Old-Fashioned Chocolate Cake
This is the birthday cake, the "someone's coming over" cake, the cake grandma could make with her eyes closed and a wooden spoon. Deep, dark and properly moist, with a glossy fudge frosting that sets soft — not the fussy kind you need a piping bag for, just the kind you swoop on with a knife and can't stop picking at from the bowl.
The trick that surprises people: hot coffee in the batter. It doesn't make the cake taste of coffee — it blooms the cocoa and deepens the chocolate into something rich and grown-up, while keeping the crumb wonderfully moist. (Hot water works too, if you'd rather.) The batter comes out alarmingly thin, and that's exactly right; thin batter bakes into a tender, damp crumb.
The other rule is the same one grandma repeated for every cake: don't overbake it. Pull it when a skewer shows a few moist crumbs. A dry chocolate cake is a genuine tragedy, and an entirely avoidable one.

Ingredients
For the cake
- 200 g plain flour
- 75 g cocoa powder
- 1½ tsp baking powder & 1½ tsp bicarb
- ½ tsp salt
- 350 g caster sugar
- 2 eggs
- 240 ml buttermilk & 120 ml oil
- 2 tsp vanilla
- 240 ml hot strong coffee (or hot water)
For the fudge frosting
- 120 g butter & 60 g cocoa
- 300 g icing sugar, 90 ml milk, 1 tsp vanilla
Method
- Batter. Oven to 175°C (fan 155°C / gas 4); grease and line two 20 cm tins. Whisk the dry ingredients, then whisk in the eggs, buttermilk, oil and vanilla until smooth.
- Hot coffee last. Stir in the hot coffee — the batter goes very thin, which is exactly right. It blooms the cocoa for deep flavour and a moist crumb.
- Bake. Divide between tins; 30–34 minutes, until a skewer shows a few moist crumbs. Don't overbake. Cool 10 minutes in the tins, then fully on a rack.
- Frosting. Melt the butter, stir in the cocoa, then beat in the icing sugar and milk alternately to a glossy, spreadable fudge. Beat in the vanilla.
- Frost. Sandwich, then cover top and sides. Set 20 minutes before slicing — if you can.
Line the tin bases with a disc of baking paper — a chocolate cake stuck to the tin is heartbreak you can avoid in ten seconds.
Tips for a moist chocolate cake
Hot coffee blooms cocoa
It deepens the chocolate, not adds coffee flavour. Hot water works if you'd rather.
Thin batter is right
Don't be alarmed — a thin batter bakes into the tender, damp crumb you want.
Pull it early
A few moist crumbs on the skewer means done. Bone-dry means you've gone too far.
Questions, answered
Does it taste of coffee?
No — the coffee deepens the chocolate rather than adding its own flavour. Prefer to skip it? Use the same amount of hot water; still lovely, just a touch less deep.
Why is my chocolate cake dry?
Overbaking or too much flour. Weigh the flour, and pull the cakes when a skewer shows a few moist crumbs — the oil and buttermilk keep it moist, but a few extra minutes undoes them.
Sheet cake or cupcakes?
Yes to both — a 23×33 cm sheet (~35 minutes) or about 24 cupcakes (18–20 minutes). The frosting covers any of them generously.
What's old-fashioned fudge frosting?
A beaten cocoa-butter-and-sugar frosting that sets to a soft fudge rather than a fluffy buttercream — glossy, deeply chocolatey, and the traditional finish. This one's beaten, so no thermometer needed.
