Ingredients

  • 1 cup milk (whole or 2% for richness)
  • 1 cup chocolate chips (semi-sweet or milk chocolate)

Step-by-Step Instructions

  • Grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Layer the Cake Mix

Step 3: Add the Peanut Butter & Milk

  • In a microwave-safe bowl, melt the peanut butter (about 30 seconds).
  • Drizzle the melted peanut butter evenly over the cake mix.
  • Slowly pour the milk over the top, covering as much surface area as possible.

Step 4: Sprinkle the Chocolate Goodness

  • Scatter the chocolate chips and chopped peanut butter cups over the top.
  • Optional: Lightly swirl with a knife for a marbled effect.

Step 5: Bake to Perfection
