- Oatmeal: the recipe calls for 1-minute instant oatmeal.
- Sugar: use golden brown sugar to make the crumble or replace it with granulated sugar. To make the recipe refined sugar free, replace regular sugar with coconut sugar.
- Flour: use all-purpose flour to make this recipe. To make it gluten-free, replace flour with a gluten-free 1:1 flour blend.
- Butter: the recipe calls for unsalted butter right from the refrigerator. It has to be cold to make the crumble.
- Strawberry preserves: use fruit preserves or strawberry jam. If it is thick enough to spread, bring it to the microwave for 1 minute to soften.
- Fresh strawberries: seasonal sweet fresh strawberries are the best to make these crumb bars. Travel to your local strawberry farm for strawberry picking or purchase ripe berries in a grocery store or a farmers market.
You can replace them with blueberries, raspberries, blackberries, or stone fruit.
- Corn starch is used to toss fresh red berries to thicken their juice while baking. Replace it with tapioca flour or arrowroot starch if desired.
How to make strawberry crumble bars
Step 1. Prepare for baking. Heat oven to 375 degrees F/190 degrees C. Butter or spray with cooking spray 7 x 7-inch/18 x 18-cm square baking pan. Line it with parchment paper, hanging it over two sides.
Step 2. Make the crumble. In a large bowl, combine flour, oatmeal, and brown sugar, and mix. Add cold butter to the dry ingredients.
Mix with hands, a fork, or a pastry blender until the crumbly texture sticks under the pressure of fingers (photo 1).
Press two-thirds of the crumble mixture into the bottom of the prepared pan (photo 2).
Spread strawberry preserves in an even layer over the buttery crust (photo 3).
Step 3. Make the sweet strawberry filling. In a small bowl, combine strawberries cut into four lengthwise, granulated white sugar, and cornflour (photo 4).
Distribute berries into the fresh strawberry layer (photo 5). Using your hands, cover with the remaining dough (photo 6).
Step 4. Bake and serve. Bake for about 50 minutes or until the top is golden brown (photo 7). Remove from the oven and let cool for 10 to 20 minutes in the pan.
Lift the crumble out of the mold using parchment paper. Let cool completely. Using a sharp knife, cut into squares (photo 8). Serve them on their own or accompany a scoop of ice cream.
- To cut strawberries, use a strawberry slicer if desired.
- Make sure to use very cold butter to get the correct consistency of the crumble.
- Don’t overmix the crumbly topping. Once you get the sandy mixture, please, stop. Read more about how to make the perfect streusel topping.
- Be sure to line your baking dish with parchment paper hanging over at least two sides. This will facilitate the removal of strawberry bars after baking.
- Let your bars cool completely before slicing for at least an hour.
This recipe is a foolproof one that is perfect as it is. But you can play with the thickness of the crumble, different fruits, and add-ins.
- Instead of dividing the crumble mixture into ⅓ and ⅔, make the bottom layer equal to the top crust layer. Press half of the crumb mixture to the bottom of the pan. Then cover the strawberry layer with the remaining crumble.
- To bring even more crunchiness to the bars, you can add ¼ cup of chopped nuts into the crumb mixture.
- For a citrus flavor, add some lemon zest to the strawberry filling.
- Finally, replace juicy strawberries with other fruits: blueberries, raspberries, blackberries, and stone fruit.
There is no need to add sugar or cornflour with the use of whole fruit. But add an additional teaspoon of cornstarch with stone fruit cut into slices.
Storing and freezing
Store bars in an airtight container at room temperature for up to 2 days, or keep them in the refrigerator for up to 5 days.
Can you freeze strawberry crumble bars? You can freeze these bars for up to 3 months. Cover cooled bars in plastic wrap or place them in a freezer-safe container and freeze.
To thaw, bring them to the refrigerator overnight. Serve bars at room temperature.
You can make this recipe with frozen strawberries instead of fresh ones. Let them thaw out, and drain well before chopping and making the filling.
