FROSTED RAINBOW SUGAR COOKIE BARS•
Posted on August 28 2015
As beautiful as these frosted cookie bars are they taste even better, they are absolutely delicious! And what's even better they are SUPER easy to make and are quick! This is one dessert you can do over and over again and decorate differently each and every time and you will always get ooh's and ahh's! Go as simple or elaborate with your decorating! Let your imagination run wild and theres a good chance this will become a quick treat you will whip up over and over again!
How cute do these look! For something so simple they look so crazy beautiful! The non-pareils we sprinkled on this batch give a nice little "crunch" to the texture of the treat. There is just something so satisfying about soft frosting paired with the crunch of non-pareils.
To make your cookie bars, start by preheating your oven to 375 degrees. In a medium sized bowl, combine your flour, baking powder and salt. Set aside. In a large mixing bowl, cream together your butter and sugar for about 3 minutes until light and fluffy. Add in your egg, sour cream and vanilla and mix till combined. Slowly add in your flour mixture while stirring until everything is combined.
Line a 9×13 baking pan with parchment paper, snip the corners to have it lay nicely in the pan. Press the dough into the pan evenly.
Bake for 15-17 minutes or until edges just barely start to turn golden, then allow to cool completely before frosting.
Lets decorate these cookie bars! Make your favorite buttercream recipe or in a pinch grab frosting in a can, no judgement here!
Separate your frosting into 6 bowls. We put a drop of coloring on a tooth pick and only added a super small touch. For the pastel look a whole drop was too much color.
Spread each color separately in a row, with each color just barely touching the next. Take your offset spatula (in a pinch you can use a butter knife) and gently with a light touch spread back and forth working your way down through all the colors so they mix together a bit.
We did this about 3 times to get the colors to flow nicely into the next.
Add your sprinkles.
