  • Chocolate Cake Mix: Acts as the base, making this recipe quick and foolproof. You can use dark chocolate for a more intense flavor.
  • Vegetable Oil, Eggs, and Water: Provide structure and moisture to the cake batter.
  • Peanut Butter: The star of the recipe, adding nutty creaminess and depth.
  • Cream Cheese: Creates a luscious swirl that balances sweetness with tang.
  • Powdered Sugar: Sweetens the peanut butter and cream cheese filling without making it grainy.
