First step is to grab all of your ingredients and set them aside. Preheat your oven to 350 degrees Fahrenhiet.
Grab a 9x13 baking tray that is semi deep, deeper than your typically cookie sheet. Line this with parchment paper.
Start by combing your butter and icing sugar in an electric mixer. Allow this to mix on medium speed for a few minutes until well combined.
Add in your salt and vanilla bean paste.
Combine your flour and cornstarch in a separate bowl and then gradually add to the wet mixture until well combined.
Transfer the well combined dough into your lined baking tray. Flatten out with a spatula until evenly distributed and then add your preferred sprinkles all over the top.
Bake this for about 33-35 minutes until it is golden on the edges and set in the middle.
Once cooked, allow it to cool and then slice in to your desired bars. I love slicing these into little two bite pieces!
