Start by gathering all your ingredients. Crush the vanilla wafers in a bowl until they resemble coarse crumbs. Slice your banana into thin rounds.
Begin building your parfait by adding a generous layer of vanilla Greek-style yogurt to the bottom of your bowl or cup. Use about half of the yogurt for the first layer.
Next, place a layer of banana slices over the yogurt. Aim for an even distribution to ensure every bite has some banana goodness.
Sprinkle a layer of granola over the bananas. This will add a delightful crunch that contrasts beautifully with the creaminess of the yogurt and softness of the bananas.
Now, add a layer of the crushed vanilla wafers. This will give your parfait that classic banana pudding flavor and texture.
Repeat the layers, starting with the remaining yogurt, followed by more banana slices, granola, and crushed wafers. You can create as many layers as your cup will hold, but aim for at least two or three.
If desired, finish with a dollop of whipped cream on top for an extra touch of indulgence. You can also sprinkle a few extra crushed wafers or granola for garnish.
