Mother’s, the maker of the iconic Circus Animal cookies, has launched a new variety with its Mother’s Sparkling Mythical Creature Cookies. The cookies come in four new mythical shapes – unicorn, sea serpents, mermaid and dragons – covered in Mother’s icing in lavender and white with sparkling glitter sprinkles.

To celebrate the release just in time for National Unicorn Day on April 9, Mother’s has partnered with Sprinkles Cupcakes to introduce a limited-edition cupcake inspired by the new cookies. The Mythical Creature by Mother’s will be available for one week only, from April 5-11. The cupcake is a pink, blue and purple sprinkle-studded vanilla cake with a sugar cookie crust and pink vanilla buttercream frosting, lightly sprinkled with silver sugar crystals and topped with a Mythical Creature Cookie.

“We’re so excited to introduce Sparkling Mythical Creature Cookies, the first innovation from Mother’s in nearly a decade – and an extension to the popular Circus Animal cookies,” says Rachna Patel, senior director cookies marketing at Ferrara. “We hope the cookies spark joy and imagination as a fun treat parents can share with kids, and we’re happy to partner with Sprinkles to bring the playful nature of our cookies to life in a new way.”

The Mythical Creature by Mother’s cupcake will be available at all Sprinkles bakeries, through its website and at bakery ATM’s for $5.50-$6.50, depending on the location.

“We’re always looking for flavors that are innovative and will resonate with our guests,” says Charles Craig, vice president of culinary at Sprinkles. “Our limited-edition Mythical Creature Cupcake is a new, fun way to enjoy a nostalgic treat. Last year we baked up a Circus Animal cupcake that was inspired by Mother’s Animal Cookies and our guests loved it. With the release of Mother’s Sparkling Mythical Creature Cookies, we have the chance to develop a new flavor that would wow our guests.”
