Here's What You'll Need
all-purpose flour, sugar, rosemary, salt, unsalted butter
Place all ingredients except butter in a food processor and pulse 5x. Add cubed butter, then pulse until the dough starts to come together and looks like clumpy, wet sand. It should not be smooth!
Press into an ungreased 8" square pan, using your hands to flatten into an even layer.
Prick the dough with all over with a fork, then bake at 350F for 45 minutes.
Cool on a wire rack for 5 minutes, then slice into 12 bars and serve warm.
