A refreshing cake with a hidden ingredient, zucchini! Perfect for the fall season and the buttercream frosting that is light and airy. This Blueberry Lemon Zucchini Cake is a great autumn cake recipe.
Pour the batter into the prepared 8x8 cake pan, and bake for 30-35 minutes or until the cake is set and lightly brown around the edges. Remove and allow to cool completely.
Make the lemon buttercream while the cake cools. Beat together the butter, powdered sugar, and lemon juice. Mix on high until the frosting is creamy and fluffy.
