Prep the blueberries: Rinse and dry the blueberries. If using frozen, thaw and pat dry to avoid excess moisture.
Toast the oats (optional): In a dry skillet over medium heat, cook the oats for 3–4 minutes until lightly golden and nutty. Let cool.
Mix the yogurt base: In a bowl, stir together the Greek yogurt, honey, vanilla, lemon juice, lemon zest, and a pinch of salt until smooth.
Taste and adjust sweetness.
Layer the dessert: In glasses, jars, or a small dish, add a layer of oats, then spoon in the yogurt. Scatter blueberries on top. Repeat the layers until you reach the top.
Add crunch: Sprinkle nuts or seeds and coconut over the final blueberry layer.
Finish with honey: Drizzle a little honey over the top for shine and extra sweetness.
Chill briefly: Refrigerate for 15–30 minutes to let the layers settle and the oats soften slightly (or enjoy right away for extra crunch).
