Ingredients You’ll Need

These Raspberry Oat Crumble Bars rely on simple, wholesome ingredients that you probably already have in your kitchen. Each component plays its part: oats for chewiness, coconut oil for richness, and that jewel-bright preserved raspberry layer for pops of flavor and color.

• Coconut oil (melted): This gives the bars a moist, slightly tropical richness—plus, it helps make the crust and crumble just the right texture.
• All-purpose flour (or gluten-free substitute): The foundation of the base and topping; use your favorite gluten-free blend if needed.
• Quick oats: These create that signature hearty, crumbly bite and toast up beautifully in the oven.
• Maple syrup: Adds natural sweetness and brings a warm, almost caramel-like undertone to the bars.
• Coconut sugar (or granulated sugar): For just a touch of extra sweetness without overpowering the raspberry flavor.
• Baking powder: A pinch for lightness—helps everything bake up golden and not too dense.
• Salt: Don’t skip it! Salt balances out all the sweetness and lifts every other flavor.
• Raspberry preserves: The star of the show—look for a brand you love, or use homemade for a special touch.

Variations

The beauty of Raspberry Oat Crumble Bars is how easy they are to personalize! Don’t be afraid to swap ingredients and experiment—these bars are practically begging for your creative touch, whether you’re switching flavors or making them allergy-friendly.

• Switch up the fruit: Try strawberry, apricot, or blueberry preserves—any favorite jam or fruit spread will work a treat and create a whole new flavor profile.
• Make them vegan: Simply ensure your sugar and jam are vegan-friendly, and you’re all set—no animal products needed!
• Add nuts or seeds: Stir a handful of chopped almonds, walnuts, or sunflower seeds into the crumble for extra crunch and protein.
• Spice it up: Add a pinch of cinnamon, cardamom, or lemon zest to the crust for a deeper, more complex flavor.

How to Make Raspberry Oat Crumble Bars

Step 1: Prep your pan & set the scene

Preheat your oven to 350°F and give your 8×8 baking pan a quick spritz of non-stick spray. This might sound simple, but ensuring your bars come out easily (without any sticky mishaps!) makes all the difference in presentation and clean-up later on.

Step 2: Make the oat crumble mixture

In a large bowl, combine the melted coconut oil, flour, oats, maple syrup, coconut sugar, baking powder, and salt. Stir everything together until you have a thick, rough, crumbly dough. A spatula works fine, but using your hands helps make sure every oat gets coated and the mixture comes together perfectly.

Step 3: Form the crust

Press about two-thirds of your crumble mixture evenly into the base of your prepared pan. Take your time to get a layer that’s even and well-packed—all those hearty oats form a firm foundation for the jammy filling to rest on.

Step 4: Spread the raspberry preserves

Gently spread your raspberry preserves over the crust, taking care to leave about half an inch around the edges. This little margin keeps the jam from scorching against the pan, ensuring the center stays luscious and fruity.

Step 5: Finish with the crumble topping

Crumble the remaining oat mixture evenly over the raspberry layer, pressing just lightly to help the pieces stick. You want some clumps and texture here—that rustic, crumbly look is part of the charm!

Step 6: Bake and let cool

Pop your pan onto the center rack and bake for 25 to 30 minutes, until the top is lightly golden and the kitchen smells irresistible. Allow the bars to cool completely in the pan before slicing—this makes them much easier to cut into tidy squares (if you can resist digging in sooner!).

How to Serve Raspberry Oat Crumble Bars

Garnishes

A sprinkle of powdered sugar, a handful of fresh raspberries, or even a dollop of softly whipped cream can make these bars pop visually and in flavor. If you really want to go fancy, a drizzle of melted white chocolate on top adds a stunning finishing touch!

Side Dishes

Enjoy Raspberry Oat Crumble Bars alongside a warm cup of tea, a chilled glass of almond milk, or even with a scoop of creamy vanilla ice cream for dessert. They also pair beautifully with a simple yogurt parfait for a brunch that wows.

Creative Ways to Present

Cut the bars into bite-sized cubes for a sweet brunch buffet, or wrap individual squares in parchment and baker’s twine as sweet gifts. For an elegant twist at parties, stack the bars on a cake stand and tuck fresh berries or edible flowers between the layers for a colorful display.

Make Ahead and Storage

Storing Leftovers

Store any extra Raspberry Oat Crumble Bars in an airtight container at room temperature. They’ll stay wonderfully fresh for up to three days, but if your kitchen is very warm, you may want to keep them in the fridge for optimal texture.

Freezing

These bars freeze beautifully! Place sliced, fully cooled bars in a single layer on a sheet pan, freeze until solid, then transfer to a zip-top bag. They’ll keep their flavor and texture for up to two months—perfect for stashing away emergency treats.

Reheating

If you love your Raspberry Oat Crumble Bars warm, a quick 10-15 seconds in the microwave brings them right back to that “fresh from the oven” coziness. For a crispier texture, heat in a toaster oven for a few minutes until just warmed through.
