A 4-ingredient miracle that tastes like you spent hours on it. The pumpkin layer stays silky and spiced, while the cake mix on top transforms into something between a crisp and a crumble.
Do not use pumpkin pie filling; use 100% pure pumpkin puree. Do not prepare the cake mix according to box directions; use it dry. Let the cake cool completely before cutting to allow the filling to set. For a crunchier top, use cold, thinly sliced butter instead of melted butter. Store covered in the refrigerator for up to 5 days. Freezes well for up to 3 months.
