Zucchini bars with cream cheese frosting are a moist, flavorful treat that balances the subtle earthiness of zucchini with the rich tang of sweet frosting. These bars are perfect for using up summer squash and make a delicious, tender dessert or snack that feels indulgent without being overly heavy.
Ingredients
- 2 cups grated zucchini (about 2 medium zucchinis, squeezed dry)
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 3/4 cup granulated sugar
- 1/2 cup brown sugar, packed
- 3 large eggs
- 1 cup vegetable oil (or canola oil)
- 2 teaspoons vanilla extract
- 1/2 cup chopped walnuts or pecans (optional)
For the Cream Cheese Frosting
- 8 ounces cream cheese, softened
- 1/4 cup unsalted butter, softened
- 2 cups powdered sugar, sifted
- 1 teaspoon vanilla extract
- 1-2 tablespoons milk or heavy cream (optional, for consistency)
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easier removal.
- Grate the zucchini using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel or paper towels and gently squeeze out excess moisture. This prevents soggy bars.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly combined.
- In a large mixing bowl, beat the granulated sugar, brown sugar, and eggs together until smooth and slightly fluffy—about 2-3 minutes.
- Slowly add the vegetable oil and vanilla extract to the egg mixture, mixing until fully incorporated.
- Fold the dry ingredients into the wet ingredients gently, just until combined. Avoid overmixing to keep the bars tender.
- Fold in the grated zucchini and nuts (if using) until evenly distributed throughout the batter.
- Pour the batter into the prepared baking pan and spread it out evenly with a spatula.
- Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- Remove from oven and allow the bars to cool completely in the pan on a wire rack before frosting.
- To prepare the cream cheese frosting, beat the softened cream cheese and butter together until smooth and creamy.
- Add the powdered sugar and vanilla extract, then beat until fluffy. Add milk or heavy cream a little at a time if you want a thinner consistency.
- Spread the frosting evenly over the cooled zucchini bars. Slice into squares and serve.
Tips
- Dry your zucchini well: Removing excess moisture is key to preventing soggy bars. Use a towel or cheesecloth to squeeze out as much water as possible.
- Substitute oils: You can use melted coconut oil or light olive oil instead of vegetable oil for a different flavor profile.
- Storage: Keep frosted bars refrigerated in an airtight container for up to 4 days. The frosting contains cream cheese and can spoil if left out too long.
- Don’t overmix the batter: Mixing too much can develop gluten and make the bars dense rather than tender.
Serving Suggestions
- Serve chilled or at room temperature with a hot cup of coffee or tea for a delightful afternoon snack.
- These bars also pair well with fresh berries or a drizzle of honey for extra sweetness.
- For a festive touch, sprinkle chopped nuts or a dusting of cinnamon on top of the cream cheese frosting before serving.
- You can also cut the bars into smaller bite-sized pieces for parties or potlucks.
Variations
- Chocolate Zucchini Bars: Add 1/2 cup cocoa powder to the dry ingredients and reduce flour by 1/2 cup. You can also mix mini chocolate chips into the batter.
- Lemon Cream Cheese Frosting: Add 1 tablespoon of fresh lemon juice and 1 teaspoon lemon zest to the frosting for a bright, citrusy twist.
- Spiced Zucchini Bars: Increase cinnamon to 2 teaspoons and add 1/2 teaspoon ground cloves or ginger for a warm, spiced flavor.
- Nut-Free Version: Simply omit the nuts or substitute with seeds like pumpkin or sunflower seeds for crunch.
Storage and Reheating
Store zucchini bars with cream cheese frosting in an airtight container in the refrigerator for up to 4 days. The frosting’s dairy content requires refrigeration to keep it fresh and safe. If you want to store the bars longer without frosting, wrap them tightly and freeze for up to 3 months.
To reheat, remove the frosting if frozen and warm the bars gently in the microwave for 15-20 seconds or in a low oven (300°F / 150°C) for about 10 minutes, then reapply fresh frosting if desired. Avoid reheating frosted bars directly, as the frosting can melt and separate.
Frequently Asked Questions
Can I use yellow squash instead of zucchini?
Yes, yellow squash works well as a substitute in this recipe. It has a similar moisture content and mild flavor, so you can use it in equal amounts without adjusting other ingredients.
Do I need to peel the zucchini before grating?
No, peeling isn’t necessary. The skin adds color, texture, and nutrients. Just make sure to wash the zucchini thoroughly before grating.
How can I tell when the bars are done baking?
Insert a toothpick or cake tester into the center of the bars. If it comes out clean or with a few moist crumbs, the bars are done. Avoid overbaking, or the bars may dry out.
Can I make these bars gluten-free?
Yes, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. The texture may be slightly different but still delicious.
Is it necessary to refrigerate the bars after frosting?
Because the frosting contains cream cheese and butter, refrigeration is important to prevent spoilage and maintain freshness. Leave them out no longer than 2 hours at room temperature.
Can I prepare the bars in advance?
Absolutely! You can bake the bars a day ahead and refrigerate them unfrosted. Apply the cream cheese frosting just before serving for the best texture and appearance.
Zucchini bars with cream cheese frosting are a wonderful way to enjoy a moist, lightly spiced dessert that’s perfect year-round. With simple ingredients and easy steps, they offer a healthy twist on traditional bars, making them a crowd-pleaser at any gathering.
