It’s promos galore this year for synth-pop duo Tegan and Sara! After already providing the theme song “Everything is AWESOME!!!” for the upcoming Lego Movie, now the pair is behind the jingle for the latest 30-second Oreo commercial featuring its new flavors.

While happily singing the opening line of “Wonder if we tried a new thing, looked inside see what we can bring,” Tegan and Sara reinforce Oreo’s ‘Wonderfilled’ slogan.

The latest limited-edition cookie flavors Cookie Dough and Marshmallow Crispy will be available in stores Feb. 3.
