Ingredients Breakdown:
Oat Layer:
2 Cups Quick-Cooking Oats: The base of these cups, oats give them structure and chewiness. Quick-cooking oats blend easily with the other ingredients and set well.
½ Cup Honey: Honey is the natural sweetener for this layer. It helps bind the oats together while adding a pleasant sweetness.
⅓ Cup Creamy Peanut Butter: Peanut butter adds a rich, nutty flavor and creamy texture to the oat layer.
⅓ Cup Chocolate Chips: These add some melty sweetness throughout the oat layer.
2 tsp Water: Just enough water to help the mixture come together smoothly.
Chocolate Layer:
1 10 oz Package Chocolate Baking Chips (I used Ghirardelli Dark Chocolate): This rich chocolate layer provides a satisfying contrast to the chewy oat base. Dark chocolate adds depth and richness.
2 tsp Olive Oil or Coconut Oil: Helps the chocolate melt smoothly and gives it a glossy finish.
Peanut Butter Layer:
½ Cup Creamy Peanut Butter: Another layer of peanut butter goodness on top of the chocolate layer, offering a salty-sweet combo.
1 tsp Olive Oil or Coconut Oil: Ensures the peanut butter layer spreads smoothly over the chocolate.
¼ Cup Mini M&M’s: These bring a burst of color and crunch, making the cups look fun and festive!
2 Tbsp Chocolate Chips: Extra chocolate chips for an extra bit of indulgence on top.
Directions:
Prepare the Oat Layer:
Line a metal muffin tin with paper liners (or use a silicone muffin pan for easy removal).
In a mixing bowl, combine the quick-cooking oats, honey, peanut butter, chocolate chips, and water. Stir until everything is evenly combined.
Scoop about 2 tablespoons of the oat mixture into each muffin cup and press it down firmly to form a solid base.
Make the Chocolate Layer:
In a microwave-safe dish, add the chocolate baking chips and oil. Heat on high in 20-second increments, stirring between each increment until the chocolate is completely melted and smooth.
Scoop about 2 teaspoons of the melted chocolate onto the oat layer, spreading it to cover the entire surface.
Place the muffin tin in the freezer for 5 minutes to set the chocolate layer.
Prepare the Peanut Butter Layer:
In a microwave-safe bowl, combine the peanut butter and oil. Heat for 15-20 seconds until softened, then stir until well combined.
Spoon about 2 teaspoons of the peanut butter mixture on top of the set chocolate layer, spreading it evenly.
Top each oat cup with mini M&M’s and extra chocolate chips.
Freeze to Set:
Place the muffin tin back in the freezer for 30 minutes to 1 hour, or until the cups are fully set.
Once set, remove the cups from the muffin tin and transfer them to a freezer bag for storage. Keep them stored in the freezer for a quick treat anytime!
