FAQs
Can I use whole eggs instead of just the yolk?
Yes, you can use a whole egg, but the texture might be slightly different and less rich. Using only the yolk keeps the cookie fudgier.
What does heat-treated flour mean and why is it important?
Heat-treating flour means lightly cooking it in the microwave or oven to kill any harmful bacteria. Since this recipe uses raw flour, heat treatment ensures it’s safe to eat without fully baking.
