What you need:
Glass Container (I used an empty Bath & Body Works large candle jar)
Coffee (I mixed Hazelnut & French Vanilla)
Vanilla Tea Lights (I liked the Better Homes ones from Walmart the best)

Instructions:
Grab your glass container (decorative bowl, mason jars...etc work well too), fill it up with coffee beans and pop a tea light candle right into the center. Light the candle and as the candle warms it'll heat the beans fill the room with an amazing aroma. Each time you light a new candle make sure to shake around the beans to energize the scent.

Note: I just made this with pumpkin spice coffee and the aroma is amazing.
