Preheat your oven to 350°F (175°C). Grease and flour a 10-inch Bundt pan.
Ina large bowl, whisk together the flour, brown sugar, baking powder, baking soda, cinnamon, nutmeg, and salt.
In another bowl, whisk together the vegetable oil, maple syrup, eggs, and vanilla extract until well combined.
Gradually pour the wet mixture into the dry ingredients, mixing until just combined. Be careful not to overmix.
Fold in the grated carrots and nuts until evenly distributed.
Pour the batter into the prepared Bundt pan, smoothing the top with a spatula.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for about 15-20 minutes before inverting it onto a wire rack to cool completely.
Once the cake is completely cooled, spread the Betty Crocker Cream Cheese Frosting over the top, letting it drizzle down the sides, and sprinkle with chopped pecans.
