Key Ingredients
These pantry staples come together to make a filling, nutritious breakfast. The ingredient list is simple and easy to swap based on preference.
- Oat milk – works well as a dairy-free base; dairy or almond milk can be used instead.
- Chia seeds – absorb liquid and help thicken the oats; they need refrigeration time to achieve the right texture.
- Creamy peanut butter – use chunky if you prefer a bit more texture.
- Honey – adds natural sweetness; substitute maple syrup if serving to a baby under one year old.
- Rolled oats – avoid quick oats to prevent a mushy texture; rolled oats give the best overnight consistency.
How to make Peanut Butter Overnight Oats
These overnight oats assemble quickly in a mason jar or small container and refrigerate while you sleep. Follow the steps below for best results.
- Add chia seeds, oat milk, and honey to a mason jar and stir to combine.
- Stir in the peanut butter; it may not fully blend and will create a pleasant swirl throughout the mixture.
- Mix in the rolled oats and ensure they are fully submerged in the liquid so they soften evenly.
- Cover the jar or container and refrigerate for at least 6 hours, or overnight, until the oats reach a soft, spoonable consistency.
- After chilling, top the oats with sliced strawberries, bananas, blueberries, apples, extra peanut butter or chocolate chips, as desired.
Hint: Press the oats down into the liquid so they absorb moisture evenly. Always cover the container before refrigerating.
Top tip
For the creamy, slightly thick “mush” texture that makes overnight oats so satisfying, refrigerate the mixture fully assembled for at least 6 hours—overnight is ideal.
If serving to a baby under one year old, replace honey with maple syrup or another safe sweetener. Do not give honey to infants under 12 months.
Recipe
Peanut Butter Overnight Oats
Andrea
Ingredients
- ½ cup Oat milk or almond milk or dairy milk
- 1 tablespoon chia seeds
- 2 tablespoons peanut butter
- 1 tablespoon honey or maple syrup (do not use honey for infants under 1)
- ½ cup rolled oats
Instructions
-
In a mason jar or small container with a lid, add milk, chia seeds, honey and peanut butter. Mix—the peanut butter may remain slightly swirled, which is fine.
-
Add the rolled oats and stir, pressing them into the liquid so they are fully covered.
-
Cover tightly and refrigerate for at least 6 hours or overnight.
-
Serve plain or topped with sliced fruit, chocolate chips, nuts, or a spoonful of jelly to make a PB&J-style bowl.
Notes
- Do not use honey for children under 12 months; use maple syrup instead.
- Add a tablespoon of your preferred protein powder to boost protein.
- Swap milk types 1:1—dairy, almond, soy, or coconut milk all work.
- Greek yogurt can replace milk for a thicker texture—mix the oats and chia into the yogurt before refrigerating.
- Top with fruit, chocolate chips or nuts for extra flavor and texture.
