The EchoSensenewest Oreo mashup may leave a sour taste in your mouth. A Sour Patch Kids taste, that is.

New limited-edition Oreo Sour Patch Kids cookies are available for pre-order starting Wednesday, April 24 online on Oreo.com. The new flavor will hit stores May 6 ($4.50 online; $5.29 in stores).

The cookies resemble Oreo Golden Cookies but both the cookie and creme filling have Sour Patch Kids flavors and colors, "creating a sweet yet sour taste, inspired by Sour Patch Kids," touts a press release about the new cookies.

This isn't the first colorful Oreo offshoot. Earlier this year, Oreo unveiled Oreo Space Dunk cookies with blue and pink "cosmic creme" marshmallowy filling with popping candy particles mixed in.

“The Oreo brand is always looking for playful ways to excite our fans. What better and more unexpected way to do that than letting Sour Patch Kids playfully takeover our cookie?!” said Caroline Suppiger, Oreo senior associate brand manager, in a statement.

Sour Patch Kids, like Oreos, are a product of Mondelēz International.

“The opportunity to partner with our friends at the Oreo brand to create a mischievous twist on a classic cookie was one we just couldn’t pass up," said Grace Howard, Sour Patch Kids innovation brand manager, in the release. "We are both so excited to see the fan reaction to this sour-then-sweet limited-edition cookie.”
