Nigella’s Gluten-Free Lemon Polenta Cake: A Sunshine-Filled Delight
My earliest memory of this cake is a summery afternoon in my grandmother’s garden. Bees buzzed lazily around lavender bushes, and the air was thick with the scent of lemons and warm butter. She pulled a slightly golden, glistening cake from a tin and offered me a slice. The bright, tangy flavor against the tender crumb was pure sunshine on a plate, and it’s a memory I’ve tried to recapture ever since. This Gluten-Free Lemon Polenta Cake, adapted from Nigella Lawson’s original, comes closest to that perfect afternoon.
Recipe Overview
- Prep Time: 20 minutes
- Cook Time: 40 minutes
- Total Time: 1 hour
- Servings: 12-16
- Yields: 1 cake
- Dietary Type: Gluten-Free
Ingredients
- 3/4 cup + 2 tablespoons (190g) unsalted butter, softened
- 1 cup (200g) caster sugar (also known as superfine sugar)
- 2 1/4 cups (225g) ground almonds
- 9 tablespoons (55g) cornmeal (also known as polenta)
- 1 1/2 teaspoons gluten-free baking powder
- 3 large eggs
- Zest of 2 lemons (reserve the juice for the syrup)
For the Syrup:
- Juice of 2 lemons
- 1 cup (120g) powdered sugar (also known as icing sugar)
Equipment Needed
- 23cm (9 inch) springform round cake pan
- Parchment paper
- Electric mixer (stand or hand-held)
- Medium saucepan
- Cake tester or toothpick
Instructions
- Preheat your oven to 350°F (175°C). Line the base of a 23cm springform round cake pan with parchment paper. This will prevent the cake from sticking and make it easier to remove. Butter the sides of the tin generously. This helps the cake to rise evenly and prevents sticking.
- In a large bowl, beat the softened butter and caster sugar together using an electric mixer until the mixture is pale and whipped. This usually takes about 3-5 minutes. Properly creaming the butter and sugar is essential for a light and airy cake.
- In a separate bowl, mix together the ground almonds, cornmeal, and gluten-free baking powder.
- Gradually add the dry ingredients to the butter and sugar mixture in stages, alternating with the eggs. Beat well after each addition until all ingredients are thoroughly combined. Be careful not to overmix, as this can result in a tough cake.
- Beat in the zest of 2 lemons. Ensure that you only zest the yellow part of the lemon, avoiding the bitter white pith.
- Scrape the cake batter into the prepared cake tin, spreading it evenly.
- Bake for approximately 40 minutes, or until a cake tester (or toothpick) inserted into the center of the cake comes out clean. If the top of the cake starts to brown too quickly, you can loosely cover it with foil for the last 10-15 minutes of baking.
- While the cake is baking, make the syrup. In a medium saucepan, combine the juice of the 2 lemons and the powdered sugar.
- Heat the mixture over medium heat, stirring constantly, until the powdered sugar is completely dissolved. Once the icing sugar is dissolved the syrup is done. Do not boil the syrup for too long, as it will thicken too much.
- Once the cake is out of the oven, prick the top of the cake all over with the cake tester (or toothpick). This will allow the syrup to penetrate the cake evenly.
- Pour the warm syrup evenly over the top of the cake. The cake should be slightly warm when you pour the syrup over it.
- Leave the cake to cool completely in the pan before removing it. Cooling the cake in the pan helps it to retain its moisture.
Expert Tips & Tricks
- Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for optimal mixing and a smooth batter.
- Don’t Overbake: Overbaking will result in a dry cake. Check for doneness with a cake tester – it should come out clean or with a few moist crumbs attached.
- Lemon Zest is Key: Use a microplane grater for the lemon zest to get the finest zest possible, maximizing the lemon flavor.
- Syrup Timing: Make sure the syrup is warm when you pour it over the warm cake. This helps the syrup absorb into the cake properly. If the syrup cools too much, gently reheat it.
- Pan Preparation: Lining the bottom of the pan with parchment paper is crucial for easy removal. Buttering the sides is also important to ensure the cake doesn’t stick.
Serving & Storage Suggestions
This Gluten-Free Lemon Polenta Cake is delicious served at room temperature. It’s wonderful on its own, or with a dollop of Greek yogurt, a scoop of vanilla ice cream, or a scattering of fresh berries. Store any leftover cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. To freeze, wrap the cooled cake tightly in plastic wrap and then foil; it can be frozen for up to 2 months. Thaw it overnight in the refrigerator before serving.

FAQs (Frequently Asked Questions)
Q: Can I use regular baking powder instead of gluten-free baking powder?
A: While you can, it’s best to use gluten-free baking powder to ensure the cake remains completely gluten-free and has the correct rise and texture.
Q: What if I don’t have caster sugar?
A: Caster sugar is finer than granulated sugar, which helps it dissolve more easily. If you don’t have it, you can pulse granulated sugar in a food processor until it’s finer.
Q: Can I make this cake ahead of time?
A: Absolutely! This cake actually tastes better the day after it’s made, as the syrup has more time to soak in.
Q: The top of my cake is browning too quickly. What should I do?
A: If the top of the cake is browning too quickly, loosely cover it with foil for the last 10-15 minutes of baking.
Q: What if I don’t have a springform pan?
A: While a springform pan is ideal for easy removal, you can use a regular cake pan. Just make sure to line the bottom with parchment paper and grease the sides thoroughly. You may need to invert the cake to remove it carefully.
