Today's super fun cookie recipe has me wishing for spring to arrive!

It's been a super cold winter in Minnesota and all we want and need is some sunshine and rainbows.

I might not be able to bring warm sunshine, but I have some delicious rainbow goodness for you!

How cute are these cookies?? 

The dough is completely homemade and is a recipe that's been used by my family for over 20 years. It turns out perfectly every time and we always make them for the holidays. They are SO delicious!!

I chose to use store bought frosting, but you could always use your favorite homemade frosting too! We LOVE this cream cheese frosting.

The prep is pretty simple and you'll want to make sure to grab a rainbow cookie cutter if you don't already have one.

The decorating is the fun part! These cookies are simple enough for almost any age to help with and they'll have so much fun eating them once they're done decorating. 

You'll want to make these for parties, especially in the spring and summer, use them in nature or weather themed lessons or if you're just craving a tasty, sweet snack.

I hope you have as much fun with these cookies as we did!

Recipe tips:

• The good thing about sugar cookie dough is that you can actually prepare it in advance and freeze it. Once my cookies are completely cooled, I freeze them on a sheet pan, and once frozen, I transfer them to a freezer-safe container. When I want to pull some out to frost and serve, I thaw them flat on a baking sheet.

• I always bake one sheet at a time in the center rack of the oven. Have an extra baking sheet available, so you can have the next batch ready to go in the oven.
