For the Crust and Topping

1/2 cup unsalted butter, melted
1/2 cup granulated sugar
1/4 cup light brown sugar, packed

1 cup all-purpose flour
3/4 cup old-fashioned whole-rolled oats
Pinch salt, optional and to taste

For the Filling

How to Make Raspberry Bars with Oatmeal Crumble Topping

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line an 8-inch square pan with aluminum foil and lightly spray it with cooking spray. Set it aside.

Step 2: Melt the Butter

In a large microwave-safe bowl, add the melted butter. Heat it on high power until fully melted, about 1 minute.

Step 3: Combine Sugars and Vanilla

Add the granulated sugar, light brown sugar, and vanilla extract to the melted butter. Whisk them together until combined.

Step 4: Add Dry Ingredients

Add the all-purpose flour, rolled oats, and optional salt. Stir until combined. You will have some larger crumble pieces along with sandier bits.

Step 5: Reserve Crumble Topping

Set aside one heaping cup of this mixture; this will be used later as the crumble topping.

Step 6: Form the Base Layer

Transfer the remaining mixture into your prepared pan. Use a spatula or your fingers to hard-pack it into an even layer across the bottom.

Step 7: Spread Raspberry Preserves

Spread the raspberry preserves evenly over the crust layer. Ensure complete coverage; it should be about 1/8-inch to 1/4-inch thick.

Step 8: Add Crumble Topping

Sprinkle the reserved heaping cup of crumble mixture over the raspberry preserves. Squeeze it in your palm to create larger crumble pieces if desired.

Step 9: Bake Your Bars

Bake in preheated oven for about 30 to 32 minutes, or until edges are set and center is lightly golden brown. Let cool on a wire rack for at least two hours before slicing into bars.

Now you have delicious Raspberry Bars with Oatmeal Crumble Topping ready to enjoy!
