Start by coring and slicing 6 pears in half and arrange cut side up in your crock pot. {I lined my crock pot with foil so make clean up a cinch!}
Next mix the oatmeal, brown sugar, cinnamon, and maple together in a medium bowl.
Layer the streusel on top of the apples to cover the top then sprinkle the top with pats of butter.
Bake on High for 2 hours or low for 4 hours.
