How to Make Raspberry Bars with Oatmeal Crumble Topping
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line an 8-inch square pan with aluminum foil and spray it with cooking spray; set aside.
Step 2: Melt the Butter
In a large microwave-safe bowl, add the butter. Heat on high power until melted, about 1 minute.
Step 3: Combine Ingredients
Add the granulated sugar, light brown sugar, and vanilla extract. Whisk until combined.
Step 4: Mix Dry Ingredients
To the bowl, add the all-purpose flour, old-fashioned whole-rolled oats, and optional salt. Stir until combined. The mixture should have larger crumble pieces along with sandier bits.
Step 5: Set Aside Crumble Mixture
Set aside one heaping cup of the mixture to be used later as the topping.
Step 6: Prepare the Base
Transfer the remaining mixture into your prepared pan. Use a spatula or your fingers to hard-pack it into an even, smooth crust.
Step 7: Add Raspberry Preserves
Spread the raspberry preserves evenly over the crust. Ensure complete coverage; aim for about 1/8-inch to 1/4-inch thickness.
Step 8: Sprinkle Crumble Topping
Sprinkle the reserved heaping cup of crumble mixture evenly on top. Squeeze it in your palm first to encourage larger crumble pieces if desired.
Step 9: Bake
Bake for about 30 to 32 minutes or until edges are set and center is lightly golden brown. Allow cooling on a wire rack for at least two hours before slicing and serving.

Common Mistakes to Avoid
Many people encounter challenges when making Raspberry Bars with Oatmeal Crumble Topping. Here are some common mistakes to steer clear of:

- Not measuring ingredients accurately: Inaccurate measurements can alter the texture and flavor. Use precise measuring cups and spoons for best results.
- Skipping the cooling step: Cutting the bars before they cool can result in messy pieces. Allow them to cool completely before slicing for clean cuts.

- Ignoring ingredient quality: Low-quality raspberry preserves can affect taste. Choose a good brand or homemade preserves for enhanced flavor.
