How Do You Make Strawberry Oatmeal Crumble Bars Step-by-Step?
Follow these simple steps to create your very own Strawberry Oatmeal Crumble Bars. Don’t rush through it; take your time for the best results!
Step 1
Preheat your oven to 350°F and line an 8-inch square pan with aluminum foil. Don’t forget to spray it with cooking spray to avoid sticking later on.
Step 2
In a large microwave-safe bowl, melt the unsalted butter, which should take about 1 minute on high power.
Step 3
Add the flour, oats, both sugars, and salt into the bowl with the melted butter. Mix well until it resembles a dry and sandy mixture with larger crumbs here and there.
Step 4
Set aside about one heaping cup of the mixture for the crumble topping later. Press the remainder firmly into the prepared pan to create an even crust.
Step 5
For the strawberry layer, combine coarsely chopped strawberries, sugar, lemon juice, and cornstarch in a separate bowl. Stir well to coat the strawberries.
Step 6
Spread the strawberry mixture evenly over the crust you just made. Lastly, sprinkle the reserved crumble mixture on top of the strawberries.
Step 7
Bake in the preheated oven for about 30 minutes or until the top is golden brown and the strawberries are bubbly.
Step 8
Remove from the oven and let them cool completely in the pan before slicing into bars.
