Strawberry Oatmeal Crumble Bars Step-by-Step Instructions
1. Crust and Crumble Topping:

- In a large, microwave-safe bowl, melt the butter, about 1 minute on high power.

- Transfer the remaining mixture to the prepared pan. Using a spatula or your hands, pack it down to create an even, smooth crust; set aside.
2. Strawberry Layer:
- In a medium-sized bowl, combine the chopped strawberries, sugar, lemon juice, and cornstarch. Toss gently to coat the strawberries evenly.
- Spread the strawberry mixture over the prepared crust in the pan, distributing it evenly.
3. Finishing Touches:
