Cut a small piece of parchment paper and place it on one of the muffin cups. Then place the bottom of a small cup over that and press down. Repeat this process for the remaining cups.
This is what your granola cups should look like after pressing them down with the small, glass cup. It now looks like a small bowl. Bake at 350°F for 30-35 minutes.
A fun brunch idea would be to set up a breakfast/brunch bar with different yogurts and toppings. This way, everyone can have fun customizing their granola cups to their liking.
