Preheat the oven to 375°F. Line a jelly roll pan with parchment paper and spray with nonstick baking spray. Set aside.
In a small mixing bowl, whisk together flour, cinnamon, ginger, nutmeg, cloves, and salt. Set aside.
In a separate bowl, use a standing mixer or electric hand mixer to combine eggs and sugar until they are foamy and pale slightly.
Mix in the vanilla, vegetable oil, and grated carrots until fully combined.
Gently fold the dry ingredients into the wet ingredients, using a rubber spatula.
Spread the batter into the prepared jelly roll pan.
Bake 15 minutes - the cake should be evenly browned across the top.
Remove the cake from the oven and allow to cool for 3-5 minutes.
Lay out a clean linen. Lift the cake from the pan and place on top of the linen, aligning one short edge of the cake with the side edge of the linen. (*see notes) Roll from short end to short end. Dusting the top of the cake with powdered sugar will help prevent the linen from sticking to the cake. Place the rolled cake on a cooling rack to cool to room temperature - about 30 minutes.
Meanwhile, prepare the cream cheese filling by beating together the butter and cream cheese until creamy. Add the vanilla and powdered sugar and beat for 2-3 minutes until smooth and fluffy.
Gently unroll the room temperature cake onto a surface dusted with powdered sugar. Peel the parchment paper off of the cake as you unroll it if you have not already done so. The two ends will still be curled slightly; it’s best to leave them curled.
Spread the filling over the cake - leaving about an inch of space at the right-hand short edge (the filling will squish an fill out this space as you re-roll it.
Working from the left-hand side, re-roll the cake, tucking it as tightly as you can while maintaining that nice layer of cream cheese filling on the inside.
Wrap the log with plastic wrap, to ensure it holds its shape. Chill in the refrigerator (or the freezer) for at least one hour more, seam side down.
When ready to serve, unwrap the cake roll, dust with powdered sugar, and slice into approximately 1” pieces.
Notes
Storage:Store carrot cake roll slices in the refrigerator, wrapped with plastic wrap, for 5-7 days. Freeze up to 1 month.Notes:The cake for this cake roll is similar to a chiffon cake. It’s light and spongy without the addition of much fat (i.e., butter) beyond the eggs. There is a little bit of oil in the batter, which adds moistness. This type of cake works well for a jelly roll - it is thin and pliable and you can roll it without the cake cracking.It is easiest to leave the parchment paper attached to the bottom of the cake when you roll it up initially. I like to use the dish towel because it feels more secure. If you use a dish towel and parchment paper, you need to dust the cake with powdered sugar to prevent the linen from sticking to the cake. If you simply roll it with parchment paper, less sticking will occur. The caveat to this is that the parchment paper kind of “steams” the cake and the exterior is a bit stickier when you remove the parchment after cooling (no one in my family seemed to notice or care and could not tell the difference.) You can also turn the cake out onto powdered sugar-dusted linen, remove the parchment paper, and then roll the cake (dust the top too) with just the towel. This eliminates the parchment paper issue, but I don’t think it ultimately makes a huge difference. Leaving the parchment on is easier. If you were not going to frost or dust the finished roll with powdered sugar, I would opt for the second method (remove parchment paper for initial cooling) as it is a bit more aesthetically pleasing.Wash and peel carrots and then grate on a box grater OR run them through your food processor fitted with the grater attachment. The number of carrots needed will depend on the size of the carrots. My carrots were particularly skinny this time and it took 6-8 carrots to get 2 cups.
