Box Brownie Shortbread cookies are just one more delicious and easy chocolate dessert. It is just a quick shortbread biscuit base topped with a boxed brownie mix. So good!
Tip : The short bread dough stays crumbly and does not appear to come together like a pie dough, it will seem rather dry, but the dough will come together when pressed into a cake pan.

- 3 sticks unsalted butter
- 3 cups all-purpose flour
- 3/4 cups sugar

Instructions

Layer #1

- Cut up 3 sticks of cold butter into 1/2" slices and add to flour mixture.
- Mix flour and butter with a paddle attachment until the dough resembles corn meal (or you can combine flour and butter in a food processor, pulsing until the flour and butter are combined).

- Remove from oven and allow to come to room temperature.
Serving
- Place the room temperature baking pan in the fridge and cool for 20 - 30 minutes.
