Out of baking powder

Lift, on a clock. It starts working the moment it is wet and again in the oven, so a batter that sits on the counter has already spent half of it.

Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.

What to reach for

Instead · 1

baking soda plus an acid

a quarter teaspoon of soda and half a teaspoon of cream of tartar per teaspoon of powder

What it gets you
Baking powder, made, because that is what baking powder is.
What it costs you
The second rise. Commercial powder is double-acting and this is not, so the batter goes in the oven immediately.

Instead · 2

baking soda plus buttermilk or yogurt in the batter

a quarter teaspoon of soda per teaspoon of powder, and swap some liquid for buttermilk

What it gets you
Lift, and a more tender crumb, which is why old recipes work this way.
What it costs you
The recipe's liquid balance, which has to move to accommodate it.

Instead · 3

self-rising flour, if you also have that

swap the flour entirely and drop the powder and the salt

What it gets you
The right amount of leavening already blended in.
What it costs you
Control over the ratio, which matters in a delicate cake.

What none of them do

There is no swap that gets you lift without a chemical reaction. If there is no soda and no powder in the house, the honest move is to make something that does not rise.

Where the swap will be tasted · 3

These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes baking powder a quarter of what is in the pan. Make the swap a decision rather than a repair.

Check what else is in the pan

The company baking powder keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
