Plain and simple Lemon Polenta Cake, a rustic Italian-style cake made with whole grain cornmeal and lots of fresh lemon.
This lemon polenta cake is a family-favorite dessert from my file, a definite keeper recipe.
It’s easy to make, and bakes up into rustic, Italian-inspired cake infused with lemon zest and juice.
The cake has a tender texture and the lovely crunch of coarse cornmeal — a/k/a polenta!
It’s just the sort of homey, plain and simple cake I love.
How to serve lemon polenta cake
This cake is fantastic as a plain tea cake or snack.
Cut it into slices and just eat it with your hands.
Or, sprinkle the top with powdered sugar and serve alongside generous helpings of whatever seasonal fruit is at its sweetest at the moment.
Try lightly sweetened berries, plums or peaches in the summer, or prosecco-poached pears or roasted apples in the fall and winter months.
What is polenta cornmeal?
The difference between baking with very fine cornmeal (cornflour) and coarse cornmeal comes down to texture.
Cornmeal is ground from dried corn, and varies in grind from fine to coarse.
Fine cornmeal is processed to remove gritty texture, and often most of the healthy parts go with it.
I love baking with coarse cornmeal, which is ground from the entire kernel, and it retains the grain’s natural germ and bran.
I even bake rosemary and lemon polenta cookies using this type of coarse cornmeal because I enjoy it so much.
You can find this type of cornmeal in your regular grocery store.
I often buy Bob’s Red Mill Polenta Corn Grits and sometimes splurge on the special cornmeal and corn grits from Anson Mills.
How to Make Lemon polenta cake:
Bring ingredients to room temperature, including the eggs.
Lightly oil your cake pan and parchment paper to easily release the cake from the pan.
Shortcut to room temperature eggs: Crack the whole eggs and whites into a small dish while getting your cake pan and the rest of the ingredients ready.
You can also place the whole uncracked eggs in a bowl of very warm water for 15 minutes.
Whisk dry ingredients, including flour, coarse cornmeal, baking powder and salt in a medium mixing bowl.
Beat eggs, egg whites and sugar in an electric mixer until creamy and light, then fold in the dry ingredients and lemon zest.
Transfer to a lined and oiled 8″ cake pan and bake about 35 minutes at 350 degrees.
Like many cakes, the texture and flavor will actually improve the day after baking – but honestly, in our house it rarely lasts that long!
Keep the wrapped cake at room temperature for several days.
Can you freeze polenta cake?
Lemon polenta cake can be frozen:
Cool completely, then wrap in several layers of plastic wrap and freeze up to 1 month Defrost at room temperature
Easy Lemon Polenta Cake
Ingredients
- 1 cup (165 g) polenta, or stone-ground cornmeal
- 3/4 cup (100 g) all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon fine sea salt
- 2 large eggs
- 2 (60 ml) egg whites (1/4 cup)
- 1 cup (220 g) sugar
- 1/4 cup (60 ml) olive oil or neutral oil such as canola or avocado
- 2 tablespoons (30 g) unsalted butter, softened
- 1/2 cup (125 ml) whole milk plain yogurt or sour cream
- 2 tablespoons grated fresh lemon zest
- 2 tablespoons fresh lemon juice
- Powdered sugar
Instructions
- Preheat oven to 350 degrees (175 C) and place an oven rack in the center of the oven.
- Line the bottom of an 8-inch cake pan with parchment paper to fit (see how-to video above) and lightly brush the bottom and sides of the pan with oil or cooking spray.
- Whisk the cornmeal, flour, baking powder and salt in a bowl and set aside.
- Beat the eggs, egg whites and sugar in a heavy-duty stand mixer on medium-high speed 4-5 minutes, until pale and creamy. On low speed, mix in the oil. butter, yogurt, lemon zest and juice.
- Stir in the dry ingredients until just blended. Pour the batter into the pan and bake 35 – 40 minutes, or until the top feels firm (not hard) and a toothpick inserted in the center of cake comes out clean. Cool in the pan 10 minutes before inverting onto a rack to cool – run a dull knife around the edge of the pan to loosen.
- Sift powdered sugar over the cake and serve.
Notes
- Serve the cake plain or with lightly sweetened fresh fruit.
- The cake keeps well for several days at room temperature.
- I sometimes substitute an Italian lemon olive oil when I feel like splurging – it tastes amazing!
Alice Kemp says
The cake flavor was delicious, but the polenta was so gritty we felt we were eating sand. In future, I will either use cornmeal or soak the polenta in boiling water before use.
Jon says
Excellent polenta cake. Next time I make it, I will likely cut in half and add a layer of something, maybe fresh strawberry jam. It is excellent with fresh fruit as well.
Ann says
Modified the recipe to use Almond flour. Also reduce sugar to 3/4 cup. It was perfect to satisfy my sweet tooth! Love love the texture and the lemon taste!
Maria del FAbro says
This cake is super! Watch out you will want more than one piece. I used almond flour, reduced sugar to 3/4 cup and added 1.5 t vanilla. It has a lovely texture and the taste is rich.
Ingrid says
Hey! Can I sub for GF flour? Thanks!
Familystyle Food says
I’ve had people say they’ve substituted with gluten-free flour and it works great. Let me know if you try it!
Ingrid says
Thanks. Will do! Looking forward x
Suzanne says
Hello,
It seems that your weight conversion for the sugar is incorrect. It says 22g, but 1 cup of sugar is closer to 200g. Can you update?
Thank you!
Familystyle Food says
Hi Suzanne! Thanks so much for pointing out that typo – it’s been changed to 220g, which is from my digital scale.
Tarsha says
My husband is not a huge dessert fan so I made this thinking that it would be less sweet than many desserts. This turned out to be the case. A friend made a lemon custard to go with it and wow! Nobody could keep their hands off it! My stepmother, who is a tiny little thing who lives on salads year round, actually had not one but two large servings! This is a recipe that is going into the family cookbook for often used recipes. Thank you!
Karen says
Thanks so much for letting my know, Tarsha. I love the image of your stepmother digging in to the cake! Glad you all enjoyed.
Tiffany says
I’ve just tried it with some figs on the top : gorgeous ! Thank you so much for this recipe !
Karen says
So happy to hear that Tiffany!
Laura says
Polenta is not cornmeal, in Italian cornmeal is ‘farina di mais’.
Polenta is a kind of mush: You pour cornmeal in hot salted water, and cook it for about one hour; this is polenta.
Amy says
I’ve just made this for my husband but replaced the all purpose flour with gluten free flour and it has worked perfectly! I can’t wait to dive in! Oops sorry, I mean for him to try it 😉
Adri says
My husband is wild for polenta cake. I’ll have to give this a go!
Lisa says
I must try this! Looks delicious!

I’m a bit back logged on my reader – but none-the-less, this cake looks absolutely divine! Given my slight obsession lemon desserts and most recently polenta-anything — this is just begging to be made!
Claire @ Claire K Creations says
I made a similar version of this from Nigella the other day and it was delicious. So dense and full of zing from the lemons. I like the crunch the polenta gives each slice. I hate to admit it but it didn’t last long!
Karen says
Yes, that lemony crunch is slightly habit-forming…I know exactly what you mean, Claire.
