Moist Zucchini Cake with Silky Chocolate Glaze

This zucchini cake is simple summer baking elevated by a glossy, silky chocolate glaze. Moist, tender, and easy to make, it turns an abundance of garden zucchini into an elegant loaf that’s perfect for coffee or dessert.

Vegetable-forward cakes are some of my favorites — they add natural moisture and subtle sweetness. Zucchini works beautifully here, much like other favorites such as butternut squash or classic carrot cake. When summer yields too many squash to count, this cake is the perfect solution.

Recipe highlights

• Ultra moist zucchini cake. Shredded zucchini, melted butter, and whole-milk yogurt all contribute to a tender, moist loaf.
• Shiny chocolate glaze. A glossy chocolate-honey glaze makes the cake feel just a bit more refined.
• Easy yet elegant. Minimal effort yields a loaf that looks and tastes special — ideal for lazy summer baking.

Tips for making this cake

This recipe is straightforward, but a few small steps make a big difference.

Measure the shredded zucchini. Zucchini vary in size. Aim for about three cups of shredded zucchini rather than relying on a specific number of squash.

Squeeze out excess moisture. Zucchini holds a lot of water. After shredding, wrap the zucchini in cheesecloth or paper towels and squeeze firmly to remove extra liquid so your batter won’t be too wet.

Don’t overmix. Fold the dry ingredients into the wet mixture gently until no streaks of flour remain to keep the crumb tender.

Add chocolate. Mini chocolate chips are optional but add a delightful burst of chocolate in every bite.

Check doneness by temperature. For loaf cakes, an accurate internal temperature is a reliable indicator: the center should reach about 200–205° F.

Cool before glazing. Let the cake cool completely before pouring the glaze so it sets properly and doesn’t run off.

Chocolate glaze tips

Chop the chocolate finely. Small pieces melt more quickly and evenly when combined with hot cream.

Do not overheat the cream. Heat the cream until tiny bubbles form around the edges but avoid a full boil — overheating can make the glaze separate or become grainy.

Drizzle while warm. Pour the glaze while it’s still warm so it flows smoothly and drips over the sides.

Let it set. For the best texture, allow the glaze to firm up for about an hour before slicing.

Substitutions & variations

You can bake this in a standard 9×5 loaf pan, or use an 8-inch square pan or a 9-inch round — just watch the bake time and use a thermometer to check doneness.

Ingredient swaps that work well:

• Whole milk yogurt — substitute sour cream.
• Mini chocolate chips — omit or use chunks of dark, milk, or semisweet chocolate.
• Coconut oil — swap in avocado oil if preferred.

Alternative frostings/glazes

If you’d prefer a different finish, cream cheese icing, salted ganache, or a bright lemon glaze would all pair nicely. If using a citrus glaze, consider leaving out the chocolate chips to keep the flavor balanced.
