For the Base and Topping
- 1/2 cup unsalted butter, melted
- 1/2 cup granulated sugar
- 1/4 cup light brown sugar, packed

- 3/4 cup old-fashioned whole-rolled oats
- Pinch salt, optional and to taste
For the Filling
- About 12 ounces raspberry preserves, with or without seeds
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 fully melted, about 1 minute.
Step 3: Mix in Sugars and Vanilla
Add the granulated sugar, light brown sugar, and vanilla extract to the melted butter. Whisk together until well combined.
Step 4: Combine Dry Ingredients
Add the all-purpose flour, rolled oats, and optional salt into the mixture. Stir until combined; you should have larger crumble pieces along with some finer bits.
Step 5: Reserve Crumble Mixture
Set aside one heaping cup of the mixture to use as a topping later.
Step 6: Form the Crust
Transfer the remaining mixture into your prepared pan. Use a spatula or your fingers to hard-pack it into an even layer that is smooth.
Step 7: Spread Raspberry Preserves
Evenly spread the raspberry preserves over the crust layer. 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 over the raspberry preserves. Squeeze the mixture in your palm before sprinkling to create bigger crumble pieces.
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 baked, place the pan 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 ensure you create the best Raspberry Bars with Oatmeal Crumble Topping, consider these simple tips for perfect results every time.
- Use room temperature ingredients: Allow butter and eggs to come to room temperature before mixing. This helps create a smoother batter, leading to better texture.
- Check your oven temperature: Use an oven thermometer if possible. An accurate temperature ensures even baking and prevents undercooked centers or burnt edges.
- Let them cool completely: Allow the bars to cool for at least 2 hours before slicing. This helps them set properly, making it easier to cut clean pieces.
- Experiment with preserves: Try different fruit preserves like strawberry or blueberry if you want to mix things up while keeping the same base recipe.
- Store correctly: Keep leftover bars in an airtight container at room temperature for up to 3 days or refrigerate them for longer freshness.

Common Mistakes to Avoid
When making Raspberry Bars with Oatmeal Crumble Topping, it’s easy to make a few common errors. Here are mistakes to watch out for:

- Not packing the crust firmly: A loose crust can crumble apart. Pack it down well with a spatula or your fingers for a sturdy base.
- Overbaking: Baking too long can dry out the bars. Keep an eye on them and remove them once they are lightly golden.
- Ignoring cooling time: Cutting too soon can result in messy bars. Allow them to cool for at least 2 hours before slicing.
- Using low-quality preserves: Poor-quality raspberry preserves may lack flavor. Choose high-quality preserves for better taste.
