- 🥄 1 teaspoon baking powder

How to Make Lemon Zucchini Bars with Glaze
Prep: Preheat oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish (or line with parchment). Squeeze grated zucchini well in a clean towel to remove as much water as possible – this is key for perfect texture!
- Cream butter & sugar: In a large bowl, beat softened butter and granulated sugar together until light and fluffy (about 2 minutes).
- Add wet ingredients: Whisk in eggs, lemon juice, lemon zest, and vanilla extract. The mixture will look glossy and smell divine.
- Mix dry ingredients: In a separate bowl, combine flour, baking powder, baking soda, and salt.
- Combine gently: Gradually stir the dry mixture into the wet mixture until just combined. Do not overmix – a few flour streaks are okay.
- Fold in zucchini: Gently fold the squeezed, grated zucchini into the batter until evenly distributed.
- Bake: Pour batter into prepared dish, spread evenly. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean (a few moist crumbs are fine). Cool completely in the pan on a wire rack.
- Make glaze: In a small bowl, whisk powdered sugar and milk until smooth. If too thick, add a drop more milk; if too thin, add a pinch more sugar.
- Drizzle & garnish: Pour or drizzle glaze over cooled bars. Sprinkle extra lemon zest on top if desired. Let glaze set for 10–15 minutes, then slice into 9 (or 16) squares.
How to Serve & Dress Up Your Bars
These Lemon Zucchini Bars with Glaze are incredibly versatile. Serve them plain for a simple afternoon pick-me-up, or level them up in these fun ways:
- 🍦 À la mode: Top a warm bar with a scoop of vanilla bean ice cream and a drizzle of honey.
- 🍓 Berry beautiful: Add fresh raspberries or blueberries on top just before the glaze sets – a pop of color and tartness.
- 🌿 Herb twist: Mix a little chopped mint or basil into the glaze for a garden-fresh finish.
- 🍰 Layer it: Cut bars into small cubes and layer with lemon curd and whipped cream in a trifle dish.
- 🎉 Party platter: Cut into tiny bite-sized squares and serve on a dessert board with cookies, fruit, and chocolate.
Best served at room temperature or slightly chilled. They pair beautifully with iced tea, lemonade, or a fruity white wine spritzer.
Storage & Shelf Life
Store your Lemon Zucchini Bars with Glaze in an airtight container in the refrigerator. The glaze helps seal in moisture, so they stay soft for up to 5 days. For longer storage, freeze the unglazed bars (wrap individually in plastic wrap and place in a freezer bag) for up to 3 months. Thaw in the fridge overnight, then glaze fresh before serving. If glazed already, you can still freeze but the glaze may lose its shine – still delicious, though!
Frequently Asked Questions
Yes! Substitute up to half the flour with whole wheat. The bars will be a bit denser but still tasty. For best texture, use white whole wheat flour.
No need! The green skin adds flecks of color and extra nutrients. Just wash it well and grate (large holes work best).
Use a clean kitchen towel, place grated zucchini in center, gather corners, and twist hard over the sink. You can also press through a fine-mesh strainer with a spatula.
Absolutely! Use vegan butter or coconut oil (solid) instead of butter, and swap milk in the glaze with almond, oat, or soy milk. The texture may vary slightly but will be delicious.
Most likely the zucchini wasn’t squeezed dry enough. Always remove as much liquid as possible. Also check your baking time – ovens vary, so bake until truly set in the middle.
Yes, the bars are lovely without glaze! They’re less sweet but still lemony and moist. Dust with powdered sugar instead if you want a lighter finish.
Fresh lime juice works beautifully for a lime version. You can also use bottled lemon juice, but fresh gives the best zing.
Yes! Fold in 1 tablespoon poppy seeds for lemon-poppy bars, or ¼ cup unsweetened shredded coconut for tropical vibes.
If you cut into 16 smaller squares, each will be about 144 kcal. Perfect for bite-sized treats!
Glaze consistency varies with humidity and sugar lumpiness. Adjust by adding milk a drop at a time to thin, or more powdered sugar to thicken. Aim for a pourable but not watery consistency.
✨ Enjoy your Lemon Zucchini Bars with Glaze – the dessert that hides a veggie, delivers pure citrus joy, and makes everyone ask for the recipe!
