Creating Carrot Cake Cream Cheese Bars is a straightforward process if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper for easy removal.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking soda, baking powder, cinnamon, nutmeg, and salt until well combined.
3. Combine Wet Ingredients: In another bowl, beat the eggs and then add the vegetable oil, grated carrots, crushed pineapple, and vanilla extract. Mix until fully combined.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients. Stir until just combined; do not overmix.
5. Pour Batter: Transfer the batter into the prepared baking pan, spreading it evenly.
6. Bake: Place in the preheated oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
7. Cool: Allow the bars to cool in the pan on a wire rack for about 20 minutes. Then, lift them out using the parchment paper and let them cool completely on the rack.
8. Prepare Frosting: In a mixing bowl, beat the softened cream cheese and butter until smooth. Gradually add the powdered sugar and milk, mixing until creamy. Finally, stir in the vanilla extract.
9. Frost the Bars: Once the bars are completely cooled, spread the cream cheese frosting evenly over the top.
10. Slice and Serve: Cut into squares and serve. Enjoy the deliciousness of your Carrot Cake Cream Cheese Bars!
