How to Make Lemon Zucchini Bars (Step-by-Step Instructions)

These bars are simple to prepare and come together in just one bowl. Here’s how to make them:

Step 1: Prep Your Ingredients

Preheat your oven to 350°F (175°C) and grease or line an 8×8-inch baking pan with parchment paper. Grate the zucchini and gently blot it with a paper towel to remove excess moisture.

Step 2: Mix the Batter

In a large bowl, whisk together the egg, sugar, melted butter, Greek yogurt, lemon juice, and lemon zest. Stir in the grated zucchini.

Add the flour, baking powder, baking soda, and salt. Mix just until combined—don’t overmix.

Step 3: Bake

Pour the batter into your prepared pan and smooth out the top. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let the bars cool completely in the pan.

Step 4: Glaze and Serve

Once the bars are cool, whisk together the glaze ingredients until smooth. Drizzle over the bars and spread with a spoon. Let set for 10 minutes before slicing.

Bonus Tip: Serve these bars with a scoop of vanilla yogurt or fresh berries for an even fancier presentation.

• Use fresh lemon: Bottled juice won’t give you the same zesty flavor.
• Let the bars cool before glazing: This keeps the glaze from soaking in too much and disappearing.
• Store in the fridge: These bars stay freshest when kept chilled.
