Ingredients

For the cookie bar:

  • 1 cup salted butter room temperature. you can use unsalted butter if you prefer!
  • 1 ½ cups granulated sugar
  • 2 tsp vanilla extract
  • 1 egg + 1 egg yolk
  • 2 ½ cups all-purpose flour
  • ½ tsp kosher salt
  • ¼ tsp baking soda
  • ½ tsp cream of tartar
  • 2 tsp corn starch

For the caramel:

  • 2 cups granulated sugar
  • ½ cup heavy cream
  • 10 tbsp salted butter
  • ½ tsp kosher salt
  • flaky salt for garnish

For the ganache:

  • 1 ¼ cups milk or dark chocolate baking chocolate or chocolate chips. I prefer Ghirardelli milk chocolate
  • cup heavy whipping cream

Instructions

For the sugar cookie bar:

  • Preheat the oven to 350° and grease and line a metal 9×13 pan with parchment paper. In the bowl of a stand mixer combine the butter and granulated sugar. Mix until combined. Add in vanilla and egg and egg yolk, and mix until incorporated.
  • While the mixer is on low add in the flour, salt, baking soda, cream of tartar and corn starch. Mix until just combined. Scoop batter into the prepared pan and use a spatula or lightly wet your hands to evenly press the dough into the pan. Poke dough several times with a fork. Bake or 20-22 minutes, or until the edges are golden brown. Remove from the oven and allow to cool completely before assembly.

For the caramel:

  • Add sugar to a saute pan over medium-high heat. The sugar will look normal for the first few minutes, stir occasionally with a metal whisk. Then it will start to clump and melt, turning a deep amber color. Stir continuously until all of the sugar is dissolved. Once melted, stir in butter, one tablespoon at a time. After the butter melts completely, slowly drizzle in warm heavy cream until completely combined. The mixture will bubble and steam up each time you add the heavy cream so be careful! Remove the caramel from heat and stir in the kosher salt.

For the ganache:

  • Break up the chocolate and place in a medium sized bowl. Heat cream for 30-45 seconds in the microwave or until it bubbles. Pour over the chocolate and let sit for 3 minutes before whisking. If the chocolate doesn’t completely melt, microwave for 20 additional seconds and whisk in between until smooth. Allow to cool for 10 minutes.

For assembly:

  • Once the cookie bars are completely cooled pour caramel on top and evenly spread. Add to the refrigerator to set for 15 minutes.
  • Pour ganache on top of the caramel and spread to evenly coat. Sprinkle on flaky sea salt. I let these set up for an additional 30-60 minutes in the refrigerator to make it easier to cut into slices! Store in the refrigerator for up to 5 days.
