They're a staple of kids' Easter baskets, but Cadbury Creme Eggs have fans of all ages. And a new product inspired by the treat is made for adults exclusively. As Delish report, Cadbury is teaming up with Goose Island Brewery to produce a Creme Egg-flavored beer just in time for spring.

This year marks 50 years since the Cadbury Creme Egg's debut. To celebrate the goo-filled chocolate egg's golden jubilee, Cadbury and Goose Island Brewery have collaborated on a Golden Goo-Beer-Lee Creme Stout that's only available for a limited time.

The beer is made from malted barley, oats, wheat, and milk sugar to recreate the candy's creamy flavor profile. Vanilla beans and cacao nibs are added to the brew to bring the taste to a new, indulgent level. The beverage, according to Goose Island's master brewer, is meant to evoke the rich sweetness of Cadbury Creme Eggs without sacrificing drinkability.

Cadbury sold its first hollow chocolate egg in 1875, but the Cadbury Creme Egg with its white-and-yellow fondant center didn't hit stores until 1971. Since then, the UK brand has sold candy eggs filled with chocolate, caramel, and Oreo creme. This marks the first time the Cadbury Creme Egg name will be used to sell alcohol.

The Golden Goo-Beer-Lee Creme Stout will be available in packs of two starting at 11 a.m. on Monday, March 8, from the Goose Island Brewery website. The first batch went fast, and this last round is expected to sell just as quickly.
