1 1/2 teaspoons ground cinnamon
•
1/2 teaspoon ground allspice
•
1/2 teaspoon ground nutmeg
•
1/2 teaspoon salt
•
1 cup firmly packed dark brown sugar
•
4 eggs, at room temperature
•
1 1/2 teaspoons vanilla extract
•
3 cups shredded carrots
•
1/2 cup chopped walnuts
•

3 cups powdered sugar

Directions
1
Place butter in a light-colored saucepan over medium heat. Cook, swirling the pan constantly, until butter is bubbling, smells nutty, and browned bits begin to form on the bottom of the pan, 5 to 10 minutes. Immediately remove from heat and pour butter into a heat-safe bowl. Allow brown butter to cool to room temperature, about 15 minutes.
2
Preheat the oven to 325 degrees F (165 degrees C). Grease a 12x16-inch pan and line with parchment paper.
3
Whisk flour, baking soda, baking powder, cinnamon, allspice, nutmeg, and salt together in a bowl until well combined.
4
Beat cooled brown butter and brown sugar in a large bowl with an electric mixer on medium speed until well combined. Beat in eggs, one at a time, mixing well after each addition, until mixture is light and fluffy. Mix in vanilla. Pour in 1/2 of the flour mixture and mix until just combined. Add in remaining flour mixture and mix until just combined.
5
Fold in shredded carrots, walnuts, and raisins. Pour batter into the prepared pan and smooth out the top with a spatula.
6
Bake in the preheated oven until cake is golden and a toothpick inserted into the center of it comes out clean, 23 to 27 minutes. Transfer onto a wire rack and cool completely, about 30 minutes.
7
While cake is cooling, repeat step 1 to brown butter for the frosting. Let cool to room temperature, about 15 minutes.
8
Beat cream cheese in a large bowl with an electric mixer on medium-high speed until completely smooth. Add in cooled brown butter and mix until thoroughly combined. Mix in powdered sugar, 1 cup at a time, beating well after each addition. Mix in vanilla and salt. Beat frosting at medium-high speed until completely smooth, 1 to 2 minutes.
9
Spread frosting over the cooled cake. Chill cake until ready to serve.
