1. Preheat the oven to 350°F (175°C) and line a 15×10 inch jelly roll pan with parchment paper.

2. In a bowl, whisk together the flour, baking powder, ginger, cinnamon, nutmeg, cloves, and salt.

3. In a separate bowl, beat the eggs and brown sugar until thick and creamy.

4. Stir in the molasses, melted butter, and vanilla.

5. Gradually add the dry ingredients to the wet ingredients and mix until just combined.

6. Pour the batter into the prepared pan and spread evenly.

7. Bake for 12-15 minutes or until a toothpick comes out clean.

8. Once baked, remove from the oven and let cool for a few minutes, then invert onto a clean kitchen towel dusted with powdered sugar.

9. Roll the cake up in the towel and let it cool completely.

10. For the frosting, beat together the powdered sugar, softened butter, cream cheese, vanilla, and milk until smooth and creamy.

11. Unroll the cooled cake and spread the frosting evenly over the surface.

12. Roll the cake back up without the towel and place onto a serving platter.

13. Decorate with additional frosting and festive toppings if desired before serving.
