Can you use baking powder and xanthan gum soda in a cake?

No, you cannot use baking powder and xanthan gum in place of soda in a cake.

Here's why:

- Baking powder contains a leavening agent (baking soda) and an acid (cream of tartar). When these two ingredients are combined with water, they react to produce carbon dioxide gas, which causes baked goods to rise.

- Xanthan gum is a polysaccharide that is commonly used as a thickening agent or stabilizer in food products. It does not have any leavening properties, so it cannot replace baking soda in a cake.

If you use baking powder and xanthan gum in place of soda in a cake, the cake will not rise properly and will have a dense, gummy texture.
