There is no greater sense of anticipate than realizing that a recipe calls for baking soda but you only have baking powder. I’ve been there. Baking soda and baking powder act in distinct ways, despite their similarities. Swapping one teaspoon baking powder for baking soda will not work as well and may ruin your muffins. You may use around three times the amount of baking powder to replace baking soda, and it works well in my experience! Just keep in mind that it may have a little effect on the taste and texture. However, for the greatest results, look for a recipe that just calls for baking powder or baking soda
If you have baking soda but not baking powder, you can create a substitute by combining 1/4 teaspoon of baking soda with 1/2 teaspoon of cream of tartar for every teaspoon of baking powder required in your recipe. This mixture provides the necessary leavening effect when baking.
