Warm, bubbling apple filling beneath a golden, crumbly oat topping — this is the kind of dessert that makes the whole kitchen smell incredible. The filling comes together with fresh sliced apples, maple syrup, a touch of Ceylon cinnamon, and arrowroot starch, which thickens everything into a glossy, jammy layer without any grain-based thickeners to worry about. The topping uses rolled oats and almond flour worked together with cold butter until it forms those irresistible clumpy crumbs that bake up crisp and nutty. Lupin flour has quietly crept into a surprising number of baked goods and gluten-free products, so making your own crisp from scratch is the cleanest way to stay clear of it entirely. Every ingredient here is straightforward and easy to verify, which means you can focus on the good part — scooping out a generous portion while it's still warm. Let it rest just long enough for the filling to settle, then serve it as-is or with a scoop of vanilla ice cream alongside.
