For crumble, preheat oven to 300 F. Line baking sheet with parchment paper.
In large mixing bowl, combine all ingredients and mix to combine. Spread oat mixture evenly over lined baking sheet. Bake for 25 to 30 minutes, giving it a light stir midway, until lightly golden. Let cool completely and store in airtight container until needed.
For pears, preheat oven to 375 F.
In small baking dish, pour chai tea, and place pears, cut side down. Divide butter and place around pears. Bake for 20 minutes, then gently turn pears over and spoon a small amount of liquid overtop. Bake for another 20 to 30 minutes.
While pears are baking, in small bowl, mix brown sugar and cinnamon together. With 5 to 10 minutes of cooking left, top pears with cinnamon sugar.
Serve pears warm, topped with granola crumble. Make it even more special with non-dairy or regular cream, yogurt, or ice cream.
