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
- Base Layer Preheat the oven to 350F degrees. Line the pan with parchment paper, leaving an overhang around the edges.
- Base Layer In a large bowl beat the butter and powdered sugar until fluffy.
- Base Layer Mix in the flour – the mixture will be thick.
- Base Layer Press the mixture into the bottom of the pan.
- 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.
- Filling Layer Make the filling as the base layer is baking.
- Filling Layer Beat the butter, brown sugar and flour until evenly combined.
- Filling Layer Beat in the eggs and vanilla extract.
- Filling Layer Mix in the corn syrup and vinegar. Stir in the optional raisins, currants or walnuts.
- Filling Layer Pour the mixture over the gently baked crust.
- 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.
- Cooling Remove from the oven and cool completely before slicing for clean cuts and to ensure that the bars are set.
- 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.
