I topped my vanilla sparkler cake with blueberries and strawberries for my red and blue. You could absolutely use patriotic sprinkles, red and blue frosting, you name it! You could even color your cake to have the layers inside be red, white, and blue too! Or if you’re literally out of time then no worries – ask the bakery at your local grocery store for a plain white cake. Then decorate it and add the sparklers!

  1. I love how you used such simple things to dress up a plain white cake. So cute!

    1. Thank you, Tori! :)

  2. This is so pretty, Courtney! Love the sparklers on top, such a fun idea! Wishing you and your family a wonderful 4th of July weekend. xo

    1. Thank you, Cyd! Same to you and yours!

  3. Hi Courtney,
    This is just beautiful! I have a question: how do you get the icing to be a pure white? The buttercream recipe I typically use requires pretty much the same ingredients as you’ve listed above but it always turns out pale yellow. What do you do to get such a clean, crisp white? Thanks for your help!!

    1. For pure white icing, you can use shortening instead of butter. Or you can purchase a store-bought cake ;)
