Ready for any celebration, Funfetti Frosted Sugar Cookie Bars are super soft, loaded with sprinkles, and topped with the creamiest Buttercream Frosting.
Sugar cookies can come in so many shapes and sizes and have the best classic flavor that brings us back to all our childhood celebrations. Most sugar cookies are made to be scooped or rolled out and cut into shapes. They can be enjoyed plain or can be decorated with royal icing or buttercream frosting.
There are so many ways to love a sugar cookie, including these Funfetti Sugar Cookies, but I have discovered my true love for Sugar Cookie Bars. These keep things simple, serve a crowd without all the time of individually scooping or cutting out shapes. These Sugar Cookie Bars are made with one batter spread into a square cake pan, baked and frosted with my all-time favorite Buttercream Frosting. The rich and classic Buttercream complements the Sugar Cookie Bars perfectly and takes them to the next level. Rainbow sprinkles are a great addition to make these festive and fun for any celebration!

What Is The Difference Between Sugar Cookies and Shortbread Cookies
When I am making shaped and decorated cookies, my go-to is my famous Shortbread Cookie Recipe that I have made for so many years. They are super buttery, not overly sweet and glazed with smooth royal icing, and very different than a Sugar Cookie. Shortbread is typically made with sugar, flour, butter, and an egg keeping the flavor simple and focusing on the butter. Sugar Cookies bring back memories of childhood and I love the classic sugar cookie made into bars topped with a delicious Buttercream Frosting. Sugar cookies have less butter than a traditional shortbread cookie, they are made with baking powder and baking soda for a more cake-like texture and this recipe is made with a dash of almond extract.
Tips and FAQs for Sugar Cookie Bars
- Make sure all the frosting ingredients are room temperature so that everything combines perfectly.
- If you're not serving the sugar cookie bars immediately, store them in an airtight container.
- These bars can be stored for 2-3 days.
Yes, this is a great way to add another colorful touch to the sugar cookie bars! Add whatever food coloring you want until you get the desired color.
Yes you can absolutely make the frosting in advance to save some time! Just refrigerate it until about 30 minutes before you need to use it so it can soften up.
