Baking Powder (Best Option)
3/4 teaspoon per 1/2 teaspoon baking sodaBaking powder contains both an acid and a base, allowing it to release carbon dioxide when moistened and heated, which helps with leavening in energy balls. Since energy balls are often no-bake or minimally heated, the leavening effect is subtle but still beneficial for texture.
To ensure proper activation, mix baking powder thoroughly with dry ingredients. Avoid adding extra acidic components as baking powder already contains acid.
Compared to baking soda, baking powder produces a milder rise and can slightly soften the texture, but it maintains the chewiness and density typical of energy balls.
