Ingredients You’ll Need
Every ingredient in these bars plays a star role, creating the ultimate harmony of sweet, chewy, and crumbly. Nothing complicated here—just baking staples that pull together delicious magic in under an hour!
- Unsalted butter (1 cup, softened): Gives the crust its melt-in-your-mouth richness and brings all the dry ingredients together beautifully.
- Packed brown sugar (1 cup): Adds deep caramel flavor and contributes to the chewy texture that makes these bars so addictive.
- Vanilla extract (1 teaspoon): Rounds out the flavors, lending warmth and a subtle, aromatic sweetness.
- All-purpose flour (1 3/4 cups): The backbone of the base and crumble, giving body to every bite.
- Old-fashioned oats (1 1/2 cups): For a rustic, toothsome texture and a hearty contrast against the soft, sweet jam.
- Baking soda (1/2 teaspoon): Helps the crust stay tender rather than dense.
- Salt (1/4 teaspoon): Balances the sugar and brightens all the flavors.
- Strawberry jam or preserves (1 1/4 cups): The luscious, fruity heart of the bars—choose your favorite or even try homemade for extra love.
How to Make Strawberry Oatmeal Jam Bars
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F, giving it plenty of time to get nice and hot. Line a 9×13-inch baking pan with parchment paper, leaving a bit of overhang for easy lifting later, or lightly grease it if you prefer. This will make removing the bars (and cleaning up!) a total breeze.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream the softened butter and packed brown sugar together until the mixture is light, airy, and a little fluffy. This step makes all the difference—creaming incorporates air and ensures your base is tender yet sturdy.
Step 3: Add the Vanilla
Mix in the vanilla extract, stirring until it disappears into the buttery cloud. That little splash infuses the base with a whisper of warmth that really elevates the whole batch.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the flour, oats, baking soda, and salt. This quick mix ensures everything is evenly distributed, so you get the right rise and flavor throughout the bars.
Step 5: Bring Wet and Dry Together
Gradually add the dry ingredients to your creamed butter and sugar. Stir until combined—it’ll look crumbly but should clump together when pinched. This crumble becomes both your base and topping.
Step 6: Press the Crust
Take about two-thirds of the oat mixture and press it evenly into the bottom of the prepared pan. Don’t worry about perfection; a firm, even layer is what gives the bars their satisfying bite when sliced.
Step 7: Layer the Strawberry Jam
Spread the strawberry jam gently over the crust, leaving a small border around the edges to prevent bubbling over. The layer of jam becomes the juicy, sweet surprise sandwiched between every crumbly bite.
Step 8: Add the Crumble Topping
Sprinkle the remaining oat mixture evenly over the strawberry layer. The topping bakes up golden and crisp, providing a lovely contrast to the gooey jam below.
Step 9: Bake Until Golden
Bake for 30 to 35 minutes, or until the top is lightly golden and the jam is bubbly. Let the bars cool completely in the pan—trust me, patience here pays off with clean, beautiful slices.
How to Serve Strawberry Oatmeal Jam Bars

Garnishes
For a simple, extra-special touch, try a dusting of powdered sugar or a drizzle of melted white chocolate on top right before serving. Fresh sliced strawberries and a mint sprig transform these bars into a bakery-worthy dessert platter with zero fuss.
Side Dishes
Strawberry Oatmeal Jam Bars pair perfectly with a scoop of vanilla ice cream, a dollop of whipped cream, or just a tall glass of ice-cold milk. For brunch, serve them alongside fresh fruit salad or a tangy yogurt parfait for a lovely contrast of flavors.
Creative Ways to Present
Cut the bars into hearts, diamonds, or mini squares for a festive touch at showers and parties. Stack them on a cake stand for a show-stopping centerpiece, or wrap individual bars in parchment and twine for the sweetest homemade gift.
Make Ahead and Storage
Storing Leftovers
Keep leftover Strawberry Oatmeal Jam Bars fresh by storing them in an airtight container at room temperature, where they’ll stay soft and delicious for up to four days. No fridge required unless your kitchen is extra warm!
Freezing
Want to save some bars for a rainy day? Place cooled, cut bars in a freezer-safe container or zip-top bag, separating layers with parchment paper. They’ll keep well in the freezer for up to three months—just thaw at room temperature before enjoying.
Reheating
If you prefer your Strawberry Oatmeal Jam Bars warm and gooey, pop a bar in the microwave for about 10–15 seconds. For a crispier finish, warm them in a 300°F oven for 5–7 minutes. Serve right away for the ultimate treat.
FAQs
Can I use a different type Dessert
Absolutely! While strawberry gives these bars their signature flavor, feel free to try raspberry, blueberry, or even apricot jam. Just make sure the texture is thick enough not to run too much during baking.
Can I make Strawberry Oatmeal Jam Bars gluten-free?
Yes, swap in your favorite 1:1 gluten-free all-purpose flour, and be sure your oats are certified gluten-free. The results should be just as delicious and easy!
How do I know when the bars are fully baked?
The top will turn lightly golden and the jam should be bubbling around the edges. Resist the urge to overbake—the bars will firm up more as they cool.
Can I add nuts to the recipe?
Definitely! For a nutty twist, stir about 1/2 cup of chopped pecans or walnuts into the topping. They add wonderful crunch and pair beautifully with the oats and jam.
Do Strawberry Oatmeal Jam Bars travel well?
Yes, these bars are sturdy enough to pack for picnics, potlucks, or lunchboxes. Just layer them with parchment or wax paper so they stay looking (and tasting) perfect on the go.
