Blueberry Muffin Overnight Oats Ingredients

  • OATS: Plain old-fashioned rolled oats and not quick or instant oats. Quaker also carries an overnight oats version as well that is suitable for making the recipe.
  • MILK: Almond milk, cashew milk, half & half, heavy cream, coconut milk, oat milk or cow’s milk.
  • SWEETENER: Overnight oats are sweet enough as is, however maple syrup is my favorite choice of sweetener, especially for a dessert like breakfast. Other sweeteners, such as coconut sugar, brown sugar, and honey work as well.
  • TOPPINGS: Fresh fruit and nuts like blueberries and walnuts or pecans add delicious texture. Add the toppings in the next morning.
