Wash the strawberries and blueberries thoroughly and pat them dry. Remove the strawberry stems and chop the strawberries into small pieces. Slice the banana just before assembling the parfait to help prevent browning.
Place the yogurt in a small bowl. If you prefer a sweeter parfait, stir in honey or maple syrup. For additional flavor, add a pinch of cinnamon or a small amount of vanilla extract.
Spoon a layer of yogurt into the bottom of two clear glasses, jars, or serving bowls. Spread it gently to create an even base.
Add a layer of chopped strawberries, blueberries, and banana slices over the yogurt. Use a mixture of colors to make the parfait visually attractive.
Sprinkle granola over the fruit. Add chopped almonds, walnuts, or chia seeds if desired. For the crunchiest result, keep some granola aside to add just before serving.
Continue layering the yogurt, fruit, and granola until the glasses are filled. Finish with a generous spoonful of yogurt, a few berries, and a little granola on top.
Drizzle a small amount of honey or maple syrup over the top. Garnish with mint leaves if desired, and serve immediately for the best contrast between creamy yogurt and crunchy granola.
