Ingredients:
– 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)

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 spray it with cooking spray; set aside.
Step 2: Melt the Butter
In a large, microwave-safe bowl, add the melted butter. Heat it on high power until completely melted, about 1 minute.
Step 3: Combine Wet Ingredients
Add the granulated sugar, light brown sugar, and vanilla extract to the melted butter. Whisk them together until well combined.
Step 4: Mix Dry Ingredients
Stir in the all-purpose flour, rolled oats, and optional salt into the mixture. The mixture should have both larger crumble pieces and finer bits.
Step 5: Reserve Crumble Topping
Set aside one heaping cup of this mixture to use later as crumble topping.
Step 6: Create the Base Layer
Transfer the remaining mixture into your prepared pan. Using a spatula or your fingers, firmly pack it down to create an even crust.
Step 7: Spread Raspberry Preserves
Evenly spread about 12 ounces of raspberry preserves over the crust. Ensure complete coverage; aim for a thickness of about 1/8 inch to 1/4 inch.
Step 8: Add Crumble Topping
Sprinkle the reserved heaping cup of crumble mixture over the raspberry preserves. Squeeze it in your palm first for larger pieces if desired.
Step 9: Bake
Bake in the preheated oven for about 30 to 32 minutes or until edges are set and center is lightly golden brown. Once done, place on a wire rack to cool for at least two hours before slicing into bars.

How to Perfect Raspberry Bars with Oatmeal Crumble Topping
To achieve the best results when making Raspberry Bars, consider these helpful tips for perfection in every bite.
- Use cold butter: Start with cold, unsalted butter for a flakier crumble topping that holds together well.
- Don’t overmix: Mix just until combined to keep the texture crumbly rather than dense.
- Adjust sweetness: Taste your raspberry preserves before using; if they are too sweet, consider reducing the amount of sugar in your crust.
- Let them cool completely: Allow bars to cool fully before slicing; this helps them set nicely and makes cutting easier.
- Store properly: Keep any leftovers in an airtight container at room temperature for up to three days for maximum freshness.
Best Side Dishes for Raspberry Bars with Oatmeal Crumble Topping

-

Common Mistakes to Avoid
Baking Raspberry Bars with Oatmeal Crumble Topping can be simple, but a few common mistakes can lead to less-than-perfect results. Here are some tips to help you avoid them:
- Not measuring ingredients accurately: Always use a kitchen scale or measuring cups to ensure precise measurements for the best results.
- Using cold butter: Melt your butter completely before mixing. Cold butter can lead to uneven texture in the crumble topping.
- Skipping the cooling time: Allow the bars to cool for at least 2 hours before slicing. This helps them set properly and makes cutting easier.
- Overbaking the bars: Keep an eye on your baking time. Remove them from the oven when they are lightly golden brown around the edges.
- Ignoring ingredient substitutions: If you’re out of an ingredient, find a suitable alternative that maintains flavor and texture. For example, use a different fruit preserve if you don’t have raspberry.
