4.4 from 50 reviews

These Reese’s Peanut Butter Cup–Inspired Overnight Oats capture the classic candy flavor by combining oats with crunchy peanut butter and chocolate chips, both stirred in and melted on top to mimic the candy's shell. Flaky sea salt enhances the balance of sweetness, and the recipe offers flexibility with nut butters, making it a delicious and convenient make-ahead breakfast.

  • Total Time: 12 hours 55 minutes
  • Yield: 4 servings

Ingredients

Oat Mixture

  • 2 cups old-fashioned rolled oats
  • 2 cups unsweetened almond milk
  • 1 cup whole-milk plain strained (Greek-style) yogurt
  • 1/3 cup crunchy natural peanut butter, well stirred
  • 2 tablespoons mini semisweet chocolate chips
  • 1 teaspoon vanilla extract

Chocolate Topping

  • 3 tablespoons mini semisweet chocolate chips
  • 1 1/2 teaspoons unrefined coconut oil
  • 1/4 teaspoon flaky sea salt

Instructions

  1. Mix oat ingredients: In a large bowl, whisk together the rolled oats, almond milk, Greek yogurt, crunchy peanut butter, 2 tablespoons of mini semisweet chocolate chips, and vanilla extract until well combined. Refrigerate uncovered for about 30 minutes until the mixture is set and slightly thickened.
  2. Melt chocolate topping: While the oats chill, place the remaining 3 tablespoons of mini semisweet chocolate chips and the coconut oil in a small microwave-safe bowl. Microwave on high for 45 to 60 seconds, then stir until the chocolate chips are completely melted and combined with the oil, creating a smooth chocolate mixture.
  3. Assemble jars: Divide the oat mixture evenly among 4 jars (8-ounce each), filling about 1 cup per jar. Spoon approximately 2 teaspoons of the melted chocolate mixture onto the surface of each jar, tilting slightly to cover the top evenly.
  4. Set chocolate topping: Refrigerate the jars uncovered for about 10 minutes to allow the chocolate layer to set just enough.
  5. Finish and store: Sprinkle flaky sea salt over each jar's top chocolate layer, then cover and refrigerate for at least 12 hours or up to 4 days until the oats have thickened fully and the chocolate topping is completely solidified. Serve chilled.

Notes

  • Crunchy peanut butter provides texture, but creamy peanut butter or alternatives like almond or sunflower butter work well too.
  • The flaky sea salt on top balances the sweet chocolate and peanut flavors.
  • This recipe is make-ahead friendly and can be stored refrigerated for up to 4 days.
  • Use gluten-free oats if you require the recipe to be gluten-free.
  • For a dairy-free version, substitute Greek yogurt with a plant-based yogurt of similar thickness.
