How To Make Carrot Cake Sheet Cake
Preheat your oven to 350°F (180°C). Grease a 9×13 inch baking pan and set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely.
To make the frosting, beat together the cream cheese and butter until smooth. Add the confectioners’ sugar and vanilla and beat until well combined and smooth. Spread the frosting over the cooled cake and serve.
