Starbucks devotees everywhere may be waiting with bated breath to find out when the PSL will be back in stores, but in the meantime, there's one more summer drink to try before the season ends: the Blueberry Pie Frappuccino.

I spotted the drink on display at a Downey, CA, Starbucks and by all accounts, it's a local drink (Starbucks has yet to confirm where else, if anywhere, it can be found). However, based on the ingredient list, it can be recreated as a secret menu item of sorts at other stores.

Per the chalkboard, the dessert-flavored Frapp is made with a Vanilla Bean base, blueberry, and graham cracker topping. It seems to combine the blueberry juice from the Iced Blueberry Black Tea currently on menus and the graham cracker topping from the S'mores Frappuccino—so as long as your local Starbs serves those two drinks, you should be good to go.

A little Twitter stalking informed me that at least a few people have hacked this flavor themselves—some even added white mocha sauce into the mix, too.

An Instagram post from 73 weeks ago shows a tray of little mini Blueberry Pie Frappuccinos from Starbucks with a note to ask for "a Vanilla Bean creme Frappuccino with fresh blueberries blended in, a splash of lemonade, and brown sugar."

All this is to say that the Starbucks world is your oyster...and a pie-flavored Frapp sounds GOOD.

[Editor's Note:] Per a Starbucks spokesperson, the Blueberry Pie Frappuccino was created by a barista at the Downey Starbucks and was available for a short time at that particular store. However, customers can always customize or create their own drink as long as they know the recipe.
