Instructions

Step 1: Preheat and prepare the pan

Preheat the oven to 350°F (175°C). Grease and lightly flour a 9x9 inch metal baking pan so it’s ready to receive the batter; set the greased pan to one side on the painted white pine surface. Keep a clean, matte-grey mixing bowl and a silicone spatula nearby for continuity as you move through the steps.

Step 2: Combine the dry spices and leaveners

In a medium bowl whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, ground nutmeg, and salt until evenly distributed and aromatic. This creates a fine, speckled dry mix where the warm spice flecks are suspended in the pale flour.

Step 3: Cream the sugars with the oil

In the matte grey mixing bowl beat the granulated sugar and packed brown sugar with the vegetable oil until the mixture is glossy and homogeneous, the sugars mostly dissolved into the oil to form a smooth, amber-tinted base.

Step 4: Incorporate the eggs

Add the eggs one at a time to the wet mixture, beating well after each addition so the batter becomes cohesive and slightly thickened, with a satiny sheen gradually developing.

Step 5: Add the vanilla

Stir vanilla extract into the wet mixture, folding it in gently to perfume the batter and deepen the overall sweetness profile.

Step 6: Bring wet and dry together

Gradually add the dry spiced flour mixture into the wet mixture, mixing just until combined; stop when there are no visible streaks of flour. The batter should be thick but spreadable, flecked with tiny brown spice granules.

Step 7: Fold in carrots and nuts

Fold in the grated carrots and the chopped walnuts (if using) with a spatula, taking care to keep the batter airy while ensuring the bright orange shreds and small nut fragments are evenly distributed throughout.

Step 8: Transfer and smooth the batter into the pan

Pour the batter into the prepared 9x9 pan and spread it evenly with a spatula until the surface is level and textured with small peaks from the spreading motion.


Step 9: Bake until set

Bake the pan for 30–35 minutes, or until a toothpick inserted in the center comes out clean and the top has turned a warm golden-brown. Allow the heat to pull the color into the edges, creating an even, slightly risen surface.

Step 10: Cool completely

Remove the pan from the baking area and allow the cake to cool completely in the pan on the white painted surface so the crumb firms up and the pan is cool enough to frost without melting the topping.

Step 11: Whip the frosting base

In a small bowl beat together the softened cream cheese and softened butter until utterly smooth and lump-free, a pale, velvety base ready to be sweetened.

Step 12: Sweeten the frosting

Gradually add the powdered sugar and vanilla extract to the cream cheese mixture, beating until creamy and pipeable—thick enough to hold a decorative swirl but still yielding when spread.

Step 13: Frost the cooled bars

Spread the frosting evenly over the cooled sheet of cake in the same square pan, smoothing to the edges and optionally piping gentle swirls. Sprinkle the top with finely chopped walnuts to provide a contrasting crunch and warm, nutty note.

Step 14: Cut and serve

Using a clean knife, cut the frosted sheet into neat rectangular bars within the pan and serve directly from the square pan or slide individual bars onto a plate. Enjoy the moist, spiced interior contrasted with the cool, creamy frosting.
