Preheat oven to 350°F (180°C). Line a baking sheet with parchment paper, ensuring it covers the sides. Spray lightly with cooking spray to keep parchment in place.

In a bowl, beat eggs and granulated sugar for 5 minutes until tripled in volume and pale yellow. This creates the air bubbles needed for a light rollable cake.

Sift cocoa powder, all-purpose flour, baking powder, and salt together. Gently fold into the egg mixture using a rubber spatula, maintaining aeration.

Spread batter evenly onto prepared pan using an offset spatula. Tap gently to remove large bubbles. Bake for 10 minutes or until the center springs back when touched.

Lay a clean kitchen towel on a flat surface and dust generously with powdered sugar. Invert the hot cake onto the towel immediately after baking to prevent cracking.

Whip heavy cream to soft peaks. Fold in powdered sugar and peanut butter until combined. Adjust thickness by adding a tablespoon of cream if too stiff or refrigerating briefly if too loose.

Unroll the cooled cake carefully. Spread filling evenly, leaving a 1/2 inch border. Sprinkle chopped mini peanut butter cups over the filling. Gently roll the cake back up, creating a tight spiral without overpressure.

Dust the top with powdered sugar. Slice and serve immediately, or refrigerate until needed.
