Ingredients Method Notes

Ingredients
  

For the cake
  • 1 box Chocolate cake mix (plus required ingredients)
  • 1/2 cup Melted butter
For the peanut butter layer
  • 8 oz Softened cream cheese Make sure it's truly softened for a smooth mixture.
  • 1/2 cup Creamy peanut butter
  • 1/2 tsp Vanilla extract
  • 4 cups Powdered sugar Adjust to taste if using Greek yogurt.
For topping
  • 1/2 cup Semi-sweet chocolate chips
  • 1 cup Mini Reese’s Cups, halved Chop some if too large for the pan.

Method
 

Preparation
  1. Preheat your oven to 350°F and grease a 9 by 13 inch glass baking dish.
  2. Prepare the chocolate cake batter as directed and pour it into the dish.
  3. Beat cream cheese and melted butter until smooth.
  4. Add peanut butter and vanilla, then slowly whip in the powdered sugar until fluffy.
  5. Spoon large dollops of the peanut butter mixture over the raw batter, do not swirl!
  6. Scatter chocolate chips and Reese’s halves across the top.
Baking
  1. Bake for 45 to 55 minutes until the center is set.
Serving
  1. Serve it warm straight from the oven — that’s when the cake is at its most affectionate.
  2. Add a scoop of vanilla ice cream or a drizzle of warm caramel if you’re feeling extra indulgent.

Notes

Store cooled cake tightly covered in the refrigerator for up to 4 days. For reheating, microwave a slice for 15–25 seconds or bake at 300°F for 10–12 minutes covered with foil.
