Ingredients
  

  • SUGAR COOKIE:
  • 2 1/4 cups all purpose flour
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup butter
  • 2 eggs
  • 1 cup sugar
  • 2 tsp vanilla extract
  • BUTTERCREAM
  • 3 eggs whites
  • 3/4 cups sugar
  • 2 1/2 sticks butter or 1 1/4 cup room temp, cut into Tbsp size chunks.
  • 2 tsp vanilla extract
  • Seeds of 1/2 of a vanilla bean
  • GARNISH:
  • Confetti sprinkles

Instructions
 

  • Preheat oven to 350 degrees F
  • Line 8x8 pan with parchment, set aside.
  • SUGAR COOKIE:
  • Place flour, baking soda, salt in bowl, mix to combine, set aside.
  • In bowl of mixer fitted with paddle attachment cream the butter.
  • Add in the sugar and mix until pale and light.
  • Add in the vanilla, continue to mix.
  • Add in the eggs, continue mixing.
  • With mixer on low add in the flour mixture. Mix until completely combined and dough forms.
  • Scoop dough into pan, with floured hands press dough evenly around the bottom of the pan until evenly covered.
  • Bake 12-14 minutes or until lightly golden.
  • Cool completely.
  • BUTTERCREAM:
  • In medium sauce pan add the egg whites and sugar.
  • On medium heat you are going to whisk egg mixture until sugar is completely dissolved (you can test it by rubbing a small amount between your fingers to test it, it should be completely smooth).
  • Transfer to mixing bowl and with whisk attachment whisk on high until stiff peaks form and mixture is cooled.
  • On low speed add the butter one piece at a time. Mix until well combined.
  • Switch to paddle attachment, add vanilla and vanilla beans, mix until smooth and glossy.
  • ASSEMBLY:
  • Once base is completely cooled and buttercream has been made. Scoop the buttercream onto the base and spread around with an off set spatula. Sprinkle with sprinkles.
  • Tip: you can cut right away but for a cleaner cut refrigerate 10-15 minutes so the buttercream firms up a bit.
