Caramel-Filled Carrot Cake Roll

Step 1
Combine carrots and 1 teaspoon sugar in a saucepan; add water to cover. Cover the pan, bring to a boil over medium-high heat, and cook until fork tender, 3 to 4 minutes. Drain carrots, mash with a fork, and set aside to cool.

Step 2
Preheat the oven to 375 degrees F (190 degrees C). Grease two 10×15-inch baking pans and line with parchment paper. Lightly grease parchment paper and dust with flour.

Step 3
Combine flour, cinnamon, baking powder, and salt in a medium bowl.

Step 4
Beat eggs in a large bowl with an electric mixer on high speed for 5 to 7 minutes. Beat in 2 cups white sugar until thick. Mix in mashed carrots and vanilla extract. Fold in flour mixture. Spread batter into the prepared baking pans and sprinkle with walnuts.

Step 5
Bake in the preheated oven until top springs back when lightly touched, 10 to 12 minutes.

Step 6
While cakes are baking, dust 2 linen towels with confectioners' sugar.

Step 7
Remove cakes from the oven and cool on a wire rack for 5 minutes. Run a table knife around the edges to loosen. Invert each cake carefully onto the sugar-dusted towels. Peel off parchment paper and roll cakes up in the towels to cool.

Step 8
Meanwhile, combine cream cheese, butter, caramel topping, and vanilla extract for the frosting in a large bowl; beat with an electric mixer until smooth and creamy. Gradually mix in confectioners' sugar until fluffy.

Step 9
Carefully unroll cakes and spread filling to 1 inch from the edges. Roll up cakes, cover, and chill until serving.
