Strawberry Oatmeal Crumble Bar Recipe with Simple Ingredients

Making Homemade Strawberry Oatmeal Bars does not require anything fancy. Most of the ingredients are pantry staples, and the strawberries bring everything to life with their natural sweetness.

2 cups old-fashioned rolled oats
1 1/2 cups all-purpose flour
3/4 cup brown sugar
1/2 teaspoon baking soda
1/4 teaspoon salt
3/4 cup unsalted butter, melted
2 cups fresh strawberries, chopped
1/3 cup granulated sugar
1 tablespoon lemon juice
2 teaspoons cornstarch

The base and crumble topping come from the same mixture, which makes this recipe even easier. Stir everything together until crumbly, then press part of it into the pan. The strawberry layer cooks down slightly while baking, creating that soft, jam-like texture that pairs perfectly with the oats.

How To Make Strawberry Crumble Bars Step by Step

If you are looking for Strawberry Oatmeal Bars Easy enough for a weeknight bake, this method keeps things simple and forgiving.

Pour in melted butter and stir until crumbly.
Press about two-thirds of the mixture into the pan to form the base.
Combine strawberries, sugar, lemon juice, and cornstarch in another bowl.
