Cinnamon swirl zucchini cake is an easy summer recipe. Bake this cake in a loaf pan and top with cinnamon icing for extra sweetness.
It’s that time of year again where zucchini is abundant in the vegetable garden. I took advantage of the surplus of squash and baked cinnamon swirl zucchini cake.
This cake is soft, moist and filled with a cinnamon swirl. The cake loaf is topped with a cinnamon glaze, which adds just the right amount of sweetness. You could eat this cake for dessert or breakfast if you ask me!
Why zucchini makes cake moist
Zucchini, like many vegetables, is mostly water. The green squash is actually 90% water! The other 10% consists of carbohydrates, sugar, a little protein and minerals.
The water content makes zucchini an excellent ingredient for breads and cakes. It naturally makes the baked goods extra moist without weighing it down too much. Zucchini also doesn’t have much flavor, which makes it a versatile ingredient.
To keep the moisture in the zucchini, shred the squash right before adding it to the batter. The vegetable will begin to dry out as soon as you cut it open. Keep the water content in the vegetable as long as possible so it evaporates into the cake during the baking process.
Zucchini loaf cake recipe steps
Making a loaf of zucchini cake is rather easy. Mix the dry ingredients together in one bowl. Then mix the wet ingredients in another. Combine the two together and stir just until combined.
Add the shredded zucchini last so the moisture remains in the squash and can evaporate during the baking process. Always mix just until combined and avoid over mixing. Mixing too much will create a tough, dense cake.
What makes this zucchini cake special is the cinnamon sugar swirl.
Cinnamon swirl in cakes
Cinnamon swirl is a visual and tasteful surprise in cakes. It is rather simple to do too!
In a small bowl combine cinnamon and granulated sugar. I find that 1 1/2 teaspoons cinnamon and 3 tablespoons sugar is a good ratio. If you run out, you can always make more!
Layer half the cake batter in the pan, then sprinkle the cinnamon sugar evenly on top. Finish by pouring the remaining cake batter on top of the cinnamon sugar. That’s all it takes!
