Ingredients
Method
- Preheat your oven to 350°F (175°C). Line a 15x10-inch jelly roll pan with parchment paper and lightly grease it.
- In a large bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder.
- In a separate bowl, whisk together the buttermilk, vegetable oil, egg, vanilla extract, vinegar, and red food coloring.
- Pour the wet ingredients into the dry ingredients and mix with an electric mixer until just combined. Do not overmix.
- Pour the batter into the prepared jelly roll pan and spread it evenly. Bake for 12-15 minutes.
- While the cake bakes, lay a clean kitchen towel on a flat surface and dust it generously with powdered sugar.
- Once the cake is done, invert it onto the sugared towel and carefully peel off the parchment paper.
- Starting from one of the short ends, roll the cake and towel together into a tight spiral and let it cool on a wire rack for 1-2 hours.
- For the frosting, beat the cream cheese and butter until light and fluffy, then gradually add the powdered sugar. Mix in the vanilla extract and salt.
- Once the cake is cool, unroll it and spread an even layer of frosting on the surface.
- Re-roll the cake without the towel and chill it in plastic wrap for at least 30 minutes before serving.
Notes
Be careful not to overbake the cake as it can become dry and crack; roll the cake while it's warm for best results.
