Preheat your oven to 350°F and line a baking dish with parchment paper for easy removal.
Mix oats, flour, brown sugar, and butter until it forms a crumbly mixture.
Press half of the oat mixture into the pan to form the base layer.
Spread strawberry preserves evenly over the crust for a fruity filling.
Sprinkle the remaining oat mixture on top for a crunchy crumble.
Bake for 30-35 minutes until golden brown, then let cool before cutting.
These cupcakes are simple to make but full of bold, delightful flavors.
