Core and slightly hollow out the apples. Do not remove too much fruit or the apples will lose shape when baked.
In a small bowl combine oats, flour, brown sugar, cinnamon, nutmeg, and spices. Cut in vegan butter, mixing by hand until fully combined and oats mixture resembles fine crumbs.
Scoop oat mixture into the apple, packing lightly.
Place in baking dish and bake apples for 30-35 minutes. Remove from oven and let cool.
To make the caramel sauce combine sugar and water (just enough to cover sugar) in a small pot over high heat and bring to boil. Do not stir; agitating the sugar will cause crystallization. Continue boiling for 5-10 minutes until the sugar has melted and begins to turn a rich golden brown.
Immediately remove from heat and slowly add non-dairy creamer while whisking. The caramel will bubble up quite a bit so use caution while adding creamer. Let caramel set for 20 minutes to thicken.
When ready to serve, top each apple with caramel sauce and serve warm.
Notes
Make Inside-Out Pear Crisps by replacing apples with pears. Before hollowing out, slice the bottoms off of the pears so they stand up straight. Bake for 20-25 minutes at the same temperature.
