• Unsalted Butter: Rich base that creates tender crumb and adds luxurious flavor to the bars.
• Vanilla Extract: Aromatic enhancement that deepens the overall taste profile.

• Raspberry Preserves: Vibrant fruity filling that provides sweet-tart flavor and moisture to the dessert bars.

• Salt: Subtle seasoning that balances and enhances the sweetness of the entire dessert.

How to Assemble and Bake Raspberry Oatmeal Bars

Step 1: Prepare the Oven and Pan

Crank up your oven to 350°F. Grab an 8×8-inch pan and line it with aluminum foil, giving it a quick spray of nonstick cooking spray. This will make your life easier when it’s time to remove those delectable bars.

Step 2: Melt the Butter

Zap some butter in a microwave-safe bowl for about a minute until it’s completely melted and smooth.

Step 3: Create the Sweet Base

• Granulated sugar
• Brown sugar
• Vanilla extract

Mix until everything is beautifully combined and looks like a golden, glossy mixture.

Step 4: Build the Oatmeal Mixture

• Flour
• Oats
• Pinch of salt

Stir until the mixture comes together. Here’s a pro tip: set aside one heaping cup for your crumbly topping.

Step 5: Form the Crust

Press the remaining oatmeal mixture firmly into the bottom of your prepared pan. Make sure it’s nice and even.

Step 6: Layer the Raspberry Goodness

Spread raspberry preserves across the entire crust. Aim for a smooth, even layer about 1/8 to 1/4 inch thick. This is where the magic happens!

Step 7: Create the Crumble Topping

Sprinkle the reserved oatmeal mixture over the raspberry layer. Want extra-chunky crumbles? Gently squeeze some mixture in your hand as you sprinkle.

Step 8: Bake to Perfection

Pop the pan in the oven and bake for 30 minutes. You’re looking for golden edges and a center that’s just set.

Step 9: Cool and Slice

Remove from the oven and let the bars cool on a wire rack for at least 2 hours.

Tips for Crispy Tops and Juicy Raspberry Filling

• Select Fresh Preserves: Choose high-quality raspberry preserves with real fruit chunks for maximum flavor and authentic berry taste.
• Create Chunky Crumble: Squeeze the oatmeal mixture between your fingers while sprinkling to develop larger, more textured crumble pieces on top.
• Control Jam Thickness: Spread preserves evenly but sparingly, aiming for a thin 1/8 to 1/4-inch layer to prevent soggy bars.
• Ensure Complete Cooling: Allow bars to cool completely for at least 2 hours, which helps them set and makes cutting clean, neat slices easier.
• Line Pan Perfectly: Use aluminum foil with nonstick spray for effortless removal and clean cutting of bars without sticking or breaking.

Storage Tips for Oatmeal Bars That Stay Fresh

Refrigerate: Store leftover bars in an airtight container in the refrigerator for up to 5 days. Place parchment paper between layers to prevent sticking and maintain their texture.

Freeze: Wrap individual bars tightly in plastic wrap, then place in a freezer-safe container. They’ll stay fresh for 2-3 months. Thaw overnight in the refrigerator before enjoying.

Reheat: Warm bars briefly in the microwave for 10-15 seconds or enjoy at room temperature. For a crisp texture, pop them in a preheated 325°F oven for 5-7 minutes before serving.

Great Additions to Serve with Raspberry Crumble Bars

• Pair with Creamy Vanilla Delight: Serve these bars alongside a scoop of smooth vanilla ice cream, letting the cold creaminess complement the warm, crumbly texture of the raspberry bars.
• Match with Bold Coffee Companion: Brew a rich, medium-roast coffee to balance the sweet-tart raspberry flavor, creating a perfect morning or afternoon treat that awakens your taste buds.
• Create a Tangy Tea Twist: Steep a cup of bright raspberry or Earl Grey tea to enhance the fruity notes of the dessert, offering a sophisticated and refreshing beverage pairing.
• Elevate with Whipped Cream Indulgence: Top the bars with a dollop of lightly sweetened whipped cream, adding a cloud-like softness that contrasts with the crumbly oatmeal base.

Variations That Bring New Life to a Classic Bar

• Berry Bliss Bars: Swap raspberry preserves with a mixed berry jam for a vibrant, multi-berry flavor profile that adds complexity and depth to the classic recipe.
• Nutty Oat Adventure: Incorporate chopped almonds or pecans into the crumble topping for extra crunch and a rich, toasted nutty undertone that complements the sweet base.
• Tropical Fruit Fusion: Replace raspberry preserves with passion fruit or mango jam to create a sunny, tropical-inspired version that brings a bright, exotic touch to the traditional bars.
• Spiced Comfort Crumble: Add ground cinnamon and a hint of nutmeg to the oatmeal mixture for a warm, comforting twist that enhances the overall richness of the dessert.
