Place all your ingredients into a mason jar. Place the lid on the jar and shake to combine.
Put the oats in the fridge and let them sit overnight.
Serve with an extra drizzle of maple syrup or even some chopped pecans.
Notes
You can store these overnight oats in the refrigerator for up to 5 days. For even longer storage, freeze them for up to 3 months in a freezer bag, jar, or airtight container. Thaw the oats overnight in the refrigerator before serving.
