How to make Iced Cinnamon Zucchini Bars
Prep
Get started by spraying a 10×15 jelly roll pan with non-stick spray and set it aside. Then preheat the oven to 350°F.
Also prepare the zucchini for the batter. Use a cheese grater and grate to obtain the required amount, squeeze extra liquid out using a paper towel.
Batter
Next, in a medium sized mixing bowl cream the butter and sugars using an electric mixer. Then add the eggs and vanilla extract; beat again until combined.
In a separate bowl, whisk the flour, baking powder, and salt. Proceed to gradually stir the dry mixture into the butter mixture.
Now stir in the shredded zucchini, coconut flakes, and 2/3 cup of the walnuts.
Bake
Spread the batter on the prepared pan and place in the preheated oven to bake for 25-30 minutes. Or until a toothpick inserted near the center comes out clean.
Icing
For the icing, combine the powder sugar, cinnamon, butter, vanilla extract, and milk. Whisk well until lump free and smooth. Continue to drizzle the icing over the cooled cake and top with the remaining nuts.
Cut into squares, serve & enjoy!

Variations and Substitutions for Zucchini Bread Bars
For those who want to switch things up, there are a few variations and substitutions that can be made to this recipe. Here are a few options to consider:
- Flour: While the recipe calls for all-purpose flour, it can be substituted with whole wheat flour or almond flour for a healthier twist. Keep in mind that the texture and taste of the bars may differ slightly with these substitutions.
- Spices: Cinnamon is the star of the show in this recipe, but other spices such as nutmeg, ginger, or cardamom can be added for a different flavor profile. Be sure to adjust the measurements accordingly to avoid overpowering the dish.
- Sweeteners: Instead of using granulated sugar, try using honey, maple syrup, or coconut sugar for a natural alternative. Keep in mind that these sweeteners may affect the texture and moisture of the bars.
- Zucchini: If you don’t have zucchini on hand, shredded carrots or apples can be used instead. This will alter the flavor slightly, but still provide a moist and delicious texture.

How long are Iced Zucchini Bread Bars good for?
These zucchini bars should be stored in an airtight container, at room temperature, and they will last for up to 5 days. For longer storage, they can be refrigerated for up to a week or frozen for up to 3 months. It is important to let the cake cool completely before storing it to prevent condensation from forming and making the cake soggy.

Health Benefits of Iced Zucchini Bars
Zucchini is a low-calorie vegetable that is high in fiber, vitamins, and minerals. It contains antioxidants that help to reduce inflammation and improve heart health. Cinnamon is also high in antioxidants and has been shown to improve blood sugar control and reduce the risk of heart disease.
How do I modify the baking time when using frozen zucchini?
If using frozen zucchini instead of fresh, it is important to thaw and drain it before adding it to the batter. The baking time may need to be adjusted slightly depending on the moisture content of the zucchini. It is recommended to bake the bars for the minimum time listed in the recipe and then check for doneness by inserting a toothpick into the center. If it comes out clean, the bars are done. If not, continue baking in 5-minute increments until done.
Can the moisture content of frozen zucchini affect the texture of the bars?
Yes, the moisture content of frozen zucchini can affect the texture of the bars. If the zucchini is not properly drained, it can make the bars too moist and dense. It is important to thaw and drain the zucchini well before adding it to the batter. If the zucchini still seems too wet, it can be squeezed in a clean kitchen towel to remove excess moisture.

Tips for ensuring even distribution of zucchini in the batter
To ensure even distribution of zucchini in the batter, it is recommended to grate the zucchini finely and then stir it into the batter until just combined. Overmixing can lead to uneven distribution and a dense texture. It is also important to measure the grated zucchini accurately to ensure that the recipe turns out correctly.
