Baking Soda + Cream of Tartar (Best Option)
1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per 1 teaspoon baking powderBaking powder is essentially baking soda combined with an acid and a moisture absorber. Cream of tartar is a dry acid that reacts with baking soda to release carbon dioxide gas, which helps lighten the texture. In energy balls, this reaction is subtle but helps prevent dense or overly compact results.
To ensure success, mix the baking soda and cream of tartar thoroughly with the dry ingredients before combining with wet ingredients. Since energy balls are often no-bake or minimally baked, the reaction mostly occurs during mixing and resting.
Compared to commercial baking powder, this substitute provides a clean rise without off-flavors or added salts, maintaining the intended chewiness and density of energy balls.
