Dr. Oetker Backin (baking powder) 80g (5x16g) Baking powder is an agent added to dough to make it rise better. Baking powder is often used as a substitute for yeast, whereas yeast forms other aromas and flavours, baking powder does not. The flavour of the baked product will not change as a result. Baking powder mixed with flour forms a homemade self-rising flour.
