In a mini muffin pan, layer just over half of the granola. Divide berries evenly on top of the granola. Spoon a tablespoon of yogurt into each cup. Tap the muffin pan on the counter a few times to remove air pockets. Sprinkle remaining granola on top. Cover and freeze for at least 3 hours.
Before serving, place bottom of pan in warm water for a few seconds. Use a plastic knife to pop out the yogurt bites. Serve within a few minutes, or place in ziplock bags and return to freezer.
