Ingredients Notes
Gathering fresh strawberries is key to bringing out the full flavor in this recipe. If strawberries are out of season, feel free to use frozen ones; just make sure to thaw and drain them before using. Oats play a crucial role, providing that coveted crumbly texture. For a gluten-free option, use certified gluten-free oats. Finally, consider adding a pinch of cinnamon for a spicy undertone.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C) and lightly grease an 8-inch square baking pan. Set it aside while you prepare the crumble.
Step 2
In a medium bowl, combine oats, flour, and brown sugar. Use your fingers or a pastry cutter to work in the butter until the mixture resembles coarse crumbs.
Step 3
Press half of the crumble mixture firmly into the prepared pan to form a solid base. This will ensure the bars hold together after baking.

Step 4
Spread the chopped strawberries evenly over the base layer. Sprinkle the remaining crumble mixture on top, ensuring even coverage.
Step 5
Bake for 30-35 minutes until the top is golden brown. Allow it to cool completely in the pan before slicing into bars.
Storage Options
These bars store wonderfully in an airtight container at room temperature for up to three days. If you need to store them longer, refrigerate for up to a week. For even longer storage, freeze the bars in a single layer, then place into a zip-lock bag or container for up to two months. Thaw in the fridge and reheat in the oven for a few minutes to regain their crispness.
Variations & Substitutions
Substitute the strawberries with blueberries or raspberries for a different berry twist. For a nutty flavor, add chopped almonds or walnuts to the crumble mix. For a vegan version, replace the butter with coconut oil, and use a flax egg in place of a regular egg to bind the crumble.
Serving Suggestions
This dish is perfect for weekend brunches or afternoon tea gatherings. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for dessert. For a morning treat, enjoy them with a hot cup of coffee or tea.
Frequently Asked Questions
Can I use other types of fruits? Absolutely. While strawberries are sensational, you can mix in or replace them with other berries or even stone fruits like peaches or plums for a seasonal variety.
How do I prevent the bars from crumbling apart? Make sure to pack the base layer tightly and allow the bars to cool completely before cutting. Using cold butter and not overmixing the crumble ingredients also helps maintain structure.
Is it possible to make this recipe sugar-free? You can substitute sugar with a natural sweetener like honey or maple syrup, adjusting amounts to taste. Keep in mind this may alter the texture slightly, depending on the chosen alternative.
