These apple pie bars have that same warm, spiced filling you crave in a classic pie, but with a buttery oat crumble that adds incredible crunch. No rolling dough, no fussing with a lattice top—they’re forgiving, foolproof, and taste like a hug in dessert form.
Keep everything cold for a flaky crust. Don’t skip pre-baking the crust to prevent sogginess. Slice apples uniformly for even cooking. Cool completely before slicing to allow filling to set. Bars taste even better on day two. For gluten-free, use certified gluten-free oats and a 1:1 gluten-free flour blend. For dairy-free, swap butter with cold coconut oil or vegan butter.
