Rainbow Cookies

Do you believe that there’s a pot of gold at the end of every rainbow?

I’m not quite certain myself. But what I do know is that with every bite of these cookies, you’ll get a burst of delicious sweetness.

I am so thrilled to present to you my Rainbow Cookies. For me, the best part is the mini marshmallows: it offers a flavor and texture that not every cookie can boast.

When my daughter laid eyes on these Rainbow Cookies, she was amazed. She told me to bake more! I only agreed because I had so much fun making the first batch.

Ingredients:

Rainbow Cookies Recipe

Your favorite recipe for sugar cookies (enough to make at least one dozen 3-inch circular cookies)

Circle cookie cutter, 3 inches in diameter

½ stick butter, softened

1 cup icing sugar

1-2 tbsp milk

2 drops sky blue gel food coloring

2-3 oz. red fondant

2-3 oz. orange fondant

2-3 oz. yellow fondant

2-3 oz. green fondant

2-3 oz. blue fondant

2-3 oz. violet fondant

24-40 mini marshmallows

Yields: One dozen decorated cookies

Directions:

Preheat your oven according to your cookie’s recipe’s directions. Line a cookie sheet with parchment paper.

Rainbow Cookies Recipe

Roll out your sugar cookie dough so that it’s about ¼ of an inch thick. Using your cookie cutter, cut out 12 circles.

Place each cookie on a lined cookie sheet and bake according to recipe’s directions.

Allow the cookies to cool completely on a cooling rack.

In a small bowl, beat together butter, icing sugar and milk using an electric mixer. These ingredients will make up your buttercream frosting.

Once the ingredients are well-combined, smooth and form semi-stiff peaks, add blue gel food coloring.

Mix until it’s completely tinted.
