Method
Prep and pre-bake the oat crust
- Preheat the oven to 375F, and line a 9x13 pan with parchment.
- Combine the rolled oats, all-purpose flour, brown sugar, cinnamon, and salt, then cut in the cold unsalted butter until crumbly.
- Reserve 1 cup of the oat mixture for the topping and press the rest firmly into the pan.
- Bake the crust for 12 minutes.
Fill, top, and bake
- Whisk the pumpkin puree, evaporated milk, eggs, granulated sugar, pumpkin pie spice, cinnamon, ginger, salt, and vanilla until smooth.
- Pour the filling over the hot crust.
- Scatter the reserved oat crumble over the filling.
- Bake for 35 to 40 minutes at 375F until the topping is golden and the filling is set.
Cool and chill
- Cool the bars completely.
- Refrigerate for 1 hour before cutting for clean slices.
Notes
Pro tip: press the crust firmly and keep the butter cold so the base bakes into a sturdy, sandy crumble. Store covered in the refrigerator for up to 4 days; freeze baked bars for up to 2 months. For a dairy-free swap, replace evaporated milk with an unsweetened plant-based evaporated milk alternative (choose one labeled heat-safe).
