Ingredients
  

  • 2 cups all-purpose flour King Arthur or Bob’s Red Mill
  • 1/2 cup granulated sugar plus extra for sprinkling
  • 1 cup unsalted butter room temperature (Land O Lakes recommended)
  • 1 tsp pure vanilla extract Nielsen-Massey if you like rich flavor
  • 1/4 tsp fine sea salt Diamond Crystal
  • colored sanding sugar or mini festive sprinkles Optional

Instructions
 

  • Preheat oven to 350°F (175°C). Line an 8×8-inch square pan with parchment paper, leaving a 1-inch overhang on two sides—this makes pulling out the bars a breeze.
  • In a stand mixer fitted with a paddle attachment (or using a handheld mixer), beat the butter and 1/2 cup sugar on medium speed until pale and fluffy, about 2–3 minutes.
  • Scrape down the bowl, then add vanilla extract and sea salt. Mix briefly until combined.
  • Lower the mixer speed and slowly add flour. Stop mixing when you see no streaks; don’t overwork or the Bars risk getting tough.
  • Dump the dough into your prepared pan. Use an angled spatula or the bottom of a glass dipped in sugar to press it evenly.
  • Lightly brush the top with a bit of water, then scatter colored sanding sugar or sprinkles. Cover and chill for at least 15 minutes—this helps the Bars hold their shape.
  • Slide into the oven and bake 20–25 minutes, or until edges just turn golden. The center may look pale, but it will firm up as it cools.
  • Let the pan rest on a rack for 10 minutes, then use the parchment overhang to lift your delicate slab out. Transfer to a cutting board and, while still warm, slice into 16 squares (or get creative with wedges).
  • Let the bars cool completely before packing or serving.

Notes

Keep bars in an airtight container at room temperature for up to 5 days, or refrigerate for 7 days to prolong freshness. For longer storage, freeze bars for up to 3 months—wrap each stack in plastic wrap, then tuck into a freezer bag.
