A burst of fresh lemon and shredded zucchini combine to create this moist and tender Lemon Zucchini Coffee Cake. This all-purpose cake is delicious with scrambled eggs in the morning or a cup of tea in the afternoon.
I’ve made this Lemon Zucchini Coffee Cake three times over the course of the past month, making small tweaks each time until it was perfect.
And, it is just that. It is lemony-sweet, super moist and tender with the most perfect lemon infused crumb topping. Then, just to drive home the lemon flavor, the cake is topped with a drizzle of a simple lemon glaze.
There are three components to this recipe. The cake, the crumb topping, and a simple icing.
For the Lemon Zucchini Cake
- all-purpose flour
- baking powder (I use aluminum free)
- granulated sugar
- nonfat plain Greek yogurt
- vegetable oil
- lemons (I love to use Meyer lemons for this recipe)
- pure vanilla extract
You will need 2 lemons and definitely go with Meyer lemons if you can find them. They are dependably sweet and just fabulous in baked goods.
For the Crumb Topping
- all-purpose flour
- light brown sugar
- granulated sugar
- lemon zest
- cold butter
For the Lemon Glaze
- powdered sugar
- lemon juice
Why Use Aluminum Free Baking Powder?
If you’ve ever noticed a metallic taste in any baked good, the likely culprit is baking powder. This is especially likely to happen in recipes without strong flavors like biscuits or simply flavored cakes. Using aluminum-free baking powder is an easy way to ensure the true flavors of all of your baked goods will shine through. That being said, it is just fine to use regular baking powder in this recipe but I recommend you pick up the aluminum-free variety and give it a try. It’s only slightly more expensive and you should be able to find it at most major grocery stores. Read more on Epicurious about why aluminum-free baking powder is better.
How to Make Lemon Zucchini Cake
Gather your ingredients, shred your zucchini, and zest a couple of lemons.
- In a large mixing bowl use an electric mixer to combine sugar, yogurt, vegetable oil, eggs, lemon juice, lemon zest and vanilla extract.
- Use a wooden spoon to stir in the shredded zucchini.
- Combine the flour, baking powder, and salt in a separate bowl and add it to the wet mixture.
- Mix it until combined.
How to Make the Crumb Topping
- Place the flour, brown sugar, granulated sugar, lemon zest, salt, and butter in a small mixing bowl.
- Work the mixture with a pastry blender or fork for several minutes until the pieces of butter are pea-sized then use clean hands to work the mixture until it resembles coarse crumbs.

How to Make the Lemon Glaze
- Combine powdered sugar, milk and just enough lemon juice to reach a nice drizzling consistency.

We enjoy this Lemon Zucchini Coffee Cake at all times of the day and night. There are no rules with this one. Serve it for breakfast, with a hot cup of tea in the afternoon, or call it dessert!
It is incredible while still slightly warm but it is wonderful at any temperature.
How to Store Coffee Cake
There is no need to refrigerate this cake if you plan on consuming it within a few days. Just cover the coffee cake with a layer of plastic wrap to prevent it from drying out and let it sit on the kitchen counter. I promise, it won’t last long
But, if you have the willpower of a superhero or are just baking for one or two, cover the cake tightly with plastic wrap and pop it in the fridge to keep it fresh for a week or more. Let the cake rest at room temperature for about 15 minutes before serving or warm slices briefly in the microwave.
