  3. Pour in the melted butter and mix until the mixture resembles wet sand.
  4. Press about two-thirds of the oat mixture evenly into the bottom of the prepared pan to form the base.

  6. Crumble the remaining oat mixture over the jam, ensuring that no jam is exposed.
  7. Bake for 25–30 minutes until golden brown and bubbly.
  8. Cool in the pan for at least 10 minutes, then lift out using the parchment paper to cool completely on a wire rack before slicing.
