Gather your jars. Use clean, dry 12–16 oz jars with tight lids. This size leaves space for stirring and toppings.

Mix the wet base. In a bowl, whisk 1 cup milk, 1/2 cup Greek yogurt, 1 scoop protein powder, 1–2 teaspoons maple syrup, 1/2 teaspoon vanilla, and a pinch of salt until smooth. If the protein powder clumps, sift it in or whisk longer.

Add the dry ingredients. Stir in 1 cup rolled oats and 1 tablespoon chia seeds. The mixture should look loose; it will thicken as it chills.

Portion into jars. Divide the mixture between two jars for two servings. For a week’s worth, multiply the base and keep ratios the same.

Add mix-ins wisely. Stir in sturdy add-ins like cocoa powder, cinnamon, or nut butter now. Save fresh fruit and crunchy toppings for the morning to avoid mushiness.

Chill. Seal the jars and refrigerate at least 4 hours, ideally overnight. The oats soften and the chia thickens the mixture.

Finish and enjoy. In the morning, open a jar, give it a stir, and add toppings like berries, sliced banana, nuts, or a drizzle of nut butter. If it’s too thick, add a splash of milk.

Pack and go. Keep a spoon in your bag and you’re out the door.
