Creating this delicious Peanut Butter Cup Chocolate Roll Cake can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a 15×10-inch jelly roll pan with parchment paper and lightly grease.
2. Make the Cake Batter:
– In a large bowl, beat the eggs and granulated sugar together until thick and pale.
– Add vanilla extract, flour, cocoa powder, baking powder, and salt. Mix until well combined.
3. Spread Batter: Spread the batter evenly into the prepared jelly roll pan.
4. Bake: Place in the preheated oven and bake for 15-20 minutes or until the cake springs back when lightly touched.
5. Cool the Cake: Once baked, remove from the oven and let it cool in the pan for 5-10 minutes. Then, invert the cake onto clean parchment paper, peel off the original paper, and allow it to cool completely.
6. Prepare Peanut Butter Filling:
– In a mixing bowl, combine creamy peanut butter and powdered sugar. Mix until smooth.
– In another bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the peanut butter mixture until fully combined.
7. Fill the Cake: Once the cake has cooled, spread the peanut butter filling evenly over the cake.
8. Roll the Cake: Starting from one short side, carefully roll the cake tightly. Use the parchment paper as support to help with rolling.
9. Chill: Wrap the rolled cake in parchment paper or plastic wrap and place it in the refrigerator to chill for at least 30 minutes.
10. Prepare Ganache: Melt additional chocolate for drizzling if desired.
11. Slice and Serve: After chilling, slice the cake into pieces or serve whole with a drizzle of chocolate ganache on top.

Following these steps will ensure your Peanut Butter Cup Chocolate Roll Cake tastes as incredible as it looks!
