Method
- Heat oven to 350°F (175°C). Grease two 8-inch round pans and line the bases with parchment. Whisk flour, baking powder, baking soda, cinnamon and salt.
- Whisk eggs, both sugars, oil and 1 teaspoon vanilla until combined. Fold in dry ingredients just until no dry patches remain, then fold in carrots and optional walnuts. Divide evenly between pans.
- Bake for 30–35 minutes until centers spring back lightly and a tester comes out without wet batter. Cool in pans for 15 minutes, then turn onto racks and cool completely, at least 1 hour.
- Beat butter until smooth, then beat in cream cheese just until blended. Add powdered sugar gradually and remaining vanilla, mixing on low before briefly beating smooth. Chill for 15–20 minutes if too soft.
- Place one cool layer on a serving plate, spread with about one-third of the frosting, and add the second layer. Frost top and sides. Refrigerate for at least 30 minutes before cutting.
Notes
Times are planning estimates; use the listed doneness cues. Nutrition is an approximate ingredient-based estimate for 1 of 12 frosted slices, including walnuts.
