Pleyel is a traditional chocolate-almond cake featuring ground nuts. This version is inspired by Nestle's After Eight Mint Chocolate Thins, a flavor profile that is achieved with the addition of mint syrup. To keep the cake light, beaten egg whites are folded into the batter, while powdered and granulated sugars add the the effect, producing a sweet, dense and pleasantly chewy confection. The cake will keep, covered, at room temperature for up to three days.
