Ingredients

Units Scale

Base Layer

  • 1 cup unsalted butter (softened)
  • 1/2 cup powdered sugar
  • 2 1/4 cup all-purpose flour

Filling Layer

  • 1/2 cup unsalted butter (softened)
  • 1 cup brown sugar (light or dark)
  • 2 tablespoons all-purpose flour*
  • 4 large eggs
  • 2 teaspoon vanilla extract
  • 3/4 cup dark corn syrup*
  • 2 tablespoons white vinegar*
  • 1 cup raisins, currants or chopped walnuts – optional (I use 1/2 cup currants and 1/2 cup chopped walnuts)

Instructions

  1. Base Layer Preheat the oven to 350F degrees. Line the pan with parchment paper, leaving an overhang around the edges.
  2. Base Layer In a large bowl beat the butter and powdered sugar until fluffy.
  3. Base Layer Mix in the flour – the mixture will be thick.
  4. Base Layer Press the mixture into the bottom of the pan.
  5. Base Layer Bake in the preheated oven for 15-20 minutes or until the top looks set and is a pale, golden color. Remove from the oven and leave the oven turned on.
  6. Filling Layer Make the filling as the base layer is baking.
  7. Filling Layer Beat the butter, brown sugar and flour until evenly combined.
  8. Filling Layer Beat in the eggs and vanilla extract.
  9. Filling Layer Mix in the corn syrup and vinegar. Stir in the optional raisins, currants or walnuts.
  10. Filling Layer Pour the mixture over the gently baked crust.
  11. Filling Layer Bake in the preheated oven for 30-35 minutes, or until the top looks set and if you give the pan a nudge the filling layer doesn’t look liquidy.
  12. Cooling Remove from the oven and cool completely before slicing for clean cuts and to ensure that the bars are set.
  13. Slicing When ready to slice, lift the bars out of the pan using the overhang of the parchment paper. Place on the cutting board and slice using a sharp knife. If the edges seem too crispy, simply slice off the edges.

Notes

  • The orchard fruit and nut mix is optional; you can use raisins, currants or chopped walnuts, or a combination.
  • Be sure to cool completely before slicing for clean cuts and to ensure that the bars are set.
  • If edges seem too crispy after baking, slice them off for a softer texture.
