Pro Tips from My Kitchen
✓ Use Room Temperature Ingredients – Cold ingredients can affect the texture of your cookies. Make sure your egg and peanut butter are at room temperature for the best results.
✓ Don’t Overbake – Keep an eye on your cookies as they bake. They continue to firm up after being removed from the oven, so taking them out just before they look done will yield a softer cookie.
✓ Experiment with Mix-ins – If you want to add a personal twist, try incorporating chocolate chips or crushed nuts for added texture and flavor.
✓ Store Properly – To keep your cookies fresh longer, store them in an airtight container at room temperature. They also freeze well!
✓ Double the Recipe – If you’re baking for a crowd or want extra for later, simply double the ingredients. They’re so quick to whip up, it won't feel like a chore!
