Start by crushing the cookies into coarse crumbs—aim for a mix of small pieces and some larger shards for texture.
In a mixing bowl, whisk together the vanilla yogurt and the orange juice until the mixture is smooth and slightly tangy in aroma.
Add the lemon zest and a pinch of salt to the yogurt mixture, then gently fold to combine. The zest will release a fresh citrus scent as you mix.
Spread a thin layer of the yogurt mixture into the bottom of each clear glass or jar.
Follow with a layer of crushed cookies, distributing evenly to create a crunchy, colorful stripe.
Repeat the process, adding another layer of yogurt, then cookies, until the glasses are filled, ending with a yogurt layer on top for a smooth finish.
Decorate the tops with a few more cookie crumbs or a small dollop of whipped cream if desired for an extra touch.
Chill the parfaits in the refrigerator for about 30 minutes to let the flavors meld and the layers set slightly.
Just before serving, add a final sprinkle of lemon zest or a tiny cookie piece for visual appeal.
Serve immediately with a spoon, allowing the layers to delight with each bite and enjoying the colorful, creamy presentation.
