Ingredients You’ll Need

Gathering a few straightforward yet quality ingredients lays the foundation for these delicious Strawberry Oatmeal Crumble Bars. Each component brings its own magic: the oats add a hearty chew, the brown sugar lends caramel notes, and fresh strawberries provide that vibrant pop of color and freshness.

• ½ cup unsalted butter, melted: Butter adds richness and helps bind the crust and crumble topping together for that perfect golden crunch.
• 1 cup all-purpose flour: Flour is the base that gives structure to the crust and crumble layer.
• ¾ cup old-fashioned oats: Oats bring a wholesome texture and a gentle nutty flavor that complements the sweetness beautifully.
• ½ cup granulated sugar: This sugar level balances the tartness of the strawberries while sweetening both crust and filling.
• ¼ cup light brown sugar, packed: Brown sugar adds moisture and a hint of molasses flavor which enriches the crumble topping.
• ½ teaspoon salt (or to taste): A pinch of salt enhances and rounds out all the flavors in the bars.
• 2 cups coarsely chopped fresh strawberries: Fresh strawberries provide juiciness and the signature fruity flavor that makes this dessert irresistible.
• ⅓ cup granulated sugar: Combined with the strawberries, it creates a sweetened, syrupy filling.
• 2 tablespoons lemon juice: Lemon juice adds a subtle zing that brightens the strawberry layer wonderfully.
• 2 teaspoons cornstarch: Cornstarch thickens the filling so it sets nicely without becoming runny.

How to Make Strawberry Oatmeal Crumble Bars

Step 1: Prepare the Crust and Crumble Topping

Start by preheating your oven to 350°F and lining an 8-inch square pan with foil for an easy cleanup. Melt the butter in a microwave-safe bowl, then combine it with the flour, oats, sugars, and salt to form a sandy mixture with some chunkier crumble bits. Set aside one generous cup of this mixture for the topping, and firmly press the rest into the pan to create an even, smooth crust that will hold the strawberry filling perfectly.

Step 2: Make the Strawberry Filling

Use the same bowl to toss together chopped strawberries, sugar, lemon juice, and cornstarch until well coated. The sugar might not dissolve fully right away, but don’t worry; it will turn into a delicious filling once baked. Spread this juicy strawberry mixture evenly over the pressed crust.

Step 3: Add the Crumble Topping and Bake

Sprinkle the reserved crumble mixture over the strawberry layer, squeezing it in your palm beforehand to encourage bigger, rustic crumble pieces. Bake the bars for about 50 minutes or until the edges are set, the topping shows a pale golden color, and the strawberry filling bubbles nicely around the edges. If your strawberries are extra juicy, baking time might extend a bit—watch your bars closely rather than relying solely on the clock.

Step 4: Cool and Slice

Once baked, place the pan on a wire rack and allow the bars to cool completely—at least one hour—to ensure clean cutting and to help them set up perfectly. Attempting to slice too early will result in messy, crumbly bars that refuse to hold their shape.

How to Serve Strawberry Oatmeal Crumble Bars

Garnishes

Elevate your Strawberry Oatmeal Crumble Bars with a dollop of whipped cream or a scoop of creamy vanilla ice cream for a delightful contrast to the tart strawberry layer. Fresh mint leaves or a light dusting of powdered sugar can also add a lovely finishing touch, making each bite irresistible.

Side Dishes

Pair these bars with a steaming cup of tea or a fresh, fruity smoothie for a wholesome dessert experience. They also work wonderfully alongside a simple bowl of Greek yogurt topped with honey and a sprinkle of cinnamon if you want a breakfast-inspired treat.

Creative Ways to Present

For entertaining, consider cutting the bars into mini squares and arranging them on a rustic wooden board with fresh strawberries and small bowls of yogurt or cream. You can also skewer cubes of the bars and fresh berries for a fun, handheld dessert option at parties.

Make Ahead and Storage

Storing Leftovers

Leftover Strawberry Oatmeal Crumble Bars should be stored in an airtight container at room temperature for up to two days or in the refrigerator for up to five days. Keeping them covered well helps maintain the crispness of the crumble while preserving the juicy filling.

Freezing

Freeze the bars by wrapping them securely in plastic wrap and placing them in a freezer-safe container or bag. They freeze beautifully for up to three months. Thaw them overnight in the refrigerator before enjoying, so they retain their moist yet crumbly texture.

Reheating

If you prefer warm bars, gently reheat individually sliced bars in the microwave for about 15 to 20 seconds or in a low oven (around 300°F) for 10 to 15 minutes. Warmed bars bring out the delightful aroma of oats and strawberries, making them even more comforting and tasty.

FAQs

Can I use frozen strawberries instead of fresh?

While fresh strawberries are ideal for the best texture in these bars, you can use frozen strawberries if fresh aren’t available. Just be sure to thaw and drain them well to avoid excess moisture making the bars too soggy.

What can I substitute for cornstarch in the filling?

If you don’t have cornstarch, arrowroot powder or tapioca starch work well as thickening agents. Use the same amount as cornstarch to help your strawberry filling set properly.

Are these bars gluten-free?

The recipe isn’t naturally gluten-free because of the all-purpose flour, but you can substitute with a gluten-free flour blend to make them safe for gluten-sensitive eaters, keeping in mind the texture might vary slightly.

How can I make the crumble topping more crunchy?

To achieve a crunchier crumble topping, make sure your butter is fully melted and well mixed with the oats and sugars. You can also add a small handful of chopped nuts like pecans or walnuts for extra texture and flavor.

Can I substitute brown sugar with something else?

If you prefer, coconut sugar or maple sugar can replace brown sugar to add a different but delicious depth of sweetness to the crumble topping. Just keep the measurements the same for the best results.
