Method
- Preheat your oven to 350°F (175°C). Line a 10x15-inch jelly roll pan with parchment paper and grease it lightly.
- In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
- In a large bowl, beat the eggs and sugar for 3-5 minutes until thick and pale.
- Slowly mix in the oil and vanilla, then alternate adding the dry ingredients and buttermilk, starting and ending with dry mix.
- Pour batter into the pan and spread evenly. Bake for 12-15 minutes.
- While the cake bakes, lay a clean kitchen towel on the counter and dust it with powdered sugar.
- Once baked, immediately invert the cake onto the sugared towel and peel off the parchment paper.
- Roll the cake up from the short end with the towel inside and let it cool completely on a wire rack.
- In a large bowl, beat together softened butter and peanut butter until smooth. Add powdered sugar and vanilla, mixing at low speed. Then add heavy cream and beat until fluffy.
- For the ganache, microwave chocolate chips and heavy cream in 30-second bursts, stirring until smooth. Set aside to cool slightly.
- Unroll the cooled cake and spread the peanut butter filling evenly over the surface, leaving a small border.
- Carefully re-roll the cake without the towel and place seam-side down on a serving plate.
- Pour the ganache over the top and sprinkle with mini peanut butter cups.
- Chill the cake roll for at least an hour before slicing for clean cuts.

Notes
For buttermilk, mix 1/2 cup milk with 1/2 tablespoon lemon juice or vinegar. Use crunchy peanut butter for extra texture or almond butter for a nutty twist. To store, wrap in plastic and refrigerate for up to 4-5 days or freeze for up to 2 months, thawing in the fridge. For clean slices, chill the cake roll in the fridge before cutting, using a warm knife for neat edges.
