Can you combine baking soda and powder to cup cake what is amount of two?

You generally don't combine baking soda and baking powder in a cupcake recipe. They serve different purposes and using both together can lead to an unpleasant taste or a cake that rises too quickly and then collapses.

Here's a breakdown:

* Baking soda needs an acidic ingredient (like buttermilk, lemon juice, or brown sugar) to activate and create bubbles that make the cake rise.

* Baking powder already contains an acid and reacts with moisture to produce those bubbles.

Here's how to use them correctly:

* If your recipe calls for baking soda, ensure you have an acidic ingredient present.

* If your recipe calls for baking powder, don't add baking soda.

If your recipe doesn't specify either, use baking powder. It's generally more forgiving and will work in most situations.

In a standard cupcake recipe, you'd typically use:

* 1-1.5 teaspoons of baking powder

* 1/2 - 3/4 teaspoon of baking soda (if the recipe requires it and includes an acidic ingredient)

Important Note: Always follow the specific recipe instructions for the best results.
