Ingredients
  

For the Cake Base
  • 1 box Chocolate Cake Mix A convenient choice that provides a rich foundation for this dessert.
  • 1 cup Water Adds moisture; feel free to swap it with milk for a creamier cake.
  • 1/2 cup Vegetable Oil Ensures the cake stays tender and moist; melted butter works as a delightful alternative.
  • 3 large Eggs Essential for binding the ingredients together, contributing to the cake’s delicious structure.
For the Peanut Butter Swirl
  • 1 cup Peanut Butter Creates luscious swirls; creamy works best for a smooth mix while crunchy adds character.
  • 1 cup Powdered Sugar Sweetens the mixture and helps it hold its shape.
  • 1/4 cup Melted Butter Enhances richness and aids in spreading the peanut butter mixture easily.
  • 1 teaspoon Vanilla Extract Boosts the overall flavor.

  • 1 cup Chopped Reese’s Cups Adds delightful chocolate-peanut butter bursts to each slice.
  • 1/2 cup Chocolate Chips Optional, but they provide additional richness.

  1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
