Lupin Free Apple Crisp with Cinnamon Walnut Topping
Warm, bubbling apple filling crowned with a golden, crunchy walnut-oat topping — this is the kind of dessert that makes the whole kitchen smell like autumn. Tart apple slices get tossed with fresh lemon juice, maple syrup, cinnamon, and ginger before baking into a jammy, fragrant base that pairs perfectly with the rustic crumble above. The topping leans on gluten free rolled oats, roughly chopped walnuts, and almond flour bound together with coconut oil and a drizzle of pure maple syrup, so every bite has serious texture and depth. Lupin flour has quietly crept into a surprising number of baked goods and packaged crumble mixes, making store-bought options trickier to navigate than they should be — this recipe keeps things clean and completely free of that concern. Everything here is straightforward pantry-friendly ingredients with no hidden surprises, which means you can focus on the good stuff: that deeply caramelized, clumping topping that shatters just slightly when you dig in. Let it rest for a few minutes after it comes out of the oven so the filling thickens up beautifully before you serve it. It's genuinely one of those desserts that disappears fast, so you might want to double the batch.
