Place the pie crust in a pie plate and flute edges if desired, set aside.
With a hand mixer beat eggs until light and fluffy.
Add in the granulated sugar, brown sugar, flour, cinnamon and beat until well combined.
Next add the corn syrup, melted butter and vanilla and beat until incorporated.
Lastly fold in the oatmeal.
Pour into the prepared pie crust and cook for 45 -55 minutes. Until the center has no jiggle.
Let cool fully about 3-4 hours before slicing. Serve with ice cream if desired.
Store leftovers (covered) in the refrigerator for 3 days. This pie can be frozen. Cover pie very well or store in an airtight container so that it doesn't get freezer burned and it will stay good for up to 3 months.
