First prepare the crust by combining the fine ground graham crackers or cookies with the sugar & cinnamon and a pinch of salt
Add the melted vegan butter & mix to combine well, it will resemble wet sand.
Press this into the bottom & up the sides of an un-greased 9" pie plate.
Refrigerate until needed.
For the apple filling, peel & core the apples then slice them to ¼" thickness, toss them in a large bowl with the cinnamon, nutmeg & sugar
Melt the vegan butter in a saute pan over high heat, then add the apples in a single layer cooking for about 2 minutes to brown on one side then flip them around to cook the other side. (You may have to do this in 2 batches depending on the size of your pan)
Add the optional rum or brandy
Cook for about 5-7 minutes total until the apples are cooked through, tender & flexible but not mushy.
Pour HALF the apples into the bottom of the prepared cookie crust
Now prepare the custard by combing all the ingredients except for the vanilla extract & the vegan butter in a medium sauce pot over medium to high heat & bring to a boil whisking constantly to avoid scorching the bottom .
Once it starts to bubble let it boil on low heat for about 5 seconds.
Remove from the heat & add the vegan butter & vanilla extract ~ stir until melted & smooth.
Pour over the apples in the pie plate then refrigerate for about 30 minutes to slightly set, then top with the remaining apples, refrigerate to cool & set completely.
Prepare the whipped cream of your choice as per the recipe instructions & spread over the cold pie. Sprinkle with cinnamon & extra crushed graham crackers
