Chelsea Clinton's take on National Pancake Day puzzled many on social media. 

The former First Daughter tweeted a picture of some very green spinach pancakes. 

"Spinach pancakes for #NationalPancakeDay (we won't eat them all tonight although Charlotte would if we let her)!" Clinton wrote. 

The pic prompted a lot of funny responses on Twitter... 


Clinton later explained that the idea is a good way to get more iron in her two-year-old daughter Charlotte's diet. 

The 37-year-old Clinton has two children with her husband, hedge fund investor Marc Mezvinsky. The couple, married in 2010, also has a baby son, Aidan, who was born last June.
