  • ½ cup softened butter
  • ½ cup granulated sugar
  • 1 egg
  • 1 teaspoon vanilla
  • 1 cup all-purpose flour
  • ½ cup whole wheat pastry flour you can use any other type of whole wheat, but I prefer the whole wheat pastry. If you don't want to do wheat, switch to all white flour.
  • dash salt


  • 6 ounces softened butter
  • 2 ½ cups powdered sugar
  • ½ teaspoon vanilla
  • milk to consistency
  • patriotic sprinkles


  • Preheat oven to 300 degrees.
  • Line a 9×9 baking pan with parchment and set aside.
  • In a small bowl, combine the all-purpose flour, whole wheat pastry flour, and salt. Set aside. 
  • Cream the butter and granulated sugar for the cookie bars together. This should only take a minute.
  • Add in your egg and vanilla. Mix to combine. Add in your flour mixture and again, mix to combine.
  • Put it into your parchment-lined pan and press to even out.
  • Place in the oven and bake for about 17 minutes.
  • Remove from the oven and allow it to cool for 5 minutes.
  • Then, using the parchment paper, remove from the pan and set on a cooling rack. Cool them for another 25-30 minutes.
  • While they are cooling, mix your icing
  • Add your powdered sugar, vanilla, and butter to a bowl. Add in 2 tablespoons of milk to start
  • Mix well, than add in more milk if needed. I like my icing on the thick side, so it was good for me.
  • Spread over your cooled bars, then sprinkle generously with your patriotic sprinkles.
  • These are delicious served right away. They also hold really well for several days in the fridge too. They don't last long here, but have been good for up to 3 days.
  • They are best in an airtight container or wrapped with saran wrap.
  • Now, sit back and enjoy. You deserve it!


  • Do not overmix. It is really important to not overmix them or you will have really tough cookies. I recommend mixing only to combine.
  • I used whole wheat flour in this, but I highly recommend that you use whole wheat pastry flour. Whole wheat pastry flour is a lower protein flour, and so it makes a much more tender texture when baking with it.
  • I like to bake my cookies in a metal pan. I prefer the way these pans bake as opposed to glass pans. In my opinion, the heat distributes more evenly.
  • These cookies have a short baking time, and the worst thing you can do for these cookies is to overbake them. They only take between 15-18 minutes, so just be careful!
