Choose your container: Use a jar or lidded container that holds at least 12 ounces. A clear jar makes it easy to see the texture.
Combine the wet ingredients: In the jar, whisk together milk, peanut butter, honey or maple, vanilla, and a pinch of salt until smooth.
If your peanut butter is stiff, microwave it for 10β15 seconds first.
Add the protein: Stir in the protein powder or Greek yogurt until fully blended. Tip: If using powder, whisk it with a splash of milk first to avoid clumps.
Stir in the dry ingredients: Add oats and chia seeds. Mix thoroughly so every oat is coated. The chia will thicken the mixture as it chills.
Adjust sweetness and thickness: Taste the liquid.
Add a little more sweetener if needed. If it seems very thick already, splash in more milk.
Seal and chill: Cover and refrigerate for at least 4 hours, or overnight for best texture.
Finish and serve: In the morning, give it a good stir. If itβs too thick, add milk a tablespoon at a time.
Top with sliced banana, berries, chopped peanuts, or a drizzle of peanut butter.
