These wholesome caramel apple crumble bars feature a buttery oat crust, tender cinnamon-spiced apples, and a gooey caramel layer. They come together in under an hour and are perfect for bake sales, cozy weekends, or last-minute desserts.
Keep butter cold for a flaky crust. Don’t skip the parchment paper for easy removal. Cool completely before cutting to prevent crumbling. For extra flavor, toast the oats before mixing. If using frozen apples, thaw and drain well.
