Common Mistakes to Avoid

Using runny peanut butter—it makes the cookies spread too much.
Overbaking—keto cookies firm up as they cool, so remove them early.
Skipping the fork crisscross pattern—the dough needs flattening to bake evenly.
Using granulated sweetener only—may cause graininess; powdered sweetener is smoother.
