Coconut Sugar Cookie Squares! Isn’t a thick frosted sugar cookie one of the best comfort foods out there? I love sugar cookies and I love sugar cookie squares even more because they are quicker and easier to make (with less clean up) but they taste just as good as the individual cookie. I know I post a lot of sugar cookie recipes, it’s just one of my favorites so it’s likely you’ll see even more variations on it in the future.

Have I told you yet this Coconut Buttercream Frosting is my all time favorite frosting? I made it to frost the coconut cupcakes I made a few days ago and it got me thinking of what else I would love to use it for. It is highly addictive stuff! I could sit and eat it by the heaping spoonfuls.

Now, imagine a fluffy, sweet, coconut infused sugar cookie covered with silky smooth, fluffy, melt in your mouth coconut frosting – and this is what you get. Let’s just say it’s very likely to be one of the best sugar cookies you will ever eat! I know I’m in love =). Enjoy!

Coconut Buttercream Frosting


  • Preheat oven to 375 degrees. Process 1/2 cup shredded sweetened coconut in a food processor until finely ground (this took a few minutes in my mini food processor). In a mixing bowl, whisk together flour, baking powder and salt. Whisk in ground coconut, set aside.
  • In the bowl of an electric mixer, whip together butter and sugar until pale and fluffy. Stir in egg, egg white and vanilla. Add in coconut milk and sour cream and mix until blended. Slowly add in flour mixture and mix until combine. 
  • With buttered hands, gently press dough into an even layer in a buttered 13x9 baking dish. Bake 18 - 20 minutes until edges are lightly golden. Allow to cool completely then frost with Coconut Buttercream Frosting and sprinkle with additional optional shredded sweetened coconut. Cut into squares and store in an airtight container.

    My sister in law got me started on pinterest and you were the first blog with a recipe i wanted to try that i found. As i looked through some of your other recipes i was thinking “wow, these would be great recipes to make out of food storage!” Then I saw that you were LDS and i just had to laugh… Miles apart and yet we still find each other! I’m in Independence MO. Indep 1st ward… Anyway, I have now tried several of your recipes and i have yet to find one that i don’t just love. I made your coconut sugar cookies for a pot luck dinner and all the samoans in my ward had them eaten before anyone knew they were there… lol… Thanks so much for your blog and your recipes! I look forward to trying many more!!!

    I made these last night and thought they were too sweet, silly me, this morning took them to work…I put a dark chocolate almond in the middle of each one. They were gone. I tasted them today and they are to die for!
