These 4 ingredient Carrot Cake Bars are made from a cake mix! They're good enough without frosting, but for a special treat top them with cream cheese frosting.
Preheat oven to 350ºF. Spray an 8x8" baking pan with cooking spray.
In a small bowl, mix together the dry cake mix, cream cheese, egg and butter until completely mixed. The dough will be very thick. 1 box Betty Crocker carrot cake cake mix, 4 ounces cream cheese, 1 large egg, 1/4 cup salted butter
Press the dough into the prepared pan. Bake for 14-18 minutes. Remove from the oven and allow the bars to cool.
For homemade frosting: Using an electric mixer, mix the butter and cream cheese, scraping down the sides as needed, until the mixture is light and fluffy. This will take about 5 minutes. With the mixer on low speed, add the powdered sugar, 1/2 a cup at at time, until it is thoroughly mixed. Add the vanilla and beat the frosting on medium speed for about 3 minutes. 4 ounces cream cheese, 6 tablespoons salted butter, 1 3/4 cups powdered sugar, 1/2 tablespoon vanilla extract
Frost the carrot cake bars with the frosting and top with the chopped walnuts. 1/2 cup chopped walnuts
Notes
We baked our bars for 14 minutes exactly and thought the texture was perfect (very soft). If you want them just a bit "cakey-er" or if your bars seem too "raw" for your liking, let them bake an additional 3-4 minutes.Store these covered at room temperature for up to 2 days or refrigerate for up to 5 days.They also freeze well. Slice first, then freeze for easy grab-and-go portions.
