1-First, preheat your oven to 350°F (175°C) and spray a 9 x 9-inch baking dish with cooking spray to prevent sticking. This ensures your bars come out cleanly and maintain their shape.

2-In a large bowl, whisk together the oil, granulated sugar, and brown sugar until smooth and well combined. Then, add the eggs and vanilla extract, whisking everything together to create a creamy mixture. This step builds the base flavor for your carrot cake bars recipe with cream cheese frosting.

3-Mixing and Baking the Batter: Next, in a separate bowl, mix the flour, cinnamon, baking soda, salt, baking powder, nutmeg, and cloves until evenly distributed. Gradually add these dry ingredients into the wet mixture, stirring gently until smooth. Fold in the grated carrots and any optional add-ins like nuts or raisins for extra texture.

4-Pour the batter into your prepared baking dish, spreading it evenly for uniform baking. Pop it into the oven and bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on it to avoid overbaking, which helps keep that moist texture.

5-Once baked, let the bars cool to room temperature on a wire rack. While they cool, prepare the frosting by combining the cream cheese, butter, and vanilla until smooth, then gradually stir in the powdered sugar until it reaches your preferred thickness.

6-Spread the frosting evenly over the cooled bars, slice them up, and serve. This step ensures the frosting doesn’t melt, giving you perfect, professional-looking treats. Baking times may vary, so check early for the best results!
