Common Mistakes to Avoid
Baking cookies can be tricky, but avoiding common mistakes can help you achieve the perfect batch of Peanut Butter Oatmeal Chocolate Chip Cookies.
- Boldly measuring ingredients – Accurate measurements are vital in baking. Use a kitchen scale for precision or spoon and level dry ingredients instead of scooping directly from the container.
- Ignoring room temperature butter – Using melted butter can lead to flat cookies. Always ensure your butter is softened to room temperature for the right texture.
- Overmixing the dough – Mixing too much can create tough cookies. Mix just until combined, especially after adding the flour.
- Skipping chilling time – If your dough is too sticky, chilling it for 30 minutes makes it easier to handle and helps cookies maintain their shape during baking.
- Not using parchment paper – Baking without parchment can cause sticking and uneven browning. Always line your cookie sheets for the best results.
