Easy Classic Olive Oil Cake That Stays Moist for Days

Olive oil cake fixes the problem every baker dreads: dry, crumbly cake by day two. Swap the butter for a good glug of olive oil and each slice stays soft and tender for days, not hours. Better still, this one barely costs a thing.

Flour, sugar, eggs, milk, and a splash of olive oil are pantry staples you probably already own, so you skip the bakery markup completely. Olive oil also trades saturated butter for heart-healthy monounsaturated fats, which makes this a lighter, Mediterranean-style treat with a fresh lemon lift. One bowl, one whisk, and zero fancy equipment.

Why You’ll Love This Recipe

• One bowl, one whisk. No creaming butter, no stand mixer, no mess.
• Stays moist for days. The olive oil keeps every slice soft long after butter cakes go stale.
• Budget pantry staples. Everything here is cheap and probably already in your kitchen.
• Naturally lighter. Good fats instead of butter, plus a bright hit of fresh lemon.

Fabian’s Budget & Health Tip: Skip the pricey “cake flour” and bottled lemon juice. Plain all-purpose flour works perfectly, and one fresh lemon gives you both the zest for the batter and a little juice to brush on top. Buy your olive oil in the larger tin instead of the tiny bottle, and your cost per cake drops fast.

Ingredients (Serve 2)

Baked in a small 6-inch (15 cm) round pan or a mini loaf pan.

• 2/3 cup (85 g) all-purpose flour
• 1/3 cup (80 ml) olive oil
• 1/3 cup (65 g) granulated sugar
• 1 large egg
• 1/4 cup (60 ml) milk
• 1 tsp lemon zest
• 3/4 tsp baking powder
• 1/8 tsp salt

Step-by-Step Instructions

Heat the Oven and Prep the Pan

🔥 Set your oven to 350°F (175°C). Grease your small pan and line the base with a circle of parchment. Letting the oven fully preheat is what gives you that even, domed top.

Whisk the Egg and Sugar

🥚 Crack the egg into a bowl with the sugar. Whisk hard for about two minutes until the mixture turns pale lemon-yellow and thick enough to fall off the whisk in ribbons. This is where the cake gets its light, soft crumb.

Stream in the Oil and Milk

🫒 Pour the olive oil in a slow, steady stream while you keep whisking. Watch the batter turn glossy and silky, almost like a loose custard. Add the milk and lemon zest, and your bowl should suddenly smell bright and citrusy.

Fold in the Dry Ingredients

🥄 Tip in the flour, baking powder, and salt. Switch to a spatula and fold gently, just until the last streaks of flour vanish. Stop the moment it looks smooth. Overmixing here is what turns a tender cake tough.

Bake Until Golden

⏲️ Pour the batter into your pan and smooth the top. Bake for 28 to 32 minutes. You want a deep golden top that springs back when you press it lightly, and a toothpick that slides out clean. By now, your kitchen should smell like warm citrus and toasted olive oil.

Cool Before Slicing

❄️ Rest the cake in its pan for 10 minutes, then turn it out onto a rack. Wait until it is fully cool before slicing, so you get clean, moist pieces instead of a crumbly mess.

Expert Troubleshooting & FAQs

Why did my cake turn out dense or gummy?

Almost always overmixing. Once the flour goes in, fold just until it disappears, and then stop. A heavy hand or extra stirring knocks out the air you whisked into the eggs, and that air is what keeps the crumb light.

Can I actually taste the olive oil?

A little, and in the best way. It reads as fruity and savory in the background, not greasy. If you want a softer flavor, reach for a mild or “light” olive oil. For a bolder, more Mediterranean note, use a fruity extra-virgin.

How do I store it so it stays moist for days?

Wrap the cooled cake tightly or pop it in an airtight container and keep it at room temperature for 3 to 4 days. The olive oil does the heavy lifting here and keeps every slice soft well past when a butter cake would dry out.
