Common Mistakes and How to Avoid Them
Even with just three ingredients, things can go wrong. Here’s how to ensure your cookies turn out perfect:
| Mistake | Why It Happens | How to Fix It |
|---|---|---|
| Cookies too dry | Too much sugar or overbaking | Reduce sugar slightly and bake for a shorter time |
| Cookies falling apart | Not enough binding | Ensure egg is well-mixed and do not overbake |
| Dough too sticky | Natural peanut butter is too oily | Chill the dough for 10 minutes before baking |
| Cookies too hard | Overmixing the dough | Stir just until combined to keep cookies soft |
| Burnt bottoms | Oven temperature too high | Use an oven thermometer to ensure accuracy |
Tips for Nutritious Cookies
- Use natural peanut butter without added sugars or oils.
- Reduce sugar slightly if you prefer a less sweet cookie.
- Pair with a protein source like Greek yogurt for a balanced snack.

- Add fiber by mixing in some ground flaxseeds or chia seeds.
Tips for Success
