Blueberry Lemon Layer Cake ~ a vibrant layer cake recipe bursting with juicy berries and fresh lemon, frosted with a tangy lemon buttercream frosting. Ideas for decorating this blueberry lemon cake You might decorate the top with edible flowers purple pansies would be perfect. You could simply mound fresh blueberries in the center, accented with fine strips of lemon zest. A shower of powdered sugar helps define the berries and make them pop. You could also do it like I did but substitute small mint leaves for the thyme. I think it would be really nice to slice some of the berries in half crosswise to show off their beautiful interiors. If you do this, slice them just before serving.
