Servings 12


*Oat Layer:*

  • 2 cups quick-cooking oats
  • ½ cup honey
  • cup all-natural creamy peanut butter
  • cup mini chocolate chips
  • Optional: 1-2 teaspoons water

*Chocolate Layer:*

  • 6 oz. dark chocolate chopped
  • 2 teaspoons coconut oil

*Peanut Butter Layer:*

  • ½ cup all-natural creamy peanut butter
  • 1 teaspoon coconut oil
  • ¼ cup mini M&M’s
  • 2 tablespoons mini chocolate chips


  • Line your metal muffin pan with paper liners or use a silicone muffin pan without the need for liners.
  • Start with the oat layer. Mix quick-cooking oats, honey, peanut butter, and mini chocolate chips in a bowl. If it feels dry, add 1 to 2 teaspoons of water. Press about 2 tablespoons of the oats into each muffin cup.
  • Proceed with the chocolate layer. Melt dark chocolate and coconut oil in a microwave-safe bowl, stirring at 20-second intervals. Spoon 2 teaspoons of melted chocolate onto the oat layer, swirling the pan for even distribution. Freeze for 5 minutes.
  • Now, the peanut butter layer. Microwave peanut butter and coconut oil for 15 seconds, stir until well combined. Add 2 teaspoons of the peanut butter mixture on top of the chocolate layer, swirl to even it out. Sprinkle mini M&Ms and mini chocolate chips on each cup.
  • Freeze the muffin tin for at least 30 minutes to an hour to set.
  • Once set, transfer the oat cups from the muffin pan to a freezer bag and store in the freezer.


  • Avoid using rolled oats, as old-fashioned rolled oats would be too tough for these cups.
  • Ensure the oat cups are well-set before freezing for the best results.
