Jamie Oliver’s Polenta Lemon Cake is a lemon-flavored cake made with ground almonds and polenta, rather than traditional flour. Polenta adds a slight crunch and unique texture, while ground almonds keep the cake moist and rich. Lemon zest and juice bring a burst of fresh citrus flavor, making this cake ideal for anyone who loves lemon desserts.
Preheat your oven to 180°C (350°F). Grease a 20cm round cake tin and line it with parchment paper for easy removal.
In a mixing bowl, combine the ground almonds, polenta, and baking powder. Stir to combine and set aside.
In a separate bowl, whisk together the caster sugar, eggs, and olive oil (or vegetable oil) until well combined. Add the lemon zest and juice, and whisk until smooth.
Gently fold the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix to keep the cake tender.
Pour the batter into the prepared cake tin and smooth the top with a spatula.
Bake in the preheated oven for 35-40 minutes, or until a skewer inserted into the center comes out clean. The top should be golden, and the cake should feel springy to the touch.
While the cake is baking, you can prepare the lemon syrup. In a small saucepan, combine the caster sugar and lemon juice. Heat gently, stirring, until the sugar has dissolved and the mixture forms a syrup. Set aside.
Allow the cake to cool in the tin for 10 minutes, then transfer it to a wire rack. While the cake is still warm, brush the lemon syrup over the top for extra lemon flavor and moisture.
Slice and serve the cake as is, or garnish with a dusting of powdered sugar, fresh berries, or a dollop of whipped cream.
