Step 1

Preheat your oven to 325°F and lightly grease a 9x13-inch baking dish.

Step 2

In a medium bowl, whisk together flour, baking powder, cinnamon, allspice, and salt.

Step 3

To a large bowl, add eggs and whisk until lightly beaten. Add sugar and vegetable oil and beat until well-mixed. Add flour mixture and use a wooden spoon to stir until just mixed.

Step 4

Add carrots and stir until evenly distributed, scraping the sides and bottom of the bowl with a rubber spatula to make sure all of the batter is mixed.

Step 5

Pour batter into prepared baking dish and smooth the top. Bake for about 50 minutes to 1 hour, until the center of the cake looks set and a toothpick or cake tester inserted into the center of the cake comes out clean.

Step 6

Cool cake in the pan until completely cool.

Step 7

In a large bowl, beat cream cheese, butter, and vanilla until well-combined and smooth. Slowly add sifted powdered sugar and beat until all the sugar is incorporated and frosting is smooth and creamy.

Step 8

Spread frosting over the top of the cake. Chill before serving if desired, and enjoy!
