Ingredients You’ll Need

• 1 ½ cups all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ¼ teaspoon salt
• ½ cup unsalted butter, softened. Let it sit out a bit unless you like wrestling with cold butter.
• 1 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• ½ cup plain yogurt or sour cream. Either works, choose your tribe.
• 1 cup grated zucchini, lightly squeezed to remove excess moisture. Don’t skip the squeeze.
• ½ cup fresh lemon juice from about 2-3 lemons. Fresh wins here.
• 1 tablespoon lemon zest. Zest is the secret party guest.
• 1 ½ cups powdered sugar
• 2-3 tablespoons milk or lemon juice. Use lemon juice for extra zing or milk if you want mellow.

Step-by-Step Instructions

1. Preheat Oven & Prepare Pan
   Preheat oven to 350°F (175°C). Lightly grease and flour a 9×13-inch baking pan, or line it with parchment paper leaving an overhang for easy removal.

2. Combine Dry Ingredients
   In a medium mixing bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt until thoroughly combined. Set aside.

3. Cream Butter and Sugar
   In a large mixing bowl, using an electric mixer, beat ½ cup softened unsalted butter with 1 cup granulated sugar on medium-high speed for 2-3 minutes until the mixture is light, fluffy, and pale.

4. Add Wet Ingredients for Bars
   Beat in 2 large eggs, one at a time, ensuring each is fully incorporated. Stir in 1 teaspoon vanilla extract, ½ cup plain yogurt or sour cream, all ½ cup fresh lemon juice, and all 1 tablespoon lemon zest. Mix on low speed until just combined.

5. Combine & Fold in Zucchini
   With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing only until just combined. Using a rubber spatula, gently fold in 1 cup grated zucchini which has been squeezed of excess moisture until evenly distributed throughout the batter.

6. Bake Bars
   Pour the batter evenly into the prepared 9×13-inch baking pan. Bake in the preheated oven for 28-35 minutes, or until the edges are golden brown and a wooden skewer or toothpick inserted into the center comes out clean or with just a few moist crumbs attached.

7. Cool Completely
   Remove the pan from the oven and place it on a wire cooling rack. It is essential to let the bars cool completely in the pan before glazing, typically 1.5 to 2 hours, or until the pan is cool to the touch.

8. Prepare Zesty Lemon Glaze
   While the bars cool, prepare the glaze. In a small mixing bowl, whisk together 1 ½ cups sifted powdered sugar with 2-3 tablespoons milk or lemon juice until completely smooth and free of lumps. Adjust the consistency with tiny additions of liquid or powdered sugar if needed aiming for a pourable but still thick glaze.

9. Glaze, Set, Cut, and Serve
   Once the zucchini bars are completely cool, pour the prepared lemon glaze evenly over them, spreading with an offset spatula. Allow the glaze to set at room temperature for about 15-30 minutes. Use a sharp knife wiped clean between cuts to cut the bars into squares or rectangles. Serve and enjoy your delicious Lemon Zucchini Bars.

10. Storage Suggestions
    Store leftover bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. If refrigerated let them come to room temperature for 15-20 minutes before serving to enhance flavors. Unglazed bars can be frozen for up to 3 months; thaw glaze and serve when ready.

11. Quick Tip Wrap Up
    Always taste your glaze while you adjust it. Too thick add a splash of liquid. Too thin add a dusting of powdered sugar. There is no shame in tasting.

Common Mistakes to Avoid

• Thinking you do not need to preheat the oven. Rookie mistake. Preheat like your baking rep depends on it.
• Skipping the squeeze on the zucchini. Wet zucchini ruins textures. Squeeze it. Seriously. Squeeze the zucchini.
• Overmixing the batter. Mix until just combined to keep the bars tender. Stop tempting fate by beating more.
• Glazing warm bars. If you glaze too soon the glaze melts into sad puddles. Wait until they cool completely.
• Using bottled lemon juice as a one to one flavor substitute. It works in a pinch but it lacks brightness. Fresh lemon gives the zing.

Alternatives & Substitutions

• Butter swap. Want dairy free? Use a firm vegan butter substitute. It changes texture slightly but still tasty. IMO use real butter when you can.
• Yogurt or sour cream. Use either. Greek yogurt works too but thin it with a splash of milk if it is super thick.
• Milk or lemon in glaze. Use milk for a milder glaze or lemon juice for extra tang. Adjust to your mood.
• Flour options. For a lighter crumb try cake flour. For gluten free use a 1 to 1 gluten free flour mix but expect a small texture shift.
• Sugar tweaks. Swap half the granulated sugar for honey or maple syrup? Not recommended for exact texture. Try small experiments if you are brave.
• Add-ins. Want herbs? A tiny bit of chopped mint or basil can be interesting. Not for the faint of heart.
