It's peanut butter jelly time! Today is the day to celebrate your favorite childhood lunchbox staple, the peanut butter and jelly sandwich. In the United States, April 2 is National Peanut Butter and Jelly Day.

It is believed that American soldiers created the peanut butter and jelly sandwich during World War II. During this time, both peanut butter and jelly were on the rations menu for the United States military. To make peanut butter sandwiches more palatable, soldiers added jelly. The rest is history. 

National Peanut Butter and Jelly Day originally celebrated the peanut butter and jelly sandwich, but nowadays, peanut butter and jelly can be found in a variety of recipes. 

Here are five peanut butter and jelly recipes that will make you thank the veteran geniuses of World War II:
