In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. The mix of cinnamon and nutmeg creates that perfect warm spiced base that’s so comforting in this cake.
In a separate bowl, beat the eggs, oil, sugar, and vanilla until smooth and combined. This will form the base of your moist cake.
Gradually fold the wet ingredients into the dry ingredients, making sure everything is well incorporated. Then, add the grated carrots, pineapple, and chopped walnuts. Stir gently until fully combined, making sure you don’t overmix.
