Instructions

    Cup of Yum
  1. Get out and measure all of your ingredients.
  2. Preheat the oven to 350°F. Line a 9x13 with foil and spray with cooking spray, set aside.
  3. In a medium-sized bowl add the butter and chopped chocolate. Microwave for 30 seconds, stir. Microwave for another 30 seconds, stir.
  4. Start microwaving at 15-second intervals stirring in between until the mixture is melted. Stir in the vanilla and set aside.
  5. In the bowl of a stand mixer with the paddle attachment add the flour, sugar, brown sugar, cocoa powder, baking soda, and salt,
  6. Stir to combine.
  7. At low speed add in the eggs one at a time until mixed in. Turn the mixer on medium and let it mix for 2 minutes, scrape down the sides.
  8. Turn the mixer on low and slowly stream in the melted chocolate mixture until combined. Add the chocolate chips.
  9. Just mix them in so they are incorporated through the batter. This mixture will be very thick.
  10. Press the brownie batter into the bottom of the baking dish, I find using my hands to spread it out easiest.
  11. Bake for 25-30 minutes until the top is set, no longer glossy, and the edges slightly puff up. You can take an internal temperature, if the brownies are 165°F they are done.
  12. Let cool on a wire rack completely.
  13. Once the brownies are cooled, make the topping.
  14. Place the cream cheese in a large bowl. With an electric hand mixer beat it until smooth.
  15. Add the powdered sugar.
  16. Mix until smooth.
  17. Add the peanut butter and vanilla.
  18. Mix until smooth.
  19. Fold in the whipped topping until smooth
  20. Make sure there are no streaks left, this can take a couple of minutes.
  21. Smooth the peanut butter mixture on top of the brownies. Cover and place in the fridge for at least 4 hours or overnight.
  22. Use the foil to help lift the brownies out of the pan. Cut into bars.
  23. Drizzle with optional melted chocolate bark.
  24. Serve as is or with your favorite toppings such as whipped cream, chopped peanuts, chocolate chips, or Reese’s pieces!
  25. Enjoy
  26. every bite!
  27. Notes
  28. These brownies need to be kept in the fridge. However, the brownie will be too hard if they are super cold. I suggest letting the brownies sit out for 5-10 minutes before serving so they are not super cold.
  29. The addition of chocolate chips in the batter is completely optional, I personally like the texture they bring to the brownies.
  30. Dense, fudgy brownies topped with light and fluffy peanut butter pie filling. The addition of the chocolate on top is a little crisp welcomed garnish but again this can be optional.
  31. You can even put peanut butter chips or Reese’s Pieces in the brownie batter to add more peanut butter flavor throughout!
