Prep Time

Total Time
4 1/2


2 cups Land O Lakes® Butter, softened

6 1/2 cups powdered sugar

1/4 teaspoon salt

1/3 cup Land O Lakes® Heavy Whipping Cream

1 tablespoon vanilla extract

Red, orange, yellow, green, blue and purple gel food color

How to make

  1. STEP 1

    Beat butter in medium bowl until creamy. Gradually add powdered sugar and salt alternately with whipping cream and vanilla, beating at low speed until well incorporated. Beat at medium speed until smooth and creamy. Divide frosting evenly among 6 bowls (about 2/3 cup each). Tint frostings red, orange, yellow, green, blue and purple.

  2. STEP 2

    Place each colored frosting into individual resealable plastic food bag; push frosting to one corner. Cut off 1/2 inch from tip of corner. Place 18-inch-long piece of plastic food wrap onto counter surface. Pipe each color onto plastic wrap to form wide 12-inch horizontal lines (using half of each frosting) that are touching.

  3. STEP 3

    Gently roll frosting lines into one large log using plastic wrap. Snip tip off one end of plastic wrap. Place cut-side down into piping bag fitted with size 1M open-star tip. Pipe as desired into rosettes, swirls, rainbows, etc.

  4. STEP 4

    Repeat process with remaining frosting using new piece of plastic wrap. Two batches are recommended so frosting doesn’t get muddied and lose its vibrancy.

Tip #1

Use this frosting technique for a variety of baked goods such as cakes, cupcakes and cookies. We’ve used the technique on our Rainbow Cake and Irish Cream Cupcakes. The cookies in the photo above are our Easy Cut-Out Sugar Cookies.
