Rainbow's Jaekyung seems to have a sweet tooth, and she proudly displayed her confectionary prowess by baking a batch of the sinfully sweet treats known as macarons.

"Prettily wrapped, finished my love macarons," she posted to her Twitter earlier. "Also made the ganache filling inside."

Although the macarons themselves look delicious, Jaekyung's giddy smile as she shows off her culinary panache is equally sweet and heartwarming.

Macarons, not to be confused with the similarly-named macaroons, are a sweet, baked treat made from cream sandwiched between two sugary cookies. They are very, very delicious, and since Jaekyung made these, we can safely assume they'll be infused with even more sugary goodness than usual!
