Ingredients You’ll Need
What you’ll love most about these Delicious Lemon Zucchini Bars with Glaze is just how straightforward the shopping list is. Each ingredient does double duty: building flavor while ensuring fantastically tender bars and a glaze that dazzles.
- All-purpose flour: Provides the perfect structure for bars that are soft but never soggy.
- Baking powder: Gives these bars a nice gentle lift so they’re tender and light.
- Baking soda: Balances out the acidity of the lemon, helping the bars rise evenly.
- Salt: Just a pinch sharpens all those fresh, zesty flavors.
- Unsalted butter, softened: Ensures richness and a melt-in-your-mouth crumb—let it come to room temperature for easy mixing.
- Granulated sugar: Sweetens the bars without overpowering the lemon; it also helps lock in moisture.
- Large eggs: Help bind everything together for a perfect, cohesive bar.
- Vanilla extract: Adds warmth and subtle complexity that lets the lemon shine even brighter.
- Plain yogurt or sour cream: Keeps the bars ultra-moist and tangy; use what’s in your fridge!
- Grated zucchini, lightly squeezed: The secret to exceptional moisture and a hint of garden-fresh flavor (no one will guess what’s in there).
- Fresh lemon juice (from about 2-3 lemons): Use freshly squeezed juice for vibrant, true lemon flavor.
- Lemon zest: Intensifies the citrus notes for a joyful burst of sunshine in every bite.
- Powdered sugar: The foundation of a heavenly lemon glaze you’ll want to drizzle on everything.
- Milk or lemon juice (for the glaze): Whisk with powdered sugar for a thick but pourable finish (lemon juice gives the ultimate zing!).
How to Make Delicious Lemon Zucchini Bars with Glaze
Step 1: Prep Your Pan and Oven
First things first: preheat your oven to 350°F (175°C) and grease and flour an 8×8 inch baking pan. Taking a moment to prepare your pan well ensures these bars pop out perfectly with those gorgeous golden edges everyone loves.
Step 2: Whisk the Dry Ingredients
Grab a medium bowl and whisk together the flour, baking powder, baking soda, and salt. This guarantees every bite is thoroughly mixed and delightfully fluffy—no weird dry patches.
Step 3: Cream Butter and Sugar
In a large bowl, cream your softened butter and granulated sugar until it’s light and fluffy. Don’t rush this step! You want to achieve that creamy, cloud-like texture that leads to supremely tender bars.
Step 4: Add Eggs and Vanilla
Beat in your eggs, one at a time, then stir in the vanilla extract. Mixing slowly and carefully keeps everything well-incorporated and helps create a blissfully smooth batter base.
Step 5: Combine Yogurt and Lemon Juice
In a small bowl, whisk together your yogurt (or sour cream) with the fresh lemon juice. This mixture not only adds a tangy punch but also keeps your bars incredibly moist.
Step 6: Mix Wet and Dry Ingredients
Alternately add your whisked dry ingredients and the tangy yogurt mixture to the creamed wet ingredients, starting and ending with the dry. Mix gently until just combined—overmixing here is the enemy of tender bars!
Step 7: Fold in Zucchini and Lemon Zest
Now for the fun part: gently fold in your grated, squeezed zucchini and all that lively lemon zest. Your batter will smell amazing and will be flecked with bits of fresh green and bright yellow—a real preview of the finished treat.
Step 8: Pour and Bake
Pour the batter into your prepared pan, smoothing it into an even layer. Bake for 30-35 minutes, or until a toothpick comes out clean and the top is lightly golden. The hardest part? Waiting as your kitchen fills with irresistible lemony aroma!
Step 9: Cooling Down
Let the bars cool in the pan for 15-20 minutes before transferring them to a wire rack. This little pause ensures they finish setting up and turn out with the perfect chewy, fudgy edge.
Step 10: Glazing Time
As the bars cool completely, whisk together the powdered sugar and your choice of milk or lemon juice. Aim for a smooth, pourable glaze that will drape beautifully over the bars—using lemon juice here guarantees a bold, citrusy finish!
Step 11: Drizzle and Set
Once the bars are totally cool, generously drizzle the glaze over the top. Let the glaze hang out and set—this is when the bars become truly irresistible, with a glossy, sweet-tart finishing touch.
Step 12: Slice and Enjoy
When the glaze is set, cut your Delicious Lemon Zucchini Bars with Glaze into squares and get ready to watch them disappear faster than you thought possible!
How to Serve Delicious Lemon Zucchini Bars with Glaze

Garnishes
A sprinkle of extra lemon zest adds a sunny pop of color and intensifies that citrusy perfume. You can also try a dusting of powdered sugar or a scattering of edible flowers for an elegant, garden-inspired finish that makes these bars truly irresistible.
Side Dishes
Pair your Delicious Lemon Zucchini Bars with Glaze with a bowl of fresh berries, a scoop of vanilla ice cream, or a refreshing glass of lemonade. Each option brings out the summery vibe and balances the tangy sweetness with extra freshness or creaminess.
Creative Ways to Present
Serve these bars on a cheerful platter lined with lemon slices or tuck them into cupcake wrappers for an easy-to-grab party treat. For special occasions, stack the bars and tie with baker’s twine for an adorable edible gift—no one can resist a stack of citrusy goodness!
Make Ahead and Storage
Storing Leftovers
Store leftover bars in an airtight container at room temperature for up to 2 days. For slightly longer freshness, refrigerate them—just let the bars come up to room temperature before serving, so the texture stays dreamy and soft.
Freezing
You can absolutely freeze Delicious Lemon Zucchini Bars with Glaze! Freeze unglazed bars wrapped tightly in plastic and foil for up to 2 months; thaw overnight in the fridge and glaze once thawed for the best texture and freshest lemon punch.
Reheating
While these bars are best served at room temperature, if you crave a warm treat, pop a bar in the microwave for 10-15 seconds. The glaze will become a little gooey, adding an extra level of decadence—just keep a napkin handy!
FAQs
Can I use yellow squash instead of zucchini?
Absolutely! Yellow squash works beautifully in place of zucchini—it adds the same subtle flavor and moisture while blending right in with the lemony goodness.
Do I have to squeeze the zucchini before adding it?
Yes, giving the grated zucchini a light squeeze removes excess moisture and helps the bars bake up perfectly tender (not soggy). Just use a clean kitchen towel or paper towels to gently press out some water.
Can I make these bars gluten-free?
Definitely! Just substitute your favorite 1-to-1 gluten-free flour blend for the all-purpose flour. The bars will be just as moist and flavorful—no one will notice the difference.
What if I don’t have fresh lemons?
While fresh lemons provide the brightest flavor, you can use bottled lemon juice in a pinch. For the zest, try a small amount of lemon extract if you have it, or simply double down on the juice for a strong citrus punch.
Can I double the recipe for a crowd?
Yes! This recipe doubles easily. Use a 9×13 inch pan and be sure to watch the baking time—start checking around 30-35 minutes and look for that clean toothpick in the center.

Every time I bake Delicious Lemon Zucchini Bars with Glaze, they bring big smiles and sunny vibes to the table.
