- Peanut Butter: Use creamy peanut butter for the best results. Avoid natural peanut butter, it can make the dough too oily or dry. Leftover peanut butter? Use it in a small batch of peanut butter fudge or a small batch of peanut butter bars.
- Sugar: A mix of granulated and brown sugar adds sweetness and depth. Brown sugar brings a hint of molasses. No brown sugar? Try our small batch brown sugar recipe.
- Egg Yolk: Just one yolk is needed. Using the whole egg will affect the texture. Save the egg white for recipes like small batch flourless chocolate cookies or two chocolate cupcakes.
