2 cups gluten-free oats Shop
2 cups milk
0.5 cup creamy peanut butter Shop
2 tbsp maple syrup or honey Shop
1 tsp pure vanilla extract Shop
0.5 tsp salt
Optional chia seeds Shop

Instructions

1 In a large bowl or individual containers, combine the gluten-free oats and milk. Stir well to ensure all the oats are submerged and there are no dry clumps.
2 Add the creamy peanut butter, maple syrup (or honey), pure vanilla extract, and salt to the oat and milk mixture. Stir vigorously until the peanut butter is fully incorporated and the mixture is smooth and creamy, about 1-2 minutes.
3 If using, stir in the optional chia seeds. These will help thicken the oats as they soak. Ensure everything is thoroughly mixed together for even distribution of flavors.
4 Cover the containers tightly with lids or plastic wrap. Place them in the refrigerator for at least 8 hours, or preferably overnight, allowing the oats to soften and the flavors to meld beautifully.
5 Before serving, give the overnight oats a good stir. If the mixture is too thick for your liking, you can add a splash more milk to reach your desired consistency. Serve chilled and enjoy your delicious breakfast.

Tips & Notes

Stir the peanut butter into a little warm milk first. It mixes in smoothly instead of staying in clumps.
Top the peanut butter oats with sliced banana or a few chocolate chips labeled gluten-free in the morning.
If your peanut butter already contains salt, reduce the 0.5 tsp salt in the oats so they don't taste salty.
