Ingredients

Crust

  • 2 cups all purpose flour
  • 4 tbsp powdered icing sugar
  • 1 cup unsalted butter cold, cubed
  • 1-2 tablespoons cold water optional

Filling

  • 1/2 cup butter unsalted
  • 3 cups brown sugar lightly packed
  • 4 large eggs
  • 2 tbsp white vinegar
  • 1 tbsp vanilla
  • optional: 3/4 cup raisins

Instructions

  • Line a 9x13" pan and line with parchment paper or spray with non stick. Preheat oven to 350 degrees F.
  • In a large bowl, combine flour and powdered sugar.
  • Cut butter into icing sugar and flour with a pastry cutter or your hands until pea-sized lumps of butter remain. When you grab a handful and squeeze, you want it to hold together. If it doesn't hold together, add 1-2 tablespoons of water.
  • Dump flour mixture into pan and press down evenly to form a crust. Bake for 10 minutes.
  • Meanwhile, prepare your filling. In a medium bowl, melt butter in the microwave.
  • Whisk in brown sugar until smooth. Whisk in eggs, one at a time, then add the vinegar and vanilla. Stir in raisins if using.
  • Pour over crust and bake another 25-30 minutes until filling is set or almost set -- a slight jiggle is fine but you don't want a lot of movement. Cool to room temperature and refrigerate several hours before slicing.
