This cinnamon apple crisp with oat pecan crumble is a forgiving, foolproof dessert that feeds a crowd with zero stress. The combination of soft, cinnamon-spiced apples and a buttery, nutty crumble is pure comfort food, perfect for any gathering or cozy night in.
For the best texture, use firm apples that won’t turn to mush during baking. If you only have soft apples like McIntosh, reduce the baking time by 5-10 minutes. For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The crumble works beautifully with oat flour too. Toasting the pecans first brings out their natural oils and adds a deeper, nuttier flavor. Let the crisp rest for at least 15 minutes before serving to allow the filling to set up. This crisp can be assembled up to 24 hours ahead and refrigerated; add about 10 minutes to the baking time when baking from cold.
