Prep the strawberries: Hull and dice 1 cup of fresh strawberries.
If they’re not very sweet, toss with 1–2 teaspoons of maple syrup and let them sit for 5 minutes to macerate.
Mix the dry base: In a medium bowl, add 1/2 cup rolled oats, 1 tablespoon chia seeds, a pinch of salt, and 1 scoop (about 25–30 g) vanilla protein powder. Stir to combine so there are no clumps of powder.
Add the wet ingredients: Pour in 1/2 cup milk and 1/3 cup Greek yogurt. Add 1 teaspoon vanilla extract and 1–2 teaspoons maple syrup or honey.
Whisk until smooth and evenly mixed.
Fold in the strawberries: Gently stir in most of the diced berries, saving a few for topping. If you like extra strawberry flavor, add 1 teaspoon strawberry jam or a little lemon zest.
Transfer to a jar: Spoon the mixture into a jar or airtight container. Press down lightly to level the top and wipe the rim clean.
Chill: Cover and refrigerate at least 4 hours, ideally overnight.
The chia and oats will soften and thicken the mixture.
Make the “shortcake” crumble (optional): For crunch, mix 1 tablespoon crushed graham crackers with 1 teaspoon melted butter, or combine 1 tablespoon almond flour with 1/2 teaspoon coconut oil and a pinch of sugar. Set aside.
Finish and serve: In the morning, give the oats a quick stir. If they’re too thick, add a splash of milk.
Top with remaining strawberries and the crumble. Enjoy cold or let it warm to room temp for 10 minutes.
