Make the Carrot Cake Roll Recipe: a tender carrot sponge rolled with tangy cream cheese filling for pretty spiral slices.
Preheat the oven to 375°F (190°C). Grease a 10x15-inch jelly roll pan thoroughly and line it with a sheet of parchment paper, smoothing the paper so there are no air pockets. Lightly grease the parchment as well so the cake releases cleanly later — this small step makes the rolling much easier and prevents tearing.
In a bowl whisk together the all-purpose flour, baking soda, salt, and ground cinnamon until evenly distributed, so every scoop of batter will bake with consistent spice and lift. This dry mix should look homogenous, pale, and faintly speckled with cinnamon.
In a separate mixing bowl beat the two large eggs with the granulated sugar until the mixture is noticeably thickened, pale, and ribbon-like when the whisk is lifted. You're building structure and aeration here — aim for a glossy, voluminous batter base.
Gradually stream in the vegetable oil and the vanilla extract while continuing to beat just until incorporated. The batter should become slick and slightly more fluid but still hold the air you built in the eggs.
Gently fold the flour-spice mixture into the wet ingredients with a spatula, mixing just until no dry streaks remain. Maintain light strokes to preserve the aeration from the eggs; you want tender crumb, not a dense sheet.
Gently fold in the cup of grated carrots until evenly distributed, the batter turning warm, earthy orange with tiny carrot flecks throughout. The texture becomes visibly speckled and slightly textured from the shredded vegetable.
Pour the batter into the prepared 10x15-inch pan and spread it into an even, thin layer with an offset spatula, smoothing the surface so it will bake into a uniform sheet suitable for rolling. The top should be matte, slightly glossy where oil sits, and free of large air pockets.
Bake the thin cake for about 15 minutes, or until a toothpick inserted into the center comes out clean and the top springs back lightly to the touch. The baked sheet will be a warm golden-brown, springy and flexible — exactly right for rolling.
While the cake bakes, begin the filling: beat the softened cream cheese and softened unsalted butter together until completely smooth and lump-free. The texture should be silky and cohesive, a pale creamy base for the sweetener.
Add the powdered sugar and the vanilla extract to the cream cheese mixture and beat until the filling is fluffy, glossy, and thick enough to spread without sliding. Taste for balance — it should be sweet, tangy, and smooth.
Remove the cake from the oven and immediately invert it onto a clean kitchen towel that has been generously sprinkled with powdered sugar. The sugar prevents sticking and leaves a thin dusting on the cake surface as you prepare to remove the parchment.
Carefully peel off the parchment paper, then tightly roll the cake up in the towel while still warm. This rolled towel-and-cake configuration sets the spiral memory so the cake can be filled later without cracking. Let the rolled cake cool completely in the towel before unrolling.

Once the cake has fully cooled, gently unroll it and spread the prepared cream cheese filling in an even layer across the cake, leaving a small margin at the edge to prevent overflow when re-rolled. The filling should create a smooth, snowy-white contrast against the warm carrot-speckled cake.
Using the towel as a guide, re-roll the cake tightly but gently, this time without the towel. The spiral should be even, the seam tucked underneath, and the roll should feel cohesive and slightly firm.
Place the assembled carrot cake roll in the refrigerator to chill and set for at least an hour before slicing. Chilling firms the filling and produces clean spiral slices that showcase the moist, speckled cake and the bright cream cheese swirl.
