GSC and Cherry Pie are the parents most often credited behind Birthday Cake, and this all in one lives up to the party in its name. Fitting for a brand celebrating its tenth birthday in 2026, Rove builds it from melted diamonds and natural botanical terpenes, set in a pod on a reusable battery that recharges once the first pod is done. Open it and the smell is yellow cake fresh from the oven with a thick swipe of buttercream. The draw is fluffy and light, like a fork sinking through the layers. The finish brings a colorful sprinkle crunch and a whiff of just blown out candles, with sweet frosted vanilla lingering around the corner.
