What You’ll Need

For the Cake:

• Plain flour – 10 oz (280g)
• Caster sugar – 8 oz (225g) (superfine sugar)
• Vegetable oil – 1/2 cup (120ml) (or sunflower oil)
• Large eggs – 3, at room temperature
• Milk – 1 cup (240ml) (any type)
• Baking powder – 2 teaspoons
• Vanilla extract – 2 teaspoons
• Salt – 1/2 teaspoon
• Hot water – 1/2 cup (120ml)

For Simple Frosting (Optional):

• Icing sugar – 12 oz (350g), sifted
• Cream cheese – 4 oz (115g), softened (or more oil for vegan)
• Vanilla extract – 1 teaspoon
• Milk – 2-3 tablespoons

Equipment:

• 9-inch round cake tin or 8×8-inch square tin
• Large mixing bowl
• Whisk or electric mixer
• Measuring cups and spoons

Oil Options & Substitutions:

• Best oils: Vegetable, sunflower, or light olive oil
• Coconut oil: Use melted (not solid) for tropical flavor
• Applesauce: Replace half the oil for lower fat version
• Greek yogurt: Can replace up to 1/4 of the oil
• Dairy-free: Use plant milk and skip cream cheese frosting

Step-by-Step Directions

Getting Ready:

1. Preheat your oven to 350°F (180°C). Grease your cake tin thoroughly with oil or cooking spray, then line the bottom with parchment paper. Oil-based cakes can be slightly stickier, so don’t skip the greasing!
2. Gather your ingredients. Unlike butter cakes, you don’t need to worry about temperature—this recipe is very forgiving. Just make sure your eggs aren’t straight from the fridge.

Making the Batter:

3. Mix dry ingredients. In a large bowl, whisk together flour, sugar, baking powder, and salt. Make sure there are no lumps—sifting isn’t essential, but a good whisk does the job.
4. Combine wet ingredients. In a separate bowl or large measuring cup, whisk together oil, eggs, milk, and vanilla until well combined. The mixture should look smooth and slightly thick.

Oil Tip: Room temperature ingredients mix better, but this recipe is forgiving if you forget to take things out early.

5. Bring it all together. Pour the wet ingredients into the dry ingredients and stir with a wooden spoon or whisk until just combined. Don’t worry about a few small lumps—overmixing is your enemy here.
6. Add the magic ingredient. Gradually stir in the hot water. This might seem odd, but it creates steam during baking, resulting in an incredibly light and moist cake. The batter will be quite thin—this is normal!

Hot Water Secret: This technique is borrowed from professional bakeries and makes all the difference in texture.

Baking:

7. Pour into prepared tin. Transfer the batter to your prepared cake tin. Give the tin a gentle tap on the counter to release any air bubbles.
8. Bake until perfect. Bake for 28-32 minutes until the top springs back when lightly touched and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
9. Cool completely. Let the cake cool in the tin for 10 minutes, then turn out onto a wire rack. This cake is delicate when warm, so patience pays off here.

Optional Frosting:

10. Make simple frosting. Beat cream cheese until smooth, then gradually add sifted icing sugar, vanilla, and enough milk to reach spreading consistency. For a vegan version, use additional oil and a splash of lemon juice.
11. Decorate as desired. Once the cake is completely cool, spread frosting evenly over the top, or simply dust with icing sugar for a classic finish.

Expert Tips for Success

Moisture Secrets:

• Don’t overbake—oil cakes can go from perfect to dry quickly
• Store covered—this cake actually gets more moist over 24 hours
• Hot water technique creates steam for extra tenderness

Oil Selection:

• Neutral oils (vegetable, sunflower) let other flavors shine

• Avoid strong oils like coconut unless you want that flavor

Storage Wisdom:

• Keeps fresh for 4-5 days at room temperature (covered)

Troubleshooting:

• Dense cake: Usually from overmixing—stir just until combined

• Sunken middle: Oven too hot or door opened too early

Professional Secret: Many bakeries prefer oil cakes because they stay moist longer and have more consistent results than butter cakes.

Common Questions

Why use oil instead of butter in cakes?

Oil creates a more tender, moist texture that lasts longer than butter cakes. Oil is 100% fat (butter is only about 80% fat), so it coats flour proteins more effectively, preventing tough, chewy textures. Plus, oil cakes don’t get hard when chilled like butter cakes do.

What’s the best oil to use for baking?

Vegetable oil or sunflower oil are ideal because they have neutral flavors and high smoke points. Light olive oil works well too. Avoid coconut oil unless you want coconut flavor, and never use strong oils like sesame or walnut as they’ll overpower the cake.

Can I substitute the oil with something healthier?

Yes! You can replace up to half the oil with unsweetened applesauce or Greek yogurt for a lighter version. The cake will be slightly less rich but still deliciously moist. For fully oil-free, try mashed banana, but expect a denser texture and banana flavor.

Why does the recipe call for hot water?

The hot water creates steam during baking, which helps develop a tender, fluffy crumb. It also helps dissolve the sugar more completely and creates a smoother batter. This technique is commonly used in professional bakeries for consistently moist cakes.

How do I know when an oil cake is done?

Oil cakes can look underdone when they’re actually perfect. Look for a cake that springs back when lightly touched in the center and has started to pull slightly from the sides. A toothpick should come out clean or with just a few moist crumbs—completely clean might mean it’s overbaked.

Can I make this cake vegan?

Absolutely! Replace the eggs with flax eggs (3 tablespoons ground flaxseed mixed with 9 tablespoons water, left to thicken), use plant milk, and skip the cream cheese frosting or make it with vegan cream cheese. The cake will be just as delicious!
