In a mixing bowl, combine granola and melted butter.
Stir and let sit for about 5 minutes to allow the granola to soak up the butter.
Fill each hole in a silicone mold about halfway with granola and use the back of a spoon to pack it down.
Stir greek yogurt well and fill each hole the rest of the way to the top. Put 2-4 blueberries on the top of each yogurt bite and press them down so they sit into the yogurt.
