I start by whisking the Greek yogurt, honey, and vanilla extract together in a mixing bowl until it's smooth and evenly sweetened. This step only takes a minute, but it makes a big difference in flavor since the honey doesn't stay clumped in one spot. I also stir in the chia seeds here so they have time to soften slightly while I prep everything else.
While the yogurt mixture rests, I wash and slice my berries and banana so everything is ready to go. I like to keep the granola in a separate bowl until I'm ready to layer, since it stays crunchier that way. If I'm using nuts, I chop them roughly here too, so they're ready for the top layer or mixed in between.
Now comes the fun part. I spoon a layer of the yogurt mixture into the bottom of each glass, followed by a layer of berries, then a sprinkle of granola. I repeat this two or three times depending on the size of my glass, finishing with a final dollop of yogurt on top so the parfait looks neat and full.
Once everything is layered, I top each parfait with a few slices of banana, a scatter of chopped almonds, and a fresh mint leaf for color. If I'm not eating it right away, I pop it in the fridge for about 15 minutes so the flavors settle together a bit before digging in.
