Ingredients for Strawberry Oatmeal Crumble Bars
To make these delightful bars, you’ll need the following ingredients:
- Butter: Adds richness and moisture to the crumble and crust.
- Flour: Provides structure and binds the ingredients together.
- Old-fashioned oats: Give the bars their signature chewiness and texture.
- Granulated sugar: Sweetens the crust and topping.
- Light brown sugar: Adds a hint of molasses flavor to the crust.
- Salt: Enhances the flavor of the other ingredients.
- Fresh strawberries: The star ingredient that gives the bars their juicy and tart sweetness.
- Lemon juice: Helps balance the sweetness and enhances the flavor of the strawberries.
- Cornstarch: Thickens the strawberry filling and helps it set.
Alternative Ingredient Suggestions
If you’re missing some of these ingredients or have dietary preferences, here are a few substitutions:
- Butter: Use a plant-based butter or coconut oil for a dairy-free version.
- Flour: Swap out all-purpose flour for gluten-free flour if you’re following a gluten-free diet.
- Old-fashioned oats: Quick oats can work in a pinch, but they will alter the texture slightly, so it’s best to stick with old-fashioned oats.
- Sugar: For a healthier option, you can replace the granulated sugar with coconut sugar or honey.
Step-by-Step Instructions for Strawberry Oatmeal Crumble Bars
Follow these simple steps to make your own batch of Strawberry Oatmeal Crumble Bars:
- Preheat the Oven: Preheat your oven to 350°F. Line an 8-inch square pan with aluminum foil and spray it with cooking spray to prevent sticking.
- Make the Crumble Topping: In a large, microwave-safe bowl, melt the butter. Add the flour, oats, granulated sugar, brown sugar, and salt. Stir until combined, leaving some larger clumps of the mixture.
- Prepare the Crust: Take about 1 cup of the crumble mixture and set it aside. Press the remaining mixture into the prepared pan, packing it down firmly to form an even crust.
- Prepare the Strawberry Filling: In a mixing bowl, combine the chopped strawberries, granulated sugar, lemon juice, and cornstarch. Stir to coat the strawberries evenly, and then pour this mixture over the crust in the pan.
- Top the Bars: Sprinkle the reserved crumble mixture over the strawberry filling. Gently press the mixture in your hands to form larger crumble pieces for a beautiful topping.
- Bake: Bake for about 50 minutes, or until the edges are golden and the center is set. The topping should be pale golden and the strawberry filling should be bubbly around the edges.
- Cool and Serve: Allow the bars to cool for at least an hour before slicing them into squares. If you slice them while still warm, they may fall apart.

Tips & Tricks for Perfect Strawberry Oatmeal Crumble Bars
- Don’t Overmix the Dough: For the best texture, avoid overmixing the crumble mixture. It should be just combined with some larger chunks to create a nice, rustic crumble topping.
- Watch the Baking Time: Keep an eye on the bars while baking. If your strawberries release a lot of juice, the bars may take a little longer to bake.
- Let Them Cool: Patience is key! Allow the bars to cool completely before slicing them to ensure they set properly.
Pairing Ideas and Variations
These Strawberry Oatmeal Crumble Bars are great on their own, but you can enhance the experience with a few pairing ideas:
- Ice Cream: Serve them warm with a scoop of vanilla ice cream or whipped cream for a decadent dessert.
- Fruit Variations: Try swapping the strawberries for other berries like blueberries or raspberries for a different twist on this classic recipe.
- Make-Ahead: These bars keep well in an airtight container at room temperature for up to a week, in the fridge for 10 days, or even in the freezer for up to 6 months. They make an excellent grab-and-go snack or dessert for busy days.
