I recently whipped up a batch of these delightful Strawberry Oatmeal Bars that combine crisp oats, silky butter, and fresh strawberries with a touch of lemon juice. The mix of all-purpose flour, brown and granulated sugar creates a delectable contrast that leaves me excited for every bite and endless delight.
I recently came across an idea that really blew my mind and I spent the weekend experimenting with it. These Strawberry Oatmeal Crumble Bars are my new go-to treat that strike a cool balance between fruity fun and a crunchy finish.
I mixed 1 cup all-purpose flour with 1/3 cup granulated sugar and 1/2 cup unsalted butter, melted just right, to create the base. Then, I layered on fresh strawberries, about 4 cups, tossed with 1 tablespoon lemon juice, a little extra sugar, and a touch of cornstarch to thicken the filling.
To top it off, I combined 1 cup old fashioned oats, a bit more all-purpose flour, light brown sugar, salt, and cold cubed butter to create a crumble that bakes into perfection. This recipe ties into my love for easy, fresh strawberry desserts and even finds itself among my favorite fruit recipes when I need that delightful twist.
Enjoy giving it a try and tweaking it your way.

Ingredients
- Fresh Strawberries: They provides natural sweetness, juicy flavor, fiber, and vitamins for extra energy.
- Old fashioned Oats: They offer hearty fiber and complex carbs while adding a chewy texture.
- All-purpose Flour: It forms the base, helps make crumbly bars with its starchy carbohydrate content.
- Light Brown Sugar: Adds sweet moisture and subtle molasses flavor for a rich, deep taste.
- Unsalted Butter: Provides a creamy texture and lip smacking flavor without extra salt.
- Lemon Juice: Gives a little tangy kick to balance out the fruity sweetness nicely.
- Cornstarch: Helps thicken the strawberry filling creating a perfect, luscious consistency.
- Granulated Sugar (for filling): Sweetens the strawberries, intensifies flavor and enhances color.

How to Make this
1. Preheat your oven to 350°F and grease an 8×8 inch pan.

FAQ
Strawberry Oatmeal Crumble Bars Recipe Substitutions and Variations
- You can swap the all-purpose flour with whole wheat flour for a nuttier taste. Use about 75% all-purpose and 25% whole wheat to keep the texture balanced.
- If you wanna avoid granulated sugar, try using maple syrup instead, but reduce the amount a bit since it’s sweeter.
- Instead of melted unsalted butter, you can use an equal amount of melted coconut oil. It adds a slight coconut flavor that works pretty well with strawberries.
- If you’re short on fresh strawberries, feel free to use frozen ones. Just thaw them and drain off any extra juice before using.
- You can choose quick oats in place of old fashioned oats. The bars may turn out a bit different, but they’ll still be delicious.
Pro Tips
1. Make sure you press the bottom crust really down tight into the pan so it sticks to the bars after you bake it.
2. When mixing the strawberry filling, stir it well to avoid clumps of cornstarch that might mess up the texture later.
3. Use your fingers or a pastry cutter to blend the cold butter into the crumble topping just enough; you dont want it too smooth or too chunky.
4. Let the bars cool completely before you cut them so they firm up which will help keep them from falling apart.
