About 1.5 teaspoons. If the recipe calls for self raising flour and you don't have any then add 1.5 teaspoons of baking powder and 0.5 teaspoons of salt.
The amount of baking powder required depends entirely on what you intend to bake. Different types of cookies, muffins and other baked goods require different proportions of baking powder to flour.
Cake flour is much finer. Sometimes it is combined with baking powder, so you have to check the box on the brand you buy because you won't need to add the baking powder in the recipe if the brand contains it. Cake flour gives a much lighter texture. If you need to substitute all purpose flour for cake flour, then use 1 cup minus 2 Tbsp. of all purpose flour for every cup of cake flour called for in the recipe.
Probably not. Baking mix has other ingredients such as baking soda/powder and dried milk or eggs. What type of baking mix is it and what are you making? If you're just battering something it will be fine, but if you're baking something, not so much.
Yes. But add twice as much. When you use self-raising flour, add 1 tspoon of baking powder, to lighten the cake. So just add about 1 tbspoon if using plain flour.
You can but you need to add baking powder and salt to it.
What do you think?
You replace a cake mix by making the cake from scratch. Any cake recipe from a cook book or found online will tell you how much flour, sugar, baking powder or baking soda, salt and other ingredients to use.
around 3 teaspoons, but this will vary according to the recipe.
the purpose of baking powder in a cake is to make it rise and not make it flat and if you put too much of baking powder your cake might burst in the oven/microwave what ever you use
Generally you use 1 to 2 teaspoons of baking powder to each cup of flour.
I don't know how much volume 4 oz. will be, but most recipes use the ratio of 1 teaspoon of baking powder to 1 cup of flour. Weigh the flour, measure it and find the amount of baking powder that way.
