In the bottom of 2 glass jars or similar containers, layer about 1/3 cup of the yogurt. (If you're using jam or pie filling, you can add it at the bottom and then add the yogurt.) Next, add a layer of fruit, then a layer of granola, along with any other optional mix-ins.
Repeat the layers once or twice more, depending upon how thick you would like them. Finish with a sprinkle of granola and a drizzle of sweetener (if using).
Notes
Nutritional information is calculated with yogurt, mixed berries, and granola.
TO STORE: Refrigerate for up to 4 days. If you're making yogurt parfaits for meal prep, you may want to add the granola just before serving.
