  • 250g pack of unsalted butter, very soft, plus some butter for the tin
  • 3 unwaxed lemons
  • 200g golden powdered sugar
  • 3 eggs
  • 2 medium zucchini, coarsely grated (you need 300g pulp)
  • 1 teaspoon poppy seeds, plus something to decorate
  • 1 tsp vanilla extract
  • 100g self-raising flour
  • 100g plain wholemeal flour
  • 1 teaspoon Baking powder
  • 85g powdered sugar
  • 200g pack of full fat soft cheese
  • 4 tbsp lemon curd (optional)


Baking with zucchini
Zucchini can retain quite a bit of water, which can affect the finished consistency of your cake. If your grated zucchini seems watery, place them in a clean cloth and wring out some of the liquid in a bowl. Then add the zucchini to the cake mixture as usual. The timing of making zucchini cakes may depend on the water content of your zucchini. Therefore, if necessary, put the cake in the oven for another 10 minutes. Just test it with a skewer and make sure it comes out clean.

Preparation steps

  1. Preheat the oven to 180°C/160°C fan/gas 4.
  2. Grease 2 x 20 cm sandwich tins and line the bottom with baking paper.

  9. Mix another tablespoon of lemon juice with 25 g of powdered sugar to make a drizzle.
  10. In a separate bowl, mix the remaining powdered sugar, butter, soft cheese, remaining lemon juice and grated lemon peel.

  12. Allow the cakes to cool in the pan for 15 minutes, then transfer to a cooling rack.
  13. Pierce the cakes several times with a cocktail skewer and squeeze the lemon over them.
  14. Allow the cakes to cool completely.

Health Benefits of Frosted Zucchini and Lemon Cake

The Frosted Zucchini Lemon Cake not only satisfies your sweet tooth but also offers several health benefits. From the nutritious zucchini to the zesty lemons, this cake is full of deliciousness that you can enjoy guilt-free.

Nutrient-rich ingredients

This recipe consists of two medium sized zucchini coarsely grated and added to the cake mix. Zucchini is low in calories and rich in essential nutrients. They are an excellent source of fiber, which aids digestion and keeps you feeling full for longer. In addition, zucchini contain high water content, which helps maintain hydration.

An explosion of vitamin C

Lemons are the main ingredient in this cake and provide a tangy and refreshing taste. Lemons are a powerhouse of vitamin C, which acts as an antioxidant and supports a healthy immune system. Vitamin C is also important for collagen formation, promotes healthy skin and prevents oxidative cell damage.

Heart-healthy fats

The recipe includes a 250g pack of unsalted butter, which provides the cake with the necessary fat content. While butter should be consumed in moderation, opting for unsalted butter can be beneficial. It contains heart-healthy fats such as monounsaturated and polyunsaturated fats, which may help lower bad cholesterol and reduce the risk of heart disease.

High-fiber flours

The Frosted Zucchini Lemon Cake contains self-raising flour and plain whole wheat flour. Whole wheat flour retains the bran and germ of the grain, making it higher in fiber compared to refined flour. A diet rich in fiber supports healthy digestion, helps with weight management and reduces the risk of chronic diseases such as diabetes and heart disease.

Lighter frosting option

The frosting for this cake is full-fat soft cheese, which makes for a creamy and delicious topping. If you prefer a lighter alternative, you can skip the frosting or use a low-fat cream cheese as a substitute.

Additional tips

If your grated zucchini seems watery, it’s a good idea to drain some of the liquid so as not to affect the consistency of the cake. For best results, wrap the zucchini in a clean cloth and squeeze out the excess water.

When baking cakes with zucchini, the water content of the zucchini can affect the baking time. If necessary, put the cake back in the oven for another 10 minutes and use a skewer to check whether it is done.

Adding this nutritious and delicious Frosted Zucchini Lemon Cake to your dessert repertoire will allow you to enjoy a guilt-free treat that is both delicious and health-promoting.
