Measure your base: In a jar or bowl, add 1/2 cup rolled oats and 1 teaspoon chia seeds.
Whisk the wet ingredients: In a separate bowl, whisk 1/2 cup milk, 1/3 cup Greek yogurt, and 1 scoop protein powder until smooth. Add 1/2 teaspoon vanilla and a small pinch of salt.
If you like it sweeter, add 1–2 teaspoons maple syrup or honey.
Combine: Pour the wet mixture over the oats and chia. Stir well, making sure to break up any protein powder clumps.
Add blueberries: Fold in 1/2 cup blueberries. If using frozen, add them straight from the freezer.
For extra brightness, stir in a little lemon zest.
Adjust thickness: If it seems too thick, add another splash of milk. The chia will thicken everything as it chills.
Cover and chill: Seal your container and refrigerate at least 4 hours, ideally overnight.
Finish and serve: In the morning, stir again. Top with a few more blueberries, a drizzle of maple syrup, or a sprinkle of granola for crunch if you’d like.
