This Simple Popsicle Sheet Cake is the Dessert Your Summer Needs

  • I come from a family of cake eaters – we love any form of it. But sheet cakes are always a big win because they are so easy to make and you can get creative with them. I recently discovered this popsicle sheet cake and it’s my new favorite. Whatever occasion you’re celebrating this season – whether its a birthday, graduation, or just your average weekend BBQ – this simple popsicle sheet cake is the perfect dessert! Simply bake your favorite cake recipe (my sheet cake recipe is below) in a large rectangular pan, and you already have the perfect foundation for a popsicle shaped cake. Layer it, frost it with colored frosting and add a cardboard popsicle stick! It’s the easiest cake decorating project for your summer parties, and pairs perfectly with a scoop of ice cream or a dose of sprinkles.


    The one-layered cake often comes with a thick layer of frosting on top, too. It’s a no-fuss, no-frills dessert that easily feeds a crowd. While it makes sense for big celebrations, it’s a good choice for smaller ones too ― because sometimes leftover cake can taste even better the next day! Follow along with this step-by-step tutorial and learn how to make this popsicle sheet cake just in time for summer.

    • Baked rectangular cake, about 9×13 in (recipe below)
    • Vanilla frosting (recipe below)
    • Food coloring
    • Knife
    • Offset spatula
    • Cardboard


    Step 1: Remove cooled 9×13 inch cake from pan. Carefully move the cake to a large cake board or a cutting board.

    Step 2: Mix food coloring into the frosting and stir until desired popsicle color is reached.

    Step 3: If desired, level the cake into two layers and fill with vanilla frosting (optional).

    Step 4: Use a knife to cut a curve out of one corner of the cake to make it appear like a bite has been taken out.

    Step 5: Cover the entire cake with a thin layer of frosting, or a crumb coat. Refrigerate at least 30 minutes.

    Step 6: Apply another thick layer of frosting to the cake, smoothing along the top and sides with the spatula.

    Step 7: Cut a strip of cardboard about 2×5 inches with one end curved. Insert the straight end into the uncut end of the cake to resemble a popsicle stick.
