Common Mistakes to Avoid
Making protein cookies can be simple, but there are a few common pitfalls. Avoid these mistakes to ensure your cookies turn out perfectly every time.
- Using regular peanut butter – Many people forget that regular peanut butter can contain added sugars and oils. Use natural peanut butter for the best flavor and health benefits.
- Skipping the egg – While there is an eggless option, skipping it entirely without a substitute can lead to crumbly cookies. If you’re avoiding eggs, replace it with unsweetened applesauce or flaxseed meal.
- Not measuring ingredients accurately – Improper measurements can alter the texture and taste of your cookies. Always use measuring cups and spoons for precision.
- Overbaking the cookies – Leaving them in the oven for too long can make them dry and hard. Keep a close eye on your cookies, especially towards the end of the baking time.
- Ignoring cooling time – Removing cookies from the oven doesn’t mean they’re done! Letting them cool on the baking sheet ensures they firm up properly.
