A Cozy Bakery Style Treat

These raspberry oatmeal crumble bars taste like something you’d find in a cozy little bakery. The buttery oat mixture turns golden in the oven and creates the perfect mix of texture and flavor.

I love how simple this recipe is to make because the same oatmeal dough becomes both the crust and the crumble topping. The hint of almond extract gives the bars that extra bakery-style flavor that makes people stop after the first bite and ask for the recipe.

Let’s Talk Ingredients

Unsalted Butter-Use softened room temperature butter for easy mixing.

Brown Sugar-Gives these raspberry oat bars a warm caramel flavor and helps keep the bars tender.

All-Purpose Flour-Just enough to gives some structure without taking away from the granola like crumble topping.

Oatmeal-Old fashioned rolled oats work best, but you can use quick cooking oats in a pinch.

Baking Soda-A small amount of baking soda helps lighten the crumble mixture.

Salt-Just a pinch of salt balances the sweetness of the raspberry preserves.

Almond Extract-Gives these raspberry crumb bars their signature bakery-style flavor.

Raspberry Preserves-No need for fresh raspberries here. Sweet raspberry jam give these bars a freshly baked fruit flavor with almost no prep work.

Substitutions

Add fresh raspberries on top of the jam layer before adding the crumb topping.
Replace almond extract with vanilla extract for a more classic flavor.

Tools You’ll Need

8x8 baking tray or baking pan

How to Make Raspberry Oatmeal Crumble Bars

Prepare the Pan

Preheat your oven to 350 degrees F. Line an 8x8 baking tray with parchment paper, leaving extra parchment hanging over the sides for easy removal later.

Make the Crumble Mixture

In a large bowl, cream together the softened unsalted butter, almond extract and brown sugar until combined.

Add the flour, old-fashioned oats, baking soda,and salt. Mix until a soft crumbly dough forms.

Form the Bottom Layer

Reserve about 1 cup of the mixture for the crumb topping.

Press the remaining crumb topping firmly into the bottom of the prepared pan to create the buttery oatmeal crust.

Add the Raspberry Filling

Spread the raspberry preserves evenly over the crust. Make sure to spread the jam all the way to the edges so every bite has plenty of raspberry filling.

Add the Crumble Topping

Sprinkle the remaining crumble mixture evenly over the top of the jam layer.

Don't press the topping down. Keeping it loose helps create a nice crumbly texture.

Bake

Bake for 25-30 minutes until the crumb topping is lightly golden brown and the top of the jam is bubbling slightly around the edges.

Let the bars cool completely in the pan before lifting them out with the parchment paper.

Allyson’s Tips

Use an 8x8 pan lined with parchment paper, leaving enough parchment hanging over the edges so you can easily lift the bars out after baking.

Let the bars cool in the pan for 15 minutes on the counter. Then use the parchment paper to lift them out of the pan and transfer them to the refrigerator to chill for 45 minutes before slicing. This helps the bars set properly and gives you cleaner slices.

Storage & Make-Ahead Tips

Store the raspberry bars in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate the bars for up to 1 week.
Freeze the bars in a freezer-safe container with parchment paper between layers.
