Rainbow Cookie Cake with Rainbow Chip Frosting!

Mini Rainbow Cookie Cake

One of the fondest memories of our youth is birthdays. More specifically, the very special birthday cake that mom made for you.

One thing I can remember very fondly from my childhood is Rainbow Chip frosting on my yellow cake. There was something so darn amazing about those little rainbow pieces scattered all throughout the frosting!




Rainbow Cookie Cake with Rainbow Chip Frosting!

I decided to make my very own Rainbow Cookie Cake. Rainbow colored sugar cookie with Rainbow Chip frosting between each layer. So fun and delicious!

Recipe adapted from Sugarbelle.

Tips for Success:

I used gel food coloring to achieve the vibrant color, but you can certainly use liquid food coloring. Just make sure that your have extra flour on hand should the dough become too sticky.

After my dough chilled I rolled out the first color on the counter then used a 4-inch round cookie cutter to cut out each cookie. I baked three cookies on a cookie sheet at a time.

Rainbow Cookies

These cookies are big! The recipe will only make one of each color. (But you will have a little dough left over… enough to make a mini cookie cake) If you would prefer, you can use a small round cookie cutter and make numerous individual Rainbow Cookie Cakes. (It is the exact same process and will yield 5-7 mini cakes)

If you want to make more than one cookie cake at a time then double the cookie recipe.

When ready to assemble the cake:

Place a cooled PURPLE cookie on cake stand. Place a dollop of about 1 tablespoon of Rainbow Chip Frosting in the center. You may need a little more, but go sparingly. As the layer stack up more pressure will be applied and if you have too much frosting it will spill out. Continue with BLUE layer next (be careful! cookies are fragile) and then cover in 1-2 tablespoons Rainbow Chip Frosting. Continue up in reverse rainbow order and then place a big dollop on top! Cover with more sprinkles or rainbow chocolate chips.

PRO TIP: Chill until ready to serve! Once ready to serve, simply cut pieces out of the cake just like you would a normal cake. I used a sharp knife and kept my hand very steady. If you do not chill it, the cookies will want to slide.

If you are making the smaller version then each individual gets a smaller Rainbow Cookie Cake.

My kids were absolutely enamored with these stacks of rainbow cookie awesomeness. I cut the pieces small because a little goes a long way!

I had so much fun creating a Rainbow Cookie Cake! I have a feeling there are many more rainbow desserts in my future!
