Mix it tonight, eat it tomorrow. Peanut butter and banana overnight oats are a high protein breakfast that requires exactly zero morning effort.
In a medium mixing bowl, combine rolled oats, chia seeds, and a pinch of salt to ensure even seasoning.
Mash the ripe banana thoroughly, then add to the dry mixture along with peanut butter, stirring until well incorporated.
Mix in Greek yogurt, milk, honey, and vanilla extract, making sure to blend until the mixture is smooth and homogeneous.
Transfer the oat mixture evenly into two glass jars or airtight containers, smoothing the tops for uniform hydration.
Cover and refrigerate for at least 6 hours, preferably overnight, to allow oats to fully absorb moisture and achieve a creamy texture before serving.
