Raspberry Oatmeal Crumble Bars Ingredients
For the Crust
• Butter – Provides richness and moisture; can substitute with a vegan spread for a dairy-free option.
• Granulated Sugar – Sweetness base for the crust and crumble; can use a sugar substitute or less for reduced sweetness.
• Light Brown Sugar – Adds depth of flavor and moisture; replace with more granulated sugar if necessary.
• Vanilla Extract – Enhances flavor; almond extract can be used for a different twist.
• All-Purpose Flour – Forms the structure of the crust; substitute with gluten-free flour for a gluten-free option.
• Old-Fashioned Rolled Oats – Adds chewiness and texture; do not substitute with quick oats as they negatively impact texture.
• Salt – Balances sweetness; omit if using salted butter.
For the Filling
• Raspberry Preserves – The star of the show, delivering that tangy flavor; feel free to replace with other fruit preserves or fresh fruit such as blueberries or strawberries.
For the Topping

Step‑by‑Step Instructions for Raspberry Oatmeal Crumble Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare an 8×8-inch baking pan by lining it with aluminum foil for easy removal or spraying it generously with cooking spray. This step ensures that your Raspberry Oatmeal Crumble Bars will pop out easily once they are baked and cooled.
Step 2: Melt the Butter
In a microwave-safe bowl, melt ½ cup of butter by heating it in the microwave for about 1 minute. Keep a close eye on it to prevent splattering. Once melted, take it out and allow it to cool slightly. The butter should be warm but not bubbling, making it perfect for mixing with the sugars.
Step 3: Mix in the Sugars and Vanilla
Add ½ cup of granulated sugar, ½ cup of light brown sugar, and 1 teaspoon of vanilla extract to the melted butter. Whisk these ingredients together until fully combined and smooth, creating a sweet and fragrant mixture. The sugars will dissolve into the butter, giving a nice glossy appearance.
Step 4: Combine Dry Ingredients
Next, add 1 cup of all-purpose flour, 1 cup of old-fashioned rolled oats, and a pinch of salt to the wet mixture. Stir these dry ingredients in until just combined. Reserve 1 heaping cup of this mixture for the crumble topping, and ensure that the remaining dough is well blended and cohesive to form the base of your Raspberry Oatmeal Crumble Bars.
Step 5: Form the Crust
Take the remaining mixture and evenly press it into the bottom of your prepared pan. Use a spatula or your fingers to spread it out, creating a solid crust layer about ¼-inch thick. This forms the essential base of your Raspberry Oatmeal Crumble Bars, giving them structure and a delightful chewiness.
Step 6: Spread the Raspberry Preserves
Now, layer the yummy raspberry preserves over the pressed crust. Aim for an even spread that’s about ⅛ to ¼ inch thick, coating every corner of the crust. This luscious raspberry layer provides a burst of flavor and moisture, making your bars irresistibly delicious.
Step 7: Add the Crumble Topping
Sprinkle the reserved crumble mixture over the raspberry preserves. Don’t worry about making it perfect; a slightly uneven layer adds texture. Press it down gently with your fingertips to ensure it adheres to the preserves, enhancing the crunchy topping that complements the soft filling of your Raspberry Oatmeal Crumble Bars.
Step 8: Bake to Perfection
Place the pan in your preheated oven and bake for 30 minutes, checking for a golden-brown crust and set edges. You’ll know they are ready when the top is fragrant and lightly browned. Allow the bars to cool in the pan at room temperature for at least 2 hours before slicing, as this helps them firm up for easy handling.
How to Store and Freeze Raspberry Oatmeal Crumble Bars
Room Temperature: Store the bars in an airtight container at room temperature for up to 3 days to maintain freshness and flavor.
Fridge: For longer storage, refrigerate the bars in an airtight container for up to 1 week, allowing the flavors to deepen while keeping the crust firm.
Freezer: These Raspberry Oatmeal Crumble Bars freeze beautifully! Wrap them tightly in plastic wrap or aluminum foil, then store in an airtight container for up to 2 months.
Reheating: To enjoy your bars warm, simply microwave for 10-15 seconds or bake in a preheated oven at 350°F for 5-10 minutes until heated through.

Tips for the Best Raspberry Oatmeal Crumble Bars

Raspberry Oatmeal Crumble Bars Recipe FAQs
What ripeness of raspberries should I use for the preserves?
Absolutely! When selecting raspberries for your Raspberry Oatmeal Crumble Bars, look for firm, plump berries that have a vibrant red color. Avoid any with dark spots or that feel mushy, as this can affect the texture and flavor of your filling. If opting for fresh fruit, ensure they’re sweet and ripe, as under-ripe fruit could lead to a less enjoyable tartness.
How should I store the Raspberry Oatmeal Crumble Bars?
Store the bars in an airtight container at room temperature for up to 3 days. If you want to prolong their freshness, refrigerate them for up to a week. They can also be kept in the freezer for up to 2 months! Wrap them tightly in plastic wrap or aluminum foil and place them in a freezer-safe container to prevent freezer burn.
Can I freeze Raspberry Oatmeal Crumble Bars?
Yes, you can! To properly freeze them, first allow the bars to cool completely, then wrap each bar tightly in plastic wrap. Place the wrapped bars into a freezer-safe bag or container, making sure to label it. When you’re ready to enjoy a bar, simply remove it from the freezer and let it thaw at room temperature, or heat it in the microwave for about 15-20 seconds.
What should I do if the bars crumble when I cut them?
Very! If your Raspberry Oatmeal Crumble Bars are crumbling apart while slicing, it might be due to not cooling them completely before cutting. Allow them to cool in the pan for at least 2 hours. If using fresh fruit, make sure the filling isn’t too runny—allow for excess moisture to evaporate. For future batches, you can also try adding a bit more flour to the crust mixture to help with structure.
Are there any allergy considerations with this recipe?
When preparing the Raspberry Oatmeal Crumble Bars, keep in mind potential allergens. The recipe contains gluten from the all-purpose flour and oats, and dairy from the butter. For a gluten-free option, use gluten-free flour and certified gluten-free oats. Dairy-free spreads can substitute the butter if needed. Always check the labels of your ingredients to ensure they meet dietary needs, especially if serving guests with allergies.
Can I adapt this recipe for different fruits?
The more the merrier! Feel free to experiment with various fruit preserves or fresh fruits like apricots, peaches, or blueberries! Just remember to adjust the sugar levels when using fresh fruit, as they tend to be less sweet than preserves. Using a combination of fruits can also yield a delightful flavor profile that enhances the overall taste of your Raspberry Oatmeal Crumble Bars.
