How to Say "baking powder" in Spanish
The Spanish word for “baking powder” is “royal” — B1 level.

Examples
Necesito un sobre de royal para que el bizcocho suba.
I need a packet of baking powder so the sponge cake rises.
Mezcla la harina con una cucharadita de royal antes de añadir los huevos.
Mix the flour with a teaspoon of baking powder before adding the eggs.
Si no le pones royal, la masa se quedará muy plana.
If you don't add baking powder, the dough will stay very flat.
A Brand as a Word
'Royal' is actually a brand name, but in many Spanish-speaking homes, it is the only word people use for baking powder, much like 'Kleenex' is used for tissues.
Choosing the Gender
It is usually masculine ('el royal') because it refers to 'el polvo' (the powder), but you might occasionally hear 'la royal' if someone is thinking of 'la levadura' (the yeast).
The 'Royal' vs. 'Real' Trap
Mistake: “Using 'royal' to describe a king or queen.”
Correction: Use 'real' for anything related to royalty (e.g., 'el palacio real'). 'Royal' in Spanish is almost exclusively for the kitchen!
