Common Mistakes to Avoid

When making 3 Ingredient Sugar Free Peanut Butter Cookies, it’s easy to overlook some details. Here are common mistakes to avoid:

Skipping the creaming step: Many think they can skip creaming the peanut butter and sugar alternative together. This step is crucial for achieving a light texture. Always cream until fluffy.
Not measuring ingredients properly: Incorrect measurements can lead to dense cookies. Use a dry measuring cup for the peanut butter and ensure you pack the sugar alternative as needed.
Ignoring baking times: Overbaking can lead to dry cookies. Keep an eye on them and check around the 7-minute mark for a golden edge.
Not cooling properly: Transferring cookies immediately from the sheet to a rack can cause breakage. Allow them to cool slightly first, so they set better.
Using the wrong sugar alternative: Not all sugar substitutes behave the same way in baking. Make sure to use one that works well for cookies, like erythritol or stevia blends.
