We seem to celebrate a lot of silly national food holidays, whether for the day or the entire month, but National Ice Cream Month isn't one you should push to the side. Cool yourself down with a bowl of your favorite ice cream, or head on over to Smashburger for the Peanut Butter & Jelly Shake.

Smashburger hand-spins Häagen-Dazs vanilla ice cream with Nutter Butter cookies and strawberry jelly to create its PB&J shake. What was once a secret menu item has now been placed on the regular menu as the featured shake at Smashburger during National Ice Cream Month.

I am a huge fan of peanut butter and jelly sandwiches. In fact, I ate one for lunch every single day during grade school, middle school and high school (for the most part); I even default to this classic sandwich today when I can't decide what to eat for lunch. So when I saw that Smashburger was offering the sandwich in milkshake form, I had to check it out.

After being blended with strawberry jelly, the once-white vanilla ice cream turns a pale shade of pink, making you think you're about to taste a plain strawberry milkshake, but you're in for a surprise. As you sip the shake through the straw you are hit with little chunks of crushed Nutter Butter cookies leaving you with the sweetest combination of peanut butter and jelly you have ever had.

The shake is like having a peanut butter sandwich with überly sweet strawberry jelly and a glass of creamy whole milk, except everything is blended together -- well, minus the bread.

I have to admit I was a little skeptical after the first sip, but once I tasted the sweet Nutter Butter cookie chunks, I couldn't resist taking a few more sips. The only thing that stopped me from consuming the entire shake was the fact that it has more than 800 calories. But even if I had tried to finish it, I wouldn't have been able to because it's super thick, creamy and surprisingly sweet.

You can get this $3.99 shake at any Smashburger location now until September 30.
