This incredibly easy Small Carrot Cake With Cream Cheese Frosting is a perfect replica of my mom's potluck favorite!
Preheat your oven to 350°F. Lightly grease your baking dish.
In a small bowl, whisk together flour, baking soda, cinnamon, allspice, and salt.
In a medium bowl, whisk together sugar, vegetable oil, and egg until well combined. Stir in flour mixture and use a rubber spatula to fold in grated carrots. Transfer batter to prepared baking dish.
Bake for 25 to 30 minutes, until a toothpick inserted into the center of the cake comes out clean. Place cake (in pan) on a cooling rack, and cool completely before frosting, about 45 minutes.
Whisk together cream cheese, butter, and vanilla until smooth. Add sifted powdered sugar and salt and whisk until well-combined and fluffy. Spread frosting over the cake. Chilling before serving is optional but recommended. Serve cake in the baking dish and store covered in the refrigerator.
