How to Make It
Preheat your oven to 350°F (175°C).
Dump the berries into a baking dish.
Sprinkle the lemon juice and sugar over the berries.
In a bowl, mix together the oats, flour, and melted butter until crumbly.
Spoon the oat mixture evenly over the berries.
Bake for 25-30 minutes until the top is golden and juices are bubbling.
Serve
Let it cool for a few minutes before serving. Spoon it into bowls and enjoy the warm, jammy goodness, perhaps with a scoop of vanilla ice cream on top!
