For birthdays and other special events, this bakery’s fresh blueberry cake recipe is ideal. The layer cake has lovely layers of homemade blueberry buttercream and compote, and it is moist and flavorful with real blueberries. Two bowls of buttercream adorned with a rainbow of colors adorn the blueberry cake. The cake’s upper layer is colored deep purple, while the lower layer is colored light blue. The cake appears luxurious due to the pairing of the two colors. To make the cake look prettier, some non-edible butterflies and edible buttercream flowers are also added.
