Zesty Lemon Zucchini Muffins

Why This Zesty Lemon Zucchini Muffins Works

In the oven, the batter slowly sets around the shredded zucchini. The zucchini holds a lot of water, so as it heats up, that moisture steams inside the muffin instead of drying it out. The flour, egg, and melted butter firm up around those little bits of zucchini, so the muffins stay soft and moist instead of soggy.

As the baking powder and baking soda warm, they create tiny air pockets in the batter. Those bubbles get trapped by the egg and flour, so the muffins rise and stay light instead of dense. Sugar melts into the batter and keeps the crumb tender, while the melted butter spreads evenly so there are no dry spots.

During baking, the lemon juice and zest spread through the whole muffin. The heat softens the sharp taste of the lemon so it tastes bright but not harsh. If walnuts are used, they toast slightly in the oven, staying firm while the rest of the muffin stays soft, giving a nice contrast in each bite.

Mistakes To Avoid

Overbaking these muffins easily dries them out. Once they go past the 20-minute mark, the edges start to harden and the crumb loses its soft, moist feel, so the muffins end up crumbly instead of tender.

Skipping the step of squeezing excess water from the shredded zucchini leaves too much liquid in the batter. During baking, that extra moisture keeps the center from setting properly, so the muffins can sink in the middle and feel gummy instead of fluffy.

Pouring very hot melted butter straight into the egg mixture can partially cook the egg. This creates little rubbery bits in the batter and stops everything from mixing smoothly, which leads to uneven texture in the baked muffins.

Overmixing the batter after combining wet and dry ingredients makes the muffins dense. The more the flour is worked, the tighter the crumb becomes, so instead of light, soft muffins, they bake up heavy and tough.
