Crust: In a food processor, pulse Nilla Wafers until crumbly. Add softened butter and Nilla Wafer crumbs to a large bowl, and thoroughly mix by hand until well incorporated. Using a 9.5 - 10 inch tart pan, press mixture into the bottom of the pan, and along the sides to form a crust. Place in the refrigerator to chill while preparing the bananas.
3. Step
Filling: Cover a sheet pan with parchment or foil and roast bananas, 25 - 30 minutes, uncovered. Let bananas rest and cool, about 15 minutes. Once cooled, in a mixing bowl, peel and add bananas to the bowl, along with the sweetened condensed milk, brown sugar, cinnamon, nutmeg, eggs, and egg yolks. Using a mixer, mix until thoroughly combined, about 1 minute. Remove pie crust from the refrigerator. Pour filling into chilled pie crust. Using a covered sheet pan, place the tart pan on a baking sheet and bake for 30 minutes, or until filling is set.
4. Step
Cool at room temperature, at least one hour. For a decorative touch, immediately before serving, add whipped cream or meringue on top. Or, serve a side of whipped cream with each slice.
