Step‑by‑Step Instructions for Strawberry Oatmeal Crumble Bars
Step 1: Prepare the Crumble Base
In a large mixing bowl, combine 220 g of flour, 100 g of oats, 150 g of sugar, and 1 teaspoon of salt. Cut in 200 g of softened unsalted butter using a fork or pastry cutter until the mixture resembles coarse crumbs. This will be the crumble base for your Strawberry Oatmeal Crumble Bars. Set aside a small portion of the crumble mixture to top the bars later.
Step 2: Press the Crumble into the Pan
Preheat your oven to 180°C (350°F). Grease an 8x8-inch baking dish and press the majority of the crumble mixture evenly into the bottom. This will form a solid base for your bars. Bake in the preheated oven for 15-20 minutes, or until it's golden brown. Keep an eye on it, as you want a beautiful, toasted color.
Step 3: Prepare the Strawberry Filling
While the base is baking, wash and chop 400 g of fresh strawberries. In a small bowl, combine the chopped strawberries with 4 tablespoons of strawberry jam and 1 teaspoon of optional vanilla bean paste. Toss the mixture gently until the strawberries are well-coated. This sweet filling will add a burst of flavor to your Strawberry Oatmeal Crumble Bars.
Step 4: Assemble the Bars
Once the crumble base is out of the oven and slightly cooled, spread the strawberry mixture evenly over the top of the base. Make sure to distribute it well to ensure every bite of your Strawberry Oatmeal Crumble Bars is packed with fruity goodness.
Step 5: Top with Remaining Crumble
Sprinkle the reserved crumble mixture over the strawberry filling evenly, creating a nice, crunchy top layer. This crumble will bake together with the strawberries, forming a delicious topping for your bars.
Step 6: Bake Again
Return your dish to the oven and bake for an additional 20-25 minutes, or until the top is golden and crispy. You'll know it’s done when you see a delightful golden layer on top, inviting you to take a bite of those irresistible Strawberry Oatmeal Crumble Bars.
Step 7: Cool and Slice
Once baked, remove the dish from the oven and allow the bars to cool in the pan for at least 30 minutes. This cooling step is crucial as it helps the bars set properly. Once cool, slice them into squares and serve your delicious homemade treat.

Make Ahead Options
These Strawberry Oatmeal Crumble Bars are perfect for busy weeknights or when you need a quick dessert. You can prepare the crumble base up to 24 hours in advance; simply mix the ingredients and refrigerate them in an airtight container. Additionally, the strawberry filling can be prepped and stored in the fridge for up to 3 days – just toss the chopped strawberries with the jam and vanilla bean paste, and they’ll stay fresh and delicious. When you're ready to serve, simply press the crumble into the baking dish, layer the strawberry mixture, top it with crumble, and bake as directed for a homemade treat that's just as delightful!

Expert Tips for Strawberry Oatmeal Crumble Bars
Mind the Butter: Use softened unsalted butter for the crumble. Cold butter can create a dense texture instead of a light and crumbly base.
Even Strawberry Spread: Make sure to distribute the strawberry filling evenly over the base; this ensures every bite of your Strawberry Oatmeal Crumble Bars is just as delicious.
Cooling Time Matters: Allowing the bars to cool completely in the pan strengthens their structure, making them easier to slice and preventing them from falling apart.
Watch the Oven: Baking times can vary based on your oven; keep a close eye on the last few minutes to achieve that perfect golden-brown top without over-baking.
Customize the Flavor: Feel free to add your favorite nuts or spices to the crumble mixture for an extra layer of flavor that personalizes your Strawberry Oatmeal Crumble Bars!

Strawberry Oatmeal Crumble Bars Recipe FAQs
How do I choose ripe strawberries for the filling?
Absolutely! When selecting strawberries, look for those that are bright red and firm, with a sweet aroma. Avoid any with dark spots all over or that feel soft, as they are likely overripe. I personally love using local strawberries when they’re in season, as they’re often fresher and more flavorful.
What’s the best way to store leftover bars?
Very simple! To keep your Strawberry Oatmeal Crumble Bars fresh, store them in an airtight container at room temperature for up to 3 days. If you prefer them chilled, pop them in the fridge where they’ll last about a week. Just remember, the colder they are, the longer they’ll stay delicious!
Can I freeze Strawberry Oatmeal Crumble Bars?
Absolutely! To freeze your bars, first slice them into squares. Wrap each slice securely in plastic wrap, then place them in a freezer bag. These can be stored for up to 3 months. When you’re ready to enjoy them, just thaw in the fridge overnight or pop them in the microwave for about 15-20 seconds for a quick treat.
What if my crumble topping doesn’t turn out crunchy?
No worries! If your topping is too soft, it might be due to using cold butter or not baking it long enough. To prevent this, make sure your butter is softened and mixed well until crumbly. When baking, ensure the top is golden brown - this usually takes an additional 20-25 minutes. If they still seem soft after cooling, just bake them for a few more minutes next time!
Are Strawberry Oatmeal Crumble Bars safe for my pet?
Good question! While strawberries are generally safe for dogs in moderation, it's best to avoid giving your furry friends baked goods that contain sugar and butter. Always check with your veterinarian if you're unsure about sharing human food with your pets.
Can I substitute the flour for a gluten-free option?
Definitely! If you want to make gluten-free Strawberry Oatmeal Crumble Bars, try using a 1:1 gluten-free flour blend. Additionally, ensure your oats are certified gluten-free as some brands may be processed in facilities that handle wheat. This way, you'll still enjoy the taste without the gluten!
