Kitchen Tools You’ll Need
- Mixing bowls
- Measuring cups and spoons
- 9×9-inch baking pan
- Parchment paper (for easy removal)
- spatula or wooden spoon
Ingredients
- 1 cup all-purpose flour (structure)
- 1 cup old-fashioned rolled oats (texture and chew)
- ½ cup unsalted butter, cold and diced (or grated) (richness and moisture)
- ⅓ cup granulated sugar (sweetness)
- ⅓ cup brown sugar, packed (depth of flavor)
- 1 teaspoon baking powder (leavening)
- ¼ teaspoon salt (enhances flavor)
- ½ teaspoon cinnamon (warmth)
- 2 cups fresh strawberries, hulled and sliced (or thawed frozen strawberries, well-drained) (freshness and moisture)
- 2 tablespoons granulated sugar (sweetness for filling)
- 1 tablespoon brown sugar (additional flavor)
- 2 teaspoons lemon juice (brightness)
- 1 teaspoon lemon zest (aromatic edge)
- ¼ cup strawberry jam (added moisture and sweetness)
- 1 tablespoon cornstarch (thickens filling; add 1 extra teaspoon if using frozen strawberries)
How to Make Easy Strawberry Oatmeal Bars
Step 1. Start by preheating your oven to 350°F. Prepare your baking pan by lining it with parchment paper, allowing some overhang to make lifting the bars easier later. This step provides a non-stick surface which is helpful when you’re ready to cut the bars.
Step 2. In a mixing bowl, combine the all-purpose flour, rolled oats, granulated sugar, brown sugar, baking powder, salt, and cinnamon. Stir these dry ingredients until well mixed, ensuring that the sugars and spices are evenly distributed throughout the flour and oats.
Step 3. Next, add the cold, diced or grated unsalted butter to the dry ingredients. Using a fork or your fingers, work the butter into the mixture until it resembles coarse crumbs. This process is essential for creating that necessary crumble texture, so pay attention to prevent the butter from fully melting into the mixture.
Step 4. Once you have your crumb mixture ready, reserve about one cup of it to sprinkle on top later. Pour the remaining mixture into the lined baking pan, pressing it firmly into an even layer across the bottom. Make sure it packs down well to form a solid base for the bars.
Step 5. In a separate bowl, prepare the strawberry filling by combining the sliced fresh strawberries (or thawed and well-drained frozen strawberries) with granulated sugar, brown sugar, lemon juice, lemon zest, strawberry jam, and cornstarch. Mix gently to coat the strawberries in the sweet mixture and dissolve the cornstarch, which will help thicken the filling as it bakes.
Step 6. Spread the strawberry mixture evenly over the crust in the baking pan. Layering the strawberries on top of the crust allows their sweetness to infuse into the oats below as they bake.
Step 7. Finally, sprinkle the reserved crumble mixture over the strawberry layer. This creates a lovely topping that will bake to a golden-brown color, providing a pleasant contrast to the soft fruit filling beneath.
Step 8. Bake in your preheated oven for about 30 to 35 minutes, or until the top is lightly golden and you can see the filling bubbling up around the edges. This visual cue indicates that the bars are done and will help achieve that perfect crumble texture.

Pro Tips for Best Results
- Make sure your butter is cold to achieve a flaky crumb topping.
- When mixing the crumble, avoid overworking the butter to ensure a crumbly texture.
- Use fresh strawberries if possible; if using frozen, ensure they are well-drained to prevent excess moisture.
- Allow the bars to cool completely before cutting to maintain their shape.
- Adjust the lemon juice and zest to taste for a more or less citrusy flavor.
- Serve with a dollop of whipped cream or a scoop of ice cream for a treat.
Common Mistakes to Avoid
- Not allowing the bars to cool completely: Cutting them too soon can cause them to fall apart. Letting them cool allows the filling to set.
- Using warm or melted butter: This can create a soggy bottom crust. Cold butter is key for the right crumble texture.
- Overmixing the crumble: Mixing too much can lead to a dense topping instead of a light, crumbly finish.
- Skipping the cornstarch: Failing to include cornstarch can result in a runny filling. It’s essential for helping the filling hold together.
- Not monitoring baking time: Keeping an eye on your bars as they bake can help prevent burning and achieve the desired golden color.
- Forgetting to line the pan: Not lining with parchment can make removal difficult. It’s a simple step that makes all the difference.
Variations & Substitutions
If you want to switch things up, consider replacing strawberries with blueberries or raspberries for a different fruit flavor. You can also add a handful of chopped nuts to the crumble mixture for added texture. If you’re looking for an extra layer of sweetness, consider drizzling a simple glaze over the bars once they’ve cooled. Just mix powdered sugar with a little milk or water until you reach your desired consistency.
Storage & Reheating
These bars can be stored at room temperature in an airtight container for up to three days. If you want to keep them longer, consider refrigerating them, where they can last for about a week. They also freeze well; wrap them individually or layer them in an airtight container separated by parchment paper, and they can last for up to three months. To reheat, simply warm in the oven at a low temperature to maintain their texture, rather than using the microwave.
