Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

150 g fine polenta (cornmeal)
100 g all-purpose flour
150 g unsalted butter, softened
180 g granulated sugar
3 large eggs, room temperature
Zest of 2 lemons
60 ml fresh lemon juice
2 teaspoons baking powder

Directions

1. Preheat your oven to 170°C (340°F). Grease and line an 8-inch (20 cm) round cake pan with parchment paper.
2. In a large mixing bowl, cream the softened butter and sugar together until light and fluffy. This should take about 3–4 minutes using an electric mixer.
3. Add the eggs one at a time, beating well after each addition to ensure the mixture stays smooth and emulsified.
4. Stir in the lemon zest and lemon juice, mixing until fully incorporated.
5. In a separate bowl, whisk together the fine polenta, all-purpose flour, and baking powder.
6. Gradually fold the dry ingredients into the wet mixture using a spatula. Mix gently just until combined; avoid overmixing to keep the cake tender.
7. Pour the batter into the prepared cake pan and smooth the top evenly.
8. Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.
9. Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slice gently and serve.

Servings and timing

Preparation time: 15 minutes
Baking time: 40–45 minutes
Total time: Approximately 60 minutes

Variations

For a lemon glaze, mix 120 g powdered sugar with 2–3 tablespoons fresh lemon juice and drizzle over the cooled cake.

For a layered version, slice the cake horizontally and spread a thin layer of homemade lemon curd or lightly sweetened whipped cream in the center.

For extra texture, add 30 g of finely ground almonds to the dry ingredients.

For a dairy-free option, substitute the butter with 150 g of a plant-based baking margarine suitable for cakes.

Storage/Reheating

Store the cake in an airtight container at room temperature for up to 3 days. If your kitchen is warm, refrigerate it for up to 5 days and bring it to room temperature before serving for the best texture.

To freeze, wrap the fully cooled cake tightly in plastic wrap and then in foil. Freeze for up to 2 months. Thaw overnight in the refrigerator and allow it to come to room temperature before serving.

If you prefer it slightly warm, heat individual slices in the microwave for 10–15 seconds.

FAQs

Can I use coarse polenta instead of fine polenta?

Fine polenta is recommended for a tender texture. Coarse polenta may result in a gritty cake.

Can I make this cake gluten-free?

Yes, you can replace the all-purpose flour with a gluten-free flour blend designed for baking.

Why did my cake turn out dense?

Overmixing the batter or not creaming the butter and sugar properly can cause a dense texture.

Can I reduce the sugar?

You can reduce the sugar to 150 g, but the cake may be slightly less moist and less sweet.

Can I use bottled lemon juice?

Fresh lemon juice is best for flavor, but bottled juice can be used in the same quantity if necessary.

How do I know when the cake is done?

Insert a toothpick into the center. If it comes out clean or with a few dry crumbs, the cake is ready.

Can I bake this in a loaf pan?

Yes, but the baking time may increase to 50–55 minutes. Check for doneness with a toothpick.

What can I serve with this cake?

It pairs beautifully with whipped cream, fresh berries, or a light dusting of powdered sugar.

Can I make this cake ahead of time?

Yes, this cake actually tastes even better the next day as the flavors develop.

Why did my cake sink in the middle?

Opening the oven door too early or underbaking can cause the center to sink. Ensure the cake is fully baked before removing it.

Italian Lemon Polenta Cake is a timeless dessert that combines rustic charm with bright citrus flavor. Its tender crumb and refreshing lemon notes make it both comforting and elegant. Whether served simply with tea or dressed up for guests, this cake is sure to become a favorite in your kitchen.
