1 teaspoon canola oil
1 teaspoon butter
3 pounds apples (about 8 medium), such as Cortland, Jonathan, McIntosh, Northern Spy or Gravenstein, peeled, cored and sliced (10 cups)
1/2 cup pure maple syrup
1/2 teaspoon ground cinnamon
1/2 teaspoon vanilla extract
Heat oil and butter in a large nonstick skillet over medium-high heat. Add apples (the pan will seem quite full, but the apples will cook down considerably) and cook, stirring from time to time, for 5 minutes.
Add maple syrup and cinnamon; cook, stirring or shaking the pan from time to time, until the apples are tender and the filling has thickened, about 10 minutes longer. Stir in vanilla.
Use to fill French toast or crepes.
