Butter Tart Bars

Buttery delicious bars with walnuts and raisins.


  • 1 pkg Kathie’s Bakery Scratch Oatmeal Shortbread Cookie Mix
  • 1 ½ Sticks salted butter (¾ cup), at room temperature
  • ½ Cup salted butter, at room temperature
  • 1 ½ Cups brown sugar
  • 2 Large eggs
  • 1 Tsp. Vinegar
  • 1 Tbsp. vanilla
  • 1 Cup raisins
  • ½ Cup chopped walnuts
  • 1 Cup coconut (optional)


Preheat oven to 325°F.
In large mixing bowl, use your hands to combine butter and Kathie’s Bakery Scratch Shortbread Cookie Mix until the dough holds together when lightly squeezed. (the warmth from your hands is important)
Pat dough into an un-greased 9×13” cake pan and then use a fork to poke some holes in crust. Bake for 15-20 minutes or until crust turns slightly brown around edges.
Make the Topping: the topping is so easy! Place ½ cup butter and brown sugar in a large bowl and beat until blended. Add vinegar, vanilla, raisins, walnuts and coconut (if using, any combination works) and stir until totally combined. Pour on top of warm crust and bake 30-40 minutes until bubbly and a little crusty on the side and edges.
