Prep the strawberries: Hull and dice the strawberries.
If they’re very tart, toss with a teaspoon of sweetener and a tiny squeeze of lemon. Set aside.
Mix the cheesecake base: In a bowl or mason jar, whisk together the Greek yogurt, cream cheese (softened for easier mixing), vanilla extract, and a pinch of salt until smooth.
Add the protein: Stir in the protein powder. If it looks very thick, add a splash of milk to loosen it before adding the oats.
Combine the dry ingredients: Add rolled oats and chia seeds (if using).
Stir to coat everything evenly.
Adjust the liquid: Pour in milk, starting with about 1/2 cup per serving. The mixture should look slightly loose—oats will absorb liquid overnight.
Sweeten to taste: Add honey, maple syrup, or your preferred sweetener. Taste and adjust.
Aim for slightly sweeter than you think; sweetness mellows by morning.
Fold in strawberries: Gently stir in most of the diced strawberries, reserving a few for topping.
Chill overnight: Cover and refrigerate at least 4 hours, ideally overnight, to thicken.
Finish and serve: In the morning, stir, then top with reserved strawberries and a sprinkle of crushed graham crackers or granola for that “cheesecake crust” crunch.
