To make bread using baking powder instead of yeast, you can use a recipe that includes baking powder as a leavening agent. Baking powder helps the bread rise without the need for yeast. Simply mix the baking powder with the dry ingredients, then add the wet ingredients and bake the bread according to the recipe instructions.
Quick bread is a type of bread that is leavened with baking powder or baking soda instead of yeast. It is called "quick" because it does not require the time-consuming process of proofing and rising that yeast bread does. This makes quick breads faster and easier to make.
Yeast dies under the heat of baking, and the gasses it produced expand to make the bread rise further.
Yeast
It's the yeast fermenting and respiring which produces carbon dioxide, causing the bread to rise
The quickest way to make bread without the need for rising time is to make a type of bread called "quick bread." Quick breads use baking powder or baking soda as leavening agents instead of yeast, so they can be baked immediately after mixing the ingredients.
A variety of baking supplies - called "leaveners" - make bread rise. Depending on the kind of bread and the type of recipe, one might use yeast, baking soda, or baking powder.
One of the by products of baking things with yeast is that the yeast, along with making the cake or bread rise, makes alchol . . . just enough to smell good along with the natural baking aromas of the cake or bread.
Baking soda is not normally used to make bread; yeast or a sourdough/poolish are the leaveners. Quick bread (such as Irish soda bread) would generally require 1teaspoon baking soda.
Yeast is a leaven. A chemical reaction between the yeast and water creates tiny gas bubbles, making dough expand.
Yeast is the most popular rising agent for bread. However, on rare occasions, such as in the unavailability of yeast, some persons use baking powder.
A well-made quick bread should be moist and hold together well. Not too dry, and not too moist or heavy.
