Shamrock Shake Cookies

Shamrock Shake Cookies

St. Patrick’s Day is this week, which means it’s all about green and gold! Around this time of the year the Shamrock Shake shocks us all into a creamy sugar high. According to Wikipedia, the shake was apparently first created to be a lemon/lime, and was later adapted with mint. So I thought I’d create a minty, creamy, and lusciously cool cookie that resembles that refreshing shake. So the Shamrock Shake Cookies were made and then girls and I had a had a blast decorating them. And as luck of St. Patty’s week would have it, Bea and Tilly are all over this post and about to melt your hearts!

The Cookies

These Shamrock Shake Cookies start with a cookie dough that I slightly adapted from my Vanilla Frosted Soft Sugar Cookies. These cookies are a cross between cheesecake, sugar cookies, and the most lusciously delicious dream dessert you can think of!

First, make sure that all of your ingredients are room temperature. You are going to use a mix of butter and cream cheese.

I always give this a quick whip first with my hand mixer to blend it prior to adding the sugar.

Cream butter and cream cheese

This batch will give you a dozen large cookies. We went with the hand mixer for this recipe. Once your butter and cream cheese get well aquainted, add in your sugar and cream for about 3 minutes.

Then it’s time to get these minty and green! Add a combination of peppermint and vanilla extract with your egg. At this time, you will also add an egg and your green food coloring. I tried to keep with the pastel color that the true Shamrock Shake has, but you can always kick it up a notch.

After creaming it, you will get this lovely blast of color and peppermint aroma!

It already looks like a Shamrock Shake! Then you will incorporate your dry ingredients. Tilly helped with this part.

Then gently fold it all together.

Then drop them by the tablespoon onto a parchment lined baking sheet. As they bake they will puff up. Then they will deflate a bit as they cool. Cool completely before frosting. You also have the option to dust these with sugar prior to baking if you prefer these Shamrock Shake cookies without Mint Buttercream Frosting. But why would you want to skip Mint Buttercream Frosting?!

Mint Buttercream Frosting

A Shamrock Shake Cookie isn’t complete without a creamy and cool frosting to top it all off! This frosting is whipped up in a jiffy. It’s fluffy, minty, and delicious! They also mimic the look of the whipped cream that tops an actual Shamrock Shake.

Once your cookies are completely cool, it is time to decorate! First, frost the Shamrock Shake cookies with a generous layer of the Mint Buttercream Frosting.

Then, decorate any way you choose with sprinkles and other decorations. We cut out a four leaf clover and used gold and green glitter.

Then enjoy your cookies and have a happy, safe St. Patrick’s Day!
