Bolo de Agua — Portuguese Water Cake — is one of those recipes that proves you don’t need much to create something truly special. My mom would bake this on weekends, always ready for company that might drop by, and the smell of it coming out of the oven is something I’ll never forget. Simple ingredients, no frosting, no fuss — just a light, lemon-scented cake that tastes exactly like home.
What is Bolo de Agua?
Bolo de Agua, which translates literally to “water cake,” is a traditional Portuguese sponge cake made with flour, eggs, sugar, water, and lemon zest — nothing more. The name comes from the use of water rather than butter or oil, which gives the cake its characteristically light, airy texture. It’s baked in a tube pan, similar to an angel food cake, and it’s a staple of Portuguese home baking. You’ll find versions of this cake at festas, family gatherings, and Sunday tables all across Portugal and the Azores.
How to Make This Bolo de Agua Recipe
The key to this cake is in how you handle the eggs. The whites and yolks are separated — the whites beaten to stiff peaks and folded in at the end, which is what gives Bolo de Agua its lift. Beat the yolks with the sugar and warm water first, then gradually incorporate the flour mixture. Fold in the lemon zest with a wooden spoon, then gently fold in the egg whites — don’t overmix or you’ll lose the airiness. Pour into a well-greased and floured tube pan and bake at 350°F for 60 minutes.
Tips for the Best Bolo de Agua
- Use room temperature eggs. Cold eggs don’t whip as well — take them out of the refrigerator at least 30 minutes before you start.
- Beat the egg whites to stiff peaks. They should hold their shape when you lift the beater. Under-whipped whites will give you a dense cake.
- Fold, don’t stir. When incorporating the egg whites, use a gentle folding motion to keep as much air in the batter as possible.
- Grease and flour the pan thoroughly. This cake has no butter in it, which means it will stick if the pan isn’t properly prepared. Don’t skip this step.
- Don’t open the oven door early. This is a delicate sponge — opening the oven before 50 minutes can cause it to collapse in the center.
- Use fresh lemon zest. It makes a real difference — bottled lemon extract is not the same.
- Test with a toothpick at 60 minutes. Ovens vary — if it comes out clean, you’re done. If not, give it another 5 minutes.
I use a 10″ Angel Food Cake pan from Nordic. It’s heavy weight, so it will last you, and it has a non-stick finish.

Serving and Storing
Bolo de Agua is best served at room temperature, sliced thin. It needs nothing — no glaze, no cream, no topping — though a light dusting of powdered sugar is a nice touch for company. Store covered at room temperature for up to 3 days, or wrap tightly and freeze for up to 2 months.
