Preheat the oven to 350ºF. Spray a 8x8" square baking pan with cooking spray. Line with parchment paper for easy removal if you'd like.
In a medium size bowl, use a hand mixer to mix the dry cake mix, egg, melted butter and zucchini until well combined. The batter will be very thick. 1 box spice cake mix, 1 large egg, 1/4 cup salted butter, 1 cup shredded zucchini
Press the mixture into the prepared pan and bake for 25 minutes.
Once the bars are cool, frost the bars with cream cheese frosting. Then drizzle with caramel and sprinkle with walnuts. 12 ounces cream cheese frosting, 3 tablespoons caramel sauce, 1/4 cup chopped walnuts
Notes
Use any flavor cake mix you'd like.
I used a box grater to grate the zucchini. A food processor works too.
We like these bars best when the are cold, so we store them in the fridge. They do not have to be stored in the fridge, but should be stored in an airtight container.
Refer to the article above for more tips and tricks.The calories shown are based on the bars being cut into 12 pieces, with 1 serving being 1 bar.
