CREATING THE APPLE MIXTURE
Melt 1 stick butter in a pan on your stovetop on medium heat.
Add in 1 tsp vanilla extract, 1/2 tsp cinnamon, and 3 Tbsp of brown sugar and a pinch of salt.
Add sliced granny smith apples and toss.
Cook the apples until they are soft and there is a beautiful caramel brown apple syrup at the bottom of the pan - around 10-12 minutes. You may need/want to add in additional butter and brown sugar to create more syrup to coat your french toast.
