while the strawberry layer remains wonderfully juicy.

Freezing

To enjoy later, wrap individual bars tightly in plastic wrap and freeze them in a sealed bag for up to three months. Thaw overnight in the refrigerator before serving to maintain the best texture.

Reheating

Warm your bars briefly in the microwave or oven before eating if you want that fresh-baked feel. Ten to fifteen seconds in the microwave or five minutes at 300°F (150°C) in the oven works perfectly without drying them out.

FAQs

Can I use frozen strawberries for this recipe?

Absolutely! If using frozen strawberries, thaw and drain them well to reduce excess moisture, which helps keep your bars from becoming soggy.

What is the best way to cut the bars neatly?

Cooling the bars completely before slicing is key. Use a sharp knife warmed under hot water and wiped dry for clean, smooth cuts without crumbling.

Can I substitute the butter with a healthier fat?

While butter gives the best flavor and texture, you can experiment with coconut oil or a vegan butter substitute, though results may vary slightly in richness and crispness.

Is this recipe gluten-free?

Not as written, since it uses all-purpose flour. For a gluten-free version, try using a gluten-free flour blend and ensure the oats are certified gluten-free.

How long do the bars keep fresh?

Stored in an airtight container, these bars stay fresh for about three days at room temperature. They can last up to a week if refrigerated, though they’re best enjoyed sooner.
